How many two-port valves are used in a fully pumped S plan heating system?

• 1

• 2

• 3

• 4

What type of valve is used in fully pumped Y/W plans?

• One-port valve

• Two-port valve

• Three-port valve (mid-position/diverting)

Which of the following is an advantage of the C plan two-pipe semi-gravity system?

• All heat emitters reach the same temperature

• It uses only one pipe

• It is not compliant with regulations

• It cannot control hot water

Why might someone choose a two-pipe system over a one-pipe system?

• It is quicker to heat up

• It is slower to heat up

• It uses less water

• It is harder to control

Which of the following is true about boilers fitted to the C plan two-pipe semi-gravity system?

• They tend to be lower efficiency

• They are always high efficiency

• They use solar power only

• They do not need water

If you want full control on heating and hot water, which system should you consider?

• C plan two-pipe semi-gravity

• Single-pipe gravity system

• No heating system

• Solar-only system

Imagine you are designing a heating system for a house. Why would it be important for all heat emitters to reach the same temperature?

• To make sure every room is comfortable

• To save money on paint

• To make the house look nice

• To use less electricity

What type of fuel is used with a two-pipe semi-gravity system with a heat sink?

• Solid fuels

• Gas fuels

• Oil fuels

• Solar power

What happens if gravity circulation stops and the flow and return are the same temperature in a two-pipe semi-gravity system?

• The boiler will stop producing heat

• The boiler will still produce heat

• The system will cool down quickly

• The heat sink will stop working
