hi hope you can help,i have got hot water but no heating,boiler fires up ok but cuts out after about 10 seconds but pump keeps running, have had a new pressure differential fitted as the old one was leaking and the plumber who fitted it could not anything wrong with boiler ,but does seem noisey now,pressure is ok at 1.5 but have got drip from overflow thanks

Is the central heating thermistor ok? And the leaking overflow, do you mean the PRV?

Boilers dont have an overflow!

Even a cistern has a "warning pipe" now!

Might be wrong but you may have had a bad guy work on your boiler!
My hunch is he

• - changed the diaphragm hoping it would work,
  - charged you for a whole pressure differential assembly it didn't need,
  - failed to notice that the hot water flow switch is stuck on which would give you exactly the fault you describe, and while he was at it,
  - drained the boiler for no reason whatever except ignorance,
  - through the pressure relief valve which he shouldn't have done!

Now you need someone who knows what he's doing, to change the flow switch and the pr rel valve!

hi thanks for your reply to my prob, would the hot water flow switch be a little red button with 2 wires on it on a copper pipe as this wont move at all when pressed. once again thanks for all the help
