What else should I look for when buying a hybrid heat pump water heater?
Switch to an ultra-efficient hybrid water heater. Electric hybrid water heaters, also referred to as heat pump water heaters, make over three times as much hot water with the same amount of energy as a standard electric water heater. Heat pump water heaters are the highest performing electric water heaters on the market today.
- Where will it be installed? Start by visiting EPA's Water Heater Replacement Guide to find out if a heat pump water heater is right for your home. HPWHs should be installed in interior spaces that remain between 40° to 90° F year-round, and provide 1,000 cubic feet of air space around the water heater. They generally don't operate as efficiently in colder spaces, and can cool the spaces they are in. If possible, consider installing in a space with excess heat, such as a furnace room. In colder environments with lower incoming water temperature HPWHs may need to go temporarily into a back-up standard electric water heating mode to meet household hot water use in colder months. This will increase energy use during these months. Please see the Considerations section for more details on issues to consider when installing a heat pump water heater.
- Ideal operating temperatures. Heat pump water heaters work in all weather climates, including cold weather regions. If the temperature in your region regularly falls below freezing, its best to install the water heater in a place that stays relatively warm, such as a basement or finished garage. Ideally, a heat pump water heater will be located somewhere that stays between 40° to 90° F year-round. Heat Pump water heaters also like humid places, making basements a great choice in most homes.
- Plan ahead if you can. To make your life easier, plan ahead for your next water heater replacement and you will have time to research and select the best technology for your situation before it's an emergency. Your installer may need time to order the proper model, and it may take longer to install than a standard water heater.
- Check product availability. Find out what certified models are available on the market by viewing the ENERGY STAR Product List. You will then need to visit manufacturer Web sites, call local installers, or visit your local retailer to determine who carries these units in your area, or call your plumber or contractor to see what products are available.
- Estimate the capacity you'll need. Use the gallon capacity of your current storage water heater, if you already have one, as a starting point. You can find the water heater's capacity or volume on its nameplate or yellow Energy Guide sticker. This should help you discuss the sizing of the water heater with contractors. You may want to purchase a larger unit if you have added or are planning to add more occupants to your household or a new shower, faucet, dishwasher or washer that will be in frequent use. A contractor or retail salesperson can help you decide if a larger model is necessary.
- Contact a Contractor or Manufacturer. Ideally, you will find a local contractor who can assess your site, provide recommendations, install a system, and then perform periodic maintenance. When choosing a contractor you should:
- Request cost estimates in writing.
- Ask for references.
- Check the company with your local Better Business Bureau.
- See if the company will obtain a local permit if necessary and understands local residential building codes and other regulations.
- Search for rebates. You may be able to reduce your costs by taking advantage of rebates. Be sure to review the eligibility rules before you make your purchase.
- Use the Special Deals Finder to determine whether there are rebates available for ENERGY STAR certified water heaters in your zip code.
- Don’t forget about maintenance. Like all appliances, your water heater should be looked at regularly by a licensed professional. Heat pump water heaters typically have air filters that need to be washed or replaced periodically. ENERGY STAR certified heat pump water heaters come with a 10-year manufacturer warranty for extra peace of mind. Owning a heat pump water heater requires no special tools or know-how.
- Extra Benefits of Heat Pump Water Heaters. In addition to saving over $300 a year in energy costs, heat pump water heaters come with benefits that you will not find in a standard water heater. In hot, humid climates, heat pump water heaters can help cool and dehumidify a room. In cold climates, they can help dehumidify a cold, clammy basement.
- Consider other measures that may also save energy. If you are in the midst of new construction or home remodeling project, you may have come across other proposed approaches to water heating. Under the right circumstances, these technologies can save significant amounts of energy.
