My Combi Boiler (EuroCombi Ariston) keeps turning the rads on even thou it is only set to water. I did have the water set to continuas but have now changed it to normal. I had it on continuos cause it seemed to warm the water quicker. It has happened twice now and would like to know a) is this a issue or b) something I have been doing wrong?
Would appricate some guidence and I know diddle squat about boilers!
