University of Waterloo to cut Water Heating Costs by up to 30% in Townhouse Community Project

(Waterloo, Ontario 1.14.08) RenewABILITY Energy Inc, manufacturer of the Power-Pipe® Drain Water Heat Recovery (DWHR) system, Reid’s Heritage Homes and Union Gas announced they recently complete the installation of 250 Power-Pipe DWHR Systems at the University of Waterloo, Columbia Lake Village North Community (CLV), Ontario. Now completed, the Power-Pipe® DWHR Systems will reduce water heating in unit showers by 20% to 30%!

‘While you may or may not be familiar with Drain Water Heat Recovery (DWHR) or the Power-Pipe®, it’s simple, affordable, practical, effective, proven, and scalable turnkey heat recovery technology that dramatically reduces water heating costs,” noted Ron Salisbury, Manager- Home Performance at Reid’s Heritage Homes.

‘Reid’s Heritage Homes which partners with the University of Waterloo in maintaining the University residences has been installing DWHR systems in many Energy Star and LEED Certified residential communities and retrofit projects in London, Guelph and Port Elgin. DWHR simply pre-heats cold intake water with warm or hot drain water prior to entering a standard water heater or on-demand water system in residential and multi-residential applications – reducing water heating costs and energy usage significantly”.  ‘While that may not sound like a dramatic factor, Natural Resources Canada reports that water heating is the second largest energy use in Canadian single and multi-residential properties! So the 20% to 30% reduction in water heating which translates into a 6 to 9% reduction in total energy usage is actually quite sizable.  In short, we are convinced DWHR represents a new and very promising energy savings potential for Canada’ residential sector, added Ron Salisbury.

In relation to the climate, the pollution reduction numbers are even more staggering.  The typical Power-Pipe® DWHR unit will reduce GHG emissions by about 200kg/person/year when displacing Natural Gas water heating.  In a 4 person home, that amounts to a reduction of almost one ton of green house gases per year per Canadian household!  For the University of Waterloo units the impact will be even greater noted University of Waterloo graduate and RenewABILITY Energy Inc President and CEO Gerald Van Decker.

The University of Waterloo, Reid Heritage Homes, and RenewABILITY Energy are planning a ribbon cutting ceremony in mid to late January at the University Townhouse Community.

The technology was developed and is manufactured in Canada and can be viewed on YouTube at:
