Pool water temperatures can drop substantially after a few days of cloudy weather which can deter the toughest of kids. 90% of swimming pools that are not heated are only used for 3 months of the year, from December - February! In this article, I am going to provide my professional opinion as to why I think a Heat Pump is better than Solar Pool Heating!
The main and only reason to heat your pool is to enjoy it all (nearly) year round. Old school heating methods (Electric kettle style) were very expensive and ineffective, fast forward to 2020 and Heat pumps are by far the most economical options to heat nearly any pool. With even further technology advances you could connect a heat pump to a solar electricity installation on your roof to virtually cost you $0! So while the sun is shining on your roof, your pool is powered and heated all day long.
Solar pool heating comes in a close second to heat pumps, While relatively expensive to install, over the life of the system it can be cost effective. Solar systems use strips or panels of collector tubes, which are mounted on your roof, with your pool water pumped through it continually (as a slow rate). It can still heat your pool water if it is cloudy, though not to usual desired temperatures as full sun would. If there's consecutive cloudy days, your temps will plummet. It is important to note that an additional “Solar Pool Pump” is also required to operate the solar heating system, this is an additional electricity cost.
