Product Description
pumps. In comparison with a heating, which is purely based on electrical power, the power sourcing
is thus reduced to a quarter for the same heat production.
Comparison of the power requirement of an Aquarea heat pump with a purely electrical
heater for the same heat production

1 Conventional electrical heater
As against heating systems using fuel, the dependence on oil prices and uncertain energy imports
is thus reduced. In addition, the part of renewable energy fraction of the electric power consumed
is already around 20 % and shows a rising tendency. Other than the ambient heat, therefore, the
power used for heat pumps is also going to increasingly come from renewable energy.
In addition to the low use of electrical power, the lack of a need for stack emission measurements
also contributes towards low operating costs. The investment capital for an Aquarea heat pump is
comparatively low in comparison with the other heating systems having a natural gas connection,
chimney, oil tank or earth probes.
Optionally, the Aquarea heat pumps can also be operated with cooling function and supplemented
with a solar system and a heat recovery ventilation system. This in turn helps increase comfort and
efficiency.
Based on the environmental and energy policies of the European Union, each member state may
offer national state-promoted market incentive programmes for air/water heat pumps including
direct investment cost allowances. State-funded promotions are usually linked to certain conditions,
like e.g. minimum requirements related to the seasonal energy efficiency or annual power
consumption, which must be verifiable through heat and power meters or similar tools. A hydraulic
balance and the adjustment of the heating curve may also be required. Details are given in the
respective current European and national promotion directives.
