I have an indirect system using a Baxi Solo 60Rs boiler. My problem is that when heating water only the boiler ignites but shuts off after about 1-2 mins. It will reignite again about 5 mins later but again only for a minute or so. Consequently I cannot get enough hot water from the taps, in fact barely any.
If, however I start the CH this has no problem and the boiler will stay on and the rads are supplied no problem.
I actually have two zone valves, one for the water and one for the CH. The motorised valve head for the water zone valve was replaced about 4 years ago - can they go faulty in that time?
How can I check that it is definately the valve faulty before I buy one. Can they be overridden? What is the little lever on the head for?
