Potterton Envoy Condensing Boiler

When i moved to my new house a few years ago, this boiler was already fitted. I had no trouble for a year, and then suddently with no warming it broke down. I had someone out who told me this model is notorious for breaking down, and he advised me to take heating cover out, as chances are it would break down again. Well it did break down again, and again it was the circuits. Luckily i didnt have to pay anything, but i have to say this is a very unreliable boiler. I'd definetely advise you to have it serviced every year, as this should prolong its life and prevent too many problems. It is ok in design, plain white with a long door which has ...

It's the end for our envoy. Installed in 1997, it broke down after 6 months needing a new PCB and resistor conversion to fix a 'known' problem. For a few months all was OK until the Hot surface ignitor disintegrated into a pile in the combustion chamber. this was closely followed by the flame sensor failing and another PCB. We had the usual 'O'ring failures resulting in the combustion chamber filling with water causing some worrying rumbling noises but with a little TLC, I have to say for an early example of condensing technology, it hasn't been a complete disaster. I don't know how much longer it would have lasted; I suspect the Ally heat ...

I inherited a 4-year-old Envoy 80 when I moved house. It's now 8 years old and, touch wood, we get along nicely now.
The PCB went fairly quickly, £235 inc VAT, and the tray collected water which the engineer put down to leaky pipe fittings.
On closer inspection it was a perished O-ring seal in the combustion chamber, which I replaced.
I then bought an 80 on E-bay for spares and for the last three years it's just a case of changing seals, flame sensor and igniter, usually once a year.
I could do with some combustion chamber insulation pads though and Potterton aren't too forthcoming on this.
All-in-all, not a bad boiler as long as you're not scared of getting stuck in.
