Discuss New Glowworm Sealed System Boiler with NO Pressure Gauge in the Central Heating Forum area at PlumbersForums.net

We had a Gloworm Energy 7 30r Boiler fitted in Jan 22 to replace a British Gas Boiler (which was a Glowworm Rebranded ) when the heat exchanger split after 10 years. The old boiler had a pressure gauge on the fascia but this new model is not fitted with one. After it was all fitted I queried this with the Engineer (Glow worm Approved) and he said If I wanted one he would have to drain down the whole system, fit a guage somewhere and then refill, bleed etc + all inhibitors etc at my cost. As we were stretched at the time - as we had not expected the old boiler to fail after only 10 years - I told him to forget it and we would discuss it when the boiler was serviced.
My question is can a Pressure Bar Gauge be fitted to the existing live pipework via one of those washing machine type adaptors with on/off valves which screw into the pipework forming a hole without draining down the system. The valve and the adaptor are as cheap as chips!!!
Secondly, as the instructions state that the owner should check and top up the system monthly to maintain the correct preesue which is unattainable without a pressure guage on the system. Was the installer at fault by not installing one with the new boiler.??
This problem has come about because I bled all of our radiators before I fired up our boiler for CH (4th Nov) and the two top rads (in our loft) would not bleed, so I put some pressure into the sytem to get the air out. Now the boiler will not work and a call to the Technical department thinks that it is not modulating. It is however working for producing hot water to the cylinder. I have a full parts/labour 10 year warrantee.
The warrantee guys are coming monday but after lots of research today I am concerned that I may have inadvetenly caused the problem and I might have to pay to correct the problem.
All advice gratefully received. Brian
 
It’s a digital pressure guage pg8 of the user manual

You have a red expansion tank correct isn’t one on there ?
 
I’m guessing it has a red top valve on it (don’t touch it ) ?

No...It has a small black ''tyre valve cap'' sized bit on top. It is a Zilmet 4 bar 130 cal pro.
Have also pressed the +&- buttons 5 secs but no pressure is shown, Also deactivated the heating rad sign and tried again ..no pressure shown but S 30 came up. Thought it was 530?? Tried pressing again but nothing comes up only the 2 horizontal bars

Would recommend fitting that eg swap the heating valve for that

If your ok with compression fitting turn both valves off remove the flexi off the cold water / mains side eg leave the heating side attached

Open the heating valve while the flexi end is in a bucket (slowly open the valve )

Once stopped / down to a dribble close the valve get the new guage valve handy undo the compression nut on the heating old valve and swap them over and tighten the nut back up and refill etc you will have to go round bleeding the rads etc

Thanks Shaun, Great Advice. Will buy one tomorrow ready for Warrantee engineer on Monday and he can fit it whilst carrying out the repair. Really appreciate your time especially on a saturday night when you could be watching Strictly. If you were close would happily buy you a pint (Happy hour only!!!) Thanks Brian
 
They won’t fit it if it’s the warranty engineer from gloworm
