After some recent parts replacement with my 414 powerhouse coleman dual fuel stove, all is working good.

However I decided to see how long a billy (std 1ltr job) took to boil on the main burner at full tilt.

I had the lid off so I could see and it took 7 mins 30secs.

Has anyone else compared this, that was on coleman fuel.

Any different on unleaded?

They quote about sub 4 mins! must be laboratory?

Evening Ron,

I have a P/house but must confess I've never bothered to time the billyboil. I am probably doing other stuff while I wait and not in all that much of a rush but you have piqued my interest now and will time it next time out - early next month on the central Coast of NSW - so it will be faster there than at home cos it will be warmer haha

did you start with hot or cold water

if it was boiling hot to start with ..i think something maybe wrong
if it was only hot i still think something could be wrong
if warm....mmmm
if cold... well, i dunno
if freezing cold ...you did say you had it at full tilt...does that mean you were on an incline or the valve was opened fully and at maximum tank pressure...not too sure what you mean here old boy

its a tad hard to answer Ron, with out knowing the following

at what temperature was the water when you started?

I wont even ask about sea level thingy

but one thing i have noted with mine is that the support plate seems to be a lot higher above the burner than on gas stoves...this too suggests that it may take longer as more heat escapes from under any pots etc.....also a high pot will lose more heat while its getting hot compared to a low wide one....

Nudie,

Started with totally cold water.

Dont know sea level but not greatly elevated.

full tilt / max noise / flat chat / high flame.

Dont think there is anything wrong with it was just curious as to how long others take.

7.5 mins is a long time to wait on tea in morning! but better than waiting on a gas bottle defrosting though.

Also, at a higher altitude- it would take longer to boil than (say) at sea level.

I always thought at a higher altitude (less pressure) water "boiled" quicker because the bubbles could form more easily but the boiling temperature would be less than 100 degrees C.
But then it's a long time since High School physics. Must ask Dr Karl.
I think for practical purposes altitude isn't going to make an appreciable difference.

"I had the lid off so I could see"

It will boil much quicker with the lid on.

Agree, but then you dont know the point it boils at, plus dont think it accelerates it that much.

Measuring how long it takes water to boil. Ummm some issues there I think.

Perhaps we could try and get an idea how long paint takes to dry.

I ran some tests on different stoves some time ago.
The Coleman Dual Fuel Feather Hiker running on ULP took 4mins 30 secs to boil 1L of 20C water at 20C air temp at sea level (still air) 200mm dia. billy with lid on.
Takes slightly longer on Shellite
Water boils at a lower temp at altitude (you can't cook potatoes on top of high mountains)

Well another interesting point there, mine is a fairly new replacement, so is shiny a bit.

never knew it was a factor?

so there you go, forumites provide info again.
