Hi I have been fitting vaillant 831 ecotec plus boilers for years now and have had no problem getting the gas rate required by always running 22mm gas pipe right to the boiler. I have done a couple of ferrolli 31kw boiler and have struggled to get the right gas rates? I am going to have to up...

Hi I have used this forum a few time and everytime i have been given helpful advice. This job can be a can of worms so getting advice from the people in the frontline is fantastic Thanks again!

okay I will check the supplies it was the sparky who wired it so don't know myself at the moment. Cheers Will let you know how i get on:)

Ahh...the temp that makes sense.I can't remember what it does when reset i will check out tomorow . It seems to just sit there showing the temp Don't think it is asking for heat even though the motorised valves are coming on thanks

its not firing up at all, must be air I will keep reseting it tomorow to see It's on a programmer. If the programmer calls for heat and the motorised valves come on does this mean the boiler should activate or could there be something wrong with the wiring? Thanks for help

Yes i have reset it about 10 times and aired the pump. Can't see the fault code on the manual Every time i rest i can hear a little air at the boiler maybe i should just keep reseting?

Hi I have just finished installing a keston c55 gravity fed boiler. When i turn it on it starts to release air then a 0 19 code comes up and it does nothing. The pump turns on but no ignition then nothing Any experience with these boilers? Cheers

you can only use plastic on some boilers. Vaillant say you can do it with thirs because it has some kind of limit stat, copper heat exchanger. Polypipe and speedfit stat you can use the plastic if it is 350mm from heat exchanger

It is a BS 7291/PT1/PT3 (British standard) to take 1m of copper from boiler connection Who has the last word? Manufacturers, corgi or british standards?

Well it has always been the case that corgi specify what is right and wrong...or we are lead to belief this. I know people that have had to go back and change plastic pipes on the vaillant because corgi say it is wrong. I did a vaillant a while back in plastic and am a bit worried that...

What if corgi say its incorrect when its installed in plastic?

I spoke with one of the vaillant technical advisors on the phone and he said you can come straight of the boiler connections in plastic pipe? Has anyone else been told this?

Hi i am thinking about taking out a ideal concorde cx boiler and installing a keston c55 in its place. Could anybody see any problems with this? has anyone installed a keston before? Thanks
