Update on the coolant heater.
It seems like the best increase in temperature that I'll get is 25C above ambient after 1.5-2 hours. Not exactly a RED HOT engine at this time of the year, but enough to have heat in the cabin at least 1km sooner (after 1-2km instead of 3km). It'll also bring the coolant to above freezing even in mid-winter, unless we get -31C again this year.

I've started paying attention to how fast the engine cools off now. The other day it was around 2-3C outside when I parked and about 2 hours later the coolant temperature had fallen to 40C from 80C. Later that evening it was around 1C (plus windy) and the coolant temperature after 2.5h was 24C, from 82C. So I think I'll look into blankets and other ways to keep the heat in. I already have an OEM blanky on the underside of the hood (bonnet), but I bet that it's for noise control as much as holding temperature. Maybe I'll add some foil to that?

What matters is where you're going, not how fast.
