More stuff. The pump on the 4 year old mid efficiency boiler is an Armstrong pump which draws 3.3A. I'm getting rid of the red beast and putting in the Taco Bumblebee which uses around 20w. A no brainer for sure and I will reuse it when I change to the high efficiency boiler.

Little room off the main house had no insulation in the walls, all single glazed windows and a HUGE fin tube radiator which may not have even kept up with the heat loss. New windows, spray foam everywhere and a new Stelrad (much more efficient).
