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? 


     




    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. I will look properly tomorrow.


    Yes Mike, just one single phase circuit is involved. 


    Tomorrow I may just get the system working after a fashion and return to fine tune things later. My main concerns are that the property has no electricity meter and is supplied by a very long underground sub-main from next door's garage.  It used to be just one house. Also I will be looking at the main bonding and other safety related issues.


    At present all of the lighting circuits and the boiler circuit are not R.C.D. protected.
