Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Do you have a radiator key?? ~ Ian
OK we need to reduce the pressure to about 1.6bar, if you have a couple of towels and the key we can reduce the pressure by releasing some of the pressure by bleeding it off by at the radiator bleed screw, its a case of bleeding off a short period of time and then shutting it tight whilst you recheck the pressure.
Yes just turn the heating off for a short while whilst we are doing this,
Have you had the boiler on all day ?
OK leave it at 3bar for the time and recheck in the morning. If you understand, you can start the day at 1bar but as the boiler increases the temperature at the radiators so the pressure also goes up. Recheck in the morning and come back on here and we can then decide if further action is needed ~ Ian
OK that's fine if you can bleed a little bit more during the day and get it back down to just over 2 bar in the morning you should be OK, the unit is fitted with a safety vent that will relieve the pressure if it gets too high but static pressure (ie not running) should be between 1 - 2 bar. I'm sure it has more to do with you running it constantly to keep the baby warm than a fault. If you have any more queries come back to me. Would you now kindly rate my service using the Smiley faces below, this allows me to shut the job down on the system but allows you to continue to ask questions free of charge. I am travelling to London from Boston in about an hour but will ask my college George to keep an eye on the question and once I am in London will come back on a check how you are doing. Just in case ~ have a Happy New Year ~~ Ian
