      not worth it.

      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 dials, etc behind it. Though it is quite long, and sticks out in a small kitchen.

      It isnt the best on efficieny, and my gas bills are pretty high every month. It gives a good heat though, and my shower is always quite strong and hot.

      These arent the cheapest of boilers, and i really wouldnt recommend getting one. The pilot light notoriously blows out, and the reset buttons is prone to sticking.

      The customer care is not the best with potterton, and i found there team useless when i first called up with a query about the potterton boilers. Personally i wouldnt bother, spend your money are a much more reliable boiler.

      A love hate relationship

      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 exchanger is pretty near paper thin after 11 years service, but it's still serviceable. The reason we're replacing it is we are installing a conservatory and need to flue through a pitched roof rather than the wall. Not worth trying to get the bits for an 11 year old boiler!

      The spares in the cupboard (essential as it would always go wrong on Boxing Day or Good Friday) soon to be on Ebay!

      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.

      I have had my Potterton Envoy for about 18 months, since being fitted by, and now maintained by British Gas. Until very recently, it has performed flawlessly, delivering the 30% saving in gas as promised. However, just before Christmas, it refused to light. A change of igniter solved the problem for about a week - the cause of the igniter failing wasn't discovered until it failed again the week after - the combustion chamber was full of water. This was put down to heavy rain beating on the side of the house whilst we were away in Canada, drained off, dried out and re-ignited. This lasted a day or so, before failing again. On closer inspection, the main heat exchange was leaking, having a split/hole in the aluminium casting - there's nothing like a couple of pints of water to make something difficult to light! They tell you to expect more steam, but not this much! The heat exchange, which forms the guts of any boiler, and more so in a condensing model was changed for a new one. We still have one minor fault, a drip of condensate probably caused by the sealing gaskets all being shagged out, having been on and off the thing so many times! I await the repair with interest. One good piece of news amongst all this - because of my 3 Star Contract with BG, I am only paying £11/month to get what in effect is my boiler rebuilt! Not bad value when you see the price of a heat exchanger. This hasn't put me off the principle of condensing boilers, just this one! It also encourages me to persevere with maintenance contracts, especially if something is newer technology.

        Potterton Envoy Condensing Boiler. From everybody's point of view, this is a boiler to be feared! Potterton have made some great boilers, and still do, although they do put their name on some inferior boilers due to to a recent merger with another maker (I'll save their blushes).It's fine when it's going, apart from the slight unusual whining noise from the combustion fan, and it's size allows it to be hidden by a kitchen cupboard. When I worked for British Gas, we had two of them on a three star contract. I new both the owners quite well, I was there so often! One guy gave me bottles of lager every time I went there! The other split it's heat exchanger, flooded the kitchen and had to be replaced. They are unlike most other boilers if only with their unique 'hot surface' ignition system. I have changed these countless times. Another common fault was the condensate leaking from the combustion tray because the seals split, or the fragile metal clips holding the thing together corroded away. As it is room sealed, that it quite a serious fault! If you have one, I seriously urge you to go on a service contract with somebody, Potterton perhaps, it will save you money in the long term. I prey that it does not go wrong.
