Product Description

1.     General

HTW-21RT digital thermal actuator fits for radiator heater for room heating system. This digital thermostat valve has several mode selectable such as PRG programmable mode, manual mode, holiday mode, comfortable mode, energy saving mode. Compared with heat pump heating and electric boiler, which investment is more economical? Which one to choose? Clean heating is imperative, but because of the low initial investment when purchasing electric boilers, many users are eager for it. Take a building with a general structure as an example, if the heating load is 80w per square meter (recommended value for coal-to-electricity conversion), the total heating load is 1000㎡×80w/㎡=80KW; the commercial electricity price is calculated at 1 yuan/kWh; For 120 days. A total heat load of 80kW requires an electric boiler of 80kW. Throughout the heating season, the energy efficiency value of the air source heat pump is calculated as 2.5 times that of the electric boiler, and the power of the air source heat pump host is 32KW (80KW÷2.5=32KW), which is almost a 40P host.
