Yes it is counterintuitive. Just went through this. Cable out, heat is off on our 998 engine. Couldn’t find actual operation directions so ordered owners manual. I did notice our host sells a replacement cable with “push for heat” engraved on knob.

I'm not sure about the valve on your 998 but "logic" suggests that in Britain one would normally leave the valve in the "on" position, i.e. knob pushed in, due to the relatively cool, damp climate. If one did not want heat or windshield defogging, they could simply close the eater door all the way. Except for the earliest cars, fresh air ventilation was provided through the eyeball vents. In more extreme climates, one could shut off the coolant flow. Conversely, in Canada Minis were provided with a bigger snail type heater fan in the engine bay. (From experience, I know that was not always sufficient when the mercury dropped in winter.)

Question regarding heat valve off of block.  In process of replacing a 998 with a 1275.  I put on a new heater valve and the way it works seems opposite of what it should be.  Pull the heat knob/cable and it pulls the lever towards the rear of the car shutting the valve.  Push it in and it opens the valve.  It would seem to me that opening it would allow the warm water to circulate through the heater box therefore providing heat to the cabin.  The old one in the 998 works the same way and does provide heat, such as it is, when knob pulled out.  What simple little thing am I missing here???
