How does a heat pump differ from a gas pool heater?

It moves heat from the air into the water instead of burning fuel, so it runs more efficiently and usually costs less to operate. The trade-off is slower heat-up and weaker output in cold air.

Will it work in a cold climate?

Nirvana says the unit is designed to perform in all U.S. climates. Output still falls as air temperature drops, so it heats best in mild to warm conditions.

The unit uses noise-reduction technology, so it runs quieter than many conventional heat pumps. Actual sound depends on placement and surrounding surfaces.

What size pool does the NE50 suit?

Match the heat pump's output to your pool volume, surface area and cover use. A covered pool in a warm climate heats faster than an uncovered one in a cool climate.

What is included with the heat pump?

The unit ships as the heat pump itself; plumbing, electrical work and installation hardware are handled by the installer. Confirm the electrical requirements with your installer before buying.
