Have owned an Envoy 40 since they first came out around 15 years ago - it has been as good as any other boilers I have heard about, During that time there has been some replacements the biggest being the Control Unit and the ignitors seem to last about four years also usually replace the flame sensor at the same time, had one temperature sensor and the rubber gaskets replaced each time and during servicing which I do - just a hoover out of the debris so I would consider this to be a pretty successful boiler. All was covered by insurance so I am very happy with it and hopefully it will continue to perform as it has in the past. The gas 'people' say I should replace it but as its a condensing boiler and seems pretty economical I just do not see the point of changing it for changes sake. So all in all one happy customer with this Potterton product so far. Would I buy another similar one - not sure as haven't looked into it but I hear that the Worcesters are a good product anyway I will look into that when the time comes unless it outlasts me !

Our potterton is the ENVOY 60, same as 80. It is now 13 years old. In that time possibly 15 breakdowns. Replacement control cards, new fire box, leaks. Most repair men struggle to deal with it. The most unreliable bit of equipment we have owned. Broke down Frozen Saturday, fixed Frozen Wednesday throwing FAULT every hour since requiring reset. Scrappage YES, and Soon.

Our Potterton Envoy 80 seems as troublesome aas everyone elses and there are numerous forum discussions covering similar problems. Most of these like our problem, are not water leakage, but failure to hold its light once ignited from pilot. This usually results in error message F which suggests loss of gas pressure. Other people have replaced igniters and sensors.

So a pretty poor product. Shame as you want ot buy british

To say that this boiler has been problematical would be a considerable understatement. It has been unreliable from new and just about everything bar the case has been replaced at least once over the 12 years I've had it. I fitted it because it was recommended by British Gas and because of Potterton's good name. Bad mistake. I've had to take out BG's Homecare service since it came off warranty and made a 'profit' on it every single year. The BG engineers are a great bunch (I'm on first name terms with them) but they blench every time they see an Envoy. Most have been scrapped now, but the lesson is clear - never buy a Potterton! The engineers reckon Bosch Worcester or Vaillant are the most reliable these days.
