Water Heaters

What Is Heat Pump Water Heater?

Definition

A heat pump water heater uses the same heat-moving technology as a space-heating heat pump — pulling ambient heat from the surrounding air to heat water — instead of a standard electric-resistance element, using roughly a third of the electricity of a conventional electric tank for the same hot water output.

Why it matters for your home

Energy Trust of Oregon applies an instant discount up to $1,200 (installed through a participating distributor) or about $1,000 on DIY retail models — applied right on the invoice, no rebate paperwork required.

What to do about it

Ask whether the discount applies at the point of sale on your specific model before assuming you need to file separate rebate paperwork — for this program, you usually don't.

Money term — the details

How much less electricity does a heat pump water heater use?

It typically uses roughly a third of the electricity of a standard electric-resistance tank for the same hot water output, since it's moving ambient heat rather than generating all of it electrically.

Does it need more space than a regular tank?

Usually yes — it needs clearance and a reasonable volume of surrounding air (often a garage or utility room) to draw heat from, and it can slightly cool that space, which matters if it's installed in a small closet.
