What always grips my **** about these stories is when you look at the install it looks like they have genuinely tried to put it in properly. They've used the benders for sets and bends albeit not very well but it looks like it was installed by someone that didn't have a clue what they were doing rather than a firm that slung it in with a tail light guarantee.
Of course whatever the cause is it's the client that gets screwed but it's a sad reflection on the state of the industry
You need a site visit from someone that's properly qualified but in the meantime more pictures showing the valves and control gear along with the new boiler install - particularly the flue might help give you more ammo

MJGas - I'm not sure what you mean by a 'bronze' pump, is that a type, colour, make?
Thanks

Thanks

Yikes!
What would cause that, someone switching the stopcock off, as in there should be no need/ability for that to be there?

Will take some additional pictures tmrw evening
I think it's genuinely a case of them 'not having a clue' as they haven't yet been paid a penny!

It's the metal it is made from. Pumps for drinking water (which includes hot water for taps) are restricted to certain materials and the pumps used for central heating circulation are not allowed.
Looks like it could be this one https://www.plumbarena.co.uk/produc...AA1kP9Z-6vkta_aepu-8dRoClx7w_wcB#.VbwMv25Viko
If so, it would have a cast iron construction.

The videos of the cylinder exploding are a bit over the top in your case, ok the stopcock is in the wrong place but its not going to cause an explosion, as said can you post pics of the motorised valves ect ?
If the stopcock was shut it would isolate the unvented cylinder from the expansion vessel and the pressure relief valve.
At best, simply heating the water inside, in this scenario, would cause the temperature and pressure relief valve to open and discharge.
It's a lousy job, doesn't conform to manufacturer instructions or building regs. Not expecting much from the rest of the job on this basis.
The benchmark forms will be found in the rear of the boiler installation manual, and somewhere in the unvented cylinder manual. Would be interesting to see if they were filled out.

Oh dear, looking at the (v poor) DAB pump website it would appear that they have fitted a central heating pump to your secondary circuit. The Evosta unit data sheet does not mention a bronze version.
So there will be discoloured rusty water to come!
DAB is another one of those choices that fall directly into the 'whatever's cheapest?' form of procurement.

Well a complaint of discoloured hot water was one of the things mentioned in the first post....
(Not necessarily related though.)

Easiest way to test if the pump was causing it would be to turn off the pump and turn ff the isolation valves to the pump.
Whilst highly unlikely that something in the videos could happen. It is possible, Have you never seen a tprv stuck shut

The stopcock may well have a loose jumper type washer in it, which will shut automatically to prevent backflow and, in your case, prevent overpressurised water reaching your safety valve. Boom
The boiler can only get to 80c, the immersion isin't wired up, you would have to wait for the cylinder to be be completly cold and then shut the stopcock, turn the boiler on and when the water gets to 80c (if the cylinder stat failed) the tprv would open, if the tprv was jammed it still would not go boom.
