Water heaters are the under-appreciated heroes of the household – and also a big energy user.
Cut costs by up to 60%
If you have an electric water heater, you could save hundreds of dollars every year by switching to a heat pump water heater.* They’re the most efficient water heaters you can buy.
Most qualify for instant discounts from Energy Trust of Oregon, which could make your final cost lower than a standard water heater. And be sure to check for any special offers that could save you even more.
Sizing is important to efficient operation. Use this guide to help select the right heat pump water heater for you.

Heat pump water heaters:
- Are slightly larger than standard electric water heaters
- Sound similar to an air conditioner (sound level varies by model)
- Produce condensate (water), which is drained or pumped out of the home
- Offer maximum energy savings when located in an unheated space such as a garage
- Generally require a 10’x10’x10’ room or space to allow sufficient airflow. Tier 2 and 3 models (see below), which use ducting, can be installed in confined spaces
