Had the Glow worm condensing boiler 18 hxi fitted by local plumbers 4 weeks ago , cost of £1562.00 , all they had to do was replace the existing boiler , fit a new pump a room thermostat , and a thermostat for the hot water tank.You see previously we could not isolate the central heating from the hot water automatically and would have to go in airing cupboard turn off the the valve manually ( summer ) or it would get unbearable even though the pump was switched off it would still travel round the radiators by confection .
Anyway we decide we want to go auto , thermostat and full control , we have them come round and fit the boiler , which was their choice recommendation , by the way we have 2 bed house with 6 radiators , 3 large and 3 small for the bedrooms and bathroom ,; they fit the thing and i am left to fathom out how it works as they have gone before i get back from work .
Here is how i perceive the boiler to be in working fashion , it has a dial on the front to set to a maximum temp of your choice , its pretty cold i set to around 75 degrees as there is a digital display , it is running very quietly at 75 degrees and the rads are heating perfectly , over the next few days it seems to be making strange noises and i can hear the water travelling around the pipes , noisy , i immediately check the rads cold at the top hot at bootom , air in system me thinks , i bleed them and were ok again , the noise has gone from the pipes , however over the next 3 weeks the boiler has been randomly switching off from the maximum and falls in temperature to around 45 and then will cut back in go past the maximum i have set it to and cut out once more .if i switch off it returns to normal and is ok for a while , the room thermostat is set to demand heat from the boiler , it hasnt reached the temperature desired of 24 degrees , the rads will be cooling down and then were off again with a few hours of correct running , and then its up and down like a yoyo , cutting in cutting out , pump has been replaced because he thought the pump was overheating and faulty , but it still doing it .
this is just a note to you plumbing guys out there to see if you have any ideas as to the fault , as we don't want to freeze over xmas as when i got up this morning it was very cold and the boiler up to its tricks.
the plumber that fitted it seems to tell me a different story every time he comes out to it , so i want to try and help him while he is doing what he can through the glow worm helpline , otherwise were screwed !
any help folks would be much appreciated
thanks dave
