An Energy Star propane tankless water heater has high efficiency levels—between 83 to 94 percent on average. Hence, a tankless water heater is approximately 60 percent less costly to operate than the typical electric storage tank. Moreover, a propane water heater can keep the water hotter for a much longer time than what an electric heater can.
You can keep your room temperature at a comfortable 115 degrees Fahrenheit when you use a propane heater. This is why a propane system is better than electric heat pumps, which typically deliver air temperature that is slightly higher than the average body temperature. You can continue to use a propane gas heater, propane stove, or a gas fireplace during a power outage, too. Hence, you do not have to worry about freezing and starving when electricity is unavailable.
Appliance Magazine found that a gas furnace could typically last up to 20 years, which is longer than the average 14-year lifespan of an electric heat pump. Most of the time, it can be cheaper to repair a propane furnace than its electric counterpart. A high-quality propane boiler can have a 90-percent efficiency and may reduce your energy usage by about one-third of the cost when use a conventional gas boiler. Propane has fewer emissions compared to other petroleum products. In fact, a high-quality propane furnace can typically emit 37 percent fewer greenhouse gases than a fuel oil furnace, and up to 60 percent fewer greenhouse gasses than an electric furnace.
