[Healeys] Heater query

[simon.lachlan at alexarevel.plus.com]

I have a MkII BT7 with a normal Smith's heater. Normal insofar as it never
seems to be turned OFF 100% or ON 100%.

We are in our summer(?!) at the moment and I was wondering about turning off
the tap in the hose from the block that leads into the cabin for the heater.

Would the heater box and/or its valve semi-dry out and fill with a mess of
rusty crud?

Would the engine run hotter as there was a little less water running through
the system?

Or would I find myself basking in cool luxury as I tootle off to the local
boozer?

Or, most likely, none of the above, especially the last one?!

I did take the car on quite a long trip the other day (Le Mans Classic!!)
and, once the heat had soaked through the insulation, we were quite warm..

The more I think about this, the less I like the idea of turning that tap
off...

The tap does work, before you all shout at once!
