Storing propane outside in cold winter temperatures can decrease the efficiency of a propane tank, according to Powerblanket. The company’s propane tank heater offers a simple, economical and efficient solution to keep propane tanks from losing pressure in cold weather. The propane tank heater wraps propane tanks in a durable vinyl blanket that spreads electrical heating evenly throughout the surface area of application. Powerblanket says the technology can save users money by optimizing gas and material usage. Additionally, the heater helps to eliminate unnecessary cylinder refills in cold weather. The propane tank heater can maintain pressure and efficiency on almost any size or shape of propane tank. The company adds that ready-to-ship options of the propane tank heater are available for common tank sizes, and custom solutions can ship in one to two weeks.
