All elements have 1” BSP/NPT threads on the element and we also supply a brass adaptor for 1 ¼” BSP threads.

Ohms ratings as per table below, do not use above 1000W or 120 VDC.

On DC water elements good practice is to ensure:

  • Termination points are tight
  • No insulation or combustible material near element connections
  • Terminal cover is metal to reduce any fire risk from an arching connections
  • Check all dc connections annually for any sign of heat damage & rectify
  • Ensure element has water cover at all times
  • Clearly label how element is to be turned off 
  • Comply with local wiring rules
