The family-sized Graphite Boiler will easily heat up to 10 radiators, plus provide more than enough heat for the room its located in, as well as a generous supply of hot water. Its big fire chamber will take large logs up to 400 mm (16) long or a large 4kg smokeless fuel load to extend the burn times. The baffle plate and boiler top area can be inspected and simply cleaned through a special hatch underneath the heavy duty heat-sink lid (a staggering 26kg!) without having to remove the flue pipe. Top or rear flue options and an external riddler are just some of the Graphites many features.
