The word PEX tubing has become a common word with people who are into plumbing. It is polythene which is cross- linked and an acronym is used to give it an easier name PEX. It can be molded into tubes that can be used for various purposes. This type of tubing is one of the long lasting materials that are in use for many purposes. The material is chlorine resistant so drinking water can safely be transported in it. PEX tubing has become an alternative to PVC and CPVC pipes in many places. The tubing is used in hydronic radiant heat tubing, in the insulation of high tension electric cables, household water pipe lines etc. Their size may vary from 1/4 inch to 4 inches. The sizes which are predominantly used are 1”, ¾” and ½”.

PEX tubing can be used for off shore natural gas, oil transportation; chemical slurry and sewage can also be transported. The tubing is widely being used for various domestic purposes as well. To use PEX, lesser fittings are required to fit a pipeline. No elbows are needed to turn it at the corners. The flexibility of this tubing system is unbelievable. As PEX tubing can be fixed with lesser fittings, the chances of leakage are minimized. It also has a lesser chance of bursting as it is highly flexible and expandable. As the water freezes or expands due to cold or heat, it can effectively withstand such extreme temperatures. While installing, care should be taken to use the insulating material locally prescribed. PEX tubing can be snapped into any connector and used with ease. There is no need to screw the pipe; it just has to be pushed to fit in.

PEX radiant heating tubing is being used in countries where the temperatures are pretty low; to keep the floors warm. PEX radiant heating tube is placed under the floor to keep it warm. Refrigeration warehouses and Ice rinks are also making good use of this tubing. Hydronic radiant heating systems also use this tubing as it can withstand great heat. The popularity of this tubing is because of its exceptional capacity to withstand heat or cold, its flexibility and ease in handling and non corrosive properties. PEX tubing is available in varied colors. It has become quite common to use blue for cold and red for hot water in homes or places where both hot and cold water is used.

Water-heated floors often can get by even without ties: the whole assembly is carried out in several layers of gypsum plasterboard, which forms the floor construction. With thermostatic control valve and the indoor temperature is maintained with high accuracy. Water floor – out of competition, if you want to heat large areas. If the floor area of about 1m2, here apart from the competition floor electric. The real life of warm floors – more than 50 years, PEX radiant heating systems based on them can actually save 10-15% of energy used for PEX radiant heating: it warms up we are only a layer of air in which there are people. And this economy appears more strongly than the higher elevation areas. The popularity of these radiant heating systems is constantly growing. For example, in Sweden 90% of newly built houses equipped with a PEX radiant heating system with floor PEX tubing  radiant heating, in Finland – 50%.

How to warm and dry sweet home?

Any radiant heating system – it is a complicated project, and its embodiment in the life to be trusted only to qualified professionals. As manufacturing technology and water, and electric heated floors are very similar: how to lay cables and PEX pipe (PEX Tubing) are the same. Cables require somewhat more careful handling and filling, as must be prevented air bubbles in the concrete – it can lead to overheating of the cable and internal damage. Each of these systems have their advantages and disadvantages. For example, electrical systems require no maintenance during the operation, but electricity is more expensive than other sources of heat. It is easy to manage the process of PEX radiant heating electric floor PEX radiant heating, because thermostat is placed in each room, but large areas have to put extra, sometimes not cheap electrical equipment.

Warm floor: Taco Heating Valves Tips

The main option seems simpler: the existing floor is laid fuel cells, is pouring over a thin layer (2-3 cm) cable ties. But if in the first case we have an opportunity to lay a thick layer of insulation (3-5 cm), and pour concrete over a thickness of about 5 cm, in the second case, we do not even know what is in the body of the old floor. There may lie metal beams or other structures, which will lose heat even on street walls. Therefore, if you can put a layer of insulation, the power falling on a square meter of the floor, will be small – 90-120 W/m2. A layer of insulation if not, you will have to compensate for the loss of heat excess installed capacity.

If we do a full system of PEX radiant heating, the first is thermal design, and only then – to select the necessary equipment. It is this: if the floors, electrical, then the cable  in a thick concrete screed (not less than 10-15 cm), which plays the role teploakkumulyatora. This solution is used forPEX radiant heating of offices, production areas and where there are no people at night. After all reasonably possible to heat the floor at night when electricity grid is generated in excess and it is cheap. But during the day take advantage of the warm night. The same system can be constructed on the basis of water-heated floors. But there teploakkumulyatora role will play a special capacity drive, in which the coolant is heated to maximum temperature.

If  then by means of special Taco heating valves are added to this heated coolant is circulating in the system that allows long-term use of previously accumulated heat. With direct PEX radiant heating control system continuously monitors the air temperature in the room and, if necessary, includesPEX radiant heating, regardless of time of day and the tariff.

Even more difficult the formation of convective currents that cooking zone extends almost the entire floor. The heat is rising from the lowest point of the room – the floor. Surface temperatures can fluctuate from 24 ° C to 32 ° C. The air temperature near the floor 20-27 ° C, and at the level of the head, it is 17-24 ° C. Here is shown such a wide temperature range because of underfloor equip accurate thermostats, allowing easy set the desired temperature, which is then maintained for a long time. It turns out that the most pleasant temperature will be just where we reside. Hence the heightened sense of comfort, but also lower fuel consumption or electricity. We do not want to spend extra money on PEX radiant heating do not know why!
There are two ways

So, we found that in every room in the floor laid the heater, which provides the necessary amount of heat. Heat flux, and therefore comfort, can be controlled by thermostat. In the case of water we have equality in doses of supplied hot water, and in the case of electric floor – the amount of electricity. Due to this and maintained the required temperature of the floor.

Warm floors can operate in two modes: simple comfort (or warm) or a full floor PEX radiant heating. However, this classification is usually applied to electric sex. These systems differ only in the fact that in the first case, the power per square meter of floor surface is lower than in the second case, and the only PEX radiant heating homes simply not enough. Typically, power for comfortable floor of 90-150 W/m2. Its value depends on many parameters, which fully take into account is often impossible. For example, if the premises being renovated and it arranged warm floors, then we have two options.

However, if the room is planned to install furniture or equipment that will not move, then the warm floor beneath them is not done. The design of such floors is as follows. First is dirt or concrete base, then – a layer of warmth and waterproofing. Insulation laid on top of concrete screed with fuel elements: PEX pipe of hot water PEX radiant heating or electric cables. You may ask: “Why do you complicate things, when you can just hang on the walls of the battery?”. Answers – for comfort.

The author has personally experienced something almost heavenly bliss, which provides such a system. Being in the house where the only PEX radiant heating system was heated floors, I was surprised that the air temperature in the room did not exceed 18-19 ° C. In the yard – minus 24 ° C, and a general sense – all the comforts. The house shed a soft, pleasant warmth. Arrogant cat was not to banish from the tiled floor, where the animal warmed after a walk down the street.
