What type of valve layout is associated with a fully pumped system that uses an S plan?

• 1 x three-port valve

• 2 x two-port valves

• 3 x two-port valves

• 3 x three-port valves

Which plan is associated with a fully pumped system that includes 3 x two-port valves?

• Y plan

• W plan

• S plan

• S plan+

What type of valve is used in a fully pumped system that follows the Y/W plans?

• Two-port valve

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

• Four-port valve

• Five-port valve

What is the C plan+ in the context of the Regulations?

• A) A system that does not comply with building regulations.

• B) The maximum acceptable compliant system with building regulations.

• C) The minimum acceptable compliant system with building regulations part L1B.

• D) A system that requires no thermostat or zone controls.

According to the Domestic Heating Compliance Guide, what does the C plan+ system need to incorporate?

• A) A fully pumped system.

• B) A thermomechanical thermostat.

• C) A digital thermostat.

• D) A zone control on the cold water.

What does the current compliance guide suggest as best practice for updating the system?

• A) Maintaining the system as a two-pipe semi-gravity system.

• B) Incorporating a digital room thermostat.

• C) Updating the system to a 'fully pumped system'.

• D) Removing all zone controls from the system.

What is the diameter of the gravity primaries in the C plan two-pipe semi-gravity system?

• 15mm

• 22mm

• 28mm

• 35mm

What component controls the flow of water to the cylinder in the C plan two-pipe semi-gravity system?

• Boiler

• Pump

• Motorised valve

• Programmer

What is one of the advantages of a C plan two-pipe semi-gravity system?

• It requires more time to heat up.

• It offers no control over heating and hot water.

• All heat emitters reach the same temperature.

• It is not compliant with building regulations.

Which of the following is a disadvantage of a C plan two-pipe semi-gravity system?

• It provides full control on heating and hot water.

• It is compliant with building regulations L1B.

• Boilers fitted to this system tend to be lower efficiency.

• It uses a single-pipe system.
