My back boiler makes a loud clunking noise when it first comes on,Sounds like a bit metal expanding with the heat being applied to it ! This only happens from cold as when the boiler has been running there is no noise at all ! Boiler was serviced just before Christmas and the guy serviced...

Hi all, I have a problem with this boiler,When the time clock is switched off the rads are still getting warm,not as hot as they would when the heating is on but they are still heating up,There has been another engineer out at it a few weeks ago and he replaced the C/H control stat,What I did...

m3/h mate

Working pressure at the boiler is 20mb,All other readings with the FGA are as per M/I specs,I was just curious too see if there was a tolerance with the gas rating,I know Valliant have a minimum and maximum on the gas rating. Cheers

Hi all, Anyone any idea if there is any tolereances with the gas rate on a Greenstar 37CDI? M/I ask for 3.9,I've gas rated twice tonight so far and I'm getting 3.4

Hi all, I have been out to have a look at my electricity meter and I was wondering if someone could clear up a few queries !! My meter has a low reading and a normal reading,next to this there is a Sangamo time control switch,Now on the Sangamo clock it has a numbers like a clockface,half...

Is there anything to be gained in using a FGA on a non condesing boiler. If there is an advantage what readings would you be looking for I.E co ppm co2 % co/co2 ratio Reagrds

Yeah good point,I'll see about that tomorrow. Cheers Mate

Superb mate,I have just switched back to natural gas,No idea who changed that then !!!! Will give FGA a try tomorrow and see what happens

Cheers guys, Anyway,went back today with a different analyser,All reading are what M/I states,turns out there must be a fault with my FGA,I have a sprint V2 ,I did notice on the top of the screen this WOOD PELLET DRY ! Any thoughts why this would be ??

Yeah I was thinking along the same lines,The only thing I did see was towards the back of M/I and it said.... When RENEWING the gas valve adjust co2 levels to 9.1% As I said the working pressure was good,gas rate good and the co/co2 percentage was 0.0006 so I passed the system today after...

Hi, I did commision the boiler today.Gas rate was perfect the only other query I did have was the C02 percentage,I had a reading of 14.3% yet the co/co2 ratio was 0.0006 which is fine !!!

What is the permissable working pressure drop between the gas meter and the inlet supply at the boiler.Is 1mb correct ??? I just installed a Valliant Ecotec plus 831,Installed 28mm copper from meter outlet right up to the 15mm connection on the Valliant and working pressure drop is 3mb ...

Excellent Tony, Your input is very much appreciated. Billy

Indeed,I do believe it is a rebadged mini, Hi Tony,I will Have to try disconecting the O/H stat,I was toiling for time this evening,Hence the reason for the just checking the basics !! I have just downloaded the manaul for this boiler,Now the leds on the front were flasing together led 2&3...

I havn't tried cleaning the fan/flue venturi,I just assumed if there was a blockage at the venturi then the boiler would also shut down in hot water mode too !!

I have been to this boiler to rectify a fault,I think this is the same as the Ideal mini C24. Anyway,The boiler will work perfectly on DHW,When asking for C/H sometimes the boiler will fire up no problem and work and other times it fires up for 30 seconds and cuts out,C/H pump seems...

Thanks for the replys guys,I offered to dig down to the drain for access and core the hole for the new 4" waste,There is around 9 meters of 4" waste,1 branch and 6 bends required aswell as 6 meteres of 40mm for the postion of the new bath,apparantly it's clay below ground so the plumber says he...

Hi all, I have just had a quote for a new bathroom being fitted and a new 4" plastic stack being installed on the outside of my house,The plumber is having to remove the existing 3" cast iron and cut the trap below ground level(he tells me there is a trap at the bottom of the C/I !!!) Now the...
