Takagi TK-3 series have been favorite for all, and to meet the requirements of every individual it has launched its new Takagi TK-3-LP tankless water heater. This model uses natural gas as its fuel type and works automatically. It is one of the most powerful and flexible unit with remarkable features. Under normal conditions this model is able to replace a typical 50 gallon standard storage tank type water heater.

The Takagi TK-3 propane model has a high efficiency rate of 86% and can supply three fixtures at a single point of time. It consumes an electrical supply of 120V i.e. 60Hz which is lesser as compared to other tankless water heaters. The features that make this product distinct from others are:

  • Low activation flow rate.
  • Improved built in freeze protection.
  • PEX Hydronic and radiant heating applications in residential and small commercial spaces.
  • Easy Link capability which permit to connect up to four units with each other without the use of a controller unit.
  • It can have a vent pipe run up to 50ft with equipped 5 elbows without the use of any additional equipment.

These features make the Takagi TK-3 propane model different from other tankless heaters and make it most advantageous for usage at residences with 2-3 bathrooms and even for small commercial spaces.

Gas water heaters

In the residential water heating system, accommodation often equipped with special heat sources – well-known and long gas water heaters (boilers) DM AGW, AUGV, AOGV. All of these heaters on and off the main burner (by opening or stop the flow of gas to the burner) are carried out automatically by the thermostat.

AGV – capacious water heaters to 80 and 120 liters, the power of 7 and 29 kW at an efficiency of 81 … 83%. AOGV – is small and metal content.
AKGV – dual function apparatus destination: for space heating with heat losses to 18,5 kW, and at the same time for hot water flats.

Gas tankless water heaters

They are used in air heating systems of buildings as additional sources of heat in combination with other heating systems installations. Here the heat of combustion is transferred wholly or partially cold outside air, heated by the apparatus. In the heat transfer through the wall of efficiency ramjet, or circulating air reaches 70 … 90%. In the mixing apparatus by direct mixing of combustion products and heated air increases the efficiency up to 100%. Known direct-flow heaters relatively low power (50 kW, 70 … 2000 m3 / h at a temperature of 50 … 700 C) and more powerful (450 kW, up to 16000 m3 / h air at a temperature of 100 … 1100).

The Takagi Jr tankless water heater, manufactured by a 25 year old brand is an optimal choice for small residential apartments and homes. This tankless water heater utilizes the latest technological advancements to make the highest quality, on demand hot water heating products available in the market. They are gaining recognition as there is no storage tank to fill, there is uninterrupted supply of hot water and it comes in different models and fuel types.

The Takagi Jr tankless water heater propane model can be used for different applications of domestic hot water heating, radiant heating and hydronic heating. It is one of the most compact forms and can replace a 40 gallon standard storage tank type water heater. The fuel used in these tanks is propane with a maximum BTU rating of 140,000 BTU/h. It has almost 83% to 85% energy saving efficiency which is quite a good figure for saving huge electricity bills. The water flowing capacity of this heater is 5.8 gallons per minute. One of its distinct features is that it allows a maximum vent run up to 35ft of pipe with only 3 elbows which makes it easy to install for outdoor spaces.

This water tank is highly efficient and portable which makes its handling easy and comfortable. It can be installed by a single person only and will not occupy a large amount of wall space. With so many qualities the Takagi Jr has been able to capture a large market share and has gained momentum in small residential spaces.

Taco pump is a machine that absorbs low-potential radiant heat from the environment with a temperature of 4 – 6 degrees Celsius and above, and transmits it to the system of radiant heat supply to consumers in the form of heated water or air. Heat transfer is a working body – the refrigerant (Freon). Electricity consumed by Taco pump, is spent only on the movement of freon to the system using the compressor, just like in refrigerators. The system operates as a Tankless water heater for radiant heating and cooling as air conditioning. In winter, heat system “warm land transfers in the house. This same cycle is used to heat water. In the summer of excess heat in the house passed through a water to water heat exchangers in the opposite direction.

As a low-potential source of thermal energy for radiant heating a home can be used in the heat of natural origin (outside air, warm soil, artesian and thermal waters, the waters of rivers, lakes, seas and other natural ice-water). Taco pumps equipped with control systems and automation, which supports the specified mode of Taco pump.

Energy efficiency of  Taco pumps depends on the temperature of the source of low-grade and will be higher, the higher temperature, it will have.

* Economic efficiency of Taco pumps depends on: the temperature of low-grade source of heat;
* The cost of electricity in the region;
* The cost of thermal energy produced by using different fuels.
* Use a Taco pump instead of the traditionally used sources of thermal energy in an economically advantageous because of: there is no need to purchase, transport, storage and fuel flow of funds associated with this;
* Release of large areas, needed for the Tankless water heater rooms, driveways and storage of fuel.
