Heat pumps have become the cooling and heating device of choice for many homeowners, whether they are remodeling for energy efficiency or buying a new home. These devices use ambient heat from one of four sources to heat or cool your home. However, deciding what type of unit to install can be tricky. Thankfully, there are only three basic factors you need to consider.
Picking the Right Heat Source
There are four primary heat sources for a heat pump, and choosing one determines how the pump is installed. The easiest installation comes from a pump that uses the ambient air as its heat source. The other three sources involve drilling or digging and use subterranean heat sources.
Drilling down to the bedrock gives a very stable source of heat and does not require a large footprint. If there is a layer of underground water, that can be tapped instead. The last method involves laying the heat line a meter below the surface of your property. This method is the most invasive and requires digging up the entire area.
Choosing the Correct Size
When choosing the correct size, two salient features must be kept in mind. First, the unit must be able to heat your home throughout the year, even on the coldest days. A good heat pump should be able to heat effectively even when the air temperature is significantly below zero.
Secondly, it must do so in a manner that is more economical than other methods of heating. In general, the larger the pump, the lower the future running costs because of its overall efficiency. However, larger pumps have a higher initial investment. This means that a balance has to be struck between the size and future operating costs.
Comparing Competing Units
Once the energy source and size have been determined, you should have your choices narrowed down to two or three possible units. Identifying which of those three you want can be difficult, but looking at the options is key. If you live in an area that is going to require cooling, you will want a heat pump that has a compressor so that it can act as a central air conditioner as well. Another key factor is the efficiency of the unit, or the COP. This is a ratio of the output compared to the input. A COP of 2, for example, means that the unit will put out twice as much heat energy as it takes to run it.
Heat pumps are an excellent way to save money for any homeowner, but choosing the right model can be hard. With the willingness to shop around and do research, you will find that the time you put into finding it is energy well spent.
