Heat pumps


Heat pumps are an excellent option for heating and cooling your home. There are many advantages to installing a heat pump.

There are basically two types of electric-heating options. The first is electric radiant heat. Most people know this as electric baseboard heat, but it can also refer to portable plug-in heaters. Some members even have electric radiant heating components in a furnace. This type of heat is 100 percent efficient because all of the heat is applied directly to the living area. There is no loss of heat or fuel in a combustion process, as there is with an oil, gas or propane burner. You get 3,413 British Thermal Units (BTUs) of heat for 1 kilowatt hour (kWh) of electricity. Unfortunately, it takes a lot of BTUs to heat a typical home, and that can get expensive at 3,413 BTUs per 1kWh.

The second electric heating option is the heat pump. After the development of modern refrigeration, someone realized that the refrigeration process removed heat from the freezer to make it cold. The heat that was removed from the freezer got put into the kitchen. Anyone who has stood barefoot in front of the refrigerator can attest to this. This concept launched the heat pump.

A heat pump does not actually make heat, it simply moves heat through manipulation of the refrigeration process, as refrigerants can be super-heated or super cooled. You may ask how it can move heat on a cold day. There is always some heat in ambient air (the normal outside air around us). Let’s consider a freezer that is 20 degrees. If we continue to run the refrigeration equipment, we can remove more heat from the freezer until the temperature is further reduced, even down to well below zero. A central air-to-air heat pump outside your home can remove heat from the ambient air and apply that heat to your home. An advantage of this process is more efficient heating. A 300 percent efficient heat pump produces 10,239 BTUs for 1 kWh of electricity (three times the amount of heat compared to electric radiant heat). Another advantage is that by reversing the refrigerant cycle, the same unit can remove heat from your home and move it to the ambient air (air conditioning).
