Hi knowbodies - I've never seen more than about 130 F above ambient using my 800 watt heater (almost identical to yours, bbjsw10).

from: Experiment: how long should a block heater be plugged in? -

That's still well below normal operating temperature.

I guess it's still possible to crack the windshield if it's super cold outside (like -35 C / -31F) ... oh look, you live in Moose Jaw!

Has anyone combined different style heaters on one car? Didn't you do something on this, Darin?
I have an external element style 300w OEM block heater + this convection tank style 800w one. I rarely use them both at the same time, unless I'm in a "hurry" and don't want to wait for the 800w one.
