WT5 Wood Burning Heater

Wood Waste Technology
Turn your timber offcuts into free workshop heat — without an afterburner, and without falling foul of clean air regulations. The WT5 suits single-space workshops up to around 4,000 ft² that produce a moderate volume of mixed wood waste each week.

Typically chosen by

  • Small joinery or timber workshops looking to cut heating bills by burning their own wood waste
  • Workshops in city centres or residential locations that need a fully exempt appliance to comply with clean air regulations
  • Businesses heating a single production space up to around 4,000 ft² who want a reliable, low-maintenance solution

Key specification considerations

Heat Output
150,000+ BTU/hr (47 kW)
Sufficient to heat a workshop of approximately 4,000 ft², though actual coverage will depend on insulation, ceiling height, and draughts.
Fuel Consumption
400–650 kg per week
The range reflects fuel type — denser hardwood offcuts will sit toward the lower end; lighter softwood or MDF toward the higher end.
Approved Fuels
Chipboard, MDF, hardwood, softwood offcuts
Exempt Appliance
Yes — no afterburner required
Fully exempt status means this heater can legally be operated in smoke control areas, including city centres and residential zones, without additional equipment.

Exempt Appliance Status
Yes
Fully exempt status means this heater can legally be operated in smoke control areas, including city centres and residential zones, without an afterburner.
Firebox Construction
Full refractory-lined firebox
Refractory lining protects the firebox structure from sustained high temperatures, contributing to long-term reliability.
Heat Exchanger
Double-pass with fully welded heat recovery fins
The double-pass design extracts more heat from combustion gases before they exit the flue, improving efficiency compared to single-pass units.
Afterburner Required
No
Recommended Workshop Size
Up to approx. 4,000 ft²
Dimensions (L × W × H)
1,495 mm × 915 mm × 1,715 mm
Allow additional clearance around the unit for safe fuel loading, ash removal, and maintenance access.
Weight
Approx. 310 kg
Floor loading should be verified before installation — talk to us if you have any doubt about slab suitability.
Flue Specification
Stainless steel flue supplied per metre — diameter to be confirmed at point of order
Flue routing (wall or roof), run length, and any required summer heat-dump hood will be scoped as part of the installation quote.
Electrical Supply Required
Single phase, 15 A
A standard single-phase supply is sufficient — no three-phase installation required.
Certifications
DEFRA and SEPA approved
DEFRA and SEPA approval confirms the unit meets UK and Scottish clean air requirements, giving you the regulatory basis to operate in smoke control areas.

Is this the right
machine for you?

Choose the WT5 Wood Burning Heater if...

  • Your workshop is up to approximately 4,000 ft² and a single heater can cover the space
  • You are based in a smoke control area — city centre, residential zone, or similar — and need a fully exempt appliance
  • Your weekly wood waste output broadly matches the 400–650 kg consumption range, so you are not stockpiling or running short
  • You want the lowest capital outlay in the double-pass WT range while still getting refractory-lined construction and high-efficiency heat recovery

Consider an alternate model if...

  • Your workshop exceeds 4,000 ft² or you have multiple zones to heat — the WT10 or WT15 will provide the additional output needed
  • You generate significantly more than 650 kg of wood waste per week and want to burn it all — a larger model such as the WT10 or WT15 will match your waste volume more closely
  • Your space is smaller and a lower output unit would be more appropriate — the WT2 may be worth discussing with us first
