    Trianco TRG80 - fire keeps dying

    Hello nick49 - I appreciate your input. I'm still having the same problems: if my boiler stays in for 3 days, it's a major triumph. Declinkering is now pure guesswork: sometimes it helps - loosens up the firebed (so I think) and lets air through - sometimes it makes things worse: I...

    Trianco TRG80 - fire keeps dying

    Thanks for your message. But does my fuel sound bad to you, from the way I described it? And is there anything I might have overlooked that could go wrong with my boiler?

    Trianco TRG80 - fire keeps dying

    Thanks for your post, Terrywookfit. Just to be sure that I understand, and have joined the dots correctly: are you saying that the presence of so much ash - and no hard clinkers - basically proves that the fuel is crap? I have always suspected that clinkers - melted stuff fused together, hard...

    Trianco TRG80 - fire keeps dying

    CPL now claim that another customer is using the same fuel as me - including some that was collected from me! - "with no problems". (Whether they have actually asked her or not, they don't say; it may just mean that she hasn't complained. Still.) So my question is: can there possibly be...

    Trianco TRG80 - fire keeps dying

    Thanks, wellfan, for your message and support. We're in SE Cornwall, near Liskeard. Two other (reasonably) local coal merchants seem to have stopped stocking anthracite quite recently, so I probably have few options here. I know exactly what you mean about declinkering being a bit hit and miss...

    Trianco TRG80 - fire keeps dying

    If anyone is still tapped in to this post, I still need some help. I've had four lots of anthracite grains to try - three small batches in addition to a big order in March - and I'm afraid they are all the same. The boiler struggles to keep going for more than a couple of days before the fire...

    Trianco TRG80 - fire keeps dying

    Boiler - lit yesterday afternoon - went out again today. Fan was blasting away at 7 a.m., and all heat leak rads were lukewarm at best - they had been warm/hot to the touch all day and evening yesterday. It always seems to happen in the night that the fire drops to the point where it won't...

    Trianco TRG80 - fire keeps dying

    The valve on the heat leak rad in the bathroom is seized solid - it's been untouched for 40 years, so no surprise. But are you saying that if I shut down all the rads - in the house? or just the ones that heat up by themselves (secondary heat leaks, so to speak) - that in itself might get the...

    Trianco TRG80 - fire keeps dying

    Are you saying that BOTH 1" pipes going into the cylinder should be hot to the touch (maybe one hotter than the other, but both hot)? If so, that would be a big clue. Thanks for the other suggestion - the leak rad. In fact, there are at least 4 rads that get hot from the boiler - heat creep -...

    Trianco TRG80 - fire keeps dying

    I'm no plumber, and don't know which is the "top pipe of the coil". I think we have two one-inch pipes entering the cylinder side wall - one very low down, which is pretty much cold, and one about halfway up, which is actually very hot. Would that be the one - the higher one of those two?

    Trianco TRG80 - fire keeps dying

    Thanks for replying. All our problems began with a delivery of poor-quality fuel back in March; I won't go into it all again (it's all explained at great length earlier in this thread!). So it's difficult not to see the DHW problem as a direct result of that - otherwise it would be a big...

    Trianco TRG80 - fire keeps dying

    Hello again, Have relit the boiler again after the summer shutdown, using a different batch of anthracite delivered in July. Too soon to tell if the coal is good or bad; but I already note that for some reason the DHW is still not getting properly hot in the cylinder, even though pipes and...

    Trianco TRG80 - fire keeps dying

    Thanks for your message! Sounds as if you have had similar problems, then. We're on our second Trianco since 1976 - now it's a TRG80. Never (knowingly) had a problem with the fuel until now. But it has to be the fuel. The problems started exactly when I started to use the anthracite grains...

    Trianco TRG80 - fire keeps dying

    Very hard to see - airing cupboard very tight, pipework very congested, and everything lagged in years of dust and fluff! But what I think I see is this: the 28 mm pipe that enters the side of the cylinder at the bottom seems just to run away to a 90-degree elbow and then goes down through the...

    Trianco TRG80 - fire keeps dying

    Can't take a photo at the moment, as I rely on my wife's phone for that. But I think it is the pipe that comes out of the top centre of the h/w cylinder, turns back towards the back wall of the airing cupboard to a T-connector, and then branches left and right; I think one of these branches...

    Trianco TRG80 - fire keeps dying

    Thanks for your reply. We have a ladder-style towel rail in our shower room, the top half of which is technically above the top of our h/w cylinder. That towel rail, and three other rads, always get noticeably warm/hot by "heat creep" (= gravity circulation?). But that's always been so - and...

    Trianco TRG80 - fire keeps dying

    Hello again Terrywookfit! My coal supplier has agreed to collect the remaining anthracite for a refund: turns out other customers have had similar issues after all. Some are "managing" - so I'm told - by adjusting their "settings". What settings?? As far as I know, the only adjustable...

    Trianco TRG80 - fire keeps dying

    Thanks for that! I've just discovered that on this occasion there was some kind of blockage at the bottom of the fuel hopper. Something prompted me to stick a poker down through, and fuel immediately slid down through the gap. The fire is now coming up well. This is baffling, since the...

    Trianco TRG80 - fire keeps dying

    Just for future reference: is the cable connector just a straight pull-apart job? Or is it twist and pull, like a bayonet-type lightbulb? If I get that wrong, I'm liable to break the wires. It wouldn't come apart for me with a straight pull, and I was nervous of applying any more force...
