Simple Glow Worm Flexicom 30CX question

[doolols]

We had this system installed 2 years ago. It works fine, but we do get some loss of pressure during the winter when the CH is on.

I'm having to repressurise the system every week or two - I run it at 1bar, and over that period, the pressure will drop to 0.8 bar. Is this OK, and to be expected? Or do I have a small leak? And is the pressure OK? We run the heating from 7.30am-9.00am, and 3.00pm - 11.00pm.

We have a small chalet bungalow, 6 heating rads and 2 towel rads, upstairs bedroom / en suite.

Thanks in advance.

Gerald

Check the prv pipe out side, to see if it drips water when central is running

Check the pressure relief pipe outside the boiler.
Otherwise you have a leak.
