This is gonna be long winded, so bear with me.
We recently moved into an old farmhouse in Aberdeenshire.
There is an oil Rayburn in the Kitchen which does the hot water. So well infact that we need to run off hot water a few times a day orelse the hot water tank starts boiling. And it goes through 8 litres of oil a day.
There is a wood stove in the living room which heats up that room. Our room and the kids rooms have open fireplaces. There is no other central heating in the house, and apparently winters in our area can get interesting. For example, i've been told that snowshoes (The tennis racket type) may be a good investment.
We got a quote for installing a CH system and that was 10K




Now.......
I would like to plan and install a central heating system. I don't want any electrical pumps as we have power outages, which would then mean that the CH can't be used or so i've been told.
So i'm looking at a larger water tank installed in the Loft to take care of the hot water. (I assume the cold water filler will need to be above that? Or just above the boiler on the rayburn?)
I was thinking of replacing the wood stove in the living room with one with a back boiler to run 4 rads ( i managed to get 3 old victorian cast iron rads) . It would ideally be a gravity fed system. And that is where i start running out of knowledge. The quote we got had a hot water tank for the water from the boiler. Something about a radiator to bleed off excess heat?
Anyone got any experiance in DIY CH systems who can shed light on what i need, and what i need to do?
