Heat pump in old buildings – does that really work?

Why many old building owners are skeptical

Many homeowners believe that heat pumps are only suitable for new buildings.
However, this is not always true. A heat pump can also operate efficiently in older buildings.

Important requirements

For a heat pump to function efficiently in an old building, certain
requirements are important.

These include:

• good insulation

• low flow temperatures

• suitable radiators or underfloor heating

Renovation measures improve efficiency

Energy-related renovations can significantly improve the efficiency of a heat pump.

Examples:

• Insulation of the building envelope

• Replacement of old windows

• Optimization of the heating system

Combination with photovoltaics

The combination of a heat pump and photovoltaics can significantly
reduce operating costs. Solar power can be used directly for the heat pump.
