Dave Elliott: Following a new review by the Energy Saving Trust, ten years on from its landmark report into the quality of heat pump installations in the UK, the EST now says ‘it’s time to reset your opinions on heat pumps -particularly air-source heat-pumps’. As it admits, there had been some serious criticism of heat pump performance, air source systems in particular, which seemed not to be well suited to often cold, damp UK. However, improved technology and better installation evidently means that all is now well in most cases, with EST/ICAX noting that most users were happy with them. Indeed, in a Blog (that sadly now seems to have been blocked for some reason), EST’s Ben Whittle was so enthused he said that we didn’t need to go for hybrid heat pump/gas heating system as proposed for home heating by the government and the Committee on Climate Change (CCC): ‘An all-electric heat pump has an auxiliary electric heater to assist in the coldest months – the vast majority of heat pumps available in the UK have this feature built in. So why would we carry on leaving a gas connection in place and maintaining two pieces of equipment when for the very large majority of houses, an all-electric heat pump will do the job?’ He went on ‘When we look at running costs, we are weighing up the very small number of days in the year where a heat pump might require assistance from an auxiliary source, versus the cost of maintaining the back-up heat source. Again, it will vary depending on where you are in the UK but many people won’t require much back-up heating at all’.
