Presure gauge up when hot water turned on

[Rutherford.alan@yaho]

Hi all.
Ok.ecolite 30 combi Erp.
Presure rise on guage into red.
Dropped the presure out drain valve on boiler.
It stabalised. But when hot water on it rose a tadge going into the red.
Bag in vessel ok. Pushed shredder valve air out no watter.
Fill loop changed.
Could the diverter be naked letting hot water into the heating side ????
Thanks

I've been about who this

No pressurised the vessel.

No pressurised the vessel.

Did you do it properly? Have you checked if the filling loop is passing? Have you isolated the cold inlet to ascertain if the plate is pinholed?

Why would we see the presure guage rising for a moment when hot water is demanding.
Must be the diverter valve acting up and hot going into heating ,or have I wasted all my time in the gas industry,the reason I came on here was to learn more,we all can learn .

I know we can all learn more it’s why I joined. It won’t be the diverter valve. If you’ve pressurised the vessel and done it properly then it could be a blocked communication pipe. How long have you been in the industry? Nothing about your posts suggested this.

Wow, 15years ,are you saying that the diverter valve can't leak from the hot demand and as a result would not sent heat to a radiator when I am in the shower for 20 min ?
How long you been in the industry.

20 years. I didn’t say it couldn’t, if you read my reply

 

[Rutherford.alan@yaho]

Normally 1 bar on expansion vessels depending on size, MFI for some boilers are half that

 

[Rutherford.alan@yaho]

No you said it WONT be the deverter valve .ets be professional it's not a slaging site and insulting flow engineers
