I looked some more at the home pages of E-Cat Australia and come upon the following relating to the domestic system: "E-cat input power equals 7.6 kWh per day which produces 90 kWh of thermal heat per day" (link: http://www.e-cataustralia.com/benefits/ ) so to my mind it looks as if it is constant input to drive the system.
Anyway, the 6:1 factor of heat production is about twice that of the ground-heat exchange pump system that I have, so that is looking good, but it is not of an order of magnitude higher than existing technology.
A further reserve for domestic use is the water temperature. The home pages talk of 100 C, which for a domestic system is too hot - my system is set for 45 - 50 C with the occasional (every 2-3 weeks) 70 C to kill any germs. This rate is good enough for both showers and heating the house (even down to -25 C outside). On the application area I wonder if the use of boiling water would waste energy, and also increase the danger, unless the boiling water is only heating the hot water tank and is not mixed with the water used in the house (loss of efficiency here?).
In the worked example, with the e-cat unit producing only 50% of capacity it is equivalent of over 15 000 kWh input per year. This is twice what I use for a large house in Northern Europe which includes heating for a long winter. To my mind this indicates a huge waste of energy, but it probably reflects the reality of a rich standard of living.
