Choosing the right electric hot water system package depends on your installation needs, household size, and whether additional electrical work is required. Use this guide to compare package levels and find the best fit for your home.

Selecting the right package helps streamline installation, but we understand that needs may change, and that the purchaser isn’t a plumber. We’re flexible and can make adjustments, such as upgrading to the next package as needed.
