About 5 years ago I installed solar heating to our pool which is barely OK for us in mid-summer when the heat is intense in South West Ontario Canada but, in spring and fall when it's not as hot & the days are shorter it doesn't cut it. The highest we get is in the 82F range in summer so not that great.We have quite a bit of shade & I have a solar blanket on always but the kicker here in Ontario is that our power is the most expensive and we are on time-of-use pricing so in summer the time you want to run through the panels is at the most expensive time of the day at 18c/kwh. During off peak/mid peak we are at 8.7/13.2c/kwh. But our natural gas is reasonable. Would it be cheaper and make the pool more comfortable with a natural gas heater. We have an 18x36 kidney shape with an 8' deep end and a 3' shallow end. If so what size heater would we need? It would be nice to get a full season out of our pool for a change as it is so short to start with.
Thanks in advance.
