A heat pump is one of the most efficient heating and cooling systems you can have installed in your home. It does not use electricity to create heat , rather it moves heat via a refrigeration compressor which is a lot more efficient. It absorbs warmth from the atmosphere or ground, multiplies it and then transfers this heat to your underfloor heating installation.
Heat pumps can produce up to four times the amount of heat energy compared to the amount of electricity used.
Underfloor heating systems combined with heat pumps offer a very economical and comfortable heating solution for new homes and renovation projects.
Ground source heat pumps
Ground source heat pumps collect energy stored in the earth and can use it to heat water in a cylinder for distribution to heating systems. This is one of the most advanced technologies available for home heating and hot water. Because the earth ‘stores’ low temperature heat energy it is an extremely reliable and constant energy source, it creates no harmful emissions and uses a very small amount of electricity.
Geothermal or ground source heat pumps have been around for many years in various forms but many people in Portugal are still not aware of them or would consider them a viable option for heating their homes when considering a new heating system. Ground source heat pumps have begun to gain popularity in the rest of Europe.
Installing Ground Source Heat Pumps
The installation of a Ground Source heat pump involves the installing of loop collectors underground in your garden (if your garden is particularly small the collectors can be placed vertically as well as horizontally), these then take heat from the ground and store it ready to be used to heat your home.
Another advantage of ground source heat pump systems is they are very quiet when running.
Air source heat pumps
An air source heat pump makes heating your home and hot water much cheaper. You can reduce your heating costs by up to 65%, although the exact figure depends on several factors such as where you live, the size of your house and whether or not you use the cooling function. Your initial investment is relatively low since an air/ water heat pump, unlike a ground source heat pump, does not require any geothermal drilling. The efficiency of the new heat pumps (they have a specially high operating range) positively impacts on the speed with which you recover your investment. With energy prices continually rising, you’re unlikely to regret your decision. In fact, you’ll start enjoying savings from the first month.
The second reason for choosing an air/water heat pump is that it is so environmentally friendly. By merely upgrading naturally occurring energy from the air outside to heat your home and hot water, it leads to much lower CO2 emissions than any traditional fossil fuel based heating system.
