It is not always necessary to install a new heating system as optimising the existing system also allows homeowners to reduce their energy consumption. According to the VdZ, Germany’s leading association of building technology, high-efficiency pumps for heating and hot water can save up to 80 per cent of the pump’s electricity consumption - without major construction work. And this will pay off: a modern pump considerably reduces the annual energy costs depending on the electricity price and size of the heating system. Even in a single-family home, cost savings can amount to up to 100 EUR. If hydraulic balancing of the heating system is also carried out, whereby all components of the heating system are adjusted to one another, the heat consumption can be further reduced by up to ten per cent.

Optimising the system renders immediate results

Many people are not aware that outdated pumps are active even at times when they do not need to be running. This results in unnecessary consumption of electricity. Modern pumps, however, only work when they are really needed. The end of the heating season is a good time for putting the heating system to the test. Even if the heating is not on, the old hot water pump continues to work hard, consuming unnecessary amounts of electricity. Optimising the system would thus render immediate results.

If carried out now, the hydraulic balancing process would ensure even heat distribution throughout the house by the start of the next heating season. This not only reduces energy consumption but also increases living comfort. A specialist only needs a few hours to establish a hydraulic balance in the heating system of a single-family home.

Grants of 30 per cent

The Federal Ministry for Economic Affairs and Energy supports both measures - the exchange of heat pumps and the process of hydraulic balancing. In addition, it promotes the setting of the heating curve and the professional installation of pre-adjustable thermostatic valves and single-room temperature regulators - providing a grant of 30 per cent of the net costs for each.
