Hi all,

I can't for the life of me find my manual for this boiler,

does anyone know what the precharge pressure in the expansion vessel should be on this?

TIA

Jon

Hello,

Check the FAQ page, you will need a pecil type pressur gauge and a bicycle foot pump.

Thanks for the response but i am an engineer and know what to do am just looking for what the specific precharge pressure is for this model as i'm b*ggered if i can find it!

Ha ha! sorry! They are normally 0.5 - 0.75 bar, but you'd better check with the manufacturer>

I thought that they should be 0.7 but i can'y find anything to prove it as my manual has gone AWOL!!

 

[Aquaheat]
