Ideal Boiler

[Old Boiler]

Hi, wonder if anyone can help. I have an Ideal Isar boiler and tonight noticed it's making a weird noise - please dont all suck ya teeth and say *ooooh that sounds expensive*!!!! lol It's not showing an error code, doesnt make the noise during heating water it only makes it when the central heating is running. It's a regular noise and actually sounds like a loud *sigh*. Both heating and hot water are working at the moment and it still does the *t* thingy. Can ya tell im hot at this plumbing lark!! Any help much appreciated.

no swearing allowed on these forums.
hope that helps?

 

[Old Boiler]

thanks for taking the time to point that out.
Any help on my actual question would be much appreciated too

describing sounds, tastes or smells is always a tricky task as is deciphering someone else's description but I'll have a stab at helping with your question...you say the sound is only evident when the boiler is in heating mode, are there any other annomolies i.e. are all the radiators hot downstairs as well as upstairs (assuming it's a house)? Could the 'sighing' sound also be described as a whirring sound?

 

[Old Boiler]

Thanks for your reply, yes the noise could better be described as a whirring - all the radiators feel hot, upstairs and down.

without actually hearing it myself it'd be hard to give a totally accurate prognosis but it may very possibly be the pump, if the downstairs rads were cold but the upstairs were still hot then this would be certain confirmation. There is another possible cause which could be air in the system, have you vented all the rads lately?

 

[Old Boiler]

My other half used to do all that sort of thing so I've never done it before but I did check to see if the radiators were hot top to bottom and they were. What ever the problem is I'll have to get an engineer in cos I'm clueless, if it is the pump are they easy to get hold of and would it be an expensive job??

 

[shorticus]

the pump would be around the £100-£120 mark, as for fitting that really depends on the area you live in, the condition of the boiler isolating valves and ease of access to the boiler. As I previously said though this is only a 'possible' cause, the boiler really needs to be seen by a technician to ascertain the problem.
Hope you get it sorted, let us know hoe you get on.

Check system presure is not to low could just be as simple as topping up to 1.5 bar

 

[Old Boiler]

thank you both for your help - I'll top it up a bit and take it from there

Hi Old Boiler

Isars often sigh, it's in their nature! I think they want to be noticed, some inferiority complex, that's why they are always taking the huff and stopping working!

Best bet is as you say, get someone in to hear the noise and better diagnose it's cause!

Usual faults on the isar are internal flue seal moving and blocked condensate trap (the black internal one).

Well your membership has been deleted as requested. You have an ideal isar though so your smugness will be short lived.
I hope everyoner has learned something though...
