Convection hot water not working

[Mike Jackson]

Re piping in copper may get it to work but as mentioned above the cylinder isn't a gravity cylinder so no guarantee.

The pipe coming from the wall with the 90degree bend in! On the top of this pipe fit an air bleed valve might help they're about 90p-£5. If you say there were no hot water after doing the task and it was okay before and you've not touched controls

have you changed cyl thermostat>? maybe wired up wrong

Try turning the cylinder stat right down.. If boiler fires up you've got rires wound long way.. Obviously the common stays and grey and black switch over. And don't forget to turn the power off first...:skull:

Simple. Change the cylinder for a gravity rated one. Use correct diameter pipe and fittings. Job done.

Ps and get a plumber in as you are messing about with things you have no idea about
Flexis are for taps not a heating coil

Nothing wrong with the cylinder its indirect???

please rotate your head by 90 degrees

wtf !!

 

[glenno1]

Change flexis and installer

But it's a high efficiency one not designed for use on gravity primaries.the resistance of the coil can be too much to allow gravity circulation to take place.

id stick an old shower pump on the flexis
make a proper bodge

The stat looks new ,, where's triff gone too

 

[jase158]

But seriously, turn boiler off, do not use and get it replaced in hard copper, at least it will be safe

That is undoubtedly the worst cylinder pipe work I have ever seen.

 

[jtsplumbing]

Whoever told him to do it like that ? what a disaster , thought he was saving money , now he needs a suitable cylinder and correct pipe work, or change it to fully pumped system, whatever he decides he is better off getting someone in to sort it out, makes you wonder what else he has done !!

 

[lame plumber]

Please try and be a little bit constructive with your answers guys.

Difficult I know, but..........

we were ok till post 13 onwards:

what you on about ......there is not any pipe work its just flexis

Thought it was pumped primary!?!?!?!?...

Not what the title of the thread says!

Okokokokokokokokok my assumptions..and I'm wrong.. Actually think I'll do a runner before I see it gets any worse round ere.. Hehee
