camping storage heater from bricks, sand and an ammo tin. - home energy storage
Britain is suffering from bad weather.
There is a lot of snow in a country that is usually very gentle, remember that if there is more than 1 inch snow on the ground, people here lose the ability to drive.
This coming weekend, I will drive to half of the country and spend a long weekend in the wild with 2000 stupid people like me. (
I will also test my front stove)
So I decided that I would be comfortable and warm if I really had to sleep under the canvas. . .
I neither suffocated because of carbon monoxide nor turned my tent into a toastyflagation.
The solution I came up (
Except for ridiculous bedding on my camp bed)
Is to make a storage heater.
The principle is simple.
Objects with high thermal energy storage capacity are heated. . .
Then, when the heat source is removed, it maintains heat and heat dissipation for a considerable period of time.
Ceramic is often used in modern storage heaters. . .
But in this project, I will use house bricks and sand (
Fill the gap)
Important safety precautions and Disclaimer This manual deals with very hot items (
Such as fire, heated steel, brick).
Do not place storage heaters anywhere that may cause damage to people or property.
I'm not responsible for anyone making puppets.
Remember, you will expose this poor ammo tank to a lot of heat (
You're going to dump it on the fire). . . .
It may be a good idea to remove anything that is flammable or melted (
Technical terms there)from the box.
In the case of this special cartridge, there is a rubber seal on the inside of its cover.
So we need to remove this for two reasons.
First of all, you don't want the melted, smelly plastic to drop off the outside (or inside)of the box.
Secondly, if the box is sealed. . . .
You heat it up. . . .
Something very bad could happen.
Seriously, don't try this)
Basically, the box can't help but breathe.
I used a screwdriver to pry up the edge of the rubber seal and pull it out.
I'm sorry, but for some reason I don't have a picture of the brick in the box. . .
It is such a ruthless garden.
I found that the ammo tank of this size can handle about 3. 75 bricks.
The first three are well installed at one end of the box.
Leave enough space to get the last 0.
Finally, 75 bricks were squeezed.
The last brick requires a little pressure to be installed.
I had to use the Persuadertron 5000TM (a lump hammer)
Of course, I need to separate the brick first so that it is only three quarters, which is the normal length (
Use Persuadertron more this time)
Make sure that no brick exceeds the height of the top of the box. . .
Otherwise, the lid won't be closed.
I don't like the fact that I left all these spaces on the side of the brick.
I think it's just a waste of volume that might absorb valuable heat.
So I decided to dig some sand in it.
I am not going to describe how to transfer the sand from the bag to the box. . .
If you can't solve the problem, you really shouldn't try instructures (
Or use a knife and fork without supervision)
I have a very heavy metal box now.
I will put this thing on a campfire this weekend and move it to my tent a few hours later.
One thing is very important.
This thing will be very hot.
I will protect it by hand (
Probably a technique like tea towels)
Don't put it on anything that can burn.
My intention is to put it on a paving board or something else that is not flammable.
Never put it on the floor of your tent (
It will melt directly)
Don't put it anywhere someone might accidentally touch it.
If I do not die from a low body temperature, I will update the instructions for this process.
Please vote for me if you like this: people, please stay warm!
I did try this last weekend (30th March)
And it seems to work very well.
My only problem is the cold weather (allegedly -
Although I don't fully believe this, 10C one night)
Others object to pouring the box on a campfire (
It blocks so much heat).
The Hot Box is useful, but certainly can't replace a good hot water bottle under a lot of bedding.
