Hot water cylinder

[NewhouseOldhouse]

The metal one is empty and seems to have been for some time.

All pipe work now runs in and out of the black plastic tank and I have looked no smaller tank only the black tack!!

Hmmm. Picture of your hot water cylinder and pipework would be handy, it may have an integrated primary header tank.

 

[NewhouseOldhouse]

Not sure if these are any use but pipes are above the cylinder

 

[oldbutnotdead]

Bit hard to tell what's going on there. But there do appear to be enough tubes going upwards for 2 header tanks as well as some oddities (like the copper bulge which looks too small to be a low loss header and the reducing T).
If you've only been in the place for 4 months (ie this is your first winter) you might want to get someone in to have a look, you may have inherited some massive bodge from previous owners. Local solid fuel installer would prob be best

Indeed, the copper bulge is a strange one , maybe a device to allow one feed from the CWSC ? I have seen similar, but a different shape. The 28 dropping down then reducing ,at that height makes me wonder if it's a looped gravity circuit and that's the flow connection to a annulus heat exchanger - not a coil Before you contact an outsider, you could empty the cupboard and remove the lagging jacket, then " the dog'll see the rabbit" In any event I would not renew the cylinder, it's probably a lot thicker metal than a new one

It could be an air separator.

Where is the copper bulge u say??

Also, do u think there would be a thermostat on the cylinder?

Could be, hard to tell from that pic & odd place to have one.

Right hand side of pic 3

Possibly no thermostat on the cylinder (except the one in the immersion heater but ignore that for now). Quite likely your system is gravity hot water and pumped heating, in those circs a cylinder stat would be a nuisance

 

[NewhouseOldhouse]

Any use

Thats the thermostat with control at bottom

 

[oldbutnotdead]

OK. The copper bulge (pic 3 of the latest batch) is the immersion heater.

I'm wondering whether that reducing T (pic 6 of new batch) is an injector T fitted by a madman.

And I don't like the way the cylinder output is near horizontal- made that mistake myself once, you can get an airlock in the cylinder & into serious pressure problems, especially with the woodburner in circuit.
Is that a bleed valve at the bottom of pic 5 or just a lockshield
Do either of those pipes in pic 5 get hot when the fire/oil boiler is lit

 

[NewhouseOldhouse]

Not sure what it is at bottom of pic 5 it could be.

Yes the T connection the larger end gets hot when fire/oil is lit

 

[NewhouseOldhouse]

When I took jacket off top of cylinder is hot only

 

[NewhouseOldhouse]

It's a locksheild by the way
