Hello,
For oil fired boilers, please can someone clarify what firevalves are required? I've done a google and apparently they are specified in BS xxx. It seems British standards are not available online and I am expected to pay £148 to find out what this particular one says! What's the point having standards if they are kept secret?
My old boiler had a firevalve that looked very much like an isolating valve inside the casing. I see these are still for sale in the catalogues. Are they still used? I thought practice now was for the sensor to be inside but the valve to be outside the property. I see these valves have two temperatures: sixty-something C and 90C. Am I right to thing the 90 degree one is for Agas and that a boiler requires the sixty-odd degree one?
Thanks, Stephen.
