A Crap Way to Recover Heat

30 May 2014 | Updated 01 January 1970
A company specialising in renewable energy technology and waste water heat recovery systems that deliver a sustainable energy source to commercial and residential multi-occupancy buildings, is coming to the UK market. Its USP being a sewage heat recovery system.

SHARC Energy Systems is pioneering the introduction of environmentally friendly options for heating, cooling and hot water by bringing to the UK technology developed by one of Canada’s major providers of sustainable alternative energy source systems; International Wastewater Systems Heat Exchange Systems Inc. (IWHES), based in Vancouver.

The IWHES system is claimed to be the first sewage heat recovery system to market in Canada and is said to be suitable for commercial and multi occupancy residential properties and buildings, e.g. hospitals, schools, student accommodation, leisure centres, retail developments, shopping centres and multi-site and occupancy residential developments, whether as a new build or retrofit installation.

The SHARC Energy System uses a building’s waste by taking the raw sewage, treating and cleaning it, then using it to create an alternative heat source.



Displays include real-time readouts and the system incorporates software to monitor and predict usage trends and issues. The system’s heat pumps operate at an average 400% percent efficiency and heat water to an average 210C at flow rates in the region of 200 gallons per minute. It can be fitted to buildings from 100,000ft2 upwards and will recover and recycle all waste water to provide a constant supply of even temperature water and heating.

SHARC Energy Systems is the trading name of IWWS (UK) Limited and the company has its official UK launch on the 3 June 2014 in the East Midlands.

“The SHARC Energy waste water technology utilises a clog proof raw sewage filtration system and heat exchange technology that conducts the heat from untreated wastewater,” explained Russ Burton, CEO, SHARC. “Natural resources are steadily depleting with more than 60% of the world in fuel poverty. It is imperative an alternative to the traditional fuels is embraced as we face ‘carbon crunch’ which is set to be one of the biggest challenges of our generation.”
