Auto bypass could be elsewhere in the system. That gate valve on the coil primaries is to stop the coil resonating. There could be no check valve on the secondary return pump cant tell from the pics but is that a bronze pump?
Yikes!
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
I'm not sure what you mean by a 'bronze' pump, is that a type, colour, make?

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.

So there will be discoloured rusty water to come!
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. BoomYikes!
What would cause that, someone switching the stopcock off, as in there should be no need/ability for that to be there?
