We already have a big[gish] multi-fuel stove in our main room. As we have just acquired a *lot* more wood to burn we're considering putting one in the breakfast room as well.
Given that this is a money saving idea (to reduce use of electricity in particular) we want it to be as cheap as possible. (Don't tell me gas is cheaper, we don't have mains gas).
Is the cheapest way normally to D-I-Y and then get building regs approval or is using a HEAT approved installer better? We're probably looking at a 5 or 6kW stove costing around £250 for the stove itself, or maybe even a secondhand one, what are the additional costs likely to be with (probably) the flue going out through a hole in the wall above the stove?
Finally I see that it's not allowed to have an extract fan in the room with the stove (for fairly obvious reasons). Our breakfast room where we want to put the stove is adjacent and open to the kitchen which has a cooker hood which has an extract fan. Is this OK? The archway between breakfast room and kitchen is larger than a normal doorway but not huge.
