expansion vessel: which way up?

[womble]

Hi,

I'm having a new Keston boiler and Megaflo fitted and I'm surprised to see that the expansion vessel looks like it's upside down: the threaded pipe is on the top and the car-type valve at the bottow. Shouldn't the car-type valve be on top? Does it matter?

Regards

It does not seem to matter much but I always prefer to have the air at the top.

Makes no difference. The air (or nitrogen) and water are separated by a synthetic rubber diaphragm so the water cannot reach the schrader valve.

But it does matter and yes it is upside down.

Can you explain why it matters?

Zilmet and others manufacturers prefer the air valve on top (from their documentation). Plumb it in and just make sure the scraiders accesible.

Dont worry. At least he has an immersion backup on the Megaflo

he better put the switch for it in a nice easy to reach position.
