Hi,
I'm installing a wood burning boiler stove and a thermal store. Due to it's size, the store will be installed in the cellar approx. 3m below the boiler stove. A pump will drive the flow and return but I have been trying to think of a way to make it thermo-syphon in case of power failure.
My idea is to install a hot water cylinder directly above the stove and use this to drive flow through the thermal store under gravity. In normal use the pump system will restrict the flow to the cylinder but I'm keen to know if the gravity circuit through the store will work unassisted.
Does anyone know if it will work or have experience of anything similar. Any advice would be greatly appreciated.
