I use a heat mat in my Fv fridge controlled by an ATC 800+.
I have also tried a belt and also a 60w tube heater.
The mat is for me, by far the best.
As you are only heating up to something like 20c,
once it stabilizes the mat is hardly on.
As far as im aware there are no off flavors caused by using a heat mat.
I've never Baked the yeast cake.
Norm.
p.s. Your gettin' a bit tecky mate arnt you. youll be using an airlock next.
