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.
Dislikes (Received). 0. This is Turtle. i would expect a longer life span out of the 90% afue furnace for the better quality of the equipment put on it. Lord i need to move where you are for here the life spand of furnaces is about 20 to 30 years in Louisiana. i have turned my gas furnce on 8 or 10 days this year.
