Kilojouls to BTU

Scott Hansen asked Andrea Rossi recently about the energy output of the domestic E-Cat. Hansen lives in Fairbanks, Alaska. The average high in Fairbanks during the winter months is 3 degrees F, with an average low of -11 degrees F. However, a record low was recorded in 1961 at -66 degrees F. Living and working environments in this part of the continent are among some of the markets that stand to benefit the most from E-Cat technology, especially now that the units can be powered by gas and/or electricity.

Hansen asked the BTU provided by a home unit. Rossi said that “the home  unit will yield about 40,000 kJ/h. One kilojoule, or kJ, is equal to almost 1 BTU – .9478 BTU, to be exact.

Therefore, 40,000 kJ would produce 37,912.68 BTU.

In calculating the power necessary to heat and cool an 1800 square foot house, much of the variable will depend on the construction of the home. Insulation, construction materials, and energy efficiency will make a big difference in the energy necessary to regulate the environment. Windows, alone, often account for 80% of energy loss in most houses.

However, assuming that you have a well-insulated house, with fairly energy-efficient windows, it takes, according to some figures, about 100,000 BTUs to heat or cool an 1800 sq. ft. house. This means that you would require at least 2 E-Cats, if not 3, for an 1800 sq. ft. house.

A new air conditioning unit of the appropriate size costs $3000 USD, and a home heating unit of that size costs the same. At estimated much lower costs than that, E-Cats will still be a major cost savings at the point of purchase.

The fact that the E-Cat can now be started and maintained with gas will make it even more economical in operation and it would be the more efficient and affordable option for home heating and cooling.
