Done everything - can't find problem

[GavThePlumber]

.....surely the issue with the feed pipe would have shown up them and ended up with the system not refilling

Mark, you have had some good advise, follow it , then get back us.

We're talking about a partial blockage in the pipework between the vent and feed connections.

 

[markyd1977]

I know the advice is good Gav, I just want to make sure I'm doing the right thing cos I need to take all the foam padding off the pipes to check it.........I've checked the pipes in the cupboard and all are good

I'd be checking boiler thermostat, all you need is a thermometer to clamp on the flow pipe.

Just been woke up with the banging again, hot water and heating were both on ......the 2 rads in the living room are cold, went to bleed them but they have water in them, the feed pipe into the tank in the cupboard next to the pump is hot, don't know if this is anything to do with overheating as all the other rads in the house are too hot to touch.....not checked the feed pipe in the loft from the header tank yet

Blr stat, you'll need a gasman to fix it, but you can check the temp with a simple thermometer, as I suggested earlier.
Turn the blr stat to its lowest setting for now, it might help.

Cheers Mick, but wat is the bir stat.....sorry

BoiLeR thermoSTAT

Ha ha, it's still too early in the morning for me......I have this at 1 already ( there are 1 -6 available). ... so am I looking at changing the thermostat stat then, the engineer I had in didn't seem to think this was the issue but to be fair, all he did was turn the speed of the pump up. Do I still need to check the feed pipe in the loft

 

[twgas]

Thermometer on flow pipe near boiler, shouldnt be hotter than about 60deg on no1.
Can't believe anyone would not check this when told of your symptoms, get a repair man who is recommended by friends, neighbours etc.

 

[markyd1977]

This guy was recommended.... I'll need to call someone out today, would the dodgey boiler thermostat cause gurgling in the fads when they first come on tho, and also the 2 living room fads not to heat up this morning

 

[twgas]

Not directly, but every time water is discharged it has to be replaced, the fresh water will drag air in with it. Once your overheat problem is sorted your air problem is likely to be so too.
You may, however, have a seperate issue with air

 

[markyd1977]

I've made the call to an engineering, let's see how it goes

 

[twgas]

Hope all goes well

I have an appointment fir Thursday but wanted to make sure it's def the thermostat that's needing fixed......heating and water have both been fine since Saturday, water started to overheat this morning so I turned it off, the heating came on 30 mins later and was ok since the heating has been on non stop since Saturday, should it not be overheating more
