Horizontal expansion vessel

[davphi338]

Hi

Just had a new boiler installed with a supplementary expansion vessel. The installer has fitted the expansion vessel horizontally rather than vertically. I don't think this is good practice. I presume the flexible hose wasn't long enough, I've contacted Zilmet to see if the warranty is voided with horizontal installation. Is it worth getting installer back to fit vertically or is the install OK. I also noticed that it transitions to plastic pipe within 1m of boiler which doesn't comply with Ideal vogue installation instructions. The system plastic pipe was like this prior to the new boiler but was hoping the installer would have rectified during the install of the new boiler. Any advice much appreciated.

Did I look up expansion vessel fitting instructions to see if it can be installed horizontal?

I have seen the expansion tanks like that before. It has not been an issue. I am not a plumber. I am a decorator.

If the system is maintaining mains pressure, I don't see what the problem is,

The expansion "tank"is there to deal with potential drops in pressure.

Again, I am not a plumber

I contacted Zilmet the manufacturer of the vessel and they stated the warranty would be void if related issues arise as the vessel should be mounted vertically.

I'd be curious to know why.
I don't see how the orientation of the vessel will affect its performance, given that part of it contains water, and part of it contains air.
