Boiler Identification

[jaydebruyne]

Anyone know what boiler this could be?

The casing was literally just a metal sheet covering the front and sides, no branding and just rested on the top.

Need to replace the stat on the hot water side.

Cheers

Is it a boiler? or just some sort of metering station
On a district or communal heating system

Its an electric boiler...

Pretty sure that looks like a metering station for district heating. Looking at the pipework there will be flow and return in from Heat scource. Flow and return to heating. Cold Jains. Hot and safety valve.

But it has 2 heat exchangers...??

 

[Chalked]

One for heating and one for hot water production.

+1 there will be a data plate somewhere inside or on the back of the cover

Thats what it looks like to me.
Referred to as a heat interface unit, consumer interface unit or hydraulic interface unit.
A quick search found this that looks mighty similar

Sorry I thought you meant communal.. That's why I questioned about the heat exchangers.

What's district heating?

The cover was completely blank, inside and out as I looked for one...

What's district heating?

Main set of boilers in a boiler room/ house and pipes from there to each house / flat

What's the sticker by the right prv/pi

 

[jaydebruyne]

So ... Communal then? If that's the case why would it need heat exchangers if the supply is already heated?

Heat only boilers commercial size one for hot and one for heating prob in a set of two depending on size

What sort of property is this fitted in?
There will be a central plant room with a heat scorce. This feeds a flow and return around the building/ buildings. This terminates into the heat exchangers you are enquiring about. This then produces indirect hot water and heating close to the place where needed. The meters then measure how much heat you have used.

Sorry mate, I think I'm missing something here.. This is in each apartment in a massive block of flats... Every flat has one..

 

[snowhead]

District heating is a centralised boiler /s feeding 10's 100's or 1000's of properties.

I'd agree it's a metering station

These sell the part no. you're looking at

Heat & Combustion - Gas Meters - Flow Meters - Energy Meters

So a central boiler heats the flow to all apartments which then gets reheated in the boiler pictured? That doesn't make sense.

Lol I don't see the logic in heating it twice... :/

Sorry guys, I know I must look pretty thick right now but I just don't get the logic of it...

Think of it as a combi boiler. But without a burner or gas. Instead you have a heat scource from large centrally located boilers.
This puts heat through the heat exchangers. Then when you run a tap, it get heated by one of the heat exchangers. And when you need central heating. That is pumped throgh the other.
the metering unit has no form of heating built in.

 

[jonnyswamp]

Same principle as a combi for heating hot water via a plate heat ex
Or hot water being indirectly heated in a cylinder, via a coil, by a heat only boiler

Edit
Typed the same time as Chalked, only he put it far better

Ohhhhhhhhh I get it now!!! Thanks for dumbing it down for me Chalked 😉

Not reheated, transferred.
Heat exchangers keep the water in the flats seperate from the water in the main system. there are 2 plate to plate heat exchangers because the flat is using the hot water made by the giant communal boiler to "exchange" the heat in to hot water or to the water in its own sealed radiator system.
So building main heat supply sesled and seperate from each flats systems passes through plate to plate for dhw when the flat wants hot water or passes through the ch plate to plate when the flat needs heating.

Soooo.. The stat that looks like a TRV, that controls the temp of the dhw coming out the plate to plate heat ex?

That would be my guess as the water on the whole buildibg side of the plate will be at a temp that best suits heating which will be way too hot for dhw so I would assume it is a blending valve.

Looking at it without prior knowledge It is not obvious to me which parts serve which side ch or dhw but both appear to have temperature blending much like the units fitted on some underfloor manifolds.

Where did you get this image solutions? I want to see a description for the numbers...
