What in the life is this?

[Harvest Fields]

Can anyone please explain the pipework on this cylinder to me. It’s got a mate of mine scratching his head and I have never seen one before in my life. I understand the concept but the pipework and configuration make no sense to me.

 

[Gasmk1]

cant see it

 

[Gasmk1]

blending valve on the top connections to stop scolding water temps

 

[Gasmk1]

is it using the cylinder as a heat store

 

[jtsplumbing]

Looks like some strange type of het store But never seen anything like this, is this in an ex council house ? cos they did some very strange systems

Yes mate. But cannot Work out the pipe connections for the heating? Something doesn’t seem right.

Not sure. I have text him and asked him the question

He said possibly ex council

thermal store ?

 

[ShaunCorbs]

figured it out

Blending valve pipe with shock atrestor on hot out
Pipe going to bottom of cylinder cold tank into tmv and cylinder

Left pipe coming out of tmv blended hot

Defo a thermal store mate

The one going into the TMV and bottom of cylinder is mains pressure mate. (Apparently)

Yea so coil is under mains pressure normal so that means he's got high pressure at the hot tap ?

Yes mate correct

Two options either swap for another thermal store or change for an unvented and run a discharge

 

[Scott_D]

The F&E for the heating system is usually on top of the cylinder

We both said is the pipe top left just another HW draw off?

It is mate it’s a combi cylinder. It’s all the pipes we were questioning.

Edit no it can't be a hot (was thinking src) but no

could be flow from the boiler

I thought that but second guessed myself. Then it would exit where the pump is?

Correct

This in a hard water area seems lots of corrosion on some fittings, where does the silver pipe behind the pump go ? could do with a couple more photos from a different angle
