Wood pellet patio heater

Abstract

A wood pellet patio heater having a rocket stove with a replaceable cartridge, secondary air control, and a heat reflector is described. The rocket stove having the replaceable cartridge of the wood pellet patio heater provides increased efficiency (i.e. less consumption of fuel over time).
