Unused .purchased wrong one took back for refund .
easy to use cleaned my system well, bit of a pain having to flush the system
Very good value compared to other similar products
good cleaner not to mention it's price worth a try
I’ve used this product previously and it keeps the heating system clear.
Just fine as a general central heating cleaner. No point in paying much more for names brands - they all do the same thing and this one is just as effective.
Have used this before on my own system and had great results. Flushed out radiators on one of my relatives with same results.
My system water was really black so I thoroughly flushed out the system with drain continually going to toilet and mains water being introduced at the same rate (keep an eye on the system pressure gauge to make pressure doesn't drop/disappear), I had the pump running during this time with all rads open to ensure all dirty system water was dumped. By this process of 'dilution', the water in the entire system ended up crystal clear.
I then introduced the cleanser, left it running for three days, and upon draining the water was indeed discoloured so the chemical obviously lifted some dirt. I then refilled with Corgin Inhibitor.
It is impossible to say how thoroughly the cleaning process has been but on face value, it looks OK.
Good value and easy to apply.
I use this every year to clean my sealed system. Its low cost, and keeps the system clear.
Boiler had started to bang a while ago so tried this product which was considerably cheaper than most on the market. Drained and added cleaner to system and the boiler had immediately stopped the banging noise. Within a day or so all the radiators felt hotter and even the thermostatic valve plunger in one of the radiators had freed off and began working again.Great product.
Took 2 days to clear a blockage
Left in system two days. Perfect. Drain down refill clean water flush again. Added inhibitor.
Ran the 27 year old CH system with this cleanser in for a couple of weeks before draining off and refilling. A lot of gunge came out so it appears to be a pretty effective product at a reasonable price.
Bought it last month,well happy
