Unvented Hot Water systems allow you to have the luxury of having your hot water at mains pressure. This means that you will have high performance showers without the need for electrical pumps. They also allows much more flexibility for the location of the cylinder, as it does not rely on gravity to provide the pressure. The leading brands of cylinder are Oso and Heatrae Megaflo.
