As I said before this is a great little heater and you can build it however big you want. It heats air so you don't have to worry about it freezing in the winter. I live in Alberta and on a Sunny day it will heat 5 degrees Celsius are to 30 degrees calculi's air. It is run by a solar panel so whenever the sun is out it turns on and you have to pay no money to keep it going. I encourage you to make one if you have a small space that you want to raise up a few degrees. Hope you enjoy!
