Hi,
I'm planning a wet UFH heating system which will be using a vented cylinder coupled to a wood stove, gas boiler and electric thermostat.
Later on I'll add solar PV panels, which I'll set to power the immersion heater if they're generating spare leccy instead of exporting.
To make the most of all this 'free' hot water (from the back boiler if the stove is on, and the solar -> electric heated water), I wonder if it's possible to set a thermostat to use one temperature if the water is free, but only actually fire up the boiler if the temp in the house falls beneath a second, lower temperature?
I like the idea of being able to heat the house to a more 'luxurious' temperate if I've got the stove producing hot water anyway.
Possible?! Thanks!
