Cornish garden turns to CHP

Trelissick Gardens in the UK’s Cornwall has become the first National Trust property in the country to install an LPG-fired CHP unit.

Rurally located near Feock, close to the city of Truro, Trelissick Garden will use a Baxi DACHS mini CHP unit.
The move followed a decision to extend the restaurant and café, which used to rely solely on Calor LPG to provide fuel for the onsite catering facilities.

Trelissick Garden estate manager Chris Curtis said: ‘At the National Trust we are always looking for ways to minimise our environmental impact and we try to consider greener options. So when deciding on a solution for Trelissick’s expanding heating and electrical demands, it was important that we chose something which could offer both environmental and economic savings. We considered various options, including biomass, but this was deemed inappropriate as we don’t have any woodland that would provide the fuel for such a system.’

Robert Beeman, senior engineer at SJH Design Services, said: ‘In the design process, we established that there would be a base electrical load 24 hours a day and seven days a week and, for most of the year, a base heat load requirement. This made the choice of a CHP unit a natural one.’

The CHP heat output is supported, as required, by standby LPG fired condensing boilers controlled by the building management system.
