Underfloor Systems Quiz

What is the main advantage of using zoning in heating systems?

• Increases energy usage

• Reduces energy usage and costs

• Requires more thermostats

• Complicates the heating system

Which of the following is a benefit of underfloor heating systems?

• High temperature operation

• Visible heat sources

What is the purpose of thermostatic radiator valves (TRVs) in a heating system?

• Increase heat output constantly

• Vary heat output of emitters

• Reduce the number of zones

• Eliminate the need for programmers

What percentage of heat is radiated from the hot surface of radiators in traditional wet central heating systems?

• 10%

• 20%

• 30%

• 40%

What is the main method of heat emission in underfloor heating systems?

What is the purpose of using a thermostatic blending valve in an underfloor heating system?

• To increase the water pressure

• To blend the flow water with return water

• To reduce the noise of the system

• To filter impurities from the water

Why is zoning with 2-port motorised zone valves beneficial in heating systems?

• It reduces the cost of installation

• It allows for independent time control of heat emitters

• It increases the water temperature

• It simplifies the plumbing layout
