Part query, can anyone tell me what this is?

[divadl78]

Hello,

I work as a Legionella Assessor and recently came across this copper part which is inline with the flow on a vented indirect cylinder. The bottom is connected to the central heating flow upstream of a pump. Could someone tell me what it is and how it works. My concern is there is potential for inhibitor to contaminate the hot water supply of a clients premises.



A big thank you for any help with this.

It looks like a Hydro-Spartan unit which converts standard and horizontal hot water cylinders to work like a Primatic cylinder.

Yep - a spartan unit.

Also used instead of a F/E tank[emoji4]

Thanks fellas, i've found via google an explanation for how it works.
Basically the Spartan is in 2 sections, split top and bottom. Water from
the domestic side of the system is piped through one of the side
fittings, into the top chamber. In the middle of the top chamber is an
upstand pipe. Once the water level reaches the top of the upstand pipe
it overflows into the bottom chamber. The bottom chamber is connected to
the central heating system, this water from the DHW system is used to
fill the central heating system.
