Potterton Promax HE plus

[Keith1978]

Hi, just after a bit of advice please. I have the above boiler and it keeps failing to fire until I press the reset button.

About 2 years ago I had TRV's put on all rads apart from the room with the stat installed, whereas before there were 8 rads without. Since then I've had this issue.

I have British Gas homecare and have had them out to look a couple of times, first time the guy said it was because the stat in the boiler was up too high (it was turned right up) so he turned it down as he said it was overheating.

Second time the guy changed loads of parts, but it's still happening intermittently.

Could it be because of the TRV's being fitted that the boiler is overheating, I'm thinking if all the TRV's are satisfied there's not enough in the non satisfied rads to take the heat away from the boiler. If thats the case would turning the internal
stat down some more solve the issue? Anyone with any experience win this boiler know where it should be set to?

Obviously I'm aware that I can get BG out again but just looking for a second opinion really.

Take the TRV heads off and then see what happens. It's a Promax. Probably one of the worst for any fault you can imagine in recent years. Get BG back.

Thanks I'll give it a try. I will get BG back in but seriously considering if it's worth looking at a new boiler in the near future rather than the hassle of this one going forward, it's 12 years old this year.

Do you own a car? How old is it?

I struggle to see the relevance but I'll play along, no I lease a van and it's 11 months old.

The relevance is to do with how much you'd put up with something, that you heavily depend on, when it starts to frequently cause you problems by developing faults, cost you time and money, is of a certain age and was, perhaps, not the best product in the first place.

Hence why I'm considering a replacment, unfortunately I never chose it, it came with the house.

My original query was more to do with whether me having extra TRV's installed could have caused or contributed to these problems and whether the flow temperature setting could make any difference.

12 years for any Potterton is good going

It is a pretty unreliable boiler.

But what heat output is it?

What total power are all your rads? [ You can compare their sizes with similar ones in a catalogue like Screwfix.]

Do BG think you need a powerflush ?
