What’s the difference between pressurised and non-pressurised steam generator irons?

The main benefit of using a steam generator iron is that the steam output is so much greater than a traditional steam iron. However, there is a difference in the way this steam is then delivered, depending whether your system is pressurised or non-pressurised. But, what does this mean?

Non-pressurised steam generator irons

Although non-pressurised steam generator irons are able to deliver similar amounts of steam as their pressurised counterparts, this steam is not powered through the iron at quite the same force as a pressurised models.

Pressurised steam generator irons

The steam from a pressurised system is forced through to the soleplate with much greater power by the pressurised boiler. This means that the steam is more powerful and penetrates deeper into fabrics.

Which should you choose?

There are many factors to consider, but this is largely down to personal preference. Both pressurised and non-pressurised steam generator irons will help you achieve excellent results for your garments, in less time than it would usually take. However, the added power of a pressurised system will make a difference to ironing times because it will relax the fibres and penetrate both layers of most garments at the same time.

One thing to consider when deciding whether to opt for a pressurised or non-pressurised steam generator iron may be your budget as non-pressurised models are ususally cheaper.

What should you look for?

Generally speaking, if a steam generator iron is pressurised, it will have a bar rating, which can be up to 5 on high-end models. A rating of 3.5 or more should make a dramatic difference to the time you spend ironing.

Usually, models which don’t have a bar rating are non-pressurised.
