A back boiler is designed to provide your home with heat and hot water and is a great alternative to a external boiler. Unlike a wall mounted boiler, a back boiler is installed behind your fireplace stove meaning you save valuable space in your home.  It heats water in a storage cylinder and despite it’s size it is more than capable of providing your home with all the pressure requirements, heat and hot water that you need.
