Surejust low wattage SOLAR and MARINE immersion heaters have been designed over many years specifically for use in the harshest of environments.

  • Each immersion has a high quality heavy duty 20amp working thermostat.
  • An independent secondary safety stat that is set at a much higher temperature so the engine doesn’t trip the stat unnecessarily. This would happen with a standard domestic immersion.

  • 110-volt immersions available
  • 3 phase available in various sizes.
