Were probably going to do an extension next year and will also be replacing the oil boiler so it’s an opportunity to modernise the heating system and upgrade the insulation.
Currently I have an ancient oil boiler, which works but is probably about 25 years old, in the last few years it’s been a secondary or occasional system, most of the space heating is done with a boiler stove so when I’m getting a new condensing oil boiler in im pondering a thermal store tank, maybe something like this:
I would like to store heat from the stove and the boiler and also maybe have an additional coil for solar to perhaps be installed at a later date.
Anyone got any experience with them? Is it possible to directly heat the tank and not the house from all the sources (not neccessarily at the same time)?
