In spite of the hype that causes Paul and Drivel to both be taken in. I like the unit but they should be selling it as an add on the a NON-condensing boiler to convert it to a condensing unit in DHW.
The i/c water at 10°C can extract a lot of heat from the flue gases at 40-50°C and it would perhaps extract an extra 10-15% efficiency from the flue gases of a non-condensing boiler in DHW model.
