Sealed system kit

[HawkWhiteFinger]

I don't have one handy, but was wondering, as I can't find anything on t' net, if someone has a good photo or instructions they can post as I'm interested in seeing how one is piped up, where everything goes. Thanks.

Boiler suitable for converting.
Filling loop, PRV, Expansion Vessel, Overheat Cutout and caps for feed and vent pipes.
No drawing needed IMO

Agree with Mountainman, each installation different.

Size of system will determine size of expansion vessel.

Some customers do not want pressure gauge and filling loop in loft as inconvenient if top up required.

If not already fitted consider air bleed vent(s) at high point.

 

[HawkWhiteFinger]

Ta chaps.

Excuse my ignorance.

Filling loop connected between water main and any CH pipe.
Pressure gauge connected anywhere to CH pipe.
Expansion vessel connected anywhere to CH pipe.
PRV connected anywhere to CH pipe.


Is that correcto?

 

[HawkWhiteFinger]

I guess not.

 

[JAP&H]

Sorry HawkWhiteFinger.

Ones I've fitted come in kit.

The PRV is art of a valve set that combines;

15mm male spigot for receiving compression fitting of filling loop, as you said, check valve end fitted to cold supply.

3/4" female for attaching to expansion vessel.

1/4" female for gauge, or plug if gauge going elsewhere.

22mm compression fitting for system pipe work.

15mm compression fitting for PRV discharge pipe work.

Cant see and real problems with fitting separate bits of kit around system.

Hope this helps.

Yes you've been some help, thanks.

Are the locations I've suggested fitting the components to in the right place?

 

[JAP&H]

You've got the right bit of kit on the right part of the system.

Can't see why this wouldn't work, just not tried it myself.

Expansion vessel tee'd onto the return side of the heating system normally also.
