Back boilers are a way of making maximum use of the heat that your fireplace or stove produces.
They’re not very common but were very popular in the 1960s, 70s and 80s.
Back boilers are good at heating homes and hot water, and can provide hot water to multiple outlets at the same time. However, they do take up a lot of space and aren’t particularly efficient.
Is a back boiler right for me?
Using a back boiler is probably not the best way for you to heat your home and water due to their size and relative inefficiency.
Of course, if you already have a back boiler then you know that you’ll have room for a new one. However, you’ll probably be better off with a more efficient alternative.
