ᐅ Gas heating, solar thermal systems, and wood-burning stove with water circulation: pros and cons

Good morning everyone,

I am planning a major renovation of a residential building and want to combine a gas heating system with solar thermal for domestic hot water and a water-jacketed wood stove for additional heating support.

Does such a setup even make sense?

I already have the wood stove. Can you recommend affordable systems? I basically need the entire heating system: gas boiler, buffer tank, solar panels including all accessories (except the wood stove).

Thanks in advance for your tips!

Only in exceptional cases. The more components involved in heat generation, the lower the overall efficiency tends to be (due to competing demands). This limits cost-effectiveness.
I would focus primarily on one heat source and optimize that system.
Reliable conclusions can only be drawn once the actual demand for heating and hot water is known.

That's exactly the case. You either prioritize solar thermal energy—not just for domestic hot water but also for heating support—and choose a large storage tank combined with a radiant floor heating system, such as a capillary tube system (supply temperatures 24-28°C (75-82°F)). In most cases, a wood stove alone is sufficient to cover peak loads. All of this can be easily calculated.
