Hi all!
I live in Turkey and we use a thermal solar water heater most of the year around. We are renovating and putting in underfloor heating (water). I would like to have a system that prioritises the 3 available redundant heat sources according to impact.
- use solar heat as long as there is enough sun for low-temperature underfloor heating.
- switch to a boiler situated in/behind a wood powered stove when the heat from solar is insufficient
- switch to an electric resistance int he boiler in case the wood stove isn't on.
Does anyone have an idea on how to efficiently engineer this ? Local engineers are fixated on the condensation heaters they sell (gas/coal) and don't engineer redundant systems.
Is it even feasible ?
Thanks in advance for any helpful comments!
