Basics first, check the pressure on your system. Should be just over 1 bar cold.

Ive got the feeling that this may not be a sealed system!

YES IT IS DEF a sealed system, it has a expansion vessel to rear of unit and prv just above pipe connectors on chasis if you look up from the bottom of it,
but i will def check cold pressure in morning as im sure just after it fired up the other day it was low just in red on dail but came up to about 1.5 bar when hot. Thanks for advice i will keep you posted!
