In March 2016 the Estate put in a 500 Kw biomass woodchip boiler (Hertz) to heat up Deene Park House together with a number of residential properties, our workshops, greenhouses and the Estate Office. In the late winter of 2016 the Estate felled approximately 250 tonnes of timber that was stockpiled for two years which has been chipped and used in the biomass boiler. We are really pleased to say that we are now using chipped wood from our own woods, which is not only economical but is also a sustainable way of providing heat and hot water.
The process of felling small areas within our woodlands, known as ‘coups’, breaks up the canopy and allows light to reach the woodland floor, reinvigorating growth and enabling greater biodiversity. The Estate needs to fell approximately 250 tonnes of green wood a year which converts to roughly 200 tonnes of dry wood once it has been left in piles around the Estate, where it air dries to roughly 20% moisture content. Within the felling coups the Estate has planted up trees to replace those that have been harvested.
The Hertz 500 Kwt Biomass Boiler was installed by J.L. Phillips (Newark) and they also put in the District Heating System.
The Estate renovated an under-utilised concrete portal framed shed converting it into a 200 tonne woodchip store.
The timber was chipped by Peter Lord Forestry Ltd who did a first class job of chipping the timber and providing the transport to our woodchip bunker.
