Air to air heat pumps in a typical Indiana winter do a great job curbing utility costs. With the Trane high efficient heat pumps, substantial savings may be achieved when matched with an air handler or a gas furnace. Heat pumps don’t use the same standards of efficiency as gas furnaces (AFUE annualized fuel usage efficiency), but use what is called HSPF (Heating Season Performance Factor). This takes many factors into account, but the bottom line is how many BTUs of heat are produced vs. how fast is the electrical meter spinning.
Typical Indiana winters put us at an average temperature of 25 to 35 degrees. When temperatures fall below this, the heat pump calls for back-up heat or auxiliary heat. This can be in the form of electric heat or the gas furnace mentioned above. When paired with a gas furnace, the heat pump offers optimum savings.
How do Heat Pumps work?
We’ve all felt the heat coming off of an outdoor air conditioner unit on a warm summer’s day. This is the heat that is being transferred from inside the home to the outdoors. An air-to-air heat pump has a reversing mechanism that changes the flow of Freon thereby transferring heat from the outdoors to inside your home.
