My wife Sandy and I live in rural Hubbard, Iowa. We live in a 32’ by 42’ Morton-style building that is attached to a larger machine shed. The 1,350 ft2 home has 10’ walls and a 14’ cathedral ceiling.
During the epic blizzard of 2007, we lost power in our home for 4 full days. It took until the end of the fourth day (when the power came back on) for the temperature to drop to 52 degrees. We used a 1 lb propane tank (similar to what you would use while camping) to run a very small heater each night, and that actually warmed up the whole house 2 degrees!
Last year, we only used 500 gallons of LP in 12 months to heat our home as well as all of our domestic hot water! We had Icynene sprayed throughout on all wall and roof areas. Our last home, which was 2,600 ft2 took 1500 gallons of LP for the year. Pretty amazing.
Icynene does what it says it will – it pays for itself in one year. I would recommend Icynene to anyone.
