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.

    yes its a combi. so you link the hw-on and permanent live in the internal plug within the boiler.

    The plumber will have installed the zone valves already, are there roomstats and controllers or programmable roomstats? It goes time first (programmer), then temperature (roomstat) then zone valve brown, then orange from zone valve to boiler switched live in the internal boiler plug
