ᐅ Combining a heat pump with a hydronic fireplace

Honestly, I don’t think that’s the case. Especially since there is a company promoting exactly this concept.

Definitely do it and then share your logs as well as your efficiency values for the days when the wood stove is off after one year. This could serve as a great cautionary example for others.

There are also companies that sell orgonite. It is very expensive, but they claim that it helps against electromagnetic pollution and that many people have felt much better since they started using orgonite...

A heat pump operates quite inefficiently at -20°C (−4°F), which is exactly why I am asking this question..

This question is relevant to only a few people in Germany. Where do temperatures regularly reach -20°C (–4°F) for extended periods?

For high-altitude construction, this might indeed be more relevant.

Here in my area, it often stays around -10 degrees Celsius (14°F) throughout the winter.
That’s why I’m asking about a practical combination.
How practical is the idea of using a water-bearing chimney for an outbuilding? I have a 100m² (1,076 ft²) outbuilding.

Here where I live, temperatures often drop to -10 degrees Celsius (14°F) in winter and stay that low continuously.

In that case, I would recommend a brine heat pump. A water-bearing fireplace and a heat pump can interfere with each other. Maybe gas heating would be a better option than a heat pump?
