Power flush vs passive filter

[Harvest Fields]

No I never said that! If you read it again and not crop it then you would see I said if you have a magnacleanse why would you buy a powerflush unit with magnets built in. Bit like buying a car then buying another engine for it.

My bad. I’m on holiday and had a fair few mate. Sorry. Misunderstanding only.

Fair enough all been there.

No comparison, power flush loads better. Better to use both tho.

Even with a working circulating pump?

 

[AWheating]

Yes. Flow rate of pf pump make the stand cir pump look like a nats fart

Also being able to reverse the flow of the water makes a huge difference.

Flow rate and reversibility.

I was the first independent in my area to have a Kamco over 20 years ago. I had started to lose work to BG on the strength of their PF'ing. I used it on all installs, but was never totally convinced that it wasn't just smoke and mirrors, compared to the "standard" chemichal flush, although the black stuff was impressive. In those days most of my jibs were BBU's out, heat only in. There were some dirty systems!

I got called to a noisy system which was a replacement BBU. The punter had declined a chem. flush.
I was honest with him, and told him that I had not yet used it to cure a specific problem. I was not going to do it free, but said that of it was not totally successful, I would just charge him half price. It was a part of my learning curve. Anyway, did the job as normal, but left it running through the HEX over lunch, so a lot longer than normal, TBF.

On my test before, it was so noisy he could not hear the TV, it was ridiculous. Afterwards, we fired it up, and had a coffee in the dining room, on the other side of the boiler wall. With the boiler up to temp, we could hear the clock in the lounge ticking. Amazing.

I got paid in full.

I sold the unit many tears later, as I had stopped doing heating, concentrating on fires. Eventually I bought the bigger Kamco on wheels, cost over a grand with all the bits, bit only used it about 4 times before becoming ill. Went to use it a couple of years later, and the motor was knackered, having been in my shed. So, yes, hiring is a good idea - but the hire shop will not have plenty pf connections. Over time of owning and using, you accumulate different fittings to get you out of trouble and make life easier.

One thing to note: they do not normally have an auto feed valve, so you have to keep a close eye on it. I started using a large seedling tray to stand it in, just in case, but stress levels were too high. I then invested in longer hoses, so the unit was outside.

Oh, and use the Kamco chemicals - FX2

Thanks for the info.

It’s the £1500 price tag that’s making me a hesitant. It just looks like a circulating pump with a trolley on the bottom. Will have to stop being tight and buy one.

Worth every penny. Use mine on every install.

The pump/motor are way, way more powerful with regard to flow rate in comparison with a circulating pump. The smallest Kamco units shift a lot of water with the smallest unit (CF40) shifting up to 90 litres per minute. These systems work by a combination of chemical action, high flow rates and multiple changes of flow direction to shift debris from the system and also to quickly discharge dirty water and refill with fresh water at the end of the process.

I think they are great pieces of kit. I think they end up paying for themselves quite quickly provided you push the service to your customers and get the jobs in. I used to enjoy spending the day powerflushing, very satisfying!
