The Si12 produces a maximum total heat output of 12kW with 5kW going to water and 7kW to the room. This is suitable for heating a small property or for use in link-up systems for topping up alongside another boiler.
The boiler stove is built from heavy gauge steel that’s fully seam welded to ensure longevity.
The stove can be used with a insulating grate insert for efficient and clean wood burning and features a full width riddling grate and ashpan to assist with de-ashing when burning smokeless fuel.
Tactile air controls allow fine tuning of air flow so you can easily adjust to get the best & most efficient burn.
The boiler heat exchanger tubes can be easily accessed for cleaning through the door opening, unlike many old boilers where you are required to remove dusty dirty baffles for regular maintenance.
