abstract
This paper reviews current heating system control practice in the UK through surveys, computer simulation and experimental studies. It is evident from the survey results that both boiler and heat emitter controls in the UK are generally poor. Computer simulation of a heating system demonstrated that the use of poorly commissioned boiler controls and the use of thermostatic valves with limited flow control leads to buildings not maintaining the desired internal temperatures. This results in occupant discomfort when under-heating occurs and excess fuel consumption when over-heating occurs. Finally, an experimental study demonstrated that a newly developed boiler control algorithm can offer significant energy savings by controlling the boiler more appropriately and reducing the effect of poor thermostatic radiator valve use.
note
[Modelling with EU CRAFT. Study buildings not dwellings. Quote: "The survey also found that 95% of radiators were controlled using TRVs (thermostatic radiator valves). The survey revealed that more than 65% of TRVs were performing very poorly. One of the problems was that they failed to reduce the heating output of radiators when the room temperature was greater than its desired value. As a result, the rooms overheated and energy was wasted. Discussions with building occupants indicated that most of them did not know what the function of the TRVs was or how they should be operated. During the walk-through surveys, 32% of TRVs were found to be set at "MAX" and more than 65% were found to be set higher than required. This suggests one cause of the overheating experienced in many buildings." Quote: "The majority of the heating systems surveyed were not operated efficiently due to incorrect control of both the boilers and heat emitters."]
