For our heating system in a new build (about 180m² (1937 sq ft)), we want to use a combination of a water-based fireplace, gas boiler, and solar panels. The rooms will be heated with underfloor heating.
I would like to install the underfloor heating myself and am considering a heating system with an integrated panel with knobs.
However, I’m a bit uncertain about which manufacturer to order from. The basic principle seems fairly simple...
Where would you place the in-wall manifolds? On the ground floor in the utility room and on the upper floor in the hallway?
How do you route the individual heating loops from the other rooms to these locations? 🙂
Maybe someone can recommend a manufacturer and share some tips with me.

Place the two distribution manifolds as centrally as possible so that all supply lines are kept as short as possible.
If you look into it more closely, unfortunately, your plan is not practical in several ways, even though it initially sounds great to support heating with a fireplace and solar energy.
Your idea makes the hydraulics and control system complex and expensive, resulting in inefficiencies (buffer tanks, different temperature levels, storage losses, pumps, etc.). Also, keep in mind that the heating system will eventually need to be replaced, and you will face the same complexity costs again. Especially with gas, operating costs per kWh are low. With solar thermal and/or the fireplace, you probably won’t achieve a truly green solution.
My suggestion would be:
- Use an affordable gas boiler and keep it simple. Alternatively, a heat pump with optional photovoltaics.
- Leave out solar thermal—if required for KfW certification, consider a ventilation system, decentralized if necessary.
- Plan the underfloor heating properly (supply temperature max. 30°C (86°F)) so you are prepared for a time after gas.
- During operation, open all thermostats and regulate centrally via the supply temperature.
- If you want a fireplace, do not connect it to the heating system.
- Photovoltaics are possible but have little or nothing to do with the heating system itself.
