Lomand Homes wanted the Perryfields development to incorporate highly energy efficient homes with low occupancy costs. The properties were designed to make the most of insulation, low energy lighting, heat recovery and recirculation. Biomass district heating was specified to also give the development energy efficient heating.

Treco supplied and installed three 100kW Guntamatic Powerchip biomass boilers, commissioned to burn wood pellets. Each boiler supplies a network of houses and appartments via a large district heating scheme. The system delivers low operating costs and automatic ash removal.

The boilers were each installed with a 2,000 litre buffer tank. Large fuel stores automatically feed wood pellets into the boilers. Heat is supplied to each unit via an underground heat main. Consumer Interface Units were fitted into each property, enabling automatic billing and the easy calculation of RHI Payments.
