When shopping for water heaters that plumb into your existing mains supply, you have to choose between a vented and unvented system. Because an unvented system doesn’t draw cold water into a separate holding tank, it takes up less room. They can also be quicker and more simple to install. They also tend to have better water pressure as they have the same pressure as your mains supply.
