Will it make my system more efficient if I set the cylinder temp higher than usual (say 70) and use a TMV for HW distribution; then set the boiler so that it doesnt fire for HW until the cylinder drops to 40?
The cylinder has 50mm insulation, and I've read somewhere(!) that modern boilers work best when they are working hard.
Planning a new install, so would be using a new boiler and a cylinder with a 'high recovery' coil.
