Hi there

Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
It seems to trigger the F28 on the central heating demand for the radiators. As it was a very mild day yesterday the only zone active in the house was our bedroom as it’s set to 20’c as there is a new born in the house.
Then please pm your details to @Riley @ShaunCorbs or @Harvest Fields and we can arrange for you to gain your gsr tag and access to gas safe only area. Until you have it then please be wary on commenting on gas issues as our members need to know that we talk gas safety very seriously. Keep posting, introduce yourself hang around. Very nice to have youBy the way I’m a gas engineer
Not withstanding the F28, it would appear you have a you have 2 oversized boilers on a poorly designed system, I take it from the single large pump that there is no low loss header installed? (60kW through 28mm what were they thinking !!!)
Why haven't you gone back to the installer / manufacturer before now?
When you go down to reset, is it both that show the F28 ??
There’s pretty much always ways. It just needs careful planning and designI agree with you on the Low Loss header installation but regarding the single large pump and the 28 mm pipes what could they have done if the pipe installation was there and it was not possible to amend the pipe work as for example its all within the house without them being able to rip the flooring up and and install smaller pumps for each area/floor.
What would you have done differently?
Thanks in advance
Would very much appreciate your ideas.There’s pretty much always ways. It just needs careful planning and design
I agree its hard to generalise.Depends on space, where pipes become accessible, is there a basement, can zones be set up differently. Too many variables to give a one size fits all response
Not really help but seen something like that in a job by a quite experienced GSR engineer and and as i am new gas safe ☺️ was trying to see what options could be done as honestly I thoroughly searched for ideas couldn’t find a way other than wt the other gas safe engineer done.Mate it’s too vague. You go there you plan you discuss with the client the benefits of the install you propose and you work together towards a sensible solution. Are you looking for help with an install??
It was a year course, I qualified almost 18 months ago but the job i was talking about was new to me. And unfortunately it was few months ago and didn’t took pictures at that time.Need to see the job mate. Do you have a mentor??? College tutor or something?? Did you do a short course
I do totally agree Riley.That’s kind of the point though mate you do a full apprenticeship so you learn how to size systems and design systems and understand the different ways to make one work. College tutors may not be pushing the most up to date technology but what they will push is solid ground work so that you can sit down with a pencil and paper and correctly size and specify a system. If you have the spec of a larger property then some companies will design it for you. The lectures and books as you call it are the groundwork’s knowledge wise to how to do our job properly. Do you ever make reference to your gas regs when out on the job. You should no one knows it all. It’s the same principle. If you are in anyway not confident with this larger job then turn it down as it will come back and bite you this I guarantee. Also your comment about working round things. Sometimes the customer just needs to be told the correct way to do it and they have to accept it or you need to walk
Some do, or at least we try.College tutors may not be pushing the most up to date technology
It is not so much a dilemma Abuali, it is simple a challenge after all you can only do what you can do with what is in front of you. The knack I guess is to do your best & then set out the limitations as you see them but backing it up with just as much “pen and paper” work as you might on a new project.The dilemma I personally find is most of the jobs esp bigger houses most of the times i see engineers have to take over from what had been done, work on old pipe installations so not as easy as new system where you can completely design it from the scratch depending on the therotical and “pen and paper” way.
Now I am not on site, if I were I could go measure all of the above & work out the heating load (or even do full heat calc's) but as I not I could apply some experience - such as rads tend to average out at around 1.5kW in older houses so around 25.5 for the rads + U/F tend to require around 100 W/M2 so around 15kW's giving a total max heating load of 40.5kW (at -1 or -3 out side temp) so why install 60kW boiler power ??150sqm downstairs, upstairs is 13 rads and 4 towel rads
Absolutely no offence taken Riley!! 😎Brilliant explanation Chris. No offence meant by the college tutors thing. Mine were brilliant and were very much up to speed, sorry the op seemed to imply his weren’t quite so
The only thing you have to maintain is the 1mb drop accross the installation pipe work..
Could this scenario some how cause the boiler has supply issue as it’s just ignites and then switches off due to the demand not being required anymore?
I’m mechanically competent and used to restore classic cars. If you start a car but switch it off without it fully turning over it sometimes results in it flooding and difficult to start the next time. In very layman terms could this happen with gas?
