A 120kW Pelleburn domestic installation in a beautiful property in the Shropshire countryside that was running on oil to heat the property. The owners wanted to drastically reduce their CO2 emissions and switch to a more sustainable source.
THE CHALLENGES IN THE DESIGN
The old oil boilers were in the basement of the main property, which was also prone to flooding due to being below the water table. A new site had to be found to house the Biomass Boilers so that they wouldn’t interfere with the original building and be above any water line. Being a domestic property with a 120kW Thermal Heat demand, the correct boilers had to be selected to meet this requirement.
Heating a property of this size on the current fuel is unsustainable. An alternative was required.

THE FINAL DESIGN
The decision was made to create a purpose built unit that would enclose not only the three BURNiT 40kW PelleBurn boilers but also the 2000 Litre Sunsystem Buffer Tank and 4 Tonne Silo. The three boilers were connected to the buffer tank in such a way that they would only come on when there was a drop in temperature within the tank. The greater the drop, the more boilers would operate. This meant that there was always enough hot water in the tank to meet demand.
