Recommend me some wet pressure gauges

[wizbongre]

With our fancy new boiler, there is no analogue pressure gauge and the only way to check the pressure of the system is to turn the boiler to standby (i.e. DHW & CH off) which is a faff.

I've done a quick bit of Googling but can't find what I think I want - 15mm pressure gauge that can be plumbed in to the main flow/return pipework and show permanent pressure for the system without me having to meddle with the boiler. If I could have pressure AND temperature, it would be even better as I could add 2 to show flow and return which would help with overall balancing.

Any pointers where to go?

A bit more searching and I came across this https://www.bes.co.uk/combined-pres...-6-bar-bottom-entry-21922#product-details-tab which I believe would need something like this https://www.bes.co.uk/22-mm-x-22-mm-x-1-2in-compression-x-compression-x-bsp-f-tee-17679 to plumb it into existing 22mm pipework.

The only thing I'm not sure on, is if these gauges are ok with a wet pressure/temp source? Maybe that is a stupid question?!

That'll be fine, look up how a bourdon tube works. It'll respond whether the working fluid is liquid or gas. Clearly one wouldn't want it corroding and popping.

Thanks for another Google rabbit hole for me to go down...
