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.

    Okay, I have actually had a look at the boiler installation instructions linked to above.


    The boiler has a 32 litre primary heat store with a circulating pump, the boiler will be hot and cycling 24/7 without a hot water timer and being always on, it needs a hot water timer.

    Is it not better just for the boiler to "top up" the heat in the 32 litres store of hot water rather than heat up from cold every time a hot tap is opened?  Surely that is why a hot water storage tank is included in the boiler. And what happens if there is a need, say in the middle of the night, for hot water if the hot water timer if off?
