Martin PughAnother fantastic article written by @zarch1972 of @energystatsuk fame discussing how he manages his Mixergy hot water cylinder with his heat pump. As always, tons of real world stats that help tell the story and I'd never considered the possibility of it being more efficient to heat water a bit hotter than you need and to then mix it back down to help stretch your water capacity with a smaller tank.
