Despite the worst new housing market since the early 1990s the market for heat
pump units in North America continues to have a strong base in sales for renovation and
replacement. The market has shown a steady growth, reaching more than 2 million units in
2005 and 2006. The shipment-weighted efficiency of these products has increased
significantly over the past 20 years, driven by government regulations for minimum seasonal
performance. Ground-coupled heat pumps have begun to be sold in significant numbers and
sales of these units have nearly doubled in the past four years. The prospects for energyefficient
heat pump technologies in North America continue to be strong as public
consciousness to global warming and “green” building options grows. Heat pumps continue
to require strong advocacy and future market growth will benefit from consumer education
and awareness from government, utility and conservation groups.
