Oil Boiler Isolation Switch.

Zoomup
Evenin' All,


Regarding an external ground sited domestic oil fired boiler for heating and hot water that has an internal switched fused connection unit nearby inside the house, what regulations will require an external electrical isolator adjacent to the oil boiler? You know the sort of thing, a double pole rotary isolator.

    S-plan with two port valves that have the required relays built into them and a three channel programmer.

    Thanks Andy. Will the valves have relays or micro switches built into them? As the boiler is a combi boiler can the hot water side just be left on a permanent mains supply with no timer/programmer, as the boiler will fire up when it detects a water pressure reduction as a tap opens?

    Although it is a combi there is probably provision to preheat the boiler and hot water at predetermined times to make it less wasteful of water and the users time by avoiding running water to waste whilst it warms up.
