Question
Would a hot water bottle be a good option for emergency heat when the power is out, single-digit temp outside, etc.? Two quarts are a lot of water to heat with emergency fuel (without gassing everyone). What is the minimum amount of water that would be effective? Do you have suggestions for other heat sources? Thanks, Lee
Run for the hills Francis he’s about to start talking “science”
So here’s the problem Lee – it’s something called – Newton’s Law of Cooling
Newton’s Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).
A beaker of water is heated to a boiling point for an experiment in the physics laboratory.
The water inside the beaker reaches a temperature of 302 degrees F (150 degrees C).
“hey, wait, Mitch, water boils and becomes steam at 212 degrees F (100 degrees C) where the heck can you find 302 degrees F water?” – oy
You should have run with Francis when you had the chance –Â
Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 degrees C (212 degrees F), and the critical temperature, 374 degrees C (705 degrees F). It is also known as “subcritical water” or “pressurized hot water.”
back to the experiment-
After measuring the temperature, the beaker is removed from the burner and is then placed on the countertop.
The temperature of the surrounding air is measured to be 167 degrees F (75 degrees C).
The beaker of water is left to cool for three minutes and then its temperature is measured to be 248 degrees F (120 degrees C).
How many minutes more will it take before the water will cool down to a temperature of 185 degrees f (85 degrees C)?About 12.
Making my way on a final approach back to reality and an answer to your question.
Even if you had access to the flux capacitor from Back to the Future to heat the water hotter than you ever knew that water could be heated, Lee.
Using two hours of emergency fuel to heat water that will cool in, realistically about 30 minutes because the water is surrounded by insulated rubber-not conductive glass – would be inefficient and a waste of valuable emergency energy. It’s far more efficient to use two hours of emergency fuel to heat you and the bird which can be accomplished (without gassing anyone).
We advocate small catalytic propane space heaters.
They are highly efficient.
We have been using them for years – with our bird.
How did I learn that propane would be safe for our cockatiel?
Sometimes fact-checking on the Internet is counterproductive.
Researching the subject of propane safety and birds, once again proved the Internet is the best worst place for information.
About a dozen years ago,
I was told by an avian “expert” that birds should never be exposed to propane heat.
That always bothered me because I know many people throughout the country have no access to natural gas and rely on the propane distribution system by truck.Â
Â
We travel with our cockatiel popcorn to our travel trailer on a fairly regular basis.
One of the problems with travel trailers especially old ones are they’re terrible to heat because you’re basically in a tin can. We had insulation added in what we call a Hill William bump-out with wood studs and drywall.
Â
The problem was even on a moderately cool day when we arrived the trailer was always an icebox. For safety we used two electric heaters that took forever to warm up the trailer.
Â
So one day I tried an experiment with an infrared propane tent heater from our tent-camping days. I turned on the electric heaters and then the propane heater to accelerate the rise of temperature in the room. I opened up one of the two ceiling vents of the trailer and brought Popcorn in, watching her very closely.
Â
I kept a sharp eye on her throughout the evening and allowed the ceiling vent to remain open. It was getting pretty chilly out so I finally closed the vent still watching her – our trailer is not that big – a 25-footer. We were up for another couple of hours and she was none the worse for wear and I felt good about it. That was 4 winters ago.
Â
Catalytic heaters like Mr. Heater above will easily put out 30,000 BTUs and will run on a 1 pound $3 tank of propane for about five hours on high. That said, this miracle winter survival device can never come near a bird. Birds do not understand the concept of flame or fire. So the judgment call you are faced with is determined by the length of the power outage. If news reports say that power will be restored in a few hours, keep it simple, play it safe – don’t let your bird out of the cage while the heater is in use.
Â
If you are in a God forbid a situation like last year’s horrific snowfalls on the east coast creating power outages for days and you are unable to evacuate, you’ll want to have a strategy for heater placement to allow some “out of the cage time.” For example, in the trailer, we would put a heating unit behind the stool under the kitchen table and if the bird was out she was not allowed to go to the floor. Capiche?
Â
So you know me – the voices in my head start chatting and somehow come up with a recommendation that we should make our small travel trailer that’s permanently parked more “winter friendly”. Fast forward to this past spring and I now have two 10,000 BTU ventless heaters warming our 1784 cubic foot trailer It took two days to put in the heaters. It took six weekends to find where all the cold air was coming in. We even sealed up all but one jalousie crank window – jalousie windows are made of long narrow strips of glass that work like blinds and have no insulation value whatsoever.
Â
BTW – our neighbor in Indiana smelled gas one night – he works for a company that distributes gas. Always trying to do the right thing I called Amerigas to report the issue. It was 10:30 on a Friday night. The AmeriGas driver pulled up in what was probably just a little over 30 minutes. They take ANY reports of potential propane leaks VERY seriously. As it turned out the pipe dope around the threaded end of the meter on our 400-gallon tank had cracked and gas was in fact escaping. About two turns and it was fully tightened – it passed the leak test (soapy water solution over the entire area). That was impressive.
Â
So Popcorn is out of her cage as long as we’re with her in the trailer which keeps her happy and most importantly healthy. So much for an “expert” opinion.
Â
 “I help run a small parrot rescue and sanctuary in south-central Wisconsin. Feathered Friends Sanctuary & Rescue. We are in desperate need of help to pay for food for our parrots and propane for the coming winter. All our income is from donations, no one gets paid. Any and all help is greatly appreciated. Thank you.” Here’s an entire bird rescue in Edgerton Wisconsin, that is heated with propane. ’nuff said?
Â
Be it propane, natural gas, or electric heat you still have to deal with winter. We offer the absolute best selection of bird warmers so you don’t have to worry about heating the whole house just to heat the bird. There we go solving problems again.
