Electricity savings through heat pump heat recovery in buildings.

Ontario Hydro expects that about 25% of its generating plants will have retired by the year 2014. Rather than simply building new generating plants Ontario Hydro wants to diversify its approach by reducing growth in demand as well as increasing supply. Heat recovery is one of several demand-side options with potential for displacing electrical energy in buildings. Where space heating, cooling and service water heating in existing buildings is provided by electricity, savings both in electrical energy and demand are possible through heat pump heat recovery.
