Just as with everything in life, no matter how many positives there are, there are always going to be some negatives. Fortunately for mild steel radiators, these are few and far between. The major downside of mild steel radiators is that they are prone to rusting from the inside, especially if you have a combi-boiler or mega flow (closed) system in your house. This is why they typically come with shorter guarantees than the other materials. It’s not all doom and gloom though. Internal rusting can easily be prevented by making sure that your boiler is regularly serviced and an inhibitor is added to the system. This prevents rust from forming in your water system and gathering on the inside of your radiators. As long as you do this, you can expect a mild steel radiator to last a lifetime.

Stainless Steel

Stainless steel radiators share many of the same properties as mild steel radiators. They’re strong, they come in an ever increasing array of designs, and they are built to last. One difference with mild steel radiators, however, is the resistance to rust and corrosion of a stainless steel radiator. Rusting from the inside shouldn’t be an issue for a stainless steel radiator, although it’s still definitely beneficial to keep your system topped up with an inhibitor just to be safe. After all, a radiator rusting from the inside because of rust in your water system will not be covered under the manufacturer’s guarantee.

Thanks to the anti-rust, anti-corrosive and anti-stain properties of stainless steel, however, most stainless steel radiators come with a lengthy guarantee – typically between 5 and 25 years. Anti-rust properties don’t mean that are 100% rust resistant though. If you have a habit of leaving sopping wet towels on your towel warmer or radiator, you may find rust forming on the outside of the radiator. That is why we advise against putting wet towels on radiators and heated towel rails; after all they’re called heated towel warmers, not towel dryers. If rust does form on your stainless steel towel warmer, however, this shouldn’t alarm you as it’s not actually the radiator rusting and it should be quite simple to wipe off.

Stainless steel radiators do have their downsides, but they are minimal. When compared to mild steel radiators they are considerably more expensive, although it’s still possible to pick one up for around £200. When you consider the fact that it will most likely last a lifetime and require much less maintenance, the initial extra outlay is worth it if your budget allows. There are also fewer styles and fancy finishes than mild steel radiators, although with more manufacturers focusing more of their time on stainless steel radiators, that is likely to change.
