What is the purpose of glycol in the heat transfer fluid?

• To increase the temperature

• To prevent freezing in colder temperatures

• To enhance solar absorption

• To reduce system pressure

What is the primary function of a hot water storage cylinder?

• To cool down the stored water

• To transfer heat from the system fluid into the stored water

• To store cold water for later use

• To generate electricity
