Wood Pellet Boilers

The Hargassner Wood Pellet Boiler range is summarised here. For more detail regarding each unit please read the Hargassner brochure which can be accessed as an electronic copy, here

Wood pellets for fuel are made up of waste wood material such as sawdust, which is compressed to form a pellet and produce small amounts CO2 emissions. Pellets have a high calorific value for a smaller weight compared with other biomass fuels. They require a dry storage area as moisture can affect their efficiency, this should typically not need to be re-fuelled more than once per week (for manual refill units). Where space allows, larger deliveries of pellets can be arranged by lorry which would result in a less-frequent need for refuelling and can be fuelled by additional automated components. 

Manual or automatic fuelling options are available within the Hargassner range, as well as a variety of storage solutions for differing property types.
