Potterton Puma Combi Boiler Repair in Dulwich

Potterton Puma combi boiler repair in Dulwich, South East London: a typical example of a combi boiler that can always be repaired. The design is different which can make them seem a bit more difficult to repair than "normal" boilers.

I regularly carry out Potterton Puma combi boiler repairs in Dulwich, Nunhead and that part of South East London. For some reason there seems to be a relatively high concentration of them around there. People call me on a regular basis because they have been told by a central heating engineer that this boiler can't be repaired, and need to fork out for a new one. So far, this has been nonsense in 100% of the cases for Puma combis.

The usual excuses are brought up e.g. parts not available any more, or the boiler is dangerous.

Repairing Potterton Puma Combi Boiler problems in Dulwich

potterton puma repaired

What goes wrong with Potterton Puma boilers? In the majority of cases, it is one of the following reasons that cause the problem. The pcb is rather exposed in this boiler and has been known to fail. Especially on the models with a permanent pilot light, the fan can be worn/faulty.

Central heating systems that suffer from corrosion and limescale, have an increased chance of problems with the diverter and the pressure sensor. If the installation was not quite done to spec, you may find a lot of corrosion. Dulwich and/or Nunhead ( like most of south east London area ) also suffer from hard water and often low mains pressure which does not help. As a result, not only the boiler, but the whole central heating system is full of rust, limescale and magnetite.

This is a typical case where a new boiler will NOT solve the problem, and a boiler repair is much better than a cheap replacement. Because the whole central heating system is full of gunge, a new boiler will work for a while, but in all likelihood, the problems will come back. The only way to get rid of this kind of contamination, is by using acid. That means almost automatically the need for a powerflush.

POTTERTON PUMA COMBI BOILER REPAIRED 350w This is not cheap, but it is important to realise that the cost for this treatment can NOT be deducted from the cost of a new boiler when you weigh the costs; it should be done in either case. The good news is, that once the system is clean ( and is serviced when due ) THIS PROBLEM WILL NOT COME BACK! That also means that when the day finally comes that you do need to change the boiler, it will be less expensive because no cleaning of the central heating system will be needed.

In more than half of the Potterton Puma combi boiler repairs that I have done in Dulwich and Nunhead, corrosion/rust/limescale was either the cause of the problem, or a major contributor. All and all, the Potterton Puma combi boiler is not of a fantastic build quality, but it is not a really bad boiler.

There are still many thousands of them around. In general, people that own one and have it properly serviced every year, should expect to get on average another 5 years out of them.

How can I guarantee Potterton Puma combi boiler repairs, and keep them working for years to come, when other central heating engineers in south east London have assured you that it is beyond repair?

For one thing, I don't like replacing/installing boilers and therefore I make much more of an effort to repair the old boiler in stead of trying to install a new one. Secondly: experience and knowledge. I know the boiler, I have serviced and repaired countless numbers of them. I know the weak points, and most importantly for you, I know how to solve the problems they present. I have had them in bits, completely stripped. I know where they leak and where they block.

Potterton Puma Combi Boiler models that can easily be repaired

Potterton puma repairs

There are several different versions of the Potterton Puma combi boiler.
Puma 80 G.C. No. 47 590 10 has a maximum output of 24 kW and a permanent pilot light.
Puma 80e G.C. No. 47 590 11:maximum output of 24 kW with electronic ignition.
Puma 80 G.C. No. 47 590 01 has a maximum output of 24 kW but has no adjustable temperature control, contrary to the other two.
Puma 100 G.C. No: 47 590 12 has a maximum output of 29 Kw and a Permanent Pilot light.
Puma 100e G.C. No. 47 590 13 has a maximum output of 29 Kw and Electronic Ignition.

Some faults appear on the models with the pilot, some on the ones with electronic ignition, and other problems can happen on any model. Although I can't support it with scientific evidence, from my experience as a central heating engineer in south east London where there are a lot of Potterton Puma combi boilers,I have the impression that they are a bit more sensitive to lack of a "clean" electrical supply than others.
As with any boiler, they should always be protected by a 3 Amp fuse, not 13 Amp.
