Low-cost low-temperature heating with heat pump.

Author(s) : AFJEI T.

Summary

Future low-energy dwellings have an annual heat demand of under 200 MJ/m2a yielding a 30-40% share for the hot water heating. Simulations showed that it is possible to connect the heat pump directly to the distribution system without buffer storage. Operating interruptions of two successive hours are not perceptible in the room due to the inertia of the floor heating. During periods of strong solar radiation, a slightly higher room-temperature must be accepted. The system with the highest seasonal performance factor is a brine/water heat pump with separate heat pump water heater.
