Nowadays, low-temperature systems are also made with gas in single-family homes. Gas is simply more robust. But whether you still have a fireplace, possibly with a water jacket, does not matter in this case.
Here with me it often is -10 degrees in winter and continuously. Therefore the question about a sensible combination. How reasonable is the idea to use the water-bearing fireplace for an outbuilding? I have 100sqm of outbuilding.
Then ditch the heat pump stuff. Those things are absolutely worthless for that. Make a nice pellet heating system, it is much more efficient and simple to operate. Earth tank if necessary in the garden, if there is no space in the house.
Then I would recommend a brine heat pump. The water-conducting fireplace and the heat pump are two things that also clash. Maybe better gas instead of a heat pump?
What costs should one expect for a brine heat pump?
There are also companies that sell orgonite. Super expensive, but they say it helps against electrosmog and many people feel much better since they have orgonite with them...
"Orgonite is a fascinating object composed of semi-precious stones, resin, and metal particles and is known for its regenerative effect on the entire environment. It is primarily used to combat electromagnetic pollution, but also to increase the vibrational rate of a place or person, which stimulates healing. We are talking about orgone energy, which transforms negative energies into positive energies. This orgonite pyramid “Protection & Cleansing” contains the most beautiful stones such as obsidian, labradorite, but also lapis lazuli and clear quartz. It is a perfect set to protect your environment from negative energies so that the orgone energy can absorb this negativity to harmonize and cleanse your inner self." :eek::eek::eek:
