Why Heat Pumps?
How Does a Mini-Split Heat Pump Work?
Like your refrigerator, heat pumps use electricity to pump refrigerant and transfer heat from one space to another. When we transfer heat from within our home to the outdoors, we call it "air conditioning". Conversely, when we transfer heat from the outdoors to within the home, we call it a "heat -pump".
Heat Pumps Versus Electric Heaters
An electric heater converts electricity directly to heat, and if we assume that the heat loss is zero, the output from one kilowatt input is one kilowatt or 3,400 BTU and the EER is 3.4.
Heat pumps are more efficient than some other forms of heating because heat pumps do not actually create heat, they just move it from one place to another.
For example, the output of an efficient 10 EER heat pump is triple that of an electric heater.
Our 9RLS2 has an EER of 15.0, almost 5 times the efficiency of an electric heater.
*EER (Energy Efficiency Rating) = Rated BTU capacity divided by total KW input.
