Attendees of this course will learn the benefits of water heating technologies, for examples:

• Greenhouse gas (GHG) emission reductions from the building sector as a result of displacing natural gas and propane combustion water heating.
• Increases in electrical efficiency as a result of replacing electric resistance water heaters.
• Utility bill savings for ratepayers as a result of technology efficiencies and the ability to shift electric consumption to parts of the day when renewable energy resources are abundant and electricity prices are lowest.

Attendees will be familiarized with the various types of water heaters:

Conventional storage water heaters offer a ready reservoir (storage tank) of hot water which is adequate for everyday use. In some instances, however, such as when simultaneous usage of hot water occurs, or when there is a longer durational need for hot water.

• Heat pump water heaters move heat from one area to another instead of generating heat directly to provide hot water, resulting in high efficiencies and significant cost reductions.
• Solar water heaters use the sun to heat water, reducing energy costs for homeowners.
• Tankless or demand-type water heaters heat water directly without the use of a storage tank. This type of water heater is designed to provide a sufficient supply of hot water without running out, when adequately sized.
• Tankless coil and indirect water heaters use a home's space heating system to heat water.
