Electrical – Most heat pump water heaters require a 30 amp breaker and a 10 gage wire. If you have questions about your electrical, ask your installing contractor to walk you through how to check this. In some cases, you may need to have an electrician make some modifications before you can install the HPWH.
When estimating a total cost for the installation of a heat pump water heater, your installer should go over the current plumbing codes and permit costs with you before they begin work in your home. Make sure you understand the requirements so that your water heater is installed safely.
Also, ask your installer to help you understand the periodic maintenance requirements of a heat pump water heater.
