We have a small inground and indoor pool but are uncertain on the most cost effective method for heating it during the winter. The room has great ventilation for humidity and also has both an elec. room a/c & heater as well as a propane gas stove and ceiling fan. We have placed a solar blanket over the pool when we are not swimming and the water has both a solar and a propane gas heater. The solar must be turned off just before the first freeze here in central NC. So the real question is what's the best pratice for gas heating heating the pool during cold months?
IF we want to swim in 85 degree water in Nov - Apr, do you think it would be cost effective to turn the heater down to say 75 at night and then raise it to 85 degrees during the morning to swim in late afternoons/night OR would it be better to keep the pool heater & pump running at 85 degrees 24 hours a day? I have no idea yet on the cost for operating the pool during the winter as this is a new pool and the first day we have used the heater. It may just be the only month we do so if we find it far too high a cost. Any insight from your knowledge and experience would be sincerely appreciated.
