Not sure if your water heater is electric or gas?

Here's how to tell:

First, read the label to see if it gives indication.

If you can't figure it out from the label, take a look at the pipes.

  • Gas water heaters will have 3 pipes: gas in, water in and water out. The gas line, often at the bottom of the unit, will have a shut-off valve on it. This differentiates it from an electrical conduit.
  • Electric water heaters will have 2 pipes: water in and water out with an electrical conduit or electrical wire feed lines

Please note: Gas lines and electric wiring can be extremely dangerous. Be sure to contact a plumbing professional if you're unable to discern the type of water heating system in your home.

Please see Incentive Application for a list of required documentation and additional terms and conditions. Incentives are subject to Idaho Public Utilities Commission approval and may change with 45 days notice. Additional terms and conditions may apply.
