I'm after some advice,
I have a Glow worm hideaway 70 boiler which is designed to run a vented Central heating system. I need to remove the header tank that is in the loft and as such want to convert this to a sealed system. The problem is that in the documentation for the boiler it states that it shouldn't be connected up to a sealed system. However in the same document it also states that the header tank can be anywhere from 1-27 metres above the centre line of the boiler. If my maths is correct 27 metres give you a pressure of 2.65 bar. If I used a sealed system but ensure that the pressure never gets above 2.65 bar using a pressure relief valve do you see any problems with converting this system.
It will only be short term as the boiler will be replaced in the next 6-12 months.
Thanks in advance
