How the Relax Woodburning Workshop Stove Works
Pricing & Order Online
The Primary Air Tube delivers pre-heated primary air (1) for combustion, right to the heart of the fire bed, making it practical to burn wood, sawdust, shavings, chippings and dry waste.
A second valve supplies secondary air (2) into the smoke stream, aiding combustion of unburned hydrocarbons, resulting in a cleaner burn and improved thermal efficiency - producing more heat. It also ensures that the Relax Range complies with the EC Declaration of Conformity EN13240 regarding smoke emissions.
When burning hardwood off cuts, the three larger models will last through the night without attention.
A grate ensures the ash is removed (3) and a small door enables ash removal.
Every Relax Woodburning Stove is fitted with a Safety Guard, a cast iron top rim to aid diffusion of heat, a cast iron Grate for longer life and a Top Plate for refueling.
Relax Woodburning Stoves - the most economical
and environmentally friendly way to heat your
Workshop, Industrial Unit or greenhouse, resulting
in cost reduction of waste removal and reduction of
heating bills. Payback can typically be less than 12 months.
Burning wood is environmentally acceptable, as the cycle of growing and burning wood is CO2 neutral.
1 - Physical Size
The dimensions of a stove assist the design considerations
and determine the volume of waste that can be burnt.
To help judge what size of stove you need there are two major considerations.
2 - Heat Production
The heat required for a workshop is about 6 kilowatts
per 100 cubic metres
Main Flue Length
A minimum of 3 vertical metres is required to achieve a reliable draw. Terminate a flue above the eaves of a building and preferably just above the ridge, avoiding unsupported lengths.
Choose from 90o and 45o bends, but smoke does not travel horizontally, so avoid long horizontal sections.
A standard Rain Top is sufficient for most applications. Swivel Cowls are required for adverse wind conditions e.g. near trees, taller buildings or flue termination below a ridge.
Where a flue passes through a roof, a flashing will be required.
