Hi. I have a '78 Sovereign. The Forced Air Furnace works fine. It also has a Catalytic heater the former owner swears by. He said the furnace used too much propane and suggested I use the catalytic heater. I tried it and darned near froze do death when the temperature dropped to 20 degrees. What's too much? Does anyone out there know whether the furnace rips through propane or is just a moderately heavier user than the catalytic? When it is really cold and you have to have the windows open for the catalytic heater all night it seems to about balance out. Any advice? JLD
