Grant Outdoor Module Oil Boilers

An innovation in central heating, the Grant Outdoor Module cuts cost dramatically as little or no building work is necessary. It comes complete with a built-in multi-directional low level flue and can be either fixed against any suitable external wall, or installed freestanding allowing for the necessary clearances around the flue terminal. A conventional flue starter elbow is also available, allowing the flue to run vertically when siting conditions restrict low level applications. Their advanced heat exchanger design forces the hot gases through a patented baffle system. This process vastly increases the amount of heat transferred to the water jacket, enabling the boiler to operate continually at much higher efficiencies.
