vented water heater question..

[xr4x4]

Hello,

Been on a job with a non working, not wired up vented water heater.

Unit was fitted but leaked water so was never powered up.

Fixed the leak but the unit is plumbed into a (what looks like) standard mixer tap.

Now I know you have to vent them, ethier with the STD spout or with a vented tap (expensive)

Now the question, can I plumb in a 3 bar pressure relief valve (or similar )into the hot output pipe to act as the pressure relief and keep the tap plumbed in as is?

Thanks.

Paul.

Why do you say a vented tap is expensive? Just take the guts out of the existing one so it won't shut off...

What make/model is the heater? I would have thought putting a 3-bar PRV on it is asking for trouble

Would just save hassle as it's plumbed in. Also the main tap is a standard stopcock and doesn't look obvious how to work it.

It's a redring ws7.

Connect as required by the manufacturer's installation instructions, probably available on their web-site.

End of.

Did I understand this correctly?

You're asking if you can connect a vented water heater as unvented?

Are you taking hallucinogenic drugs?

the unit it's compatible from 0.7 to 10 bar.

when being heated, if/when the pressure rises above 3 bar, the valve will pass releasing the pressure.

It should work in theory, why wouldn't it work?

As said the ws7 should be fitted with a open outlet mixer tap.

It should work, but there are too many things that could go wrong with it and it doesn't have the numerous safety devices found in an unvented water heater.

Do you have PLI and does it cover you for illegal and untested amendments to heated pressure vessels? I'd guess not.
