A test of the 413D

Here we go--Type A-Ness to The Max!
We fired up the new 413D and amazingly got the right burner to 977 degrees!  It actually maxed out the temp gun a couple of times.  That means it went over 1000!

Meanwhile, we put on precisely one gallon of water.  We want to cook four ears of sweet corn.  A gallon can cook more than four ears but we figured bringing a gallon of water to boil would be a good test of the 413D.  We actually used a measuring cup to make sure we put in precisely 128 ounces of water.

The pot is 10 inches in diameter and 8 inches tall.  The water content is 3.5 inches.  The water temp was 68 degrees before we put it on the stove.  The ambient air temp is 85.  Winds are light, officially 6 mph right now at the Idaho Falls Airport.  We put the water on at 6:12:30.  We will now go out and monitor the water and see how long it takes to boil a full gallon.

Most stove testers use the Boil Time  (BT) for a mere CUP of water!  What good is that unless you are a backpacker making soup?  Why not go the full monty.  A gallon BT will really tell you something.
The only other BT that matters is a coffee pot but the size of those vary so widely it's hard to find "commonality."

The water came to a roiling boil at 6:37:00, that's 30 seconds less than 25 minutes.  Yes, that seems like a long time but for a FULL gallon of water, that's nothing.  We put on our four ears of corn at 6:38:00 and will time how long it takes to bring it back to a boil.

WOW, It came back to a boil in less than 3 minutes!

We pulled the corn off after 6 minutes BT @ 6:44 pm.  We let them cool for a couple of minutes and scarfed down those ears like we were starving sailors stranded on a desert island.

As long as the stove is already set up, I think I will test boil a pot of coffee.  Stay tuned.

I put the pot on at 7:04:00 and it boiled at 7:16:00.  Bear in mind it's a large pot with a small bottom surface area.  Stainless steel pots with large bottom surface areas will have lower BTs than smaller diameter vessels.
This particular coffee pot is a Family Heirloom.  It was the pot Doris and Don used on all their camping trips.  It was in their camper th day Don had his unfortunate accident up in Washington!  As such, we consider it a Sacred Obligation to use this pot to make our coffee for as long as this pot shall last.

Sometimes I get impatient with the pot and boil water in a larger diameter stock pot and then pour it into the coffee pot.  This is a valid option for shortening the BT of coffee water.  BT is what it is all about in camp.

Well, that concludes our test of the 413D.  I will add photos later.  At least we have the data.  Cheers, jp

No, not quite--the Doris & Don Pot holds a couple of ounces over 8 full cups--that's 64 ounces!  That's a half gallon.  So the BT was actually pretty good.  A full gallon with a much larger diameter bottom took 25 minutes.  A half gallon with a small bottom took 12 minutes.  All-in-all, I'd give that an A+.

What we do in camp is real simple.  We get up and put on coffee water and then do all the other camp chores one does in the morning.  It usually takes awhile to get a fire up and running.  It take awhile to go to the outhouse and so forth.  So, the 15 minutes or so that it takes to boil the coffee water doesn't really seem so long.  Bottom line is that we let out coffee percolate for 10 minutes so you know it's at least 25 minutes to coffee when you get out of the tent.  It simply cain't be done quicker for the coffee quantity and quality we desire.

  1. You know, a month ago when we were up at Dead Horse I'd say it took a good 30 minutes to boil the kettle of water...this is on that new stove i was talking about. I don't think the altitude would have added that's only about 4000ft if I remember correctly, and it certainly wasn't a full gallon of water. Leads me to think your theory on the old coleman's burning hotter is right!
