Two-stage heaters, also known as variable-speed and dual-stage units, are a newer type of heater that can operate at two power levels. Conventional heaters are either on or off. A two-stage heater can operate at full output or at a more efficient low-power option.

How Does Two-Stage Heating Work?

A two-stage heater looks just like a conventional heater, and you use it in the same way. It will operate at full strength when it’s freezing outdoors, so your home is comfortable. When temperatures are moderate, it will operate at a lower energy level.

A two-stage heater will automatically switch between its two power levels based on need. You don’t have to make any adjustments to it or your thermostat.

Costs Less to Run

When operating in low-power mode, a two-stage heater uses less energy. Even though it runs longer when in this mode, you’ll save money on your utility bills. You’ll notice the most savings in fall and spring when outdoor temperatures are mild.

Quiet Operation

When operating in low-power mode, a two-stage heater is quieter than when working at full power. You won’t hear the kick sound when the heater turns on, for instance.

Provides More Comfort

Conventional heaters quickly heat a room, turn off, let the room cool down and repeat the cycle. Two-stage heaters keep a home more comfortable as they keep the indoor temperature within about 1 degree of the thermostat setting.

Improved Indoor Air Quality

Since a two-stage heater runs longer, there is more time for the filter to trap dust, dirt, and allergens. The result is improved indoor air quality.
