Boiler: An Angus Super 40kW Wood
Gasification Log Boiler was selected with one Nad
and one Nado 1000 litre accumulation tanks. Wood pellet boilers were
rejected as the owner has access to an existing free wood supply on the
property and wanted to utilise both unseasoned wood dried out on site
and waste wood off cuts.
Boiler Location: The boiler is situated in a covered area at the
back of the property. The boiler is covered from direct rainfall with a
small pitched roof, but the unit remains open to the elements. The total
boiler height is 1570 cm and 600 cm wide and is fitted against the north
facing back wall of the property.
Water cylinder tanks were accommodated inside the property, creating a
large room used for drying clothes and storing linen.
Project delivery: The project was completed in a very short
period of time. From boiler choice, the delivery was made within two
weeks along with the accumulator tanks and additional elements of the
heating package, including; Laddomat 21-60 Mixing/Layering
Valve,Thermo Safety Valve, Wilo Pump and three Way Valve.
Installation was relatively simple as a room already existed in the
property for the water cylinder tanks. Installation and commissioning
took just three days.
Wood Fuel Management: It was estimated that an average
of twelve tonnes of wet wood would be required annually (mixed variety
hard and soft wood). The property could generate 50% of this capacity
and had an existing store of wood to accommodate the first year of
operation made up of seasoned wood off-cuts ready to be used
immediately. An additional supply of unseasoned hardwood was
purchased, split and dried on site in the log store for a minimum of one
year. As the property already had a small wood burning stove, there
was an existing log store on site.
