Re: Stove Fuel Physics

What we need to do the comparative tests is a "STANDARD POT."

Then we can all go out and buy them and test and share water temperature compensated data.

Our tea kettle is 6 1/2" diameter and appears to have a copperish bottom, blackened. Looks a lot like Panopes pot.

Re: Stove Fuel Physics

I have one of those, Adriatic model, in my hunting cabin.

I hear they work great on work boats.

Takes about a half hour to get water hot enough for tea, provided the stove has run for a few hours to warm up.

I leave the kettle on all the time, just on a bit of sandstone in the corner so it doesn't boil out.

It's the ultimate slow cooker. I put on a pot of beans in the morning and they are good for dinner.

It's a real good cabin heater.

Nope, we need the best pots for every stove. Induction cook top requires it's own and it doesn't work equally well on a gas cooker.

Cast iron pots work about equal on all types of stove

Used to have an attachment for backpacking cookware that wrapped around the pot. It was corrugated metal that extended below the pot and channeled otherwise mostly wasted heat up the sides of the pot. Made a noticeable difference.

Re: Stove Fuel Physics

Kelly Kettle is another interesting device. Designed for camping, but could be adapted to a burner.

Since you raise the point:

They should all by expressed as BTU/hr, including your gasoline and propane stoves.
Stu, you are completely correct in noting the correct use of the term.

That said, I have been an HVAC engineer for the past 45 years and commonly BTU/hour (BTU PER hour) is commonly used as a shorthand as BTUh.

Re: Stove Fuel Physics

Makes me wonder if you couldn't make a super kettle with heat exchanger tubes through it, and space on the top for simmering a pot to catch all the most of the waste heat.

The Thermette comes with removable "cooking ring" so that you can put a pot or pan on top and cook with the waste heat.

I was thinking something like this but much mote squat, like a pot but with several tubes through the middle and a little spout and filler. Another pot could stack on top. I thought the thermette was designed for cooking with twigs burning inside it?

I use cast iron skillets, dutch oven, griddles, heck I even have a cast iron wok. The tea pot sits on my heating stove all winter. What's the problem with cast iron.

As do I for most cooking, but it's not a choice to boil water or for a soup IMHO
becouse you got grease it before and after use.
