For those who are committed to using a renewable energy source that is easy to use
and fully automated, a pellet stove or boiler can be an excellent option.
A pellet stove combines the charm of a traditional woodburning stove with the latest
technology and highest convenience. The automatic addition of fuel, remote or touchscreen
control are just a few advantages of a pellet stove.
They can even be operated by a smartphone and are fully programmable: you can program
them to turn on at a particular time of day and maintain a constant room temperature via a
thermostat and running time.
