"Adding this to the water is done by one of the radiators and takes about 10 minutes in all. No mess, no need to follow instructions the kit comes with a number of fittings to ensure it will fit most if not all radiators however you will need a standard sealant application gun, a spanner or a radiator valve key and a knife in order to use the product. I used the cleaning product a week earlier though a little more complex as the system then had to be emptied and flushed. It is unbelievable how cleaning and protecting the heating system has made the house a great deal warmer with less heat having to be provided by the boiler."

Review 2 for Fernox Superconcentrate Central Heating Protector
"Bought this to treat central heating. I was a bit sceptical when I looked at what was supplied to be honest, but applicator worked really well.
To use the applicator for direct dosing you isolate a radiator, release the pressure using the bleed valve, screw in the filling adaptor, and attach the "chemical tube", open a radiator valve, inject the chemical, then re-isloate the radiator and remove the filling adaptor.
Just make sure you have got a GOOD sealant gun before using this - mine was damaged and didn't stop the plunger coming back out - dificult to use, but only due to a broken mastic gun."
