As the warmer months begin to loom on the horizon, our thoughts naturally turn to relaxing days and evenings spent outside in the garden with a barbecue and good company. Even on the warmest of days, however, a chill can appear once the sun goes down, and you might be considering getting some kind of outdoor heating so you don't have to take your gatherings inside when evening arrives. Instead of a gas or electric outdoor heater, a chiminea is a great choice that not only provides an energy efficient and eco friendly source of heat, but also makes an attractive feature to gather around with friends and family.
