Frequently Asked Questions
Q. How do heat pump water heaters work?

A. Heat pump water heaters capture heat from the air and transfer it into the water, rather than generating heat directly. This makes them much more efficient than standard electric water heaters.

Q. Are there any special requirements?

A. A heat pump water heater requires a fair amount of space around it (between a 10' x 10' and a 12' x 12' area). That space must also maintain a temperature between 40° and 90° Fahrenheit year round.

Q. How long do they last?

A. Heat pump water heaters last 13 to 15 years. That's longer than conventional electric water heaters, which usually need to be replaced every 8 to 12 years.

Q. Are they safe?

A. Unlike gas-fired water heaters, heat pump water heaters have no combustion byproducts, making them very safe.
