    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Hi Tony, Credit where credit is due in my opinion. I'm not sure of the total length of piping used, but it is quite a length as the meter and boiler are at opposite corners of the house ... possibly 18m in total length (only a guess though). The garage length is around 3m of this. I...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Guys, I wanted to thank you all for your very helpful comments and advice. When CORGI refer to 'competent' engineers I'm sure they are referring to people like yourselves. If any of you feel I should be looking to change my pipework in the short, medium, long term then please say so and I'll...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thank you very much for your contribution. It certainly helps to convince me that any work required to my pipework can be delayed until the summer (even if it is needed) and that I should be looking for someone much more competent to service my boiler. A.

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Hey Tony, Thanks again for your very helpful advice. I checked the hob as you suggested and I could hardly notice the difference in the flame when turning the hot water on/off. I tried it about 10 times and in all honesty there was probably only one time out of that where I noticed any...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thanks swbjackson. Fortunately the over is an electric convection oven, so it's only the hob where there is a flame. In addition to that my wife tends to burn all our food anyway!! :D

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thank you Mickyg. Very useful information, which at least I don't need to sort out very quickly. I may leave it until the summer to sort out then. Given the point you've made about the 2.5mb drop because of the 'issue' with the ecotec models, then I'm probably getting 21.5mb at the gas...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thank you Tony. Your reply was very helpful and helps me to understand much more what the regulations stipulate. It seems that I've come across two completely independent engineers that have combined together to leave me with a little dilema about what I do next with my pipework. It seems...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thanks boacelt. I had been told this by the servicing engineer, but he also explained that this is somewhat an unrealistic regulation and is rarely achieved when there is a great distance between meter and boiler - even with 28mm pipework. Only repeating what he said, but yes you are...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    Thanks very much for your reply Agile. You're right I'm not asking a direct question, but I wanted to post this to help anyone else out in a similar situation. I hadn't realised that this site is purely there to ask technical questions. All I wanted to do was pass on my knowledge and story to...

    Vaillant 837 Ecotec. Gas Inlet Pressure Problems

    I've had some issues with inlet pressure and have gone through a steep learning curve to understand what pressures are required at the boiler. I'm no engineer, but I have used this site to understand more about the requirements before I undertook expensive and inconvenient work. I have a...
