Potterton Suprima repairs in south west London

Potterton Suprima repairs in south west London are easier for me, than for most heating engineers. This partially because I have repaired more of them over the years than I can remember. Experience helps, but if you start off wrong you will never get it really right. When I realised that most plumbers didn't like repairing this boiler, I read up on them. There are actually 3 different series; one condensing range, and 2 standard efficiency. When I combined my existing skills with this specific knowledge, I could confidently say that I can add Potterton Suprima repairs in south west London the range of 99% chance of success before even seeing them.

How to avoid the most common cons and rip offs

These boilers can be found as open vent or sealed systems, which makes little difference from a fault finding point of view, apart from lack of flow caused by airlocks. If only some of the radiators get hot, the hot water works but the heating does not or vice versa, it could well be that the problem is just air in the system. This happens much more with open vent systems and is very rare on a sealed or pressurised set up. Always worth checking that the header tank has water in it. It should not be full, but about one third when cold, to two thirds when warm. All versions have external controls, an external pump, and the vast majority have an external diverter valve (also known as midposition valve) or two or more zone valves. The timer or programmer drives the valves, and these in turn fire up the boiler. The boiler then activates the pump. When you find yourself without heating or hot water, it speeds things up if you have checked these things already for yourself. If the pump runs, but nothing gets warm, the fault is most likely inside the boiler. This is provided, of course, that it is all wired up correctly. Unfortunately this is often not the case, but nevertheless it is worth checking. If the pump is not running, you can go through a number of basic checks to make sure the boiler is actually broken. There may be maintenance works to the gas or electricity to your home causing a temporary interruption in the supply, or various other reasons whey the boiler doesn't work without actually being broken.

Potterton Suprima HE repairs

repaired Potterton Suprima The HE (High Efficiency) or condensing models are an updated version of the popular standard efficiency models to comply with the energy conservation rules introduced in 2005. Although very similar to the standard efficiency models, they have several differences. The most important ones are the secondary heat exchanger and the condensate outlet. Especially the condensate outlet can cause funny problems. If it is partially blocked, it can be the source of intermittent failure. That is the technical term for: sometimes it works and sometimes (usually late at night, very early in the morning or the weekend)the blasted thing does not. This is typically something NOT to experiment with, as a faulty condensate pipe can cause toxic fumes to escape into your home. Here is a page about them on my blog.

The difference between the Potterton Suprima L and the earlier model

The Potterton Suprima was in production from 1988 until 2009. Until 2001 it was the "regular", and after that, it became the Suprima L.
Without checking the details, most people would probably say it is the same boiler. They look the same, they are the same size, they sound the same, and when you bump your head on them, they even feel the same. Nevertheless, there are important differences, but you can only tell if you really know about boilers, and check the inside or compare the service and installation manuals that have all the technical details in them.
The first models had a small range over which the heat output could be adjusted. The Potteron Suprima L had one, fixed output. This sacrifices flexibility in favour of a slightly higher efficiency and a more controlled combustion process. The upgraded version also has improved safety features that offer more protection of the boiler in case of fault conditions. These are just two of the reasons why the internals of the boiler vary slightly. These differences may be so small that you wouldn't notice unless you know exactly what to look for, but they are significant enough to stop the boiler from working if you replace a part with one that is meant for another model.

Potterton Suprima repairs in south west London don't have to be a problem.
I have done enough of them to know what to look for, and which hurdles to avoid that are specific to this model. I also know where to get any and all spares I need for them locally. I also tend to have my electrical tester with me for those cases where the fault is in the external controls, in stead of with your the Potterton Suprima itself.
Depending on the time of day, what exactly I need and where the patient is, I can often get them the same day. Where that isn't possible, it is virtually always the next day that I can lay my hands on what we need. That means that you have a good chance that I can finish the job within 24 hours if you live in south west London and need a Potterton Suprima L boiler repaired.
