Nonsense you can easily raise the temperature of the water to a higher level than the outside air.
Water temperature off of solar roof.
Solar powered water heaters are an extremely effective way to maintain a constant supply of hot water in the house.
Keep in mind that lower temperature settings are more energy efficient.
These heaters work by feeding off energy from the sun which is collected in panels that are position on the roof or exterior wall of a property.
Solar powered heaters are durable and reliable.
One temperature sensor is on the roof positioned where it will get sun whenever the collectors are getting sun and be shaded whenever the collectors are shaded.
The water temperature must never be cold putting cold water into a hot panel can crack the glass and damage it badly.
The other temperature sensor monitors the temperature of the pool water by being inserted into a pipe that contains water coming from the pool.

The ability of the material to reflect the sun s energy back into the atmosphere called solar reflectance and the amount of heat the material rejects instead of absorbs called thermal emittance both are measured on a scale from 0 to 1 with higher scores translating into cooler roofs.
It activates while the solar tank is gaining temperature.
The rooftop temperature results from two different properties.
Turn the temperature knob 3 clockwise to increase the water temperature.
The theory here is that if it s only 75 degrees outside you can only get the pool up to 75 degrees using a solar pool heater.
Use a screwdriver to adjust the thermostat dial until the minimum acceptable temperature is reached.
Recommended water temperature is around 25 30 c.
The thermostat is factory preset to 120 f 49 c.
Using sensors to measure roof temperature and moisture these systems can lower rooftop temperatures by as much as 40 to 60 degrees fahrenheit 4 4 to 15 5 degrees celsius on a hot summer day while consuming less than one pint 473 mililiters of water per square foot per day source.
