Is Solar still cost efficient in Ontario?

[SalemCastles]

I'm also in Ontario and subjected to Time Of Use Rates. I have a 1hp motor which as stated is about 746 watts or .75 kwh. Because they never run at 100% efficiency let just say that your 3/4 hp draws the same as a 1 hp is rated at while I calculate my 1hp at 1kwh or 75% efficient. At peak rates your paying $1.80 a day. Less than you spend at Timmy's for coffee. As far as the gas usage I turned my Rapak 255 gas heater on and went to the gas meter and timed the amount of flow per minute. I came up with about 2.00 /hr to run the heater. I get approximately 1 degrees rise per hour in my pool. I've looked at a few solar heaters and based on the initial investment it has never been worthwhile to purchase or even build one. I can run my heater for hundreds of hours for the same money which I never do. I use the heater to get the temp up at the beginning of the season ..let the solar blanket maintain it through the week and then a bit on the weekend depending on weather and/or occasion eg. pool party, spouse whining etc The fact that you have a solar system already would make me believe that you're way ahead in just running your pump 24 hrs a day.
