Fail safe hot water... Can u foresee any issues with this

[Mbear]

Imagine a combi supplying hw to kitchen only, an unvented cyl supplying bathroom suite and power shower. One kitchen one bathroom, nothing fancy. Now can anyone foresee an issue with this......

The hw pipe supplying the shower has a stopcock fitted inbetween the cyl and the shower, then the combi hw supply going to the shower aswell, again it has a stopcock on it before it finally gets to shower supply pipe. You would use the cyl primarily for the shower hot water (combi stopcock closed&cyl stopcock open), then if the cyl ran cold for any reason for eg faulty zone valve/stat or just back from holidays etc u could turn cyl stopcock off and turn combi stopcock on to instantly supply the shower with hw. Its just an idea I had for my bathroom when I do it up, I want a proper power shower by plumbing in an unvented cyl to the combi but I want the security of instant hw from the combi.

I can't really foresee any issues myself aslong as only one stopcock is opened At any one time. What do u lot think?

Could a 2port hold mains pressure at bay without passing do u think?

For eg gate valves aren't great at holding mains pressur

you're right mbear think solenoid valves would be a better idea bit pi**ed last night lol
