ᐅ District heating pipeline supposedly heats the water supply

Hello dear forum,

In our semi-detached house, there was suddenly a change regarding the supply line for fresh water. Contrary to the original plan, the line is now supposed to come from the garden side instead of the street side – right through the middle of the garden, that is.

The reason given was that the district heating pipe (our heating system) would heat up the fresh water if both pipes were connected to the house at the same point. To prevent this, the two pipes are being separated spatially.

• Does the fresh water really get warmed if the pipe runs next to the district heating pipe?
• Can I object to this or have any influence on how the fresh water line is routed? The garden would now be split in half by the pipe, which could potentially restrict me in future building projects (pool, etc.).

Thank you very much for your help and best regards!

Is there ever a before and after plan available?

That’s complete nonsense. First of all, the service lines are never installed so close that heat transfer would cause the water to “heat up.” Besides, the district heating pipes are insulated; after all, the heat network operator wants to sell heat, not give the municipality an excuse to skip winter road maintenance.

Just report this to your water network operator. It likely won’t be allowed if a pool is planned. However, for an extended connection, you might have to cover the additional costs.
