About Zenex

Company Overview

Zenex Technologies Limited was established in September 2003 to develop a range of technologies that would address future energy needs by improving the overall efficiency of domestic and commercial central heating boilers and hot water systems.

Zenex is a private limited company and since the company was set up, over £3 million has been invested in developing a range of ground-breaking energy-saving technologies.

Zenex has fully-commercialised a range of products including the Zenex GasSaver; the Zenex Superflow, and the Zenex Superflow with Renewables. It also has a number of other products currently under development.

Zenex has registered a number of different patents on its products and the performance of these products has been independently verified by impartial testing bodies such as TUV NEL.

Zenex technologies are now recognised as new energy saving categories within UK Building Regulations.

In addition, the Energy Saving Trust (EST) now recognises the Zenex GasSaver under its Energy Saving Recommended scheme and has established a new product endorsement category - "Passive Flue Gas Heat Recovery Devices and Systems".

The Zenex GasSaver has also been awarded the Waterwise mark in recognition of the water savings that can also be achieved when using a GasSaver device. This is because the Gas Saver means a combi-boiler delivers usable hot water much more quickly and so there is therefore much less water wasted as the water comes up to a useable temperature.
