Combi Expansion Tank

[suts89]

Been having problems with me combi loosing pressure, i think the problem is with the expansion tank/vessel.

Can anyone explain what effect 350m of 14mm UFH pipe will have on the operation of the expansion tank?

Thanks in advance.

if you don't over heat the water and keep it at an optimal 35c for the floor it will have minimal expansion....

Been a while since ive been on the site but i just wanted to update those who may be interested in my Combi problem.

Basically i fixed it

It was the expansion tank and after a couple of attempts and some instruction found on here i got her charged back up.

The pressure has now been steady for around 5/6 months.

Cheers
