Hmmm. Slight inaccuracy? Or maybe someone dropped figures instead of rounding.

Seconds in a year = 31557600

240W for 31557600s would be 7.57GJ 500W for 31557600s would be 15.8GJ

So rather than '7GJ to 15GJ per year' one would think '8GJ to 16GJ per year' would be more accurate.

Or was there some % of downtime for the pilot light? Perhaps.

Not that this is in sigificant error...Since the error in measurement is likely to be bigger then bunged rounding.

I computed them using units. The calculation went the other way (from energy to power). The numbers are probably wrong anyway - 500W would have a noticable warming effect on a hot water heater and would probably cause the water to boil over a day (a kettle is only 5times more power). I rounded to nice looking numbers (the precision is probably less than 1 sig fig).

You have: 73 therm
You want: GJ
       * 7.7000692
You have: 73 therm/year
You want: W
       * 244.00568
