I'm almost 30. I've finally found the most amazing house on almost 6 acres(in Missouri) My house is a story 1 1/2 with high ceilings and propane is absolutely KILLING ME! I filled my tank(80% 770$) dec 31 as of today I'm at 40%. My house is freezing with the thermostat set around 68. This house seems to be very well built with good insulation but I think the ceiling heights are killing me. My furnace is a beast- York 160kbtu with 6" flue pipe that works but must be 60%-70%efficient I am replacing the furnace with a 96% Daikin 90k btu. I bought a Drolet Heatpro to be the answer to my prayers. I plan on running it everyday and all day long. Anyone own one? What should I be aware of? Should be pickkng up this week and installing in the next couple.
