Thanks for your response.

So if i have understood you correctly, what I should have done to
relieve the pressure was drain by bleeding a radiator, not by opening
the valve at the bottom? oops. Do I still need to bleed the radiator?

The pressure is now remaining constant at 1.5 but does not seem to
fluctuate anymore, even when the central heating/hot water is in
operation.

If you have a drain anywhere its as good a way to relieve *pressure*..I
generally use a radiator tho, because the reason for pressure loss is
usaully that water has turned into gas by chemical action, and its the
gas that needs removing..I have tow rads that are classic 'gas traps'
these get bled every time I repressurise

Hi folks.
Im new to this group. I know nothing about boilers or plumming (recent
home owner) and have had a search through this group already to see if
the topic has been covered - some of the jargon has thrown me a bit!
I'd be very grateful for any advice!
Yesterday I noticed my boiler had an error code on the display telling
me to increase the water inlet (the pressure had dropped below 1.0). i
opened the tap a bit more and went on my merry way.
Do you mean you opened the filling loop valve and left it open? Could
you define "the tap" and "a bit more"? Photos are always good.Ah. You open the filling valve, until the gauge reads 1.5 or so, then
close it.

Release pressure to get it down by bleeding a radiator.

When I woke up this morning, there was water dripping out of a small
valve (some kind of pressure release valve?) at the bottom of the
boiler and I noticed the pressure guage was fluctuating betweem 3.0
and 4.0, im guessing that's not good.
Your guess is correct.
