I have cooked a pizza at 425, without preheating, and it was done in 12 minutes.

It goes up to 450 degrees and usually takes 5-10 minutes to get to that temperature.

You can heat a box probably 12" x12" x 48" in size with no problem, giving enough time for the box to get to temp. It will be 212 deg. inside. Be sure to pre soak the wood first of course and steam 1 hr/ inch thickness. As I'm sure you know, the steam only heats the water you put in the wood from soaking to make the wood plastic. Without pre-soaking the wood will just get hot and brittle.

I normally set mine on the highest heat and it takes less than two minutes to heat up.

I never tried that, but I Googled it. One lady said she put two big cans in on high, and it was ready when she checked it two hours later (She didn't check it any sooner). Somebody else said to heat it on low to avoid scorching and that it would be ready in about 45 minutes. I'd heat it on low since dairy doesn't always do well on high heat.

I would have to say about 1-2 minutes with the adjustment setting at max. The instructions suggest heating up at max, then dialing down as needed. Great soldering iron set

The preheat is a manual feature. You cannot set the time it comes on. There is an "auto-off" button that you can set and the heat will turn off after 10 hours. The preheat will warm the bed up fast and will stay on for 30 min then the control goes back to whatever you set it to. There are 20 heat settings to use. We have found this product to work quickly and has been wonderful during Minnesota winters.

I used for cooking on a standard 120V and one burner can get reasonably hot at a time but don't expect to use both simultaneously with high heat- it takes forever to really get things cooking. Fine for reheating for about 3 months. I ignored other reviewers complaints about early failure of one or both burners and wish I hadn't. Better to buy locally somewhere with at least a 3 month return policy so you can get a replacement or your money back. Not a safe bet for an online purchase IMO.

150. The temperature of 150 would seem to go with the "warming" setting when one wants to preheat the oven.

Haven't checked on times, sorry. That burner is HOT, though, would not take long. You need to be careful of aluminum pans with thin bottoms, it will warp them and if you let them boil dry it will burn through, I am told.

I generally only pre-heat a pan for maybe ten seconds, and I do eggs on medium (5 or 6). for soups, etc, I start at 7 or 8 then reduce to 3 or 4

Sorry, I can not answer this question. I would contact a heating specialist.

We heat a 400 gal hot tub from 70 to 100 in about 3 hours. Hope that helps. Unsure of BTUs.

It depends on the heat setting you choose. About an hour on high heat, 4 hours on low heat.
