Vented Twin Coil Solar Cylinders

From £505

Vented cylinders are the more traditional option, popular within many households as they are simpler to install and they are very effective in supplying with hot water, smoothly and efficiently. These types of cylinders can be used with most outlets whereas unvented cylinders have the disadvantage of not being compatible with some mixer taps and power showers.
