Our oil central heating system has the boiler outside inside a small purpose made unit, there is a frost stat fitted inside the unit.
Am i right to think that the frost stat is supposed to turn on the boiler so that it does not freeze in the winter, but it never seems to work.
How can i check this to see if there is power going to it or check to see if the stat is faulty.
Any help would be great.
