With propane heating stoves you get the benefit of years of intensely developed technology and will be investing in a system that has for decades heated homes all over the world.
Although propane is an oil product, made from from petroleum processes, it behaves almost exactly like natural gas (which is found in a burnable state beneath the sea and pretty much piped straight to the home). This means that almost any of the residential gas heating systems on the market can be used with propane (Liquid Petroleum Gas). Most need a simply amendment to be made to work at their best with LPG, but all dealers can easily sort this out.
Gas heating systems - radiant heat systems in the main - have been the number one choice in many parts of Europe, Asia and Australasia for decades. Up until recently the relatively cheap cost of gas (natural and LPG), combined with the generally blase approach to using up the resources of the plant, has meant that gas boilers have been fairly inefficient.
But in the last ten to fifteen years heating with propane has become much more efficient. Manufacturers have put a lot of resources into clever improvements and have found ways to recover the heat that used to be pumped outside (which gave the familiar heat haze at the outlet pipe of a gas heated home in winter). Now we are looking at efficiencies in the nineties, which is one of the things that makes propane heating systems a smart choice.
