Hi All, Now that its got to the time of year that we all rely on our heating i've recently discovered that my central heating isn't working as it should. The house has only 4 radiators 1 downstairs and 3 upstairs. Yet none of them really get piping hot. Each radiator seems to have its own problem so i'm at a loss at what it could be. In bed 1 the radiator is hot at one end with a gradual decrease in temperature towards the flow end, The bath room rad is stone cold no heat at all although it used to kick out heat. Bed 2 is probably the warmest of them all with the radiator down stairs being luke warm. What could be the problem ???
Assuming everything works ok like pumps, diverter valves etc have you tried bleeding the radiators ? Has the thermostat been turned to a lower setting?
Mine is an very old floor standing Potterton Kingfisher (1981) boiler and the bleed valve was at the back near the top.
Don't think its the boiler. Just seen the pressure guage and its definately dropped nearly 1/2 bar so think i must a leak somewhere
When was the last time the system had any inhibitor?? Has it been flushed at all?? How old are the rads?? Keep the pressure low anything over 1 bar cold is too much aim for 1 bar When was the boiler last serviced and was the expansion vessel pressure checked?? Could be worth getting an heating engineer to take a look at the full system and give it all a service not just a quick boiler service
The system had a flush about 1 week ago when decorating and inhibitor was added when re filled. Have a engineer coming out in the next 2 weeks as an annual service. Just wondered if theres anything i can do in the mean time ?
Try balancing the system turn off the lockshields then open about 1/2 to 3/4 of a turn Remove any TRV heads and work the pins then replace the heads Bleed the system and check pressure if applicable Check room thermostat is clicking and that programmer is on for heating Check any valves 2 or 3 port are Woking by moving the lever on them and watch it returns fully on its own Watch plumber parts new vid on YouTube he goes through most of this
Try the same advice if that doesn't work please provide full details of your system and faults and I will try advise
