Have you ever been on holiday abroad and wondered why the showers were so good? The answer is that in most of the developed world the way hot water systems work is different to those traditionally found in the UK. These systems are run directly from the mains water supply. The good news is that these systems are also available here in the UK.

These systems are known as 'unvented' because they are sealed from the atmosphere. The technology they use is not new. In fact an Englishmen called Thomas Hawksley invented them in 1861. But they were not adopted in the UK due to the unreliable mains water supply. Also at that time there was an advantage in having stored water in the loft. For some time now it has been possible to install and enjoy the benefits of unvented hot water systems in the UK.
