Water Heating
Global revenue in 2011 for residential water heating in high-efficiency homes was just under $1.5 billion, $1.1 billion of which was in the United States.
Advanced water heating for residential or commercial uses includes many options, ranging from more efficient conventional water heaters to those using renewable sources such as solar or biomass. This analysis examines only residential water heating as specifically used in high-efficiency homes, including efficient electric, natural gas, solar, and tankless water heaters. This does not include high-efficiency water heater units installed in residences other than those defined as high-efficiency homes, making this a very conservative view that understates the overall use of high-efficiency water heating in regions outside the United States.
Global revenue in 2011 for this slice of the Water Heating subsegment was just under $1.5 billion, $1.1 billion of which was in the United States. Although retrofits are included in this definition of high-efficiency homes, new construction is a key revenue driver; hence, the overall opportunity has been impacted by the recent housing recession. Despite this, revenue growth between 2011 and 2012 is estimated at just below 6%.
