Domestic Immersion Heater Installation Accessories

We offer a comprehensive range of accessories for the installation and control of our immersion heaters

All immersion heaters will require a gasket or ‘O’ ring, and while these are supplied with the heater kit as standard, spares or replacements will often be needed.

Most of our domestic heaters are installed in water cylinders with a pre-fitted threaded entry, but where it is necessary to fit a heater through a plain hole in a vessel wall, we offer flanges and backnuts for all common sizes.

Vertically mounted immersion heaters generally have an 86mm A/F hex flange, larger than most adjustable wrenches can accommodate, and we offer low cost spanners to aid fitting, allowing uniform tightening without distorting the head or receptacle.

Our heater timer provides a low cost means of short burst water heating, and eliminates the perennial problem of “forgetting to turn off the immersion”, thus providing dramatic savings in running costs.
