Power Flushing Central Heating Systems. Top tips on how Powerflushing can be made more effective. https://www.powderflush.co.uk/
How to power flush a system better. Steven from the Power Flush Association and he's thousands and thousands of power flush jobs. And Steven is going to give us some tips on power flushing and some of the things that he does. So hopefully this video should be really, really helpful for you if you're a trainee and you're going to be getting into doing power flushing, then as I say, hopefully this will be really good. Some really good tips in this video. If you could please put a thumbs up on the video, it really helps with the videos. We put a lot of time and effort into doing these videos for you. And also if you could put a comment below, even if you just put power flush, or if you've asked some questions below and we'll try and answer them for you as well. So let's go over to Steven.

Thank you, Alan. My name is Steven and I started the Power Flush Association. The reason I started the association is because there's not a lot of information written online about the real experience and the practicalities of cleaning central heating systems, written by experienced engineers. I myself have cleaned several thousand systems and I find that there is five variables that really matter.

So no system can be cleaned 100%. It's a theoretical ideal. The closest you're going to get to that is in the high nineties. And how you do that depends, in my opinion, on these five factors. So heating the system is important, in combination with using chemicals. The filtering out of the rust and the nonmagnetic debris is also important. Flow is extremely important. And how you connect into the system makes a big difference to how close you will get to this hundred percent.

The first variable I'm going to discuss is heat. It's important to heat the system when you're power flushing it or cleaning it by any means, if at all possible. The more you heat it, the softer the rust becomes and the more it structurally breaks down. So if you had a block, the more you can heat that block, the more likely it is for that block to break down and for the rust to be kicked out, back to your machine. Now, when you're power flushing a system, it's kind of hard to have the boilers on. On sealed systems, especially. Open vented you can normally get away with it, running your machine at the same time. On sealed systems because you've dropped the pressure, they don't always want to work.

One of the tips I would say is to connect in a way where you can seal off your machine. So that you can pressurise the system, run it hot, and then open your connections back into your machine. So that you can then flush it when it's hot. And you can do that every time you want to heat it. And there's also power flush machines with heater packs built on. And there's also heater packs that you can buy and connect into your hoses. So there are many ways that you can heat the system up. There's no specific temperature. Any heat is good, but the more heat, the better. So your success rate would be higher if you used more heat for longer.

Another variable to consider is chemicals. So chemicals are important because it helps break down the rust in the system. It's important to understand that it doesn't make the rust disappear. It just breaks it down in the system. The longer you give the chemical to work, the better it'll break it down. And the higher temperature you can make it work at, will break it down better as well. A top tip is to put it in a week before, if the manufacturer allows it. Because some chemicals shouldn't be in systems that long. But it gives the chemical time to work, to be heated up, to work around the system, to soften the rust so that when you come along and do the power flush, it's already been broken down and your power flush can be done much quicker.

So there are different manufacturers for chemicals. Each one has different systems you can use it on, and different recommendations to how long it can be in the system or what it should be used for. I would recommend that you try them all and see what works best for you. Always try and put a little bit more in than the manufacturer says is the minimum. The more chemicals you have, the better results you're going to get, combined with heat and time.

Another variable to keep in mind is the flow rate. So when you have a power flush machine, irrespective of its brand, it will have a set maximum flow rate. So when you connect it onto the system, when you use it in a system, you need to try and maximise that flow rate and not hold the machine back. The best ways to do that is to focus it down to the areas you want to clean. So if you have 10 radiators, close nine of them, close the radiator and focus all your flow through just one radiator.
