Using Oven to Heat Short Bus

[pizzabus]

Hi, I'm converting a short bus into a mobile tiny house and I'm exploring the possibility of installing a 52x52 pizza party oven for not only cooking but for heat too. My question is, how much heat is produced outside of your oven? Do you think it would be enough to keep a 120sqft room warm in the brutal northern winter? I understand the oven itself is quite insulated, but figure there will be plenty of heat coming off the chimney and out of the door.

Thanks!
