air trapped in boiler circuit

[kris]

Clearance distances to the boiler. That's what you call boxed in. Does casing even come off with the wood on the top.

on a side note is there a way I can check this has been registered with building control? I assume he was supposed too.

 

[cypher007]

if I manually open both dhw and central heating valves then run the pump without the boiler running for say 24hrs, do you think I might be able to shift the air pocket?

 

[Ermintrude]

Who's cut out the air separator and the pump and capped the cold feed. Yes it's dangerous ! Bloody idiots. . Was it your muffin who did the work above boiler? Get the pleb back.

Is the engineer gas safe registered?
The 4 pipes coming off the boiler, come from different heights from the heat exchanger,
Step 1 is to get air valves put on those pipes instead of caps. These caps are incorrect!!
step 2 Leave the hot water on overnight, (do not jam the hot water valve on as this could be dangerous), just leave it on at the programmer and use as much hot water as possible!!
step 3 get engineer back to replace the PRV pipework (D1) as this is wrong and other errors in pipwork

finally had time to take a pic, excuse the pipe insulation that's my effort at lagging it all, basically if it gets warm I lag it:

What a mess the installer is a muppet. The boiler shouldn't be left looking like that but the unvented shouldn't be installed like that. It's a requirement that all pipe work. E lagged 1m from boiler. The d1 is well over spec.

Wiring looks nice and tight on your ch 2 port. And the pump. Nice postion. Well throughout job generally!

Boiler looks like it was once 4 pipe pumped heating and grav hw. Now they've altered to 2 pipe fully pumped ( I think) but does look a bit of a shambles. Would need to trace pipes to determine what's what.

 

[kris]

All that tight 90 degree bends are crazy.

 

[cypher007]

you are correct sir, collect 200 and pass go.

I was a grav hw and pumped central heating. they moved the pump from above the boiler to the hw tank cupboard. the 15's above the boiler are actually part of the central heating circuit.

 

[cypher007]

the prv do you mean the crazy valve above the cylinder stat and valve? and how should it look?

p.s. after talking on the phone I don't think he will be very receptive to doing loads of remedial work. what ive found since moving to lincs is theres the correct way and the lincs way. hence when I had solar panels fitted I had a company from Leeds do it. its also why I have a Polish mechanic service my car.

 

[cypher007]

just a thought the dead legs above the boiler, do they goto the same channels inside the heat exchanger as the others? please tell me there not separate chambers and im sitting on a pressure cooker.

 

[cypher007]

also this tank is fed from a 15mm cold feed, is this ok?

 

[stevetheplumber]

could have cut the old pipework back a bit closer to the boiler but when this boiler was fitted it was allowed to cap of two of the connections depending on weather it was gravity or fully pumped the other caps are sealing the heating circuits
boiler was ncs from the day it was fitted due to floor clearances and the wood frame above is also ncs for clearance
two side to every story ive no doubt they suggested a new boiler but if the customer was saying we will upgrade the boiler soon it may have been looked on as a temporary fix
case slides straight fowards on that boiler so in all probability it does come off
ive not got unvented so cant comment on cylinder

 

[cypher007]

whats d1 is there a site I can look at? if the prv is the one near the top of the tank, it was supplied already in place, but when the tank was filled it started dripping. so they turned the valve body to tighten it up.

 

[Ermintrude]

They........ Not you then?

You need a g3 and gsr.
