6 x Windhager BioWin Excel 60kW in a cascade system
360kW Biomass boiler system supplying heat and hot water to the 124 bedroom hotel
Potential of £45,000 per year for 20 years under the non-domestic RHI scheme
Following the survey and subsequent quotation provided for the installation of a 360kW biomass boiler system Greenguru Northeast was awarded the contract for the supply, installation and commissioning to Cumbria Grand Hotel in the Lake District.The 6 x 60kw Windhager boilers replaced the existing inefficient gas fired boilers.
It was agreed the system would be installed in the existing boiler room area, the 10 metre x 6 metre extinct storage area was ideal for the new installation.
The plant consisted of 6 x 60kw Windhager boilers in a cascaded system, buffer vessels, all ancillaries and flues to each boiler, the flues protruding through the existing roof structure.
A 40ft steel container was modified to house the pellet store and situated on land external to the plant room. Pellet feed tubes ran from the feed container through the plant room wall to each individual boiler.
The hotel’s heating and hot water are now renewable energy driven. The expected RHI returns are £900k over a 20 year period with an estimated payback period of 4.8years on investment.
