What is the minimum acceptable compliant system with building regulations part L1B and the Domestic Heating Compliance Guide?

• Fully pumped system

• C plan+

• A plan semi gravity system

• 2 Pipe semi gravity with heat sink

What is the disadvantage of a C plan+ system?

• Reduced efficiency

• Overheating possible

• Restricted heat control

• Not fully pumped

What is the advantage of a 2 Pipe semi gravity with heat sink system?

• Can be expensive

• Compliant with building regulations (Part L)

• Restricted heat control

• Overheating possible

What sort for system is this?

• Open vented s plan

• Sealed system Y plan

• Sealed system s plan

• Open vented Y plan

What is the purpose of a heat sink in a 2 Pipe semi gravity system?

• To dissipate excess heat from the boiler

• To increase the efficiency of the system

• To control the heat output of the boiler

• To regulate the flow and return temperatures

What type of systems are suitable for using a heat sink?

• Closed vented systems

• Fully pumped systems

• Open vented systems

• Gravity circulation systems

What is the advantage of using a pump in a heating system?

• Lower efficiency

• Restricted heat control

• Higher operating costs

• Quicker heat-up times

What is the purpose of a cylinder thermostat in a modern heating system?

• To increase the efficiency of the system

• To monitor the temperature of the hot water cylinder

• To regulate the flow and return temperatures

• To control the heat output of the boiler

What type of fuel can be used in boilers for modern heating systems?

• Solid fuels

• Natural gas, LPG or oil

• Electricity

• Coal

What sort of system is this?

• Semi gravity with a heat sink.

• Fully pumped with a heat sink.

• C plan with a heat sink

• Y plan with a heat sink
