Hello everyone,
I received a house as a “gift” last spring, meaning I have been the owner since 2018.
The house is equipped with a gas heating system. The gas boiler is a Vaillant VKS 23/1E (natural gas) from 1990. Annual maintenance has been carried out every year so far, and the measurements are all within the correct range. The local chimney sweep also did not find any defects.
Is it required to replace this boiler after 30 years, even if all the values remain perfect and no major repairs have been necessary so far?

KS 23/1 E
Manufacturer:
Vaillant Deutschland GmbH & Co. KG
Year of manufacture:
1990
Nominal output:
23 kW (31,000 BTU/h)
Fuel:
Gas
Boiler category:
Low-temperature boiler
Boiler type:
Atmospheric gas boiler
Pilot flame:
No
Efficiency value:
73 %
Efficiency class:
D
Labeling from (exact regulation see §16 and §17 EnVKG):
By authorized persons (e.g., heating installers, chimney sweeps, energy consultants): 2017
By obligated persons (district chimney sweeps): 2017
There is no mention of a mandatory replacement under §10 of the Energy Saving Ordinance.
In §10 of the Energy Saving Ordinance it states:
(1) Owners of buildings are not allowed to operate boilers fueled by liquid or gaseous fuels that were installed or set up before October 1, 1978. Owners of buildings are not allowed to operate boilers fueled by liquid or gaseous fuels installed or set up before January 1, 1985, starting from 2015. Owners of buildings are not allowed to operate boilers fueled by liquid or gaseous fuels installed or set up after January 1, 1985, after 30 years. Sentences 1 to 3 do not apply if the existing boilers are low-temperature boilers or condensing boilers, as well as to heating systems with a nominal output of less than four kilowatts (approx. 14,000 BTU/h) or more than 400 kilowatts (approx. 1,364,000 BTU/h), and to boilers according to § 13 paragraph 3 numbers 2 to 4.
So, as I understand it, only constant-temperature boilers have to be replaced, even in the case of a change of ownership after 2002, and low-temperature boilers do not.
Is that correct?
