Design characteristics

  • Thermowood barrel with facing benches for three to four
  • Electric heater on a guarded wall in place of a stove
  • Curved section for quick warm-up
  • Small door window as the only glazing

Construction notes

  • Thermowood stave barrel drawn together with steel bands over end walls
  • Light insulation; geometry and mass carry the heat behaviour
  • Electric heater and controller with correct clearances
  • Cradle on gravel, piers or skids, pitched to drain from the door

Heating profile

  • A 6–8 kW electric heater suits the barrel volume
  • Moderate stone capacity for a balanced session
