Compared with Si12 the Si20 has a larger firebox and a substantially more complex heat exchanger featuring both larger tubes and insulated side and rear flat heat exchangers. Due to the heat high output required whilst maintaining sensible refuelling intervals, this product has been initially designed as a solid fuel boiler stove suitable for burning all approved smokeless fuels.

The Si20 produces a maximum of 20 kW peak heat output with 10.3 to water and 9.7 to the room and is suitable for heating small to medium size houses or as part of a link-up system alongside another boiler for a large residence.

This stove is built form heavy gauge steel that’s fully seam welded to ensure longevity. It also features a full width riddling grate and ashpan for thorough de-ashing. Our tactile air control allows fine tuning of air flow alongside a boiler thermostat that is fitted as standard so you can easily adjust to get the best burn and optimum heat output. The boiler heat exchanger tubes can also be easily accessed through the door opening to allow easy cleaning of the tubes to maintain peak efficiency and safe flue performance .
