boiler kettling?

[mac1]

Just fitted a new ideal boiler to an old system.Flushed it through. It seems to be making a loud drumming noise continuously and also lots of air in rads which keep coming back.Otherwise all rads are heating well.any ideas asap!!!help

Without even knowing the boiloer model its difficult to guess anything but dirt sounds like a prime suspect.

Did you powerflush the system and add the right chemicals?

yes it was power flushed though the system did run without being flushed for a few hours. the boiler is an ideal classic HE18.Should I add a chemical that quietens it.i saw one called fernox. Or is it more major. Does it sound irrepairable?thanks for quick reply

A boiler silencer is used to clean the heat exchanger of scale and dirt that results in kettling (lack of heat adequate heat transfer)and as this is a new boiler then i presume that it is not scaled up etc so i'm not sure that a boiler silencer will make any differance though i may be wrong?

bster... thats restorer... but then i dont know how silenser works...

 

[bster]

i though silencer was basically to clean the heatX and restorer was marketed as a flushing agent for the entire system? they are brobably the same thing in different packaging though

sonds like scale deposits in your heatX. happend to me over the weekend when i dropped my system to renew pipes upstairs, it disturbs deposits in pipes and gets stuck in heat x. get sentinal deposit remover, pour it into the closest radiator to boiler, close all rest of valves, and run on low temp for 30min, or till noise stops. MAKE SURE YOU THOROUGHLY FLUSH ALL THE CHEMICAL AWAY! as this will cause gassing up and youll have more problems. it bout 40quid for big bottle of it. you only need bout 2 pints of it, so slip an engineer a tenna and get some off him.

hope this helps dood!

nah silencer goes in after flushing... i like to think it fills the pits left after removeing debris from the heat ex. ie it stops the water from eddying inside the hex and kettling.

but i could be wrong

Think I will leave it to an engineer. It all sounds too complicated. Thanks for the advice here.Sounds like a good idea.

Thanks for all the advice re kettling boiler.Great stuff.

I think you are right there.

Hi everyone. After having the boiler flushed twice it is stil kettling two years later. The boiler is new but the rads were old.
Is it dangerous.

Fitting an ideal is dangerous to your health, got to be the most ironic name on the market, as they are anything but

I didnt understand your reply.

did you ever get an rgi in to inspect? see many problems on low water content heat exchangers fitted to old open vent systems where pipework is not suitable owing to feed/expansion and pump orientation not being suitable.

If it was this I suspect water would be so full of sludge etc it would no longer work
