Taco Mixing Valves & Taco Zone Valves

When choosing a radiant heating Tankless water heater or other radiant heating units, we first pay attention to price and quality consumer purchased the unit: it should be simple and easy to use, reliable, aesthetic, etc. But later, paying for fuel, we are convinced that the most important characteristic of any toplivoszhigayuschego device is its cost, ie, the efficiency ratio (CAP).

The fact that not all the energy contained in the fuel consumed for hot water (hot water Tankless water heaters) and steam (in steam Taco Zone Valves), and some of it is lost in the transition of the chemical energy of fossil fuels to heat. The ratio of useful heat, ie you used in the form of hot water, warm air, etc., to the expended, ie, the energy that was contained in your pre-paid fuel - natural gas, diesel or solid fuel briquettes, - this is the efficiency of the device.

Amount spent by the heat is always greater than the number of useful heat, so the efficiency is always less than 1,0 - or less than 100%, if we assume that Qzatrach. = 100%. However, recently there have been so-called condensing Tankless water heaters, the efficiency of which can reach 102-108%. Below we describe the little trick that allows you to obtain such a high efficiency.
