热泵是英国家庭供暖脱碳的重要技术。本文报告了一组地源热泵的使用性能，并与其他英国的研究发现，季节性性能不如欧洲大陆的试验报告，系统控制是不令人满意的。控制改进的研究通过一个模型的住宅和热泵作为一个组合系统，从该建筑物的热时间常数被确定为一个关键因素，需要考虑在改造项目，包括热泵。允许热泵连续运行的传统做法（以及安装人员对用户的建议）的有效性受到了测试和限制。改善控制技术的概述和原因，在英国的性能较差检查的结论，热泵需要更好地匹配的容量和控制的大小和热特性的英国住宅。热泵制造商和安装商实施这些发现可以促进英国和国际上类似住房存量和气候存在的地方更快地过渡到可再生能源。
Heat pumps are an essential technology for decarbonisation of domestic heating in the UK. This paper reports on the performance in use of a group of ground-source heat pumps, and in common with other UK studies finds that the seasonal performance is not as good as that reported in trials from continental Europe and that the system controls are unsatisfactory. Control improvements are investigated via a model of the dwelling and heat pump as a combined system, from which the thermal time constant of the building is identified as a critical factor that needs to be considered in retrofit projects incorporating heat pumps. The validity of the conventional practice (and advice from installers to users) of allowing heat pumps to run continuously is tested and bounded. Techniques for improving control are outlined and reasons for the poorer performance in the UK examined with the conclusion that heat pumps need to be better matched in capacity and control to the size and thermal characteristics of UK dwellings. Implementation of these findings by heat pump manufacturers and installers could promote a more rapid transition to renewable heat both in the UK and internationally wherever similar housing stocks and climates exist.
