thinking about trying to heat pool this weekend. temp should be 70 degrees each day, 55 at night. current pool temp is 55.
Does math below make since/sound right?
Total Gallons = 18500
Wind Speed Average = 3.5 MPH
Desired Temperature Rise = 20 degrees
Heater BTU's = 200000
Heater Efficiency = 80%
Fuel Cost per therm = $.35
Our calculations based on your information shown above are as follows:
Total therms required = 38.53
Time (in hours) to raise 18500 gallons of water 20 degrees = 19.26
Time (in minutes) to raise 18500 gallons of water 20 degrees = 1155.79
Cost to raise 18500 gallons of water 20 degrees in 19.26 hours @ $ .35 per therm = $13.48
