When plans were put in place for a new headquarters for Loch Lomond National Park, renewable energy for heat and hot water was a pre-requisite. The Park authority specified a wood chip boiler for their iconic National Park HQ and commissioned HWEnergy as the installer. The biomass heating system has been running since 2007.
Our biomass installation was in many ways a leap of faith at the time we specified it, given the lack of wood chip suppliers and our smokeless zone location. But as a public body with a very clear sustainability remit it was important we make that leap. It has proved to be an excellent decision. We have generated a huge amount of interest in our experiences with biomass and have hosted a number of special site visits to view our installation. We found HWEnergy very helpful and a real partner."
System: 100kW wood chip boiler with spring agitator fuel out-feeder and accumulator heat storage capacity.
Carrochan - An exemplar of sustainable construction.
Loch Lomond and the Trossachs National Park was designated under the National Parks (Scotland) Act 2000 and the Park became fully operational on 19 July 2002. The stunning £5M ‘Carrochan’ building, the National Park HQ, was completed in 2007. The installation of a wood chip boiler for the National Park HQ has enabled it to achieve an excellent BREEAM rating (Building Research Establishment Environmental Assessment Matrix) at design stage.
Sustainable heating at Carrochan
HWEnergy installed a 100kW wood chip heating system at the building which is fed from an underground fuel store. The boiler provides base load heating to the building, with a secondary gas boiler installed for back up /top up purposes. Wood chip fuel is bought in from a local supplier ensuring the economic benefit is kept within the National Park area.
The wood chip fuel is tipped directly by the delivery vehicle into the underground storage bunker which has a capacity for approximately three weeks supply of fuel. The bunker is accessed from secure lids located at ground level. The wood chip fuel is then fed by spring arm out feeder, extracting auger and intermediate stop-auger to elevate the fuel up to the boiler which is installed at ground level. The provision of the watertight, large underground silo enables wood chip fuel to be delivered extremely quickly by a standard tipping trailer with no specialist equipment required. The boiler installed is a very high specification 100kW Froeling ‘Turbomat’ boiler complete with such features as auto ignition and auto heat exchange cleaning. The boiler is installed in conjunction with heat storage accumulator tanks which provide a storage buffer for peak load heating times, and reduce boiler ‘short cycling’ during periods of low heating load.
