I’d be grateful for your thoughts please...

We have an Ideal Classic NF50 Boiler with a Lifestyle Model LP522 programmer, a Drayton Digistat 1 Roomstat controlling Hot Water & Central Heating connected to a Drayton MA1 Mid Position Actuator.

We had a problem a month or so ago whereby the Central Heating intermittently wouldn’t work.

The boiler fired up when the Hot Water was turned on and the Heating also started working again after a few minutes.

I bled the radiators and put some more water into the system and it has been working OK until the same thing happened a few days ago.

This time the CH only kicked in when we ran off some hot water from the cylinder and the system activated itself.

I got an engineer in and he checked the system out (including the Actuator which I suspected) and (Murphy’s Law) everything worked OK!

The only thing I did again this time was to put a bit more pressure into the system before the engineer came!

(I have never trusted the water pressure gauge BTW)

Would insufficient pressure in the system cause these symptoms or could it be another fault?

Your advice would be much appreciated.

The system is best part of 30 years old so it doesn’t owe me anything and I’ll get it replace in the Spring when things get back to normal but it will have to do for now even if it has to limp along.

Cheers.
