This home in East Lothian was extended and required an energy efficient heating solution to replace the existing oil fired boiler. The customer wanted to utilise renewable technology to conserve energy, reducing both energy bills and carbon footprint.
We designed a biomass heating solution in house, to heat the entire house including the extension. The heating system, a two boiler module of Grant Condensing Biomass Boilers, was located in an external outbuilding. This was fed underground into the house, to provide five fully controlled heating zones with two of these zones being underfloor heating.
The biomass system burns wood pellets and these are stored in an external hopper that feeds the boiler automatically, requiring minimal maintenance. The hopper is filled every couple of months, as required, by the local pellet supplier.
Domestic hot water is divided between two tanks located at each side of the house. The main hot water cylinder is connected to solar thermal panels that are installed on the roof. In summer-time, the solar panels take over the hot water heating, while the biomass heating system is used as a backup, saving both fuel and energy.
