FAQ
Brine-water heat pump
What is a brine-to-water heat pump?
A brine-to-water heat pump is often referred to as a ground source heat pump. It uses geothermal energy as a heat source.
Where is a brine-to-water heat pump used?
From a small bungalow to large industrial facilities, they can be used anywhere. Such plants are highly efficient, low-maintenance, noiseless and have low operating costs.
What does active and passive cooling mean?
With active cooling, the cooling process in the heat pump is reversed and thus the heating water is cooled. Passive cooling uses heat exchangers to exploit the temperature differences between the heat source and the heating water.
How long does a brine-to-water heat pump last?
The service life is between 20 and 25 years, depending on the load, and is relatively low-maintenance.
Are maintenance and inspections necessary?
Maintenance is not mandatory, but maintenance contracts are common in rental apartments.
Are there wear parts, when do they break?
Only the usual circulating pumps and pressure equalization vessels are subject to a certain amount of wear and tear and are likely to require replacement at some point in their life cycle, just as with any other heating system.
Is a ground source heat pump better than an air source heat pump?
One difference is the heat source: air at -10 °C is not as good a heat source as the ground, which still provides about 5 °C even at cold temperatures. On the other hand, the annual performance factor for air-source heat pumps is usually around 3, for ground-source heat pumps at least. 4,5. Another advantage of ground-source heat pumps is the significantly lower demand for refrigerants, and the internal structure of ground-source heat pumps is also much more robust.
