Alpacas are raised for their soft and luxurious fleece (sometimes called fiber). Each shearing produces roughly five to ten pounds of fleece per animal, per year. This fleece, often compared to cashmere, can be turned into a wide array of products from yarn and apparel to tapestries and blankets.
1 gallon of propane is about 90,000 BTU/hour. A 20 lb tank holds a little more than 4 gallons. My patio propane fireplace is 60,000 BTU. At full blast, a 20 lb tank will last about 6-7 hours, which is really close to the calculation. 32 people found this useful.
I just had a leaking power vent gas water heater replaced after a month short of 10 years. It's a rental. I asked the tech if they should last longer than that and he said 6-10 years is normal in a hard water area like mine. installed a 30 gallon fast recovery gas water heater with a standing pilot 30 yrs ago, my son lives there now and its still operating. This is a Sears/Kenmore model. I also replaced a boiler at the same time and that needed new burners because it did not have a standing pilot.
