Home heating efficiency: optimizing heat pumps and insulation

The transition to sustainable home heating requires careful technical planning to avoid high energy costs and inefficiency. Experts emphasize that heat pumps are not limited to new builds with underfloor heating; properly insulated older homes with radiator systems can also be suitable, provided the radiators can operate effectively at lower water temperatures.

Key technical considerations include the building's thermal envelope and insulation quality. Unlike gas boilers that can compensate for poor insulation by using high water temperatures, heat pumps are most efficient at lower temperatures (typically 35–45°C). A mismatch between the heating system and the heat pump can lead to significantly higher electricity bills.

To optimize efficiency, modern solutions include smart radiator controls and digital actuators that allow for precise, room-by-room temperature management. Companies like Remeha are expanding options by investing in both split and monoblock systems to provide flexibility for different housing types, while Mapei offers guidance on avoiding common insulation mistakes during renovations.
