I have been planning to get an Alpha flow-Smart 25 package (combi + gas saver + 25l store) as part of energy efficient refurbishment of my Mum's house.
Seems on the face of it like a clever little system to get decent dhw flow rates and good energy efficiency at the same time. (Have looked at various test and simulation results and, though I am duly cautious of potentially overstated savings, there seems to be some merit at least)
Looking at prices (around £2k - ish for Flow Smart package), I'm wondering how this package compares value-wise with a pressurised system boiler and cylinder set-up.
I can't imagine there's much between the two approaches, in which case I'd err towards the Flow Smart on energy efficiency grounds. Am I missing something major in terms of performance and/or quality?
Thanks
