Cold Radiators

[SimonG]

Boiler underpowered is rubbish and is one of the first things I check when installing additional rads. Your response to this should have been to say that you had turned all the other rads off so it was only running the additional ones. Good luck for next week.

Thanks SimonG...

No plumber worth his salt add radiators to a system that would render the boiler under size, there is no more to be said, I will be there next week to have a look Jules

[SimonG]

No plumber worth his salt would fit extra rads and leave them not working imho

100000 Btu is 29KW. So by his own admission and dodgy calculation the boiler is more than ok.
:hurray:

don't tell him that his head will explode lol

...I think I already have...oh dear...:hurray:

Bet his come off a return from a rad which he thought was a flow (Some people think that because it has a TRV on it its going to be a flow, which is not always the case) , and tied what he thought was a return into a return to pick up for his new circuit (If you get the jist) wont work unless the rad his come off is working/trv open etc. I've seen that before with people not knowing what their doing. Its a proper head scratcher when you come up against it as you eyes miss it the first few times because your mind and skill tells you No he wouldnt of done that. My picture I drew up quickly might make it clearer.

 

[lucolivia]

Thank you for the drawing.... If we turn off all the other radiators after an hour or so the temperamental rad becomes barely luke warm...would your suggestion still apply? 😉

 

[PriestyUK]

Yes as a TRV may still pass when screwed right down. Without having a 2nd beady eye on what this guy has done you may never know as he could just keep trying to pull the wool over your eyes 🙁

Me thinks it's not that daft, there are 5 rads not getting hot, that means he's done it five times, he would then be the real plumber from hell, too much speculation going on an not enough facts, I will sort it out next week chaps and I will report back, it will not be just one thing wrong. leave this one alone now and I will be back.

Make sure there is not a uncontrolled by pass

SafeGasInstaller,

I have a bit of kit that sits on the pipe and measure the flow inside, I will spot the uncontrolled or controlled bypass in a flash, I don't want to worry about me either, I have been in the trade for the 55 years and as long as the Good Lord doesn't take me in my sleep before I go to site next week, I will sort the plumber from hell out, be assured, trust me I am a real plumber!!!:35:

BTW I have heard they are going to officially make plumbing a trade next week :lol:

Anyway do any of you know when plastic tube was first used for minibore central heating???

Have you been back yet Happyflyer? If not when?

Just to chuck my 2 pennies piece. When that plumber left did he jump in a van or ride off into the sunset!!!!

Me as done, put the old trusty test kit on and found the water flow was too low, lots of other things need to be put right boiler in the roof space, with two zone valves pipe to valves go up higher than boiler so boiler is not the highest part of the system so auto air vent in boiler not much use, got plumber back, programmed boiler to run pump at full speed, twas only running at half, closed down ABV and got water flow up to boiler recommended rate, all rads now (WOW) get hot except on on new index circuit, balancing now tight, main F/R in roof space rises up to where it drops down to Ist floor needs 2 AAV and pipe cutting shorter, needs two AAV on boiler end zone valve branches, you need to remember that the Valliant like others don't have a big pump on 20 Kpa this is not very much for long runs of 15 mm tube, If I was fitting a boiler which feeds heating and a Magaflow I would use a basic boiler without pump, you can then change the pump if you drop a clanger.

Tony

PS the plumber who did the job now calls me Dad and I will take him under my wing from now on, why because he listened, the day you stop learning is the day you die and that includes me.

Rock on Tommy

 

[tommydiehard]

Fair play to him for not getting his back up.

I'm impressed too.

Whats the test kit? Sounds like a nice toy to play with.

I've never thought about fitting a boiler with out a pump. Every day is a school day and I've just learnt something.
