Better Buildings Alliance Commercial Heat Pump Water Heater Specification
BBA has developed specifications for multiple technologies:
The Better Buildings Alliance (BBA) has released a specification for commercial heat pump water heaters that outlines energy-related product requirements. Purchasers can use the specification today to ensure they are procuring a high-efficiency, high-quality product from manufacturers.
An older, electric resistance water heater operated in a building with a hot water demand of 500 gallons a day, 365 days a year can cost over $3,500 each year in electricity costs. A new heat pump water heater that meets the BBA specification would use 70% less energy and could save $12,500 over 5 years. If all commercial electric storage water heaters in the U.S. were replaced with heat pump water heaters per the BBA specification, businesses would save 15 TWh of energy, or about $1.5 billion in energy costs per year.
If you are interested in saving energy and saving on your business's utility bills consider using this specification when procuring a new heat pump water heater.
How to Use the Specification
STEP 1: Answer the following set of questions to determine if a heat pump water heater is right for your building. If you answer "yes" to the first two questions and at least one other question, adding a heat pump to your electric or gas storage water heater is likely to be a value-generating option for your building.
- Do you use a storage water heater in your building?
- Does your water heater have a nominal input rating of more than 6 kW (20,473 Btu/hr)?
- Are you constructing a new facility or performing major renovations that involve changes to the water heating system?
- Is your current electric storage water heater more than 10 years old?
- Are your local electricity costs high, or are you concerned they will rise in the near future?
- Are you seeking an ENERGY STAR® label or a green building certification?
STEP 2: Find financial incentives you may qualify for on the Database of State Incentives for Renewables & Efficiency website. Then calculate the financial savings you could achieve by switching to a high efficiency water heater.
STEP 3: Download the BBA water heater specification template, and develop a customized specification to reflect your specific site's needs.
STEP 4: Send your customized specification to one or more manufacturers to get quotes.
STEP 5: Purchase and install a heat pump water heater and start saving money and energy!
