I want to know the answer to the following question:
What type of solar water heater is used to heat pools?
All the background I'm provided with is that "The most common types of solar water heaters are evacuated tube collectors (44%) and glazed flat plate collectors (34%) generally used for domestic hot water; and unglazed plastic collectors (21%) used mainly to heat swimming pools.". Is that enough to answer the question?
Answer: yes
