Central Heat Pump Vs Gas Furnace

 Generally, there are two methods of heating the room during the cold winter season. They are the heat pumps and the gas furnace. However, the choice between the two solely depends on the requirement of the user. It can be quite difficult to decide between the two unless you are aware of the advantages and disadvantages of the two. But before we get into the detailed feature of gas furnace or heat pumps we need to have a basic idea as in how each of these appliances function.

 Heat pumps are unique devices. They are air conditioners which work in reverse direction to heat your homes when required. Unlike furnaces, heat pumps do not create heat, rather they move heat from one point to the other. For instance, during the summer season, heat pumps move heat from your home and deposit it outside. While during the winter heat from outside is moved inside.

Furnaces on the other hand create heat by burning natural gas. The heat is transferred to the air and in the process it gets spread within your home.

 In case of installing either the heat pump or the gas furnace, determining the proper size is important. This is because unless the appliance is properly sized it will not heat your home adequately. To determine the exact size of your appliance, it is imminent that proper load calculation is done. This can be done by employing a trained HVAC professional. A HVAC professional will be able to tell you exactly the size of the heat pump or gas furnace required for your home.

Gas furnaces are powered by natural gas which is delivered continually and is billed monthly. However, furnaces might require special utility connection besides the standard electrical connection of a home. While heat pumps are powered by electricity and do not require any special utility connection. Heat pumps have two units the indoor unit and the outdoor unit. While the furnaces are single contained units.

 Furnaces operate simply by detecting the indoor temperatures of your home and accordingly turns off and on the furnace in response to the temperature change. When the thermostat in the furnace detects that the temperature inside the home has fallen below the set temperature it turns the furnace on. As a result the heating elements produce heat and when enough heat is produced, the air handling fan blows the warm air into the duct work system and out at vents placed throughout the home. This air warms the interiors of a home and when the heat energy is expended, a return-air system brings the air back to be filtered and redistributed again.

 On the contrary, heat pumps provide heating and cooling by moving heat from one place to the other. This is done by using a liquid or a gaseous refrigerant in a series of copper pipes which are known as coils. The heat pump has coils both in the indoor unit and the outdoor unit. When the heat pump provides heat, the refrigerant in the outdoor unit is evaporated into a gaseous form which absorbs heat. The gas then moves into the indoor unit where it is condensed into a liquid form. During the condensation process it releases heat and this heat is then distributed by the air handling units.

As far as efficiency is concerned it has been observed that heat pumps are more efficient and more economical than either fuel or electricity based furnaces. However, furnaces are less expensive than the heat pumps.
