quick lamens question

[efiste2]

The GAS BOARD have fitted a new boiler to the in laws system, but as well as the new boiler they have fitted a (sorry for the description) a big round red ball tank type of thing next to it, The system never had one before, Can anyone hava a guess at what it is, sorry no pictures and please excuse my nieveity

 

[snb]

a pressure vessel!!

This is an expansion vessel, presumably it is now a sealed pressurised system, but why they didn't fit a system boiler is strange, unless they had an un-vented cylinder fitted as well and it is the EV for this.

If its red its on the heating

Good point

Good info chaps, cheers.............so they have converted it to a pressuriesd system and hence fitted this, what exactly is the purpose of this expansion vessel, as my system was converted to a sealed pressurised system and i havnt had one fitted..............

I have just read the STICKY section and found it on there, I guess my boiler (worcester 24i greenstar) must have an internal one.........but my inlaws have the same boiler, so how come they have had an external one fitted

 

[twgas]

could be internal vessel not big enough for system so they added an extra one, perfectly ok doing it this way

thanks for all the advice chaps
