Solar Thermal Hot Water Systems P3L3U10,LO1.1P1,5.16

What is the main benefit of using solar thermal hot water systems?

• Increases carbon footprint

• Reduces energy costs

• Works only in summer months

• Requires frequent boosting

Where are the solar collectors typically installed for maximum solar heat collection?

• North facing roof

• South facing roof

• West facing roof

• East facing roof

Which type of solar collector is ideal for use in colder climates and wintry weather?

• Direct Flow Evacuated Tubes

• Flat Plate Collectors

• Heat Pipe Evacuated Tubes

• None of the above

What is the purpose of the copper or aluminium fin inside the smaller tube of the solar collector?

• To remove air from the space between the tubes

• To transfer heat to the fluid inside the pipe

• To connect to the manifold

• To create a vacuum

What is the temperature that the inner glass tube of the solar collector may reach?

• 150°C

• 100°C

• 50°C

• 200°C

What is the purpose of the special coating on the absorber plate of the solar collector?

• To connect to the manifold

• To transfer heat to the fluid inside the pipe

• To allow very efficient heat transfer

• To create a vacuum

What is the function of the manifold in a solar collector?

• To distribute the solar heat evenly

• To absorb solar heat

• To connect the tubes and carry the heated fluid away

• To create a vacuum

What is the role of insulation in a solar collector?

• To increase the temperature of the fluid

• To prevent heat loss

• To create a vacuum

• To connect to the manifold

What is the advantage of using evacuated tubes in solar collectors?

• They require less maintenance

• They are more efficient in cloudy weather

• They are cheaper

• They work only in summer months
