Hello All Engineer has been, fitted lo stat and overrun stat and serviced boiler. All seems ok now. Only a few hrs so not too bad cost. Thanks all for your help. JackRussell99

Thank all for your help, will get engineer to fit stats as soon as poss. Will let you know what happens.

Many thanks for your wisdom. I will see if I can combine a service wth fitting the stats. One last thing should the bypass be closed some and how much?

if its the thermostats is it expensive?

I should have said, the bypass opened by me in an attempt to get more hot water. It seemed to be overheating without rads on, pump straining when water very hot. Just tried pump on 3. It lasted about 1 hr 20 mins before I switched off to prevent it venting over again. Every thing really hot...

Problem started after having TRVs fitted as part of efficiency grant. Fitters not that interested in problem. Bypass is 15mm pipe with manual valve, this is wide open. Pump on speed setting 2.

Yes they are hot.

Boiler runs ok for 15 mins if heating hot water but longer if just rads on, approx 1hr, then cuts out. Tried reading through some of the prev threads but not sure if the same faults. Boiler is Apollo, not sure of type. System looks like S plan - open tank for feed and vent, 2 x 2 port...
