Heat pumps in the price comparison: save up to 40,000 euros!

Wiesbaden, Deutschland - Summer time is often the best time for renovations in your own home. Many owners consider whether they should switch their heating system to a heat pump. The advantages are clear: more independence from fossil fuels and a step towards climate -friendly. But there are big differences here - and the offers are often confusing.

The Federal Association of Consumer Centers warns: "The offers for heat pumps are often incomplete and difficult to understand," reports Peter Kafke. Many homeowners get the new regulations and funding opportunities of the building energy law on their nerves so that they hesitate. According to Tagesschau.de, the price differences for air-water heat pumps are enormous: the costs for installation fluctuate between 20,000 and 63,000 euros.

prices and offers in abundance

In an example from Wiesbaden, it was shown that an offer of 32,000 euros could ultimately be reduced to an installation for 18,000 euros. Such large price differences are not always justified, says the consumer advocate, and are often due to the lack of experience of some installers.

Summer is an excellent time for installation, especially in areas without a connection to a local or district heating network. Even if the installation of heat pumps is now standard in the new building, they also remain a sustainable alternative for existing buildings, according to the consumer center.

The importance of the exam

Consumers should obtain several offers and check exactly which services are included. "Almost half of the offers examined did not contain a foundation for the heat pump," warns Kafke. This means that important details such as the heating load calculation or the hydraulic comparison are often missing. Only a quarter of the offers were actually complete.

This can also be seen in the extensive range of advice from the [Consumer Center] (https:// consumer center-energieberatung.de/erneuerbaresergien/waermepumpen-iebote/). A large number of steps can be undertaken there: first select the federal state on an interactive map, then fill out a detection sheet and upload offers.

technical efficiency

Not only the prices are crucial, the efficiency of the systems also plays a major role. The annual labor number (JAZ) indicates how much heat is achieved per energy unit used. A jaz of 4 means that four kilowatt hours of heat are generated for each kilowatt hour. According to the Consumer Centers, a jaz of at least 3 is already considered efficient.

The installation and choosing the right heat source are decisive for efficiency. Devices with high jaz values are a worthwhile investment that quickly pays off. In addition, maintenance and monitoring of the operating parameters such as JAZ in the first year should urgently be integrated into the planning.

The spread of heat pumps is not only promoted by the effective technology, but also by the increasing proportion of renewable energies in the electricity mix. And even if the offers sometimes seem overwhelming, good advice is the key to success - regardless of whether by phone or video call. The owners are consistently satisfied after the consultations because the support helps them to make a well -founded decision.
