Heatstream

The patented heat exchanger created by Heatstream has been designed to save money, energy and resources whether for a single household or for a multi–national construction company.

The secondary hot water heating system has been designed with an 'ultra–efficient' configuration of plate heat exchangers.

Different versions of the design have been created for single household retrofits to a 'district sub-unit' which can provide the metered and hot water needs of whole communities.

Paul Dudley, ex–British Gas engineer and technical director and founder of the Hethel Engineering–based firm, has worked with his son, Heatstream director Kieron, on the project.

They say their system can cut energy consumption by 50pc compared to conventional cylinder installations.

Developed and tested over three years with support from regional agency Renewables East, it uses a patented arrangement of multiple plate heat exchangers to control water flow, meaning boilers don't need to work so hard to bring water up to the required temperature.

The business can supply distributors, developers and trade installers.

Key developments in 2011 saw the business secure investment from Sunfold Systems at the start of the year, officially launch products at Ecobuild (the world's biggest event for sustainable design, construction and the built environment) in March and submit patent applications to most global territories, to add to their UK awarded patent.

There was also confirmation of supply chain partners so nearly all elements produced are from Norfolk and engagement with a number of UK councils and national and regional house builders

And the business launched a new shower waste water heat recovery system.

The coming year will see further trials with UK councils, an increase in staffing levels and growth of the manufacturing business, among several other ambitions.
