Oil Boiler Isolation Switch.

That won't comply with the Building Regulations and isn't necessarily doing the user any favours.


The old rotary clocks only time to the nearest quarter of an hour resulting in hours of heating that is not required, also they will not be able to set a set back temperature so you will need to consider installing frost thermostats with protect their heating systems and homes creating more work and expense.

 

Obviously the outdoor boiler should have a frost stat in it anyway, so if it doesn't freeze up unless the weather is so extreme the heating oil waxes up and freezes. Heating oil should be okay most winters, there used to be farmers who has diesel boilers so they could run a pipe off the back of the tractor fuel tank to use fuel claimed as a business expense for heating their homes, but diesel freezes before heating oil so there's a greater risk of frost damage. Back in the 70's I repaired thirty seven frost damaged pipes in one farm house after the diesel froze.
