Hi all,
I'm trying to figure what my electrical cost is to run my pool. I run my 1.5 HP pump for 12 hours. I also run my SWG at nominal 40% for the full 12 hours.
So that should be 946 Watts per hour x 1.5 HP x 12 hours x $0.12 per KW-hr.
My math equates that to $2.04 per day to run the pump.
For the SWG, I am running approx 20 volts and 5amps, which makes for nice simple math of 100 Watts, running for 4.8 hours per day. I do realize my SWG will increase the purity % as the water temp increases, but for the sake of this discussion we'll just leave it at a flat 40%.
So that's 0.48 KW-hrs per day, which is like $0.06 per day, which is a rediculously low number, but the math is what it is. (Unless I'm doing something wrong?).
The controller also runs for the 12 hours, but it's not doing anything other than powering the LCD and cycling the cell on/off every 15 minutes or so depending on the %.
If there's a fault, then a big bright red LED turns on, but that can't possibly use much power. Literally a fraction of pennies.
So everybody, how's my math and my logic?
Thanks in advance
