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 line.

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 and qualifications are subject to Wyoming Public Service Commission approval. Additional terms and conditions may apply.
