Small Water Element (1” or 1 ¼” boss)

We stock a limited range of small water elements in the following Ohm ratings that have many applications in DIY projects on 12/24/48 and higher DC battery systems.

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.

Power (W)

Ohms	14V	28V	56V
0.8	245	980	n/a
1.5	131	523	n/a
9	22	87	348
28	7	28	112

 

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
