About Heat Pumps
Air / water heat pumps
Reversible air / water heat pumps
Water (brine) / water heat pumps
Are basically monoblock devices and evacuate energy from the water of a deep-water fountain or a geothermal heat exchanger. The available water temperature of the deep-water fountain or of a geothermal heat exchanger is usually the same, so these systems work with a high efficiency, ie. low electrical energy expenditure but high thermal energy gain. The disadvantage is the high cost-intensive installation work of the water circuit, which is usually dispensed with as a result of the long amortization period. Deep well bores are usually notifiable and are rarely allowed, also because the drainage of the waste water from the heat pump into the sewage system to the sewage treatment plant is not permissible.
Water / water heat pumps can also be reversible if they have an additional installation.
