About this product
The Fernox 62455 Super Concentrated F3 Cleaner is a powerful liquid solution designed to optimise the efficiency of your heating system. Formulated by Fernox, this concentrated cleaner effectively removes sediment and limescale build-up that can accumulate over time, restoring performance and ensuring your boiler operates at its best. It’s an ideal choice for homeowners and landlords maintaining multiple heating systems – capable of treating up to 100 litres of water.
This super concentrated formula offers significant value, with a single 265ml bottle sufficient for tackling the needs of up to twelve heaters. The citrus scent provides a pleasant odour while it works its magic, and the pH-neutral composition makes it safe for use on most common system metals. This product is particularly useful where scale and sludge have accumulated, helping to restore heating efficiency and prevent further build-up.
The Fernox F3 Cleaner’s concentrated nature means that only a small amount – 265ml – is needed to treat a substantial volume of water, up to 100 litres. However, for particularly badly sludged radiators, it's recommended to use this cleaner in conjunction with a system flush for optimal results.
This liquid treatment is packaged as a single 265 ml unit and is perfect for those seeking an affordable solution to maintain their heating systems. Please note that standard Amazon returns terms apply to this product – refer to Amazon’s website for details on how to proceed if necessary.
