A somewhat related question: I am in Peco's Philly area, with electric
rates near 12c/kwh, I believe. However I have and use the Rate timed
rate for all evening uses. I pay double during peak for all uses.
It is almost better as a disincentive to use elec than any real
savings, in my opinion.
My question is Can someone help me figure out how much it costs to
heat up the (cringe) spa from 70 degrees F to 95' ? This would of
course be only at the off peak rate. Just take it as 500 gals x 2.2
pounds per gal. 1100 lbs.

Part 2 would be what does it cost to run the 11.5 hp pump system. It
usually gets run 1 hour, sometimes only 1x/ week. The heatup is only
needed in the real winter months, otherwise it holds the heat very
well. I hope to an an enclosure to reduce this loss. We don't use it
often.
I'll do the math If I can find the formulas or factors. Thanks MG

Where do you get light water? Our's weighs one hell of a lot more than
that.

Holy Crap, an 11.5 HP motor needs a huge electrical supply. Most are three
phase at that power.

Based on your figures above, you can't do the math. Start over with the
right numbers.
