solar heating-check my thinking please.

[tenax]

I used the calculations program..it was very revealing!

heater with no solar cover, no solar heating panels-heating cost (based on an 83 degree optimum pool swimming temp and variables for my area of calgary) 2243 dollars for the 5 month swim season for ngas.

heater with solar cover on anytime not swimming, no solar panels- the heating cost for the season drops dramatically to 1036 per season.

heater with solar cover and a 8 ft x 20 ft solar panel array- the cost drops to 729 per season.

clearly, the value of a 100 dollar solar cover is huge..the solar array will pay for itself at a 1,000 to install myself in 3 seasons.

it was an easy convincer for my wife of my next project this spring
