trv on cylinder!

[barryplumb]

Hi everyone, had a call for a leaking cylinder yesterday, when I looked sure enough it was leaking from the return connection.
The cylinder is very old and not a problem to change.
My only concern is, on the flow pipe into the cylinder coil there is a trv which is connected to a chrome, torpedo shaped cylinder stat by a small trace wire.
If I change the cylinder I need to upgrade this to a normal cylinder stat, but with no control box apart from the old type ( on until A , blue and red type of thing), where can I wire in the new stat?
Any advice would be great.
Thanks

they are a meachnical shut off valve, like u say a trv for a cylinder. i think minimal practice will allow u to replace, maybe someone can confirm

May be wrong but im pretty sure that these tap stats dont comply with current reg-so by rites its a case of upgrading to y or s-plan as well as bypass valve , cylinder is probably old and inefficient.

Thanks guys, already suggested to customer about upgrading whole system so hope fully they'll go ahead.
I will double check if the old stat coplies to regs.

Thanks again

Don't think the old stat does comply but would work in the mean time, with a recommendation to customer that the system will require updating.

I thought that you were suppose to fit those tap sats to gravity cylinders when changing the cylinder if the customer does not want to convert to fully pumped as per part L??

If they dont want to pay for the upgrade to fully pumped then it was mandatory to fit tapstat to comply ???

Or is that just BG brainwashing me to make upgrade sales

 

[fuzzy]

i dont see how u can force an upgrade, what if they cannot afford it? hence minimum upgrade options

anybody tell me where it says on a cylinder change you must put on valves etc, part L if I'm right didnt mention changes.

 

[stevetheplumber]

if the boiler has no overheat stat the cylinder has to have aresetable stat fitted which realy means youll have to update controls

 

[stani]

surely the resetable stat is on the immersion

 

[prs1]

who said its got an immersion?

 

[stani]

sorry, what i should have asked is, where would the resetable stat be on the cylinder

 

[fuzzy]

cylinder stat

 

[stani]

cheers, but, if its a boiler change then we know that building regs state trv's, abv's and programmables but for a cylinder only is there any reg says we must do xyz?

 

[fuzzy]

dont think part l only refers to boiler swaps but to any upgrades? cud be wrong
