Fernox

Great company that has been around a long time. Fernox is my go to brand for water treatment and testing. Including the test kit which is sent of for analysis. I use this service when I powerflush a heating system.

I have been a heating engineer for over 20yrs and highly recommend this manufacturer and their products as I have never had a problem with anything they make from cleaning agents to inhibitors to my power flusher.

Great chemicals by a reputable brand, and recommended by boiler manufacturers too! Everything a gas engineer needs, from cleaners & leak sealers to inhibitors, I recommend the whole range!

Great quality brand, been around for years, does exactly what is need to clean and protect you central heating system and radiators , also protects your boiler as well , must have for any heating system

Top quality chemicals from the super f1 inhibitor to the ultra reliable f4 leak sealant or if you need system cleaners F5 is really good but needs to be left in for a week or two , it never lets me down

Good quality products, I mainly use their consumables over other similar ones as it’s what has worked for me in the past.
Inhibitors and joining compounds have all been great.

I sometimes do copper pipe soldering, it is very important to get the tube clean and then flux,
Fernox make an active flux that is brilliant.
I used to use traditional flux but since a plumber recommended Fernox active flux to me my soldering has become much better.
Today l was soldering 28mm copper tube and the flux made the job very easy
I would definitely recommend

My go to for chemicals wouldn’t touch adey or sentinel
New f8 is excellent use a lot of f3 and f5 bit slow but leave in system for a while and does a great job

Superb quality chemicals and between fernox, ADEY & sentinel I wouldn’t put any other chemicals in my heating systems . Prefer the ADEY filters to be honest but the fernox filters are still v.good

My first choice of system chemicals. I find they do exactly what they are supposed to and not too pricey. The range they offer also means they always have a chemical you need. The brass omega filter is also good.

Use various fernox chemicals daily for work on central heating systems, f1,f3,f5 especially and never had any issues with them, easy to put into the system especially as the express tubes that go into a radiator bleed valve. Well worth using if your protecting your radiators from corrosion.

The product does what it says on the tin the cleaner is amazing when using a Magnacleanse it's amazing how much muck you can get out of a system

Good filters and work really well for the money the cleaner and inhibitor easy to use but fiddle to use but very good value for money easy to fit in tight space

Speak to these a lot on Instagram always there to help pleasure working with them the water treatment product are 10/10 omega filters don’t only look but but extend the life of your boiler

Der ox is not for me, filter seals are rubbish, I used them before Adey and I am glad I have stuck with Adey.
Everything about Adey is better in my opinion

Brilliant items used lots of there stuff cant fault it and not bad priced either would recommend to any to use in both domestic and commersial

I love the Fernox range, good quality gear for the industry, over the years I have tried a few inhibitors and cleaners, I always find the range offered by Fernox has the edge, whether it’s the inhibitor, cleaners or for the stubborn growth in header tanks, their biocide. Some of the products are a little more expensive, in reality I don’t mind paying a premium it’s never let me down.

Have been using fernox inhibitor for over 20 years. Have found it better than a few others on the market. Their new filter is of a good quality build compared to the early models, these were very poor and do leak. Their product range is improving all the time and it is worth reading what is required before purchasing their products.

Got the powerflush machine and it works a treat. Also their chemicals are good. Never had a problem with any of them.

The line scale remover is amazing. Works really well

I have been using Fernox for years. Have been tempted at times to go cheaper but then always heard bad results so glad I never did. Fernox have always been so reliable and excellent quality. Now use the postal service for water quality testing and it is superb. Gives a good peace of mind. Looking forward to trying out their quick test strips as well.

I have used fernox chemicals and accessories on central heating systems andvghe do a good job. Slightly more expensive than other brands. My only issue is with the TF1 filter where I would often find the rubber seal to persish and would replacing too often.

Chemicals price on the high end but seem to do a good job. Heating filters have improved massively from the original TF1 disaster, would use but not my 1st choice due to price

I use fernox products daily in heating systems and have to say that I have never had any trouble with them. So based on that would be more than happy to recommend

Fernox make some good products, I’m a fan of the F1 inhibitor, f3 &f5 cleaners I’ve been using it for years and never had any problems, used on a clean system it seem to keep erosion level very low, much better then some cheaper Chemicals

Being a plumber i get asked whats best to protect my heating system I always say to top systems up with fernox inhibitor. Simply The best stuff out there, also the solid chrome metal omega system filters are quality one of the best as well

My personal filter of choice is the omega. It’s smart looking, strong build quality and very effective at catching dirt in the system. I try to clean my new installs as best as possible but knowing the omega is there as the best filter on the market gives me good piece of mind.

My go to brand for both heating chemicals and also filters love the ease of fitting of the omega and the choice of valves or slip coupling option to suit various installs crecently found their online training and enjoyed it

The customer services is second to none , great range of products that meet my expectations , the Tf1 nickel omega filter is so easy to fit and service

Been around for years and they seem to know their stuff, there chemicals do as they say they will most of the time, with chemicals and systems there will always be the odd one

Have a good range of chemicals and very good quality. Have used their tf1 omega filter which is one of the best products on the market great quality product.

Good quality products and competitive prices and do a great job. Have used a good few products from them and never had any issues highly recommended

unless the supplier is out of stock these are the brand i go to after changing radiators or installing new ones for clients. product range is reliable and of a good sound quality you can use and leave the job knowing they will do as expected

Since the release of the omega filter it is the only magnetic system filter I recommend to customer. Proven to work and pick up debris in heating systems that some filter’s just won’t. It comes in two models, one with and one without isolation valves, it’s more robust than its predecessor (TF1) smaller in size yet better performance. There chemical range is decent enough and is one of three that’s recommended by nearly all boiler manufacturers.

Pretty much the only product I would use, have used similar brands in the past but none seem to offer the same protection, haven’t the F1 express yet just the F1

I used Fernox's tf1 filters and they weren't too bad. but now I love their omega magnetic filters. very solid and robust. happy to recommend them to. my customers. Also the training. center near West London is awesome.

Nothing comes close to the Fernox cleaners or inhibitors. I’ve used Fernox for years and never had any complaints. I’ve tried others but nothing compares. Would highly recommend.

LSX is a great product I no a few plumbers who use it every day. We tend to only use it for waste pipe leaks and such but really works great. Www.Glencoplumbing.co.uk

I have used Fernox cleaners for years, best on the market. I keep a small stock on the van. I have tried others but nothing really compares.

Fernox tf1 filter without valves is my current go to filter . The solid brass construction gives this product a solid robust build quality . I recommend if you do fit these filters buy the flushing adaptor it’s only cheep do a great investment

Fantastic different ranges. Cleaner gets me out of trouble if I don’t have a spare part for a boiler until the part arrives. Did have a little hiccup when I sent off for a system check and they didn’t enter my email address in correctly apart from that they’ve been great.

I have used Fernox products for over 20 yrs, the inhibitors and cleaners are excellent, I have tried others but noting comes close to Fernox.

Best brand out there in this market! I wouldn’t use anything else. The cleaners do actually clean, unlike some I’ve used in the past.

Without a doubt the best selling cleaner and inhibitor there is alot out there and cheaper but not as good product and fit for purpose

This is my go to brand in water treatment products, good quality and work every time never have problems with the product. I do like LSX as a jointing compound on sanitary ware makes a great seal.

Brilliant, does what it says on the tin and have a wide range of products. Have been using fernox for a while now and will continue to do so.

The omega is a good quality and affordable primary filter (now they give you an adapter to use the chemicals with it). The range of chemicals are second to none and do exactly what it says on the tin.

Great range of products With a decent customer service that can help you with any questions and queries

Does what it says on the tin, no complaints really as it’s doing what I intended it to do when I purchased this product

we only used fernox from years ,F1 and F5 is the best for central heating treatment , very good quality and great support , fernox omega filter solid brass is now very popular

We've used fern on chemicals for years. Can't say that. Notice any difference between these and others (I'm sure they are a all the same but in different bottles haha) however i continue to use fernox as the brand name is something that is recognised

We only use Fernox chemicals! F1 is the Fn bees knees when it comes to inhibitor. I think the filters could do with thicker washers as the current ones are too thin and the filter moves on them. Also they should put the chemical stickers on the underside of the lid, not on the exposed outside

Fantastic chemicals and great customer support. Products are found in every merchant and in my option set the standard that others try and meet.
Wasn't very impressed with the original TF1 filter, had loads of issues with them leaking, even had one where the plastic split and the valve dropped off. Have just replaced another this week, which wouldn't stop leaking, with the new omega filter. First impression is that it's a very good design, easy to fit and seams solid. Time will tell though.

Always had really good support from these guys. Chemicals always work well and had a great service whenever we had any issues

Brilliant Stuff Best going in my opinion wouldn't use out else
Highly recommended To other people Customer service great too

I was always an Adey Man until I see the support offered by Fernox and their reps. All queries answered asap and great products to go with it. The new omega filter is excellent

The recently launched Fernox Omega filter has quickly become my first choice filter option. Solid brass, great capture ability, easy to service & add Fernox chemical inhibitors...
