- Q1Out of the following locations, where would the air vents be located on a central heating system?Just prior to each zone valveImmediately above the circulatorOn the cold feed to the air separatorAt the top of every radiator30s
- Q2Identify one advantage of underfloor heatingDoes not need to be fully pumpedCheap and easy to installEven spread of heat in each roomNo requirement for balancing the system30s
- Q3One advantage of installing a fully pumped central heating system isIt controls the heat recovery time economicallyIt is cheap to installIt allows each room to be heated to a regulated temperatureThere is no danger of overheating30s

- Q13What is meant by the term Delta T?The difference between the water temperature in the boiler and the radiatorsAn elite squad of trained soldiersThe difference between the ambient temperature in the room and the ambient temperature outsideThe difference between the water temperature in the radiator and the ambient temperature in the room30s
- Q14What is a disadvantage of underfloor heating?Increased costsAll of the aboveTakes longer to heat room due to lower working temperaturesCan cause "sweating" of furniture30s
- Q15When commissioning a system for the first time what should be done prior to water tightness testing?Clean all flux from the pipeworkEnsure all radiator valves and TRVs are openEnsure the boiler has a gas supplyEnsure the flux you use is non-active30s
