Good morning, sure is cold here at the house. AccuWeather says it's 20 with a wind chill of -4 and the wind is still howling at 24mph! Guess I'll have to get more propane today for the greenhouse heaters since I had to set them both on a higher setting. According to a formula I found for propane usage at 9000btu mine will use about 10lbs a day and right now I've only got two 15lb tanks hooked up to each heater (I forgot to mention that)
