Rated 5 out of 5 by from Fernox f1 I have previously used another brand but having read the rwviews i have now decided to swap to fernox products. Good value abd readily available from ny local screwfix outlet. Just drained out a bucket full of the existing water, added the bottle contents to the jeader tank and topped up again. Easy peasy.

Rated 5 out of 5 by from Well worth the effort with F3 We have had a combination central heating system (inc new pipes) installed new 18 years ago. It has been serviced every year by a huge/ well known heating firm and has had various parts maintenance in that time. However, in over a decade of service from the well known heating firm, I can never recall a boiler service where the heating water was ever drained and replaced or inhibitor added. We also have had a magniclean device installed on the strong advice of the heating firm. Every engineer visit is accompanied with a brow beating and hard sell of products, the latest being a power flush at over £700. The radiators all seemed to work fine with only one top radiator being cooler than the rest. We researched heavily on power flushing and alternatives. An independant heating engineer recommended initially avoiding the power flush and look to use Fernox F3 Cleaner and Fernox F1 protector. Various reputable online heating forums also gave similar guidance. We decided to go down this route. We have 13 Radiators and used 1 litre of Fernox Cleaner. We isolated the boiler electric and gas and drained down the system via a drain point and hose, some signs of discolour and iron oxide. I guessed the magniclean must be working well. We filled the system slowly, bleeding the radiators on the way up and putting 1 litre of cleaner in via the towel radiator top blanking nut. After this we ran the system for a week as per the instructions to clean the system and seemed to notice the radiators did get hot noticeably quicker and the boiler did seem quieter. After a week, we isolated the boiler gas and electric and drained the system down again. The heating water discharged was heavily discoloured after cleaning for a week and a fair bit of iron oxide was present. We removed the top radiator and flushed this through outside with a hose and this released even more black sludge. We left the top radiator off and refilled the system to rinse the cleaner and residue out. While it was full we opened the top thermostat valve and lock valve into a bucket and washed out some more sludge. We then drained out the system and cleaned/ rinsed the magniclean. The top radiator was replaced and the system emptied of the water used to rinse it. By this time, the heating water discharged was a lot cleaner. The process did result in clearing out a whole lot of black slurry. We then refilled the system for the last time, and this time added 1 litre of Fernox F1 Protector at the top towel radiators, bleeding the system as it filled up slowly. Before we started the heating, we balanced the radiators, having watched a few videos on YouTube on how to do this and get optimum flow around the system. Having switched the heating back on, it is running quieter and heating quicker, the balancing has helped with preventing unevenly cooler radiators, and we are pleased. The Fernox products claim a 15% reduction in gas for heating, but I can’t verify this but would say the system does heat quicker and is burning for shorter periods, so it may be true. Overall we feel that the system must be healthier now for this treatment and are pleased so far and would recommend this. If you do go down this route, allow yourself 2 whole days each a week apart. 1 day to add cleaner, 1 day to rinse and add protector. It won’t take you all day, it is time consuming but well worth it. We will definitely repeat this exercise to keep the system clean and protected.
