Air Water Heat Pump Floor Heating vs. Electric Underfloor Heating

With the gradual elimination of pollutive and traditional heating methods, clean energy house heating has gradually become a new choice. At present, the main new house heating methods include air source heat pump heating and electric heating. Underfloor heating with an air source heat pump is more popular. So, why is it better to use air to water floor heating than electric heating?

Next, we will give you a detailed introduction.
Firstly, let’s get a general idea of how air to water heat pump floor heating and electric underfloor heating work. Electric heating is the direct conversion of electricity into heat energy, the efficiency of which is about 85%; that is, each kilowatt hour of electric energy can generate about 850W of heat. The working principle of air source heat pumps is to use refrigerant to absorb low-grade heat from the air and compress the heat into high-grade energy for users through a small amount of electricity to drive compressor. Therefore, air source heat pumps consume less electricity. Take a LEOMON air to water heat pump as an example. Its energy efficiency ratio is as high as 4.19, that is to say, the heat generated by air source heat pumps is about 4.93 times that of electric floor heating.

Secondly, we will compare the comfort level of these two floor heating methods. Air source heat pump floor heating radiates the heat to the floor through the underfloor hot water of no less than 55℃. Its heating process will not affect the indoor winter humidity. On the contrary, electric floor heating evaporates the moisture of indoor air when heating by cable. We all know that the air is relatively dry in winter. The standard of human air humidity is 30%-60%, and the environment with a humidity index of 50%-60% is the most comfortable for human body. Therefore, in contrast, underfloor heating with an air to water heat pump can be more comfortable than electric heating.

Finally, let’s take a look at the heating costs of air source floor heating and electric floor heating. Air heating usually requires 40W of heat per square meter in one hour. For a household with a heating area of 100 square meters, the monthly electricity cost is about $76. With electric heating, a household with a heating area of 100 square meters consumes 80KW heat load every day for 8 hours. If the electricity bill is calculated at $0.11 per kilowatt hour, the daily electricity cost is about $8.8, and the monthly cost is $264.

All in all, we can see that air to water underfloor heating is a better choice than electric heating in terms of efficiency, comfort and heating cost. So in the long run, underfloor heating with an air to water heat pump is definitely more beneficial to users
