Heat pumps are considered the best alternative source of heat energy. It is not only cost-efficient but also delivers more energy than traditional fossil fuels.
The good thing about heat pumps is that they can be installed both outside and inside a house. You will also find split units in which the indoor and outdoor units are divided.
Before you decide to install a heat pump, you must know the different types available. For your convenience, we have listed the different types of heat pumps below.
- Air to air heat pumps
Air to air heat pumps is best suited for buildings with low heat requirement and a good ventilation system. These pumps are designed to utilize the waste heat coming out from the ventilation system to heat the building.
- Air to water heat pumps
Air to water heat pumps is probably the most common type of heat pump. It uses outside air to deliver heat energy inside your home. The temperature of the outside air is prone to large fluctuations. During winter, the temperature of the outside air is the lowest. This is why an air-to-water heat pump requires a powerful compressor so that it can draw in the air without any problem.
- Water-to-water heat pumps
These types of pumps require you to drill two wells so that they can utilize groundwater as a heat source. To install water in water heat pump, you will need permission from the concerned authorities. The temperature of groundwater usually stays between 8 and 12 degree Celsius all year round.
- Brine to water heat pumps
This type of heat pump is also known as a geothermal heat pump as it draws energy from the ground. With the help of a geothermal borehole heat exchanger, you can go as deep as 100 meters in the ground. The temperature underground is around 12 degree Celsius. Alternatively, you can use surface collectors. The good thing about this option is that it doesn’t require you to drill so deep.
Heat pumps are more efficient than you think. The different types of heat pumps are used in different situations.
