Ideal Pressure in a mains pressurized central heating system when off (cold)

[jonnystewart]

Hi,

I am topping you my mains pressurized central heating. When it is turned off (cold) is having 1.5 bar pressure in the system too much?

Any information is greatly appreciated.

Thanks

Jonny

what do the manufacturers instructions specify?
are you having to top up repeatedly?
1-1.5 bar will usually be about right
