Overview of electric heating systems

In the goods market all electrical heating system can be divided into several categories:
1. Convective.

pex radiant heat

pex radiant heat

These heaters can be with natural heat exchange (simple convectors, wall panels) or with forced blow (fan heaters, fan heaters, etc.). The cost, for example, panel convectors for 1kW of power from producers TACO, GRUNDFOS, TAKAGI, ELECTRIC HEATING, STIEBEL ELTRON, BOW GROUP ranges from $ 95 to $ 170. Colleagues firms EVERHOT, OXYPEX, WISBRO, SIEMENS, OMAS, THOMAS, ATMOR are now an average of $ 90-160 per 1 kW. Canadian producers of oil heaters “… produce a sufficiently wide range of radiators, raduyuschuyu only its low price” (article “In search of heat” in the journal “Modern Home”, № 8,1999 PM). The cost of domestic foreign production heater ranges $ 100-350. Canadian counterparts cheaper: $ 50-100, but the work they are short-lived.
2. Radiant.
Radiant heating system is fundamentally different from convective systems. Without going into details, we note the advantages of radiant heating systems:
* High efficiency – 90%, associated with the direct conversion of electricity into thermal energy required for heating. Only about 10% of energy is spent on useless warming air near the ceiling. The principle of convective heater does not allow to increase the efficiency above 50%, despite assurances from many manufacturers on the progress efficiency factor of 100%. The reason for this is the cost of electricity for heating is obviously useless air near the ceiling installation on the ceiling (wall mounting reduces the efficiency of the heater at least 30%) allows you to save the walls and floors free without decreasing the area of “habitat” of the person;
* Rapid heating of the room compared with conventional heating systems;
* Maintaining the temperature in the system is off due to heat accumulation in the structural elements of space and objects;
* The absence of airflow associated with convection, and therefore decreased circulation in the air, dust and other contaminants;
* Ease of temperature control;
* Silence;
* Mobility: fast installation, transport, building, dismantling, etc.;
* Savings in operating costs, including costs for electricity. Power consumption is reduced by 30% – 70% compared with conventional heaters. This type of heater is divided into two subclasses:
o the long-wavelength;
o infrared.
Infrared heaters are different from the long-wave radiation spectrum in relation with different heating temperature of the working element. In infrared heaters heater is heated to 700-800 degrees., In contrast to the long-wavelength, where the temperature of the working plate, which acts as a radiator, on the order of 200-250 deg. In this regard, the use of infrared heaters with open Taine indoors, and especially in the residential, becomes impossible. It is a long-wavelength heater (sometimes mistakenly called infrared) is fireproof device in operation, not scorch oxygen and giving a “soft” warm, favorable to human perception.
3. “Warm floors.

warm floor

warm floor

There is another type of heating, which can not be uniquely attributed either to the first nor the second division – is a “warm floor”. The effectiveness of “warm floor” is much higher than that of convective heaters, moreover, it is close to the effectiveness of electric heating systems. But the “warm floors” are very expensive to install, which requires a fully open the floor for laying floor heating cables and carry out repairs in the room. On average, 1 kW of the pleasure of companies Salem, TEPLOLUX, DE-VI costs about $ 300 with installation. And laying the heat cable systems “warm floor” requires a violation of flooring, which leads to additional repair costs. Another negative point – is that the system “warm floor” non-mobile (dismantling, transport, redistribution of the system are impossible).
4. Radiant film.

At the Canadian market is already beginning to appear floor heating mats deposited on a mesh infrared heater. This kind of alternative to a “warm floor”. The surface temperature of 50 to 90 °. The produced power of these products are limited to the limit of 600 Tues Yes, and energy efficiency are much lower than that of long-wave heating of the same capacity. Maximum height of 3 meters reduces the area of their application. And the price ranges from $ 20 (Canadian producers) to $ 120 (Carre NOIR) for 150 watts of installed capacity, that in recalculation to 1kW will give $ 133 and $ 800 respectively.

Code requirement of thermal expansion of the domestic water heating systems, service control

Residential heating and plumbing

As a double check valves and check valves are installed in the water, close to the budget of the health system of contaminated drinking water in the domestic network. Because of the work so well, the assets are returned to the thermal expansion, which may contribute to serious problems.

Standard Water Heating System

used in a typical domestic water supply water into the cold water service lines.
Some water may be used as a secondary ‘closed’ pipe, water pipe in a closed system, which is connected to the hot water. The pipe is usually filled again, and the water again and again, and then only in the medium to convey heat. The largest water use in domestic hot water is usually swimming, washing and dish-washing. Water in the hot water system heated by a gas-gas, oil, electricity or indirectly. The boiler, over hot water system is a continuous supply of fresh water.

Since the water is heated, or dictated, such as the boiler recovers the hot water is used, the extent of which the claim is made to the taps. As the warm water exits the system through the faucets, shower heads, appliances, fresh, cold water is the main city of the stove , where a heated applications. Typically, the heater will heat water in the house two or three times a day.

If the water is heated, expands in volume as three to four minutes depending on the percentage of the initial and final temperature. If there is no demand for hot water, the expanded volume of water has nowhere to go. Since water is practically incompressible, the water can not be extended to meet the rigid tubes, through which they travel, and therefore acts as a hydraulic ram, which will increase the pressure on potentially dangerous levels.

Open Radiant Heating Systems

The day of the valve, the expanded water to go to one place … back City on the Main, mix a large quantity of cold water, where it was located easily. At that time, kickspace heaters, “open” systems, because we are “open” in the main city w.

Double-check or check-valve is installed with or without a water meter, backflow of the effective “return” an obstacle, so the system is “closed”. Extended water does not find the way back to the city on the Main, so at the time of recovery boilers, hot water if you do not pull, the more water, the pressure increase, set up the heater, safety valve, generally 150 psi, open and warm water flows in the channel through the pressure relief valve.

The first signs of a thermal expansion problem is a call to a customer, angry that the pressure relief valve hot water continuously pouring hot water. The potential liability to the water authority, but much more serious than the waste water from an angry customer. We are not the customer, the Water Authority, and many experts that, long before the 150 psi safety valve, pressure is dangerous to keep a regular water heater, Taco heating valves, fittings, equipment and systems supplied by … Two or three a day.

The problem:

The “good old days” before the appearance of a cross-connection control, water, which exceeds the capacity of the water heater has flowed back to the Main City, where it was easy. But today, in return, water meters of the valve, and / or pressure
Without a bypass pressure relief valve is installed, the water covers the water heater, not return
supply to the city. This is now a closed system, and the expanded water has no place to go.
Since the water is not compressible, a rapid and dangerous rise in pressure generated in the boiler and piping system, similar to the hydraulic ram.
The setting is a safety valve is rapidly reached and the valve opens, water loss from the kettle.

The safety valve once or twice a day, which is not only economical, but also dangerous.
The T & P valve is designed for emergency control, not a plant, and this steady
Operation may cause premature due to the fact that the valve.
What most people do not realize that dangerous conditions may be well before the expansion of the pressure relief valve operates. Internal pressure in the middle of a recurring crash recovery periods in a flue gas heater, which is dangerous to the presence of deadly carbon monoxide, or even a boiler explosion.

The solution:

The best solution for the thermal expansion is the pressure to establish a normal and safe operation of control and well below the emergency setting is a safety valve. This is achieved by
makes it possible to install an expansion tank, thermal expansion is shown, but not dangerous
Pressure increase.

S extension to the scope of the doctrine of a closed compressible air cushion that acts as thermal expansion will be compressed into the room, and store the extra water added.
When the hot water system that uses pressurized air cushion forces hot water back to the system use … no waste.

How dangerous is the risk of uncontrolled thermal expansion?

It demonstrates that the thermal expansion, uncontrolled and uncontrollable, ruptured pipes and fittings, valves, blow, O-ring seals and valves, floating, or even drastically reduce the life of the heater as well. We have seen gas-fired boiler service center collapsed chimneys seen. Think of the liability for carbon monoxide poisoning, fires started by flames homes Roll-out, or the catastrophic explosion geysers.

Water heater manufacturers recognize the liability. Most large manufacturers warn customers stove when the stove is installed in a home with a backflow protection and the protected
no expansion pressure can be dangerous pressures arise to
Endanger life and property. In fact, a major manufacturer pointed out that, when installed in a house
and without an approved backflow thermal expansion pressure, life expectancy is only 6-13 months of the new water heater warranty is automatically void.

Solution of the thermal expansion

What is the solution for the expansion?
If the water authority does not do anything in order to adequately control the thermal expansion of the homeowner or service ignorant people to go their own way. After the exchange of continuous pressure relief valve in two or three times to believe, wrongly, that the safety valve is defective, it can try to bind the obvious solution for the pressure drain valve, the lever down, or completely removed. This is not a good solution, and actually increases the problem.

While the obvious fact that the system (ie, the dripping water), his only asset was removed from the shelter, and water heating is a potential bomb was stopped at the basement or utility room.

The other “solution” is that people can install a second valve in turn wired to a constant flow, relieve pressure on the lower level to protect the system from thermal expansion
Pressure. Again, this is not a good solution. The pressure relief valve is a safety device, and ideally never
be served. Common sense dictates, and water conservation, proper control of the thermal expansion does not lead to a continued decline in hot water.

Imagine the effect of 0.59 and a half liters of water daily for losses in municipal pipeline
200,000 homes.
The obvious solution to the thermal expansion pressure on the way to the plumbing and heating industry
operating successfully in hot water heating systems for 100 years … a pre-pressure diaphragm tank.

Pre-print Thermal expansion tank

The joint design of the thermal expansion tank hot water system includes a stop in a closed air space, forward pressure on the supply pressure in the boiler and separate water system in a bend of the membrane, installed in the air absorption and loss of the water system. The water contains a separate page with a rigid polypropylene liner, is connected to the tank walls from corrosion by
aggressive water. Polypropylene has been successfully used in water system pressure tank liners for 40 years.

The thermal expansion tank is installed in the supply line to the radiator. As already under pressure
Weight to ensure the water does not enter the tank. Since the water is heated, the expanded water is forced
The tank, the diaphragm down, bent, compressed in a closed air-cushion. Since the air
Cushion compresses, the pressure rises. When the hot water in the container get the system back to
used. The water is not wasted, and there is no waste of heat energy.

The knowledge, the connection to increase the amount of air pressure, the tank can be sized to increase the pressure to limit the safe edge. Recovery is complete, the final print will be clear at
Under the safety valve setting. For example, an F-4-liter bottle of thermal expansion and the standard fee prе be safely treated as thermal expansion of the water volume of 120 l of 160 degrees
(71 ° C), the domestic water temperature, up to 80 psi inlet pressure.
The expansion tank is a low-cost, easy to install controls that the solution to the problems of thermal expansion, and it provides drinking water service apartment is equipped with valves tools.

All codes are national borders, including the Uniform Plumbing Code (1991 edition), has now approved the installation requirements for thermal expansion control device.

Each local water authorities and water companies charge
Implementation and enforcement of codes, the valves, to carry out the local regulations
The text of the L-mode code for mandatory requirements of the expansion of prevention. This
must be taken to protect the water users’ lives and property, and just as important to the setting of the water supply may be liable for damage caused uncontrolled expansion.

Air-free water for radiant heating system by Spirovent

The air separator is a special tube made of copper fitted with woven copper wires soldered to the side wall of the tube. It has been designed to separate air from water. In order to achieve this objective, the mixture of air and water is made to pass through the system in reduced velocity to separate the air. It effectively gets separated from water and binds with the medium. Free and trapped air is absorbed, dissolved and finally eliminated. The smallest micro bubble is also allowed to rise. As water passes through the tube, the velocity gets reduced and allows the separation of air. It eliminates the dirt in water through a side valve. Prior to the introduction of this system, many methods such as the centrifugal air separator were tried but could not produce the desired results.

The air eliminator comes in varied configurations to meet the requirements of different heating or cooling systems. The noise created by the systems would be cut down because of the air removal. It would therefore be feasible to go for such superior quality Spirovent systems that can significantly enable one to achieve the desired results.

If your house is being built with a radiant floor heating system, it makes sense to add snow and ice melting duties to the heating system. Many home-buyers are ready to pay more if they don’t have to shovel snow again. And it’s a safety issue. Radiant snow melt system can reduce ice and snow built-up, and prevent slip-and-fall accidents.

A typical installation of radiant snow melt system is not that much complicated. Basic heat loops are installed as in a radiant floor heating system. There is, of course, a need for heat source, valves, controls, heat exchanger, and so forth. The heat source for the radiant snow melt system can be the same heat pump or boiler that supplies heated water to the interior heating system.

There are a few reasons why a brazed plate heat exchanger should be used in a radiant snow melting system. First, since the antifreeze heating fluid is used on a snow melt side, heat exchangers should be used to separate the boiler side heated water from the antifreeze fluid.

Secondly, many boilers don’t work well with a low-temperature water, especially in a heat-up stage, when lots of condensation builds up. In addition, a standard boiler can be producing supply water that is too hot for the snow melting system.

Cracking is also a concern when radiant floor heating cables for snow removal system is installed in a walkway or drive-way. When a concrete slab or asphalt is heated too quickly or to a high temperature around the tube, cracking is a possibility.

For all these reasons, a brazed plate heat exchanger is highly desirable in a design for radiant snow melting system.

To warm floors in interest Pipe Polybutylene (PB). Polybutylene – elastic material and sufficient heat resistance. RV-pipes are supplied in coils and easily fit into the design of the floor, taking any complex configuration.

The problem of high thermal deformation of polymer pipes, as well as the possibility of diffusion of oxygen through the wall of plastic pipe has created a new type of pipes – metal-polymer composite pipes. There are two types of metal-pipe. In one case, the aluminum tube is in the middle of the pipe section of PEX and all layers are connected by adhesive layers. In another case, aluminum shell is close to the outer surface, and it protects only a thin layer of polymer.

Metal-pipes are five times lower coefficient of thermal expansion and good protection against oxygen diffusion. In addition, metal pipes are well bent and hold the shape imparted to them. Of those pipes are well assembled complicated system configuration, various liner, such as heating appliances. Metal-tube effective in open wiring, especially for connecting various devices (radiators, water heaters, etc.).

A controversial point in the evaluation of metal-pipe is a monolithic communications polymer – aluminum. Radically, in our view, it is solved only in pipes Fuzioterm – headquarters “with perforations in aluminum foil.

Another variant of the pipe from the diffusion of oxygen – coating the surface of the pipe varnish film based on polyvinyl alcohol. The disadvantage of this solution is the low resistance of the film scratching and shock.

Heating systems using heat-radiating films
PRODUCTION: The Producers from France.
APPLICATION: Electric radiant floor heating cables and floor heating mats in homes, offices, in the workplace. In large shops they can not heat the whole building, but only jobs.
Parameters: the optimum temperature 18 degrees Celsius, the optimum temperature of objects 20 degrees Celsius, the maximum temperature at the surface of the film 40 degrees Celsius, the specific power of 125-135 W / sq. meter.
Materials and equipment: in the designs of floors and ceilings in the stretch as the heating element using heat-radiating plastic film width of 600 mm and a length of 50 meters. When installing it can be cut.
Thin film (less than 1 mm thick) polyester. Inside it are across the conductive graphite strip width from 5 to 25 millimeters. Both ends of each strip are connected with copper conductors, located also in the thickness of the film perpendicular to the graphite one along the edges. To connect to the mains supply of 220 volts to connect with the heating mats. The “ceiling” version of the distance from the edge of the film to the veins wider “cold” fields are used for fastening.
For ceilings use the heating plates of length 600 and 1200 mm, width 600 mm. They consist of screen-lens (which is also the finishing layer), heat-radiating film and insulation material (mineral wool or glass wool). The thickness of the panels in the middle reaches 50 mm. Incidentally, the film heat-radiating panels is slightly different from the roll. It has not two, but one cable, and equipped with the usual flash.
An integral part of systems is the thermostat. It is equipped with an electronic scoreboard, which shows the air temperature, and thermal sensor, which measures the temperature of this.
If necessary, connect the device differential protection. It stops the current in case of damage.
INSTALLATION SYSTEM FOR FLOOR: After installing the thermostat taken for the device of the electric heating systems. When the equipment floor first floor on a concrete foundation laid hard insulating material thickness of about 30 millimeters. If the underlying premise is warm, would be enough of a thin insulating layer of polyester (PES), the thickness of 4-8 millimeters, which is both heat-shield.
Roll film is cut into individual elements so that they conform to the length or width of the heated area. For copper veins connected via cable and insulate the incision and contacts. Elements can be stacked in parallel, sequentially, close or move. Cables connect each of them with the basic, which are led to the thermostat.
After installation, make the big switch, and if all goes well, make concrete screed thickness of 10-30 mm.
Installation of the system for tension ceilings: here, too, used diced elements with plastic film. But the film is the length of a broader “cold” field, intended for attachment. Fields are attached straps to steering lag set in increments corresponding to the width of the film. The minimum distance between the film and ceiling material shall be 50 mm. This is done to avoid deflection finishing on the heat strain.
The connection of the heating system with thermostat too by using the heating mat. By the way, to one thermostat can simultaneously connect two heating systems – and located in the floor construction, and the ceiling.
Installation of the system for suspended ceilings: in cells bearing structure such as Armstrong ceiling heating panels are placed alternately with normal (usually in a checkerboard pattern). This mode allows you to leave enough space for the installation of lighting.
Plug panels are connected to an outlet of heating mats in the ceiling space and connected with all of the Honeywell prestige thermostat.
MAINTENANCE: In the operating position by turning the system is the thermostat. Also set and temperature. Note that position things too close to the heat source is undesirable. In case of accidental mechanical damage to heat-radiating the film location of damage can simply be insulated. If damaged in one of the graphite bands, all the rest will work. But if a nail gets hammered copper conductor, it will probably need to change the whole element.

Solar S3. From Italy with love

New Italian Radiators Solar S3 about 17% cheaper than the standard line. But it is not only their dignity!

The main difference between these models is that now the side “petals” was 3 (previously – 4) and heat transfer (at dT = 70 degrees) decreased by 16.5 W (179.5 W, Standard Series – 196 watts). Thus, Solar S3 lost in heat transfer from 8,5%, and the price 17%!
Steel radiators PURMO. We care about the heating!

Radiators PURMO installed for heating homes, offices, service and other facilities. Their main advantages:

* 10-year warranty;

Radiant heating systems have come like a blessing from the God for the people who live in extremely cold countries and these systems have been made possible only with the help of the pipe. PEX Tubing has a very important role to play in the making of these radiant heating systems. PEX are the cross linked polyethylene molecules which have given a wonder material to the plumbing world. In today’s time there are more than seventy percent homes in the world which use radiant heating systems over any other type of heating systems.  The PEX Tubing based heating systems are also being used in the commercial building along with residential areas.

The radiant heating systems work on the basic principle of running the heating systems under the floor. Such heating systems can only be successful if the quality of the pipes being used under the floor is good. This is the main reason that for such heating systems only the PEX Tubing is used. The PEX Tubing is a trustworthy piping system. The PEX pipes are long lasting and have a capacity to take in extreme heat also. There are many other type of radiant heating systems but there is none that is as sophisticated as the ones which use PEX pipes under them.  The residents who have radiant heating systems installed at their homes spend their life at very comfortable temperatures.

There are many different types of PEX pipes in the market and it is very important to pick up the best possible option. The better the quality of the pipes the better is the heating process. As the pipes run under the floor, it is obvious that these pipes are then covered by concrete after the installation process. The copper pipes in such conditions can get easily corroded when placed in concrete but the PEX Tubing do not get rusted or corroded.

There are many other reasons for which the PEX Tubing is preferred over any other type of tubing when the pipes are to be used in the radiant heating system. The PEX pipes are more cost efficient and also energy efficient. These pipes help save on a lot of energy. Using the radiant heat systems also decreases the consumption of fuel by almost fifteen to twenty percent.  The radiant heating systems are not only comfortable but also very safe. These systems also keep the homes free of dust, bacteria, cold spots and other air contaminations.

Calculation of heating systems for private houses

The effectiveness and reliability of the heating system at home depends on its correct calculation. Calculation of the heating system is carried out so as to achieve to ensure optimum temperature in the room.
The heating boiler and the calculation of its power

Very often in private homes and cottages of the role of the generator of heat in the heating system hot water heating boiler serves, which is known to be electric, liquid fuel, solid fuel, gas or a combination.

The effect of the actions of an autonomous heating system is directly related to power your chosen boiler. If it is not enough power to heat your home, it would not achieve a comfortable temperature in the house during the cold season. If the power unit, by contrast, is redundant, you can “fly into a lot of money” payment for fuel consumption.

Specialist engineers note that the main criteria that should be used when calculating the capacity of the boiler, it

* Area of heated space (S);
* Specific capacity of the boiler room on 10m3, which is installed with the amendments to the climatic conditions of the region (W sp.).

There are generally accepted values of specific capacities for climate zones:

* For the suburbs – W ud. = 1,2 – 1,5 kW;
* For the Northern Areas – W ud. = 1,5 – 2,0 kW;
* For the southern regions – W ud. = 0,7 – 0,9 KW.

Calculate boiler output (W cat) is as follows: W cat. = S W ud. / 10. Often, for convenience, use the average value of W ud. Equal to one. On this basis, decided to choose the power of the boiler at the rate of 10 kW to 100 m 2 of heated space.

Example: 1. The area of heated space S = 100 m3; specific power (W sp.) For the Chicago Region = 1,2 kW; makes the calculation for the above formula and obtain: W cat. = 100 1,2 / 10 = 12 kW.

It should be noted that the settlement terms on which the selected radiator, observed during heating of buildings is not always the case. During the heating season change the ambient temperature, the buildings affected by episodic wind and solar radiation, heat in rooms uneven. Therefore, to maintain the thermal regime of the premises at a given level should be in operation to regulate heat transfer and heating devices. Operational management of the heat flux heaters can be both qualitative and quantitative.

Quality management by changing the temperature of the coolant supplied to the heating system. Such regulation of the place of implementation can be central, conducted on the thermal power station, and local, performed in a thermal point of the building. In the housing construction is carried out as a group in the regulation of TSC.

Quantitative regulation of heat radiators by varying the amount of coolant supplied to the system or device. At the venue it can be not only central and local, but also the individual, ie, performed at each device.

Operational management of heat transfer devices can be automated. Local auto regulation in the heat point of the building are usually carried out, focusing on changing outdoor temperature. Individual automatic control of heat transfer device is rejecting an air temperature in the room from a given level (regulation “by the deviation”).

Radiant PEX heating is a floor heating system in which this particular tubing is laid under the floor and aluminum sheet is spread over it. Through this tubing, heated water is passed to heat the floor and make the room warm and cozy during the freezing temperatures. It is highly cost effective as the PEX tubing is made up of long lasting materials with exceptional durability that can endure high temperatures. There is no loss of heat thereby reducing the water reheating bill. Radiant PEX heating is a healthier way to heat up the rooms as it does not affect the air quality. People with allergies suffer a lot when the air in the room is heated as the air may circulate particles of allergies. For new born and kids, it is the most viable option.

Radiant PEX heating is highly preferred as it is cost effective, it heats uniformly, and is very easy to install. This tubing has no scaling or corrosion problems so frequent maintenance is not required, and no overhead costs are incurred. This tubing does not develop pinholes over a period of time and the installation time is also less. PEX tubing is lot cheaper and has a record of high performance.

Heating and related problems.

Heat the floor rather serious problem in our days among modern consumers is a device heating. If rural residents and owners of country houses and wells range of possible systems is quite wide, for residents of an urban apartment, he is insignificant and the poor.

Typically, the onset of autumn in our climate zone cooling comes early. As a result, the street and the apartment is cold, and heating yet. The same applies to the spring when the rapidly advancing warm days, heating turned off, but after a short period of time on the street again, it gets cold. Consequently, your apartment does not have time to warm up and as a result – again, no heating, and the apartment was still cold.

What to do in this situation, because all urban residents are directly dependent on the central heating. Why someone has to determine whether or not you cold? In my opinion, this is not very fair. Moreover 80 percent of people suffer from a fall during spring colds for this reason.
Floor heating, as solutions to the problems of heating.

Floor heating According to experts, the best solution to this problem is the device underfloor heating. Yes, you heard right, it is the floor. Floor heating system, usually refers to low-temperature systems. The principle of it is simple. It is that as a source of heat distribution appears very surface of the floor.

It should immediately make some additions. Is installing floor heating system itself is strictly prohibited. The only exception is that if you have specialized education in this field. However, despite this fact, and certainly better to turn to qualified professionals who specialize in this type of activity, which means that not only have the necessary knowledge and practical skills.

Typically, the system of floor and central heating can be used the same sources of heat, but the principle is significantly different from each other. In particular it concerns methods of heat distribution.
Properties and advantages of underfloor heating.
