Wood Pellet Boiler Technology
Wood pellet boilers are an environmentally friendly, safe and convenient way of heating the home, using wood pellets as fuel. They differ from traditional solid fuel boilers. Apart from the green aspect, the units are fully automatic and behave more like an oil or gas boiler, using advanced controls which cleverly regulate the amount of fuel being delivered to the burner to match the heat demand on the boiler. The fuel is fed to the burner via an auger connected to the adjacent pellet store/hopper. This can, in turn, be automatically supplied from a bulk pellet store which can vary in size.
The process of burning wood produces ash, so most pellet boilers require regular, tedious cleaning and maintenance but Grant have found a better solution with their unique “Self Cleaning” boiler design, reducing the need for cleaning to once a year under normal running conditions.
The brief behind the Grant Spira Wood Pellet Boiler range was to insure installation was straightforward, daily operation easy and maintenance as effortless as possible, whilst guaranteeing the same high quality and efficiency everyone expects from Grant products.
The units are available in outputs of 6-26 kW with an efficiency of 97.4% gross, and 9-36 kW with an efficiency of 93.1% gross. They come complete with a 110kg pellet store/hopper and feed auger, which automatically supplies the Spira with fuel.
The Grant Spira Wood Pellet Boiler was recently awarded Best Renewable Energy Product by the Sustainable Energy Authority SEAI.
