What Is Power Flushing?

First, we must understand what it is that we’re doing when we perform a power flush procedure. An unavoidable reality of the way central heating systems are manufactured is the build-up of rust over time. This rust accumulates in your radiator and boiler, where it poses a risk to the water flow in your central heating system. There’s no practical way to avoid this kind of build-up, however, a power flush will stop the build-up from becoming significant enough that it causes problems with your central heating. By flushing a specialised mix of water and chemicals through your central heating system, your No1PHD technician will be able to clear out that build-up, leaving the water in your system as free-flowing as the day your radiators were installed.

How do I Know When I Need a Power Flush?

One of the first things to consider is; has your Southampton property’s central heating system ever had a power flush procedure performed on it? If the answer is no, and the system was not recently installed, it’s probably a good idea to have a power flush as matter of basic maintenance. Alternatively, if you notice your boiler cutting out or making banging noises is usually a pretty good sign that something is going wrong internally. The likely culprit is the pump being jammed by the debris clogging up the works. In these cases, the water is not being circulated and so the water in the boiler heats up very quickly and the boiler will shut down as a matter of safety. If you’re experiencing other problems and would like to know if a power flush could fix them, talk to one of our Southampton central heating experts for advice.

Wait, Rust in my Radiators?

Your radiators are filled with water and they are made of metal. Usually steel. Water and steel combine to form rust, which is how it gets into your central heating system. It’s the radiator itself rusting from the inside. If you’re wondering why they are designed this way, the simple answer is “cost”. Radiators could be made from something non-ferrous that doesn’t rust, or perhaps filled with a different heat exchange medium that wouldn’t react with the iron content of your radiators, but the cost-to-benefit ratio doesn’t add up. It takes so long for a radiator to rust to the point that its structural integrity is compromised that it doesn’t make economic sense to make it out of more expensive materials. Radiators will more often than not be replaced or removed long before they ever rust through.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
