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.
WHAT IT IS. A gas furnace is the heating component in a majority of systems in colder weather climates. It converts gas to heat. Another option is an oil furnace that uses oil as its fuel instead of natural gas.The main components to a furnace include burners and heat exchanger, blower and controls.Trane gas and oil furnaces are built to perform again and again, year after year. Beyond performance, we also provide options for energy-efficient operation.he main components to a furnace include burners and heat exchanger, blower and controls.
