Uncooked rice often contains the bacteria Bacillus cereus. These bacteria can form protective spores that survive the cooking process and if the rice is cooled slowly (and left between 5 Â°C and 60 Â°C for a long time), these bacteria spores can germinate, grow and produce a toxin (poison) that causes vomiting.
Obviously the colder a climate is, the more a furnace is required to run, and the shorter its life expectancy. With our relatively mild climate here in Seattle and the rest of the Puget Sound, the average life expectancy for a gas furnace is 15 to 20 years if well maintained, properly installed, and properly sized.
Another pro of the electric system is that these systems are quiet and usually more durable than gas units. The lifespan of an electric furnace is between 20 and 30 years. The installation process is generally faster than with a gas unit.atural gas is a cheaper form of energy than electricity and over the past few years, the cost of natural gas has actually decreased. However, a gas-powered unit will require a larger initial investment than an electric unit. Gas heating systems generally heat the home faster than electric units.
