Dartmoor National Park

Dartmoor National Park
5D Group were asked to complete the installation of a 180kW Herz boiler installation at the Dartmoor National Park Centre and Duchy Offices in Princetown. This replaced the existing oil fired hot water and heating system which was proving inefficient and costly to run.

The location of the Biomass Boiler is in one of the highest parts of the Moor and the design included a need to keep the wood chip dry through the winter period and to reduce the number of deliveries. We listened carefully to the requirements of the Dartmoor National Park team and in addition to our own labour we used a mixture of local sub-contractors and a local fuel supplier to complete the project making this an example of local businesses within the National Park working together to promote sustainability.

A small district heating system was installed to take heat from the Boiler Room to both the Dartmoor National Park Offices and the Duchy Office next door. The design included the installation of a new Building Management System to replace the existing one which had not worked for a number of years so improving the efficiency of the entire heating and hot water system.

The business case presented estimated a return on investment in around 4 years and the first year of operation has seen a net gain to the National Park authority of around £25,000 (made up of RHI, fuel cost savings and fuel sold to the Duchy office) which is in line with expectations.

Ali Bright of the Dartmoor National Park Authority says "this was an opportunity for the National Park Authority to use local resources to provide heat and hot water to one of our key buildings which was a major drain on our energy resources. We were delighted 5D Group chose to use local suppliers to maintain true sustainability within the Park and have been delighted with the results so far. The installation was well run and trouble free and is proving to be an excellent long term investment for the National Park Authority.
