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.
Gas furnace life. I just got a quote last week to add a heat pump to my current 14 year old AC/gas furnace system. For fun, I had the dealer quote an all new system as well as the heat pump. From what I've gather on this site the average life expectancy of this equipment is around 15 years.I'd like to just get the heat pump and hope the gas furnace would last 15 more years (life of the new heat pump). The gas (propane) furnace is a Carrier (58SXC080) 92% efficiency.'d like to just get the heat pump and hope the gas furnace would last 15 more years (life of the new heat pump).
