Acquisition costs of gas heating, energy-saving heat supply

Hello everyone.

We are about to buy a house. The gas heating system, like the house, is from 1988. It works, but the question arises whether there is a "better / energy-saving" heating system.

Now to my questions: What are the acquisition costs of a new gas heating system? On the internet I only find statements "4,000 - 5,000 €". Shouldn't one rather expect 10,000 €? Unfortunately, I am not familiar with this...

Can someone help me?

Thanks in advance!!!

Hello,

..We are about to buy a house. The gas heating system, like the house, is from 1988. It works, but the question arises whether there is not a "better / energy-saving" heating system

Modern gas condensing boilers are naturally more efficient due to the condensation heat recovery. However, the overall system concept (heating surfaces, hydraulics, components, domestic hot water preparation) is also essential. If everything does not harmonize sensibly, the benefit of modern technology is usually disappointing and does not justify the investment cost. Important for selection are the heating load as well as the lower modulation limit. The main energy consumption results from the energetic building status, climate location, and user behavior. Alternatively, other heat generators, e.g. air heat pumps, could also be considered, although the investment costs and the requirements for certain framework conditions are higher here.

It is very sensible to consult an independent expert here, but not the heating installer of a new system — older systems often turn out to be money pits.
By the way, request an Energy Saving Ordinance demand certificate for the building! Although this is not suitable for heating dimensioning, it provides insights into the primary energetic overall condition.

..Now to my questions: What are the acquisition costs of a new gas heating system? On the internet, I only find statements like "4,000 - 5,000 €". Wouldn't one have to rather assume 10,000 €? Unfortunately, I am not familiar with this...

Almost any value is possible here since no one knows the condition of the overall system. Good gas condensing boilers in the single-family house sector can already be obtained for around 3,000 € including installation. However, if additional and considerable adjustments to the system become necessary, 10,000 € will certainly be reached.

Best regards.

Hello Winkli,

in the course of purchasing a house, definitely ask for an energy certificate as mentioned by €uro. Maybe there is also a demand certificate that provides a good picture of the energetic condition of the property.
22 years for a heating system is certainly not exactly little, so a system replacement makes sense both for savings reasons and for supply security reasons.

The pure system replacement can be realized for the relatively low 4,000-5,000 € compared to the possible savings effect. A modernization pays off after just 4.8 years.
