Pressure dropping

[howy1]

Hi all, I did try and post this earlier so forgive if it comes up twice, I have an unvented central heating system that I have to keep topping up , I don't have any show of a leak so I just wondered where else it might be going . Cheers howy

do you have to bleed the system much?

 

[howy1]

Hi Shaun , I don't have to bleed system as I only allow it to get to 1 bar so rads are always hot when on , cheers howy.

no i mean do you have to bleed the system of air regular ?

 

[howy1]

No , as said rads are always hot even upstairs , just pressure dropping , cheers

any pipework in the floor ?

does the pressure relief valve drip ?

What does the pressure gauge read when it's running hot and what is it on when it's cold?

 

[howy1]

Can't feel any water from pressure relief valve , all pipe work is concealed as its a year old new build , Simon if I am honest I have not watched gauge from cold start to hot but I have been pumping up to approx 1.3 bar and after couple days it's down to 1.0 bar , what would I look for in respect of running pressures or is there something I should watch for cheers howy .

Does it drop below 1 bar?

Hi Shaun , I would have to leave it to see if it dropped below 1.0 bar howy
