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.

    Downstairs there is a programmable room stat but the tenant wants just a simple rotary room stat as he finds the digital programmable one too confusing.  Upstairs is a mystery as I have not had a chance to view it yet as the boiler installers were in the way and I wanted to look quietly on my own. I may just have a simple single channel programmer for the space heating. Hot water permanently on. Upstairs and downstairs each with separate room stats


    See table 12 here

    Time and temperature controls required for each heating circuit, circuit defined as being controlled by a zone valve. UFH needs longer heat up times so a separate timer from any radiator system upstairs would make sense anyway.
