For safety reasons, I do not want to use a solar blanket or solar pool cover. What can I add to the pool to increase the heating efficiency of the solar pool heater?
There are plenty of liquid chemicals that can be added as a type of liquid solar blanket. It is not known to be as efficient at keeping the heat, but it can help to supliment the solar pool heat.
Could you name the chemicals, please? Could you explain how they work?
If you search for liquid solar blankets you are sure to find a number of brands. They all work bay the same basic method of providing a thin layer of non-hazardous chemical that floats on top of the water and provides protection from heat loss and prevents evaporation. The chemical degrades over time and either needs to be continually dosed or slowly doses through the floating dispenser.
