Age is an important factor, as well as regular maintenance.
Maintenance should be documented, for example through a maintenance contract or annual invoices. The chimney sweep must also record their work, which a homeowner usually keeps on file.
Additionally, if there is no energy performance certificate available, I would ask for the last three utility bills showing consumption.
If the system is located in the basement, the hot water pipes should be well insulated.
I’m sharing these tips from my experience as a former used house buyer and seller.

Starting in 2015, the Energy Saving Ordinance 2014 requires the mandatory replacement or renewal of all heating systems installed before January 1, 1985. From that point onward, heating systems that have reached an operational age of 30 years must be replaced. Within these 30 years, measures are necessary if they are requested by the chimney sweep and/or the heating technician due to safety concerns, such as the risk of carbon monoxide leakage.
However, regardless of any obligation to renew or replace, it is worth considering whether an upgrade should be carried out earlier due to potential savings in heating energy. Such savings not only reduce costs but also lead to a reduction in carbon dioxide emissions.
Depending on the age of the system and any refurbishment work carried out on the building over time, which may have caused the system to be oversized, significant savings can be achieved, allowing payback periods of just a few years.
Aside from simply replacing the system with a smaller unit that can adjust its output to meet demand through modulation, there is also the option—depending on the initial conditions—of installing a gas-powered micro combined heat and power (micro-CHP) unit. This can cover not only the heat demand but also the base load for electricity. More information about micro-CHP can be found on the “ZukunftHaus” page of the DENA.
In general, these measures are eligible for funding. The BAFA and KfW programs offer both grants and low-interest loans. Further information is also available on the pages mentioned above.
Best regards, Erik
