Relax Woodburning Workshop Stove - How It works

How the  Relax Woodburning Workshop Stove Works

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 smokestream, aiding combustion of unburnt 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 refuelling.

Relax Woodburning Stoves - the most economical and environmentally friendly way to heat your Workshop, Industrial Unit or reenhouse, resulting in cost reduction of waste removal and reduction of heatings 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 dimesions 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

Flue Selection

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.

Bends

Choose from 90^o and 45^o bends, but smoke does not travel horizontally, so avoid long horizontal sections.

Cowls

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.

Flashings

Where a flue passes through a roof, a flashing will be required.
