Just had a new outside (Worcester Camray 18/25) oil boiler installed that replaced an internal boiler.
I am slightly concerned by how it is wired for frost protection.
The exisiting frost and pipe stat are wired as they were before, inside the utility room and if it gets cold enough, they fire up the boiler. No problem here, apart from the fact, that the boiler has no constant power to it so is not using/ benefitting from its own built in frost thermostat....
So, if the CH/HW is off, and the house is say 7 degrees inside and its below freezing outside, then the boiler is not going to fire up?
I mentioned this to the installer and he said that the boiler housing is VERY well insulated and it won't be a problem?
My question is basically, should the boiler have a constant live to it and rely on its own frost stat?
I thought one way of sorting this would be to turn up the inside frost thermostat and wire it in series to the boiler... then, if the temperature inside drops, the frost thermostat to the boiler will come into operation?
Or will it not work like this?
All advice/ help appreciated.
Thanks.
