Efficiency Killer? Are Buffer Tanks Costing You More Than You Think?

Are buffer tanks doing more harm than good in heat pump systems? In this episode, we explore whether they are a necessary component or an outdated design choice that reduces efficiency. Our expert panel includes: Leah Robson (Your Energy Your Way), Mario Dodic (Heat Pump Consultant, Trainer & Engineer), Brendon Uys (British Gas Net Zero) and Neil Sawers (Grant).
