I just heard about an interesting new product the other day. Energy Alternatives LLC announced the introduction of its Greenward Ridge Vent. According to Ted Poulos, Vice President of Energy Alternatives, the patent-pending design harvests ambient hot attic air as it escapes through the ridge of the roof. The thermal heat is used as a form of renewable energy to heat the incoming water for the home’s hot water tank. Poulos noted the company has partnered with Benjamin Obdyke Incorporated to aid in the development of the product.
“We make it possible and affordable for every homeowner to have a direct impact on their carbon footprint while ventilating their attic” said Kevin B. Scott, President of Energy Alternatives.
The company describes the product this way: “The Greenward Ridge Vent System provides homeowners an inexpensive method to heat their incoming water into their hot water tank by reusing the heat in their attic. As the hot attic air escapes through the ridge of the roof, it passes over flexible tubes contained in the ridge vent material. These tubes carry an environmentally friendly water/corn based glycol solution that gets heated by the escaping hot attic air. A circulator pump pushes the hot solution in a closed loop into a hot water storage tank where it heats the incoming city or well water.”
We plan to profile some installations in a future issue of Roofing Contractor.
