What Are Unvented Hot Water Cylinders?


There are two types of unvented hot water cylinder: direct and indirect. Direct cylinders are perfect for homes without a boiler because they’re electric, and heat water using immersion heaters within the cylinder. On the other hand, indirect cylinders can be connected to your boiler to utilise its heat source.
