The hunt for the most efficient heat pump in the world
A new generation of engineers has realized they can push heat pumps to the limit.
“I’m number two on there,” fizzes owner Rob Ritchie, a retired chemistry teacher, referring to the system’s position on HeatPumpMonitor.org, a kind of online leaderboard for heat pumps around the UK and beyond. Since moving to his detached house near Sheffield about 10 years ago, Ritchie has installed loft insulation and solar panels, but the fabric of the building is not necessarily ideal for keeping the place toasty in an efficient way. Ritchie’s heat pump is not quite in pole position at present, but it is noteworthy, emphasizes Blakemore, because once a year’s worth of data has accumulated this September, it could be the first air-source device on the leaderboard to achieve a 365-day seasonal COP, or SCOP, of 5.
