Tiled stove in combination with air-to-water heat pump experiences?

Hi, this is not a good idea. Water-bearing stove means that only a small proportion <30% of the heat goes into the water. The lower the temperature of the stove, the less the water is heated proportionally. You don't want to sweat in the living room and have lukewarm water.

We have a Panasonic monoblock 9kw air-water heat pump with 8kw fireplace insert in the living room. The fireplace insert is a backup for heating the living room in case the heat pump breaks down. In the hot water tank there is an electric heating element as a backup. Otherwise, the heat pump heats water and underfloor heating at the lowest temperatures because that is the most comfortable.

May I ask which fireplace insert you have?

A tiled stove usually only emits about 20-30% of the energy through the glass pane. This is a significant difference from a fireplace, among other things, which is why a tiled stove cannot have so many glass panes. Depending on what kind of tiled stove you have, the remaining 60-70% of the heat is delivered to the hot water circuit. Additionally, there is heat storage capacity in the stones.

Fireplace is NOT the same as a tiled stove.

I have a Haas & Sohn Komfort IV 8kw. Installed and clad myself with Knauf red lime boards made of perlite. The insert cost about 1200€, ventilation grille, inspection door for temperature sensor underpressure monitor, special fabric, boards, and plaster were also about 1000€.

The insert is just for fun and no comparison to the heat pump.

Thank you. I am looking for experiences with a real tiled stove, preferably in combination with a heat storage mass and, as the icing on the cake, with a Moritz flap and also water-bearing ;)

Topic storage mass. The wall behind the insert is 24cm of calcium silicate brick and therefore has a good amount of storage mass. However, the wall always has to be insulated because of the requirements from the chimney sweep.

I am convinced that there is no difference between an insert and a tiled stove. In both cases, the living room is overheated so that the water gets warm. The stones of the tiled stove charge more slowly, but as soon as they are loaded, you have a little sun in your living room.

In new buildings, a tiled stove is really difficult. Have your heating load calculated, then you will find that it becomes uncomfortable to heat a 2kw living room with a tiled stove.

These are worlds apart, especially when it comes to the flue ducts. A crucial role is also played by how the heat exchanger is built and cleaned. Contaminations can quickly cause efficiency to plummet.

Exactly that happens with a fireplace when 80% of your 8 kW is suddenly released into the room. Then you have 6.4 kW of direct heat all at once. Better get the sauna towels out. A tiled stove with proper flue ducts stores the energy produced and releases it over hours. Also, a proper tiled stove is not refueled every 30 or 60 minutes, but it burns steadily for 2 to 4 hours. The exhaust gas temperature passing through the chimney is also significantly lower.

Thank you. A tiled stove is significantly more efficient than a regular chimney, and you yourself say that your neighbor uses it as the primary source. The costs can also be very low. I'm not talking about just putting it together and being done, but about intelligent combinations. When I heat the stove, the air-water heat pump doesn't have to keep working. It's clear that enough heat will come from the stove over the next 2-4 hours. The stove and the air-water heat pump should be able to communicate with each other…

I can't imagine that it works. An air-water heat pump is not like a central heating system. You turn it down to zero, and it's off. It takes hours for it to go to zero.
