Hot water cylinders

Our hot water cylinders are an energy efficient, low carbon and cost-effective way of providing hot water to residential dwellings and small commercial spaces. They are ideally suited to all-electric systems where they can be partnered with electric space heating and app control. Our water cylinders are available in two ranges, Quantum and ECS.

Quantum Water Cylinder Benefits

Efficiency and range

Ease of installation

The unit is light and easy to handle with surface mounted thermostats & sensors for simple installation

Testing and standards

It is KIWA Approved with an excellent long-life warranty on the inner cylinder

Specification and controls

The Quantum Water Cylinder can be specified with Smartphone app controllable via the Dimplex Control system* and is designed to work alongside the Quantum High Heat Retention Storage Heater


* Requires additional hardware, sold separately.

ECS Water Cylinder Benefits

Cylinder range

The ECS range of water cylinders provide domestic hot water via a direct electric immersion element or indirect coil with supplementary immersion, with the tough outer casing made from 100% recycled materials

Efficient energy consumption

60mm of CFC/HCFC free insulation minimises heat loss and energy consumption. The direct cylinder range offers fast-heating from the two 3kW immersion elements (one 3kW immersion element for the 100L). The indirect range contains an indirect coil with immersion element for sterilisation and back-up heating.

Testing and standards

The unit is KIWA Approved, offering an excellent long-life warranty on the inner cylinder.


We also offer hot water heat pumps to further reduce the energy consumption of your electric hot water solution.
