Hello everyone,
I once came across a solution where a heat exchanger is installed in the chimney or its hot exhaust gas flow, which is then used to transfer additional heat to the heating system for support.
Now my question is: What happens if the power goes out and the pump cannot operate? Would I then be unable to use the chimney as well?

Forget about that with a heat pump – it only leads to problems and frequent cycling. With gas, it works... I would rather go for a water-based fireplace in that case.What exactly for problems?

The efficiency and therefore the annual performance factor decrease, and essentially, you’re only causing additional costs.

Could you please explain that in more detail?

There was also a study by the Fraunhofer Institute that clearly demonstrated the efficiency decreases when using a buffer.
