Oil Boiler Isolation Switch.

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.

2. Frost stat installed and connected up to Grant boiler circuit board. Set at 5 deg. C.

If it is not correctly positioned and interlinked through a pipe thermostat on the boiler return pipe it might run all Winter or the boiler might shut off before the hot water has fully circulated, it just needs thinking through as it needs to open the two port valves as well to circulate through the house heating system.

It might just heat the boiler and push the hot water through the bypass without circulating through the house, if in doubt the plumber should be on top of the requirements.
