Hello!
My uncle and mother inherited my late grandmother’s house.
Key details of the house:
- Semi-detached house built in 1955 with two 64 m² (690 sq ft) apartments and a converted attic.
- Gas heating (radiators) from around 1985 (Vaillant VKS 11 and VKS 17) WITHOUT central hot water supply.
- Windows from the late 1970s.
- Gas boilers in the bathrooms are also from the 1970s.
- Electrical wiring and plumbing from the 1950s.
- Roof was replaced in the 1980s but not insulated, apart from a layer of fiberglass insulation in the attic.
The initial plan is to renew the water supply and drainage pipes as well as the bathrooms.
My uncle wants to renovate as cheaply as possible since he plans to rent out his share.
He intends to only replace the cold water and wastewater pipes and provide hot water for the bathrooms using electric instantaneous water heaters.
Does this make sense, or would it be better to replace the heating system altogether and switch to a central hot water supply?
Regards,
Christian

Thank you for your response!
By now, a heating engineer has been there. He actually recommends tankless water heaters, since installing hot water pipes would supposedly be too complicated. And the existing heating systems are still "good," as their exhaust values are still acceptable.
He doesn’t seem to want to sell anything. I have advised my uncle to consult a second heating engineer.
Let's see if they share the same opinion.
