I would investigate a smaller heater than your 750 watt one. If something malfunctions you might do some serious damage to the inside of your refrigerator with that much heat if it doesn't shut off. My small heater will only cook the beer and yeast at worst, not melt the inside of the lid.
thanks by the way, I wrote a reply to this (long winded drinking to much) and then when I clicked post I was not logged in! doh!
anyway what info you gave me was great./ it will work and hold the temp fine.
also I started looking into low watt heaters and see a few.
do you use a ceramic heat bulb type?
I thought the one I had was ok because it has a low and high. it runs 750w on high and I just keep it on low which is like no heat compared to high. lol
it is nice that it has a fan as well.
