I had a similar idea when I was designing a heating system for a mountain house I was planning on building. I was planning on primarily heating with an oversized wood stove. The excess heat the wood stove would produce would be captured by a heat pump inside the house with its coils in a 500 gallon tank of water that was well insulated. When the house needed heat you could run the heat pump in reverse or make a system that removed the insulation around the tank of water letting the heat out. I had a spreadsheet with the heat calculations. I think the water at 150F degrees had around a megawatt of energy stored in it and that could have heated the house for a couple weeks. I never ended building that house, but would love to build a system like this in the future.

Back when I had mine, it kept the water at 180F. https://en.wikipedia.org/wiki/Outdoor_wood-fired_boiler https://en.wikipedia.org/wiki/Outdoor_wood-fired_boiler If you have enough sufficiently dry wood, downdraft gasification models burn extremely cleanly (they're effectively rocket stoves), but those models require a fair bit of maintenance, especially if your wood is slightly wet or green, because soot can quickly build up on the water envelope.

Then you use the water storage for next days until you have to re-fire. That is a standard package provided by many companies from Austria and Germany.
