1. Heat your home with energy absorbed from the air around you.
Air to water (air source) heat pumps absorb heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -25° C. This heat can be used to heat underfloor heating systems, radiators, and fan coil in your home, and also heat domestic hot water at the same time.

2. Heat your home with energy from the ground soil or water.
Brine/ water to water heat pump (ground source) absorb heat from the ground water or soil through the dig wells or buried ground collectors. No matter where you live, the underground temperature remains relatively constant all year, even though outdoor temperatures may vary widely. This heat can be used to heat underfloor heating systems, radiators, and fan coils in your home, and also heat domestic hot water at the same time.
Ground water is especially suitable as a heat source for a heat pump because it has a constant temperature of 8 to 12 °C even in case of low outside temperatures.
Lakes and rivers also offer many options to use the heat; their temperatures are between 2 °C and 15 °C.

The ground soil is a “seasonal accumulator” of heat from the solar radiation, brine to water (geothermal) heat pumps drawing heat from the ground soil by dig trenches, boreholes with buried ground collectors.

Ground source heat pumps VS air source heat pumps
The ground source heat pump is well known by the high efficiency, high level COP. And it does not influenced by the ambient air temperature, no need defrost in winter.
Air source heat pumps are much easier and cheaper to install than ground source heat pumps, it no need to dig trenches and lay out ground collectors. So they are more suitable for a wide variety of properties from flats to detached houses.
Sirac air to water heat pumps can also offer significantly higher levels of efficiency when compared to traditional methods of heating our homes. For every 1kW of electricity fed into heat pump, you will get 3-4kW of heating energy. Besides, Sirac air to water heat pump can work efficiently all year round even if the outdoor temperature should drop to -25℃.
