Did you know you could improve circulation by raising the pressure in the system :eek:

Safety, production cost, practicality, user incompetence, disperate origins of parts....the list is endless.
I note that you curiously omitted "installer incompetence" :LOL: :LOL: - or is that within the "endless list" ;)

The original question was...."So why do so many recommend that a closed system be pressurised up to 1 to 1.5 bar cold?" :)

To my knowledge 1 bar is one atmosphere, which is the weight of the air at sea level. If the sealed pipes are 1 bar then the pressure inside is the same as at sea level?

If the pressure gauge is downstairs and set to 1 bar with the house having three floors which is maybe approximately 30 foot in height (which is 1 bar in pressure) to the highest system point will the pressure at the top be less than at the bottom in a sealed system? By 1 bar? Gravity comes into play even in a sealed piped system. Gravity is always there. If it is 1 bar at ground level then it stands that it must be 0 bar 30 foot above it. Is that so?

In a normal 2 floor house, and most 3 floor house I would assume, 1 bar will get you up to the highest level with no problems. I suspect this is why they stipulate the system being set to 1 bar cold.

I am open to correction as I am going by what I learnt in school and applying to this question. :)

Yes but we are talking about pressureabove atmospheric.
But it's all relative ;) 1 bar above local atmospheric would presumably be 2 bar if local atmospheric was 0 bar and you then decided to move the whole thing 30' down to the beach.

Maybe that's what it's all about - aeroplanes and spacecraft. So installing a pressurised heating system on a plane would involve significant pressure changes depending where in relation to sea level it currently is.

So you see, it is rocket science after all :LOL: :LOL:
