I am on the board of a small HOA with a heated community pool that is 38ft long by 18ft wide. The cost to heat this pool using a natural gas heater has become very expensive and I'd be interested to know what are some economical and cost effective methods of reducing heat loss or increasing the temperature of the pool? I'm aware of solar pool blankets/covers, however our HOA doesn't have a staff or person that can remove and put back into the place the cover on a daily basis. I'm not a believer in liquid solar pool covers, since I think they are high priced snake oil. One method that comes to mind would be to heat the pool only on request/demand and for a daily fee to cover heating costs, however I'm sure that would be met with resistance by homeowners. I'd appreciate any creative ideas on how pool heating costs can be reduced.
