Electric Water Heaters

What is an Unvented Cylinder?

Unvented cylinders are connected directly to your mains water system, unvented cylinders ensure copious amounts of stored hot water is available on demand and they operate at mains pressure to offer much higher flow rates.

No need for a water tank

Unvented Cylinders take up less space, giving you flexibility on where you can install.

Fast Filling Baths

Unvented Cylinders will ensure that you can fill up your bath just as quick as traditional heating systems.

Utilizes existing pipe work

Unvented Cylinders use existing pipes, this saves installing time and space.

Sun Amp Heat Battery

Saves space

Thanks to the highly energy dense Plentigrade phase change material, Thermino ePlus is up to 4x smaller than the hot water cylinder it replaces.

Saves money
Connected to the grid, Thermino ePlus can shift demand to off-peak hours. And when combined with an off-peak tariff, the battery helps save money too.

Solar PV ready
Add the Optimino ePV key and make use of free solar electricity, which can economically pre-heat water for boilers.
