Water-bearing fireplace stove in new construction - yes or no?

Hello everyone,

I was almost a bit surprised that I couldn't find a somewhat current entry on this topic (if I missed something and unnecessarily created a new post, I apologize ).

To the actual topic:
We are building a new house (solid construction, no special insulation properties) that is to be heated by a heat pump.
A wood stove is planned in the living room and now we are faced with the question: water-bearing yes or no?

I actually approached this undertaking with the firm belief "of course water-bearing, why not, that way the wood stove can also be used for hot water and heating water." The voices of the first stove builders, however, are now making me doubt a bit ("the additional costs can hardly be earned back by heating etc."). So I thought I’d ask here for experiences from other builders on the subject.

So as the title already says, water-bearing wood stove in a new building - yes or no? I would really appreciate one or two opinions and experiences.

Best regards
DerToni

We asked ourselves and our stove builder this question as well. I found the idea exceptionally charming and expected further resource conservation from it. I was aware that I would not produce hot water with it all year round, but that it (in our case) would operate as a secondary system to a small air-to-water heat pump. My stove builder explained the system to me. Due to the system, the efficiency decreases with the degree of soot buildup. Therefore, cleaning is required from time to time. This procedure in the living room or on the wooden terrace deterred me. So we built a masonry stove without water circulation.

If the heat pump is installed, omit the integration of the fireplace. To bring high and low temperatures together, you need a separation buffer. Aside from the control difficulties you introduce, you significantly reduce the efficiency of the heat pump. A modulating heat pump also makes no sense with a separation buffer. You will never recover the investment costs.

Better build a stove with very high storage mass => [Grundofen].

If you want a really efficient heat pump, then have it properly planned. Set room temperatures for each room, calculate heating loads room by room, ...

Usually it helps to educate yourself and not just let the heating engineer do it.

We have also moved away from the idea of a water-bearing masonry heater. The stove builder advised us against it mainly due to the investment costs. He also said that you would need a correspondingly large domestic hot water storage tank so that the whole thing doesn’t immediately boil when you really heat it up.
And having to heat that huge storage tank in summer with the heat pump obviously makes little sense.

Now it will be a "simple" masonry heater. I'm curious whether we will manage the supplementary heating for the underfloor heating as I imagine.

The question haunts at least once every year... and as many before me have said, a regulatory nightmare.

Alleged savings and use of waste heat only on paper in the glossy brochures and from the stories of the sellers and brokers.
