Proper installation and maintenance of your heat pump water heating system can optimize its energy efficiency.
Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues. Therefore, it's best to have a qualified plumbing and heating contractor (or geothermal heat pump system installer/designer) install your heat pump.
Do the following when selecting a qualified professional:
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 building codes.
Periodic water heater maintenance can significantly extend your water heater's life and minimize loss of efficiency. Read your owner's manual for specific maintenance recommendations.
