I have recently replaced a copper cylinder with stainless steel cylinder. I have also, at the same time, replaced a single element immersion heater with a dual element. (Sink/bath) suitable for a stainless tank. Both tanks are the same size, both vented, both insulated, and both fitted with an...

I have recently installed an immersion heater with dual heating elements; controlled by a sink/bath switch. It is likely that only the short heating element will be in use over a fairly long period of time (six months?). The bottom three quarters of the tank never heats up. The cold water inflow...

I have read, with interest, some previous posts on this subject. This prompts me to ask if anyone could give me a brief description of how these units work? Does the current being drawn have to go through the unit or does it sense the quantity indirectly (maybe strength of field generated)? In...

I have installed a sink/bath immersion heater. The combined rating of the two elements is 5.5KW; drawing, perhaps, 22 amps. The standard, and readily available, sink/bath switch is rated at 20A. Does anyone know of a source of sink/bath switches with an higher rating? I realise that I may have...
