The P61/P61A will provide the exact amount of heat necessary to heat your home to the desired temperature. The temperature remains constant without all the ups and downs that happen with other brands of pellet stoves. The P61/P61A does not use a thermostat as do other pellet stoves, but rather a tiny sensing probe that sends information to the microprocessor on the stove. This information is used to feed the proper amount of fuel at the right time to keep you warm and comfortable. The P61/P61A also has a Stove Temp Mode that allows you to set the stove temperature as desired rather than the room temperature.
