MaritimeCamper,<br>can you post a link or show the heater you have please. Even using my smallest catalytic propane heater it uses a 20 lb tank in that time.<br>As for the lighting, sounds like you have the cheap hose or not so good propane and need to install a propane filter before the heater. You can buy them at Coleman selling stores or get the one for the Big Buddy heater. <br><br>Scarlett, you answer NO.. Catalytic is a term for how the heater works as in the type of surface that the fuel goes through to then ignite and give off heat. <br>Most now are yes, propane though in the past the most popular was the White Gas / Coleman gas though the price it through the roof for that stuff now. There were some rare kerosene catalytic heaters, but most stuck with the cylinder style dispersal method. This method was safer for the kerosene and less problematic for the end user.<br>hope that helps.
