I.What to Look for When Choosing a Heat Pump?
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.


When it comes to choosing a heat pump there are some things that must be taken into account such as: 
    The climate where you live.
    The type of house or building where the heat pump will be installed.
    The number of people living in the house.
    The capacity at which the heat pump will be used.

II.What to Check When Comparing Heat Pumps From Different Producers?

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. Read more about performance measures here: Air source heat pump performance.

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.
