Lava recently introduced their pyramid-shaped heaters. The big advantage, other than its striking European-designed looks, is ambient heat that radiates from the sides for better 360-degree warming. To achieve this safely, borosilicate glass tube contains the propane-powered flame while a wire screen on the outside remains safe to touch. Made from powder-coated steel (available in five colors) , the heaters will endure rain, snow and other inclement weather and are easy to use and assemble. An electronic ignition makes it a cinch to fire up the propane tank enclosed in the base (it can also convert to natural gas), and you can even operate it by remote.
