I’ve read several posts talking about BTU’s for gas ovens. How does that convert to watts for electric? Is a 12,000 watt deck oven that is 36x57 any hotter than a 8,000 watt oven that is 36x42? Someone please explain this to me!
1BTU is .29 Watt Hours
Daddio knows his BTUs & Watts.
Is there a minimum wattage that I should be looking at? I’ve seen lots of posts about recommended btu’s per deck but not watts. And I get confused about different watts for different deck sizes.
Watts per square inch (W/in^2) is simply the wattage of the oven divided by the square inches of baking surface. Watt is a measure of power. Power is what you need to do work. In the case of a pizza oven, the work is creating heat to bake pizza. W/in^2 is a way of normalizing the amount of work a pizza oven can do relative to it’s size. Say I have two pizza ovens and both are 1000W. If one is 12" wide and the other is 36" wide, you can easily imagine that the smaller oven will probably get a lot hotter or stay hotter during use. Both have the same amount of power but the smaller concentrates the power into a much smaller space. This is why looking at W/in^2 is at least somewhat meaningful and looking at W alone may not be.
BTU in gas is just equivalent of Wattage in electricity. 1 watt (W) of power = 3.41 BTU’s per hour (Btu/h) in power
some calculations I did while choosing my first pizza oven :). However finally went for PizzaMaster PM-722
