ive removed 2 radiators from our combi boiler system and have no heat to any of the radiators and when i try and bleed the upstairs rads i get no air and no water......... boiler pressure is 2.5 bar. do you reckon its an airlock and if so whats the best way of removing it given bleeding the rads is having no effect?
thanks
Check the boiler isolation valves are open. They may have been turned off when the system drained.thanks

We have a non vented hot water system and gas fired central heating.
Recently despite both water and heating being set to Off in Nest the boiler fires up and the radiators get hot for a short period?
The times seem to be random.
Why would it be doing that?
Check that the setback/eco setting isn't too high on the nest. Try setting it to 10 degrees and see if that sorts it.Recently despite both water and heating being set to Off in Nest the boiler fires up and the radiators get hot for a short period?

I'm thinking of getting hive or nest x2. One for upstairs, one for downstairs
Downstairs will be a reception room, an open plan kitchen, living, dining room, one en suite guest room and a WC.
Upstairs are three double bedrooms one of which is en suite and a family bathroom.
Is one thermostat upstairs and one downstairs okay?
House will mostly be empty during the day Monday to Friday.
Where best to place the thermostats?

Why is the pump running constantly on my woscester Bosch combi even when no heating or hw was been called for for ages.
I think it does that until the water temp in the pipework drops below a certain level which can take a certain amount of timeI'm sure the plumber will be along in a week or 2, several unanswered calls and 2 agreed times/dates he would turn up but failed, to correct me or explain why it happens

Do you mean it runs for many hours with no demand - if so, what kind of controller does it have?One of our daughters has the Worcester Wave controller and that has a mode where the pump runs all the time, IIRC with an option to shut it off overnight. I think other types of weather compensation controls do the same thing.

We live in a 60's house and the hot water pressure seems very poor, at least compared to the new build we moved from.
We have an electric shower which I am told is because the hot water pressure is not enough to have a mixer.
If I run the hot water downstairs in the kitchen, it takes 60-90 seconds to actually get any hot water through and even then its not anything resembling decent pressure, similar case for the bathroom tap.
Is there anything we can do without spending a fortune?
Edit - Its open vented. Boiler is about 6 months old so fairly new. Obviously pipework is old, 15mm diameter.

What's the rough percentage of open flue systems still in use?
Only asking as we had a plumber come round to service ours last week, who took one look, laughed and said "I don't service them" (closely followed by the 'buy a new boiler' sales pitch).
Yes it's old, but simple in operation and works so why bother replacing!

I believe the logic is you spend thousands replacing it with a snazzy new boiler, save 5% on your gas usage but then buy another one in ten years because they don't last as they are "built to close tolerances to make them very efficient".Only asking as we had a plumber come round to service ours last week, who took one look, laughed and said "I don't service them" (closely followed by the 'buy a new boiler' sales pitch).

Which is exactly why I don't want to replace the existing one, making the switch would not generate savings in efficiency to cover the cost.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
