Treco has recently joined the UK District Energy Association (ukDEA). The Association is a not-for-profit, non-trade association of companies and public sector organisations involved or interested in district energy schemes of all sizes, from village scale, community based ‘micro district energy’ schemes to city wide district heat energy networks.
The Association has already attracted leading players in the industry, with the ukDEA’s full members comprising of 16 major organisations covering Birmingham, Coventry, Exeter, Leicester, Liverpool, Manchester, Milton Keynes, Newport, Newcastle, Nottingham, Sheffield, Shetland, Southampton and Woking.
We have installed hundreds of district heating schemes all over the UK including a housing development in Dorset. Perryfields is a 72-unit housing development, built by Lomand Homes. The development features an integrated mix of private ownership, affordable and 22 units of social housing.
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 re-circulation. 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 in the first instance but after time the development took advantage of the multi-fuel facility on the boilers and started using wood chips as this contributed to the energy efficiency and low cost objective of the development.
Each boiler supplies a network of houses and apartments 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. Heat Interface Units, fitted into each property, enabled automatic billing and the easy calculation of Renewable Heat Incentive (RHI) payments.
As well as delivering fuel cost savings of 20%-40% with wood pellets and 50%-80% with wood chips, Perryfields is now accredited into the RHI. This will enable them to gain significant payments per unit of heat generated and used by submitting quarterly meter readings to Ofgem.
A project of this size would gain upwards of £33,924 every year for 20 years, index linked to inflation.
In the longer term, control of the district heating system will be passed on to a tenant and owner, community-led company, giving long-term low cost of occupancy.
