10 Questions
What is the purpose of a parabolic mirror in some solar water heating systems?
To concentrate sunlight on the tube
How does the 'drain-back' concept work in solar water heating systems?
All the piping is sloped to cause water to drain back to the tank
What are the two types of solar collectors mentioned in the text for collecting heat for domestic hot water?
Flat plate and evacuated tube
In what way do evacuated tube solar collectors perform better than flat plate collectors in cold climates?
They only rely on the light they receive and not the outside temperature
When are flat-plate collectors generally a more cost-effective solution than evacuated tubes?
In extremely hot climates
What is the purpose of solar water heating?
To heat water using the heat from the Sun and reduce the need for gas or electricity.
How does natural convection aid in the flow of hot water in solar water heating systems?
Convection helps the flow of hot water out of the top.
What causes the buoyancy force in solar water heating systems?
The difference in densities during heating.
Where is the collector for solar water heating typically installed?
On the roof of a building, or on a wall facing the sun.
What is the working fluid in solar water heating systems?
Water
