ISBJØRN Ekstern - with external heater

Although our standard models have an internal heater for the best atmosphere and quick heating (within 2 hours) they can be supplied as well with an external heater as well.  

External heaters have some practical advantages like easy cleaning (no narrow spaces in your hot tub, easy removal of ashes) and they offer more space in your Hot Tub.

Generally we can supply 3 different types of external heaters :

  1. 30 kW external aluminium heater (silver colour with black frontside);
  2. 40 kW external aluminium heater (with complete black coating outside);
  3. 40 kW external cylindric shaped heater (with black coated frontside, further coating on request).
