Does Heliocol work when it is cloudy outside?
As long as it is daytime, the Heliocol system absorbs solar radiation. Any solar radiation absorbed by the Heliocol system is then transferred into the pool water. Therefore, even in cloudy conditions, the Heliocol system will heat your pool. It is important to note that increasing the number of solar panels in your system will help absorb more heat. As with any heater, using a pool blanket is advisable, as it will reduce heat loss.
