Behind Bench Heater

The Oceanic behind bench heater with OCS-B controls is a wall mounted unit that is located behind a false wall at the rear of the cabin. There are many advantages of this model of heater


  • Built for heavy duty use
  • Protected heating elements
  • Rocks do not come into contact with heating elements 
  • Drip and eveporation trays control the water dosing. This prevents water being splashed directly onto the elements which is a common cause of element failure in standard sauna heaters.
  • A water dish and hose are fitted with the behind bench heater, users pour water into this dish mounted behind the false wall and the water is distributed evenly across the rocks.
  • Safer to use - prevents any accidental injuries from users being able to come into contact with the hot surfaces of the heater
  • More energy efficient

Electrical Information

Important Information 

  • Sauna heaters do not operate from a 3 pin plug, they require hard wiring via an isolator switch using high temperature silicon rubber cable to BSEN 6141 (not included). Purchase 3 Meters as an optional extra or See our sauna accessories page for Silicone Rubber Cable in order to order different lengths.
  • For sauna heaters with Remote OCSB controls, the control box will supply the heater, keypad, lights and temperature sensor. The control box is usually positioned on the roof of the sauna but can also be positioned in a plant room for commercial establishments.

Running Costs 

The cost to run an average heavy duty commercial sauna cabin with a 9kw heater is £1 per hour until the sauna cabin has reached temperature, after which the heater will maintain the temperature in the sauna using sequential heating reducing the running cost considerably. (using an average unit cost of 12p per kWh, please check with your service provider for exact unit costs.)

Optional Extras

Floor Standing Heater Guard 

A three sided sauna heater guard in a choice of top quality kiln dried spruce, or our deluxe Abachi knot free timber suitable for use with Oceanic Heavy Duty Floor Standing sauna heaters.

Dimensions: W 655 x L 559 x H 590

Heatproof Board 

The heatproof board is a strong and resilient, non-combustible gypsum board with a water repellent plaster surface. It is used to contribute to the fire resistance above the heavy duty sauna heaters.

Over time the panels surrounding the sauna heater can discolour, we use heatproof board around and above the sauna heater in all heavy duty commercial sauna cabins.
