Good things come in small packages, just like the Enviro Mini. It has a built in hearth pad and a heavy duty heat exchanger. The Enviro Mini is a modern looking european style pellet stove. It produces 30,000 btu. or zero with the optional thermostat and has a maximum burn time of 36 hrs. Thermostat ready, it is quiet running with a cushioned auger, can be operated without the convection fan, and you have the option to put the combustion blower outside your home. It has a large ash pan that only needs to be emptied once a week and a hopper that allows thirty six hours of burn time on one fill.
