A Remeha 100kW biomass boiler is bringing energy efficient, low carbon heating to the newly opened Visitors’ Centre at the Duchy of Cornwall Nursery at Lostwithiel, Cornwall.

The new building, which was officially opened by The Prince of Wales and The Duchess of Cornwall on July 12th 2011, is a testament to the Prince’s vision of sustainability in the built environment. Remeha Commercial’s biomass boiler is playing a key part in this inspiring example of low-energy building for the future.

The state-of-the-art 100kW Remeha-Gilles biomass boiler provides heating for the shop and café building as well as the new greenhouse area. This modulating, fully controllable biomass boiler is fuelled by locally sourced low to zero carbon wood pellets, making it environmentally sound and economically viable. The fuel store at the Duchy of Cornwall Nursery can hold a sufficient supply of pellets for least 21 days in winter to minimise fuel deliveries.

Remeha has also supplied a day pellet hopper in the boiler house to give the option to load 10kg bags of pellets manually should adverse weather prevent delivery. A palate of pellets is stored near the boiler house.

The replacement of the oil-fired heating system with a biomass boiler is the latest initiative contributing to the reduction of the carbon footprint of the Duchy Nursery by 70 percent: recent changes to electricity supply contracts have reduced the carbon footprint by one-third on baseline, and the wood pellet system will reduce the footprint by another third.

The new Visitors’ Centre sits well within the local landscape, incorporating the Prince of Wales’ environmental vision. As part of the transformation of the Nursery, the plant retail areas have been improved to stock the 4,000 plus varieties of plants and trees, and a new entrance and car park have been created. In addition to the biomass boiler, the new site includes a number of renewable features including rainwater harvesting and high levels of thermal insulation. The building itself is constructed using natural materials wherever possible and utilising local craftsmanship. In the cafe, traditional recipes are on offer, created from seasonal, locally sourced ingredients supporting West Country producers.

This project is the third collaboration between Remeha Commercial and the Duchy of Cornwall. The first, back in 2008, was a Remeha-Gilles 360kW wood chip boiler installed at Restormel Manor. More recently, the Duchy of Cornwall has installed a Remeha-Gilles 30kW wood pellet boiler in Tor Gate, a fully restored farmhouse on Dartmoor.
