If you were thinking about replacing your hot water heater, you should know that new regulations went into effect in April. Now, heaters must comply with Department of Energy efficiency standards. The good news is that these regulations may create a modest savings on your utility bills.
More Efficient Hot Water Heaters
Units that use 55 gallons of water or more will require some technologies that the average homeowner is less familiar with, such as electric heat pumps or gas condensing technology. Heat pump water heaters, also known as hybrid heaters, transfer heat from the surrounding air to water. Condensing water heaters cool exhaust gases below 140 degrees where water vapor condenses into water. The heaters then reclaim the escaping heat.
