Gas water heaters are the second largest users of natural gas in homes after gas furnaces.
Heat pump water heaters use electricity to extract heat from the air and compresses it to transfer to the water through condenser coils. The heat pump system works like your refrigerator in reverse and is highly efficient.
Depending on the age of your current water heater, it is a good idea to plan for a heat pump water heater when the gas water heater breaks down. The typical lifespan for water heaters is around 10-15 years. Installing a heat pump water heater may require installation of new outlets that can be hard to complete on short notice. Planning for a heat pump water heater ahead of time will enable you to effectively switch to a heat pump water heater when the gas water heater breaks down. If your gas water heater is old enough, it might make sense to make the switch now instead of waiting for it to break down.
