Tech Highlight:

Heat Pump Water Heaters

Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters, saving you money on your energy bill. Learn more about them and available rebates below. 

Your home may need an electrical panel upgrade to install a heat pump water heater. Ask a BayREN Home Energy Advisor about your situation and browse electrical contractors for more info.

Heat Pump Water Heater


Heat pump water heaters draw heat from the ambient air in your house to heat water. A refrigerant fluid absorbs the extracted heat and undergoes compression to increase its temperature. The heated fluid then transfers its heat to water in a storage tank. Heat pump water heaters are extremely efficient, can save you money on your energy bill, and are subsidized through tax credits and rebates that you can apply for.

Tankless Water Heater


On-demand electric water heaters are tankless water heaters that differ from traditional electric water heaters because they don't require a storage tank. Instead, when a hot water tap is turned on, cold water flows into the heater and is heated by an electric element. They are available in a range of sizes to supply water to an entire house or at a specific point of use. Click here to learn more about tankless water heaters.




Energy Savings Tool: Water Heater Tank Wrap


Also called a tank blanket or jacket, water heater tank wraps are an extra layer of insulation that can enclose an oil, gas or electric hot water tank. They are typically made with fiberglass insulation with paper backing, but other insulation types such as denim and mineral wool can also be used.
