A heat pump is one piece of machinery which you can use to both heat and cool your home. Thus, when you install a heat pump, you will save money on installation costs. If you are thinking about installing a heat pump in your home, there are two types of heat pumps worth considering. While air-source heat pumps are the less expensive option, a ground-source heat pump will provide you with better function and savings over the long-run.
An Analysis of an Air-Source Heat Pump?
An air-source heat pump will push heat into the outside air during the summer to cool your home and extract heat from the outside air during the winter to warm your home. Because a heat pump only has to move heat rather than create heat like a furnace, it can provide greater efficiency. To explain, a furnace burns a fuel to create heat, and if it could run at the ideal level, it could not extract more heat than what is available in the fuel. Thus a furnace will be at its ideal best 100% efficient, extracting 1 unit of heat for every unit of fuel it burns. An air-source heat pump can be up to 275% efficient, moving 2.75 units of heat for every unit of electricity it uses. On the other hand, the colder or hotter it is outside, the less efficient an air-source heat pump is.
An Analysis of a Ground-Source Heat Pump
A ground-source heat pump seeks to improve the function of an air-source heat pump by burying a specially designed set of coils in the ground outside your home. These coils can then tap into the consistently moderate underground temperatures. Thus, whereas an air-source unit would struggle to cool your home on the coldest winter days, a ground-source unit will have no such problem. Furthermore, ground-source heat pumps can be up to 600% efficient. Thus, they are the better value for your money. The disadvantages of a ground-source unit are that they cost more to install and require sufficient yard space to contain the coils. On the other hand, the federal government offers tax credits, which can help to offset the cost of a ground-source, or geothermal heat pump.
Your choice of heating and cooling equipment will be something you have to deal with for years to come. An air-source heat pump is not a bad choice for your home, but if you have the ability to install a ground-source model, you should do so.
