The plumber recommended I use this product based on his many years in the trade. Very easy to use, took seconds to get it into the hot water system, via a radiator. There was enough in one can for my 8 rad's, but not sure how many it would cater for.

Very easy to dose the system via the radiator bleed valve, following the simple instructions. Only problem was the spray of water / inhibitor when removing the nozzle from the bleed valve. Would recommend covering with a towel when removing but I will depressurise the system next time I do it as ther is some loss of the inhibitor .

Used this after having the rads off for decorating. I injected the product in through the towel bleed plug rail in the bathroom. It goes in in less than 2 seconds. No mess and no fuss. Just refit the plug and close the bleed screw. Recharge the system and you are protected.

Perfect for a pressurized system for filling through the filling loop - just turn off cold water supply, unscrew filling loop from cold water supply, attach Fernox adapter to filling loop, attach Fernox bottle to adapter, open valve to boiler, pull trigger and it's in. Close valve to boiler, detach empty Fernox bottle, reattach filling loop to cold supply. Fairly straight forward and 5 minute job at most.
