Anyway to figure out cost per hr of a natural gas heater?

Have to verify the 333K is total or output, that is whether efficiency has to be figured in the calculation. Not sure of this but it may be that gas companies may charge per cubic foot in which case you have to figure in the cubic foot to therm factor which is very close but not quite 1.00

That number is the amount of fuel consumed per hour, it has nothing to do with efficiency. The actual heat put into the pool will be less than that based on efficiency of the burner and heat transfer - but that is still the amount of fuel you are consuming.

OK, here's what and how I measured. I don't really care about how much my pool heats up, just how much it costs me to run it per hour. It's heats it up really fast anyway.
My bill is in cubic meters, no therms on it anywhere. I turned the heater on and timed the meter and this is what I got.

.05/m3 used every 20 seconds
20 seconds x 3 = .15/m3 every minute.
.15m3 x 60 = 9 m3/hr

With transport charges, storage, delivery I pay 45 cents/M3 of natural gas so....

9x.45= $4.05/hr to run the heater.

Seems low (good for me) but maybe I calculated wrong. I am not a mathemetician by any stretch of the imagination.

Thoughts? If it's correct at least others may be able to compare what a heater costs to run.
