There are many factors to be carefully considered when choosing a heat pump and that is why we have prepared a guide below that should help you compare heat pumps manufacturers, product characteristics and help you find best-rated heat pumps. First of all, the major manufacturers are presented together with the devices they offer. Secondly, a comparison between different brands of heat pumps is made, incorporating various parameters, and the presence or absence of certain functions.
Heat pumps are an eco friendly alternative to traditional heating sources that use fossil fuels to run. There are efficiency reasons to support the choice of switching to heat pumps:
- These devices use the energy input in such a way that they produce three or four times the amount of energy provided.
- Heat pumps reduce CO2 emissions and provide the heat required without the use of auxiliary heating sources. They can be coupled with systems already in use in the house, or even with solar panels in order to reduce the amount of electricity use and boost performance.
- Another advantage is the fact that, although the initial costs can be high (especially in the case of ground source heat pumps), the investment pays back within a reasonable time frame. A clean prior analysis with in-depth considerations about the site will make the whole process a lot easier for you.
There are mainly two types of heat pumps:
The main difference between them is where they take the heat from. Air source heat pumps extract heat from external air even at low temperatures since there is always some heat, even when it is cold. Ground source or geothermal heat pumps use the heat that is stored in the ground and collected during warm seasons to activate the process instead.
The cycle is very similar for both types of heat pumps: the heat extracted from either the air or the ground is working together with a liquid refrigerant that is then passed through a compressor that raises its temperature. A condenser is used to make the gas turn into liquid again. During this process, some heat is released and it is transferred either to the radiators to heat the interiors or to heat the water for domestic use.
Air source heat pumps are available in different sizes, with outdoor units designed to emit as little noise as possible. They usually do not require a lot of space since many companies produce models that can easily fit under a standard window.
In order to install ground source heat pumps, there are a lot of variations. You usually need a lot of space for horizontal systems, since pipe systems need to be placed. However, in the case that there is not much space available, it is possible to go for a vertical system. A borehole will be drilled vertically into the ground where the pipes and ducts will be lowered into afterwards.
As pointed out before, heat pumps are very efficient devices that use electricity in an effective way. In quantitative terms, the heat pumps’ COP ranges from 3 to 4 (depending on the models). This means that with one unit of electricity, 3-4 units of heat are produced, while traditional boilers have a COP of 1 (one unit of heat from one unit of electricity).
- Wireless control. You might consider investing in wireless control if you are often abroad or if you are not at home for most of the day. It will be a convenient way to control your device and to switch it on and off when needed, even if you are not at home. Especially when it is cold outside, it takes time for your house to warm up. Using this system, you can make sure that your home will reach the desired temperature by the time you come back.
- Get a guarantee. Make sure you receive a guarantee that covers for problems that could occur in the first years of life of this device.
- Select the Kw power. It is pivotal to choose the power that serves your needs, and the amount of money you are willing to invest. While a low wattage would not provide the heat needed and would put the heat pump under strain, a way too powerful heat pump is not effective, either. It would lead to heat dispersion and would not reach the expected savings.
- Calculate the space. As a rule of thumb, for every square meter of the house you need heated, you need in between 1 to 3 square meters of pipes.
You should be aware of the characteristics that each product has, as they predefine the performance.
- Scroll compressor. Scroll compressors adjust their speed according to the desired heat level. This implies energy saving and longer heat conservation.
- TWS technology. This is a technology that allows to heat a large tank of water faster than a traditional heat pump, saving on costs at the same time.
- COP value. The Coefficient of Performance measures a heat pump's efficiency, since the value refers to the units of heat produced with one Kw of electricity. For example if the value is 3, it means that for every KW, 3 units of heat are produced.
- Match with solar cells. The possibility to couple heat pumps with solar cells is a convenient option as it enables you to experience further savings. However, not all systems are suitable.
- Cooling option. Another function that is not offered by all manufacturers is the possibility to invert the cycle during the summer and make the heat pump work as a central air conditioner. These systems may be more expensive than the traditional ones, but it is important to keep in mind that the former ones include two devices in one, and it might be less expensive than installing them separately.
