Hi James
Yes you have been well and truly bitten by the bug. :cheese:
First thing you can do is improve your insulation. This will markedly decrease your heating bills and increase efficiency. It could be the difference to preheating for over an hour to preheating for 30 minutes or less.
Other students have told us about the heaters they have used. You can find that discussion here: Home Heaters.
You have high ceilings so you know what that means to heat. You may need to investigate infrared heaters. In my home studio I have some heaters that are positioned facing downward and then I also have a heater near the floor. So the convection set up in my studio is efficient.
How high is your ceiling? Just curious. It may actually help others who want to give advice!
Namaste
