I have a Glow-worm Spacesaver boiler with a danfoss 102 programmer. I have central heating but no hot water. I have fitted a new programmer but it only runs for 10 mins then cuts out. Why?

You don't describe any other controls you may have on the system but it may be a simple gravity hw system and 1st thing to check is the small fill/expansion tank in your loft has water in it.After that things get a bit more involved.If you have motorised valves then suspect the one controlling the hot water.Describe you system in more detail.
get a fullyqualified heating engineer in an you may of saved over £50 quid on a programmer that isnt req
thanks, I checked the tank and it was only a quarter full
