Love this idea, I want to try to build one a bit larger but use solar panels and water heater elements to heat the sand during the day. Heat for the basement.
Fabulous! You have a great, ingenious mind. You could try using silica sand. Apparently it holds more heat and is capaple of reaching higher temperatures more easily. Kudos mate!
I'm about to turn my 40 gal on it's side and mount wheels on it like a semi tanker. With a tall removable flue at the outlet end the draft will pull the heat sideways much slower and heat the tank more efficiently than straight up.
Apologies for late reply mine is the spokes creaking, you can put a dab of grease on every crossing spokes, could be your bearings try servicing them by removing your cranks, carefully removed the plastic part around the bearing, a knife is best' & grease the bearing race inside 👍 if they are worn & still crunchy then you may need to replace them.
@@leejones2511 ok awesome! I thought about replacing the bearings I've put a lot of miles on it at the beach the mountains everywhere so I'm sure that's it. Thanks for the info I'll check my spokes too I didn't think about the rubbing where they cross lol
Very good idea I was thinking on that same idea but I’m thinking of using used oil and a blower as a heat source keep up the good work your mate from the U.S.A.😬
Hay alguna razon , para no poder construir una estufa en la planta baja Y a trabes de caños llevar el calor hacia planta alta ? queremos ayudarte , el esfuerzo que estan haciendo es de locos .nos podras informar sobre el tipo de construccion ,es de madera o mamposteria la casa ? algo muy liviano seria una estufa de pellet casera tipo S .para calentar toda la parte de arriba o una estufa de aceite ,esta todo en you tube y veo que tenes la capacidad de soldar, podrias construir cualquier modelo. Ese mismo contenedor de metal donde construiste la bateria de arena ,lo pones arriba de una sola hornalla de la cosina y calienta el hambiente muy bien , aumenta su eficiencia con un ventilador que reparta el calor, es solo una idea para gastar menos gas que un calefactor de gas industrial
Right off the bat you're losing a ton of heat through that hole on top. You should wind the exhaust back down around your stove (if you want to keep all the heat in the medium), then again up and out of the room with cooled-off gases. Make sure you take care of liquid residues in the pipe.
I wondered about using just a metal bucket of sand placed on top of a multi fuel stove. I wondered if it would store enough heat while the fire is on to keep my mountain apartment warm until the next evening. Another option was to use a bucket of paraffin wax as the state change from solid to liquid would hold a lot more energy. What put me of a little was the fire risk.
So why not make two and just swap them out as one gets lower temp? Or just use them together doubled? Take the same hour of firing and just double the firing and heat to the home?
insulating the vessel is important. but yes, using resistive heat, placed in and around the center of mass is optimal. that wasy the sand on the outter area does in fact insulate that heat. using resistive elements, the temp can quite easily get over 600c
Insulated steel chimneys can easily be fitted as wall mount to any buildings. Besides, having an outdoor garden boiler stove and insulated waterborne circulation to indoors distribution is also viable if there´s a garden, that is. Opens for wood, coal, turf, oil, waste oils. All easily automated for an even fire run, or shock doctrined by intense fire and thermal batteried by as ex sand. Water circulation pumps can be bought cheap these days and they draw very little juice unless there´s big elevations..
I think if you can keep it on the Sack Truck (Hand Truck) for heating and leave it on that indoors would make this a one person job. You take it outside heating up on the Sack Truck, then pul it back off the heat and roll it right indoors into position would be a game changer. Simple, effective and with one person efficient. Overall that would be safer too.
Don't apologise my man, do recommend it. That damn government of yours wants everyone on all electric, with them controlling it too. What you've demonstrated is an excellent way of keeping warm, alive and not needing them as much. Well done.
Its literally forcing us Brits to be ingenius. I think you should do it differently. Run a copper pipe coiled inside that but fill it with something like water or waste oil and have that pipe go into your home and into other sand batteries ans then you don't have to move. Yours isore efficient simply because outdoors the law cant stop you burning any wood you like, but indoors they will fine you if your chimney has wet wood or treated/painted wood.
Love it. Wondering how you get it up the stairs? I've used trolleys with heavy stuff but just a couple of steps or so. I'm imagining a type of slide -like a builders' shute split down the middle made of metal dustbin sections or similar -with a pulley system to take the weight off -weld an eye bolt to the battery for a chain to pass through. Maybe one of those systems for lifting engines etc. The block/pulley would need to be bolted very securely to a joist or something. Just some ideas. Anyway, thanks for the very informative short film. Great to see slightly mad idea making sense :)
correction: an eye bolt (or two) for a HOOK to pass through. And probably need to bolt block to a couple of joists with a plate. I'll let you work out the decorating challenges around that. All the Best. Looking forward to updates etc
Really enjoyed your videos! Amazing what can be done. I love the humour too -Hand grenade hahaha! I'm sure your wife loves you really ;) Are those mushrooms life size and you are are pixies?
I thought about this kind of solution and whether it would work. Sand in the ground can retain heat for months at a time If you could route the exhaust through the tank, even have 3 or 4 smaller flues through the tank would provide more surface area for heat transfer for both heating and releasing For anyone with a property that cannot have or cannot afford a stove install this could be a very viable solution Kudos for the experimentation!
Boiler system too pipes. A heat duct run through a window with heater out side .I have a generators that run on wood that can heat 6 homes in Canada. Wood gas one wire bit noisy.
I’m working on a similar project and sand is good to 3000 degrees F. A rocket stove at the barrel will reach around 2800. For your setup, I’d recommend using a small fan to basically build a forge. That will speed up the charging time and use less fuel.
Is not working, well it will work but you thinking to small. I have one container of 5 kubikk i will use. Obviously need place it outside, charge it with heat from wood and use pipes running inside in spirals to take out hot air and water
Why you call this "sand battery"? This is called mass heating. This is not free heat at all. You are using energy source to heat up the sand. The sand just stores and releasing the energy what you are put in the system to heat up. I see in the comments... there are a lot of people with ZERO knowledge in physics.
To save me trying to explain that free means it costs me nothing to heat (money wise) =free & Google sand battery & see what it comes up with. It may not be a battery as per say but I can confirm it's called a sand battery, But for arguments say from me & my fellow commentators for you we will call it - a potato 👍
Thermal mass or Heat battery... JUST THE FACTS All Materials have whats called K value or thermal mass value.. Kind of or basically the inverse of R value in insulation ratings. This K value is the amount of heat that can be stored in any Material. BY the way the unit of measurement is based off of water having the thermal mass of 1. This is the standard. Numerous charts can be looked up, and referenced for verification. Water has a thermal mass of 1 as mentioned HOWEVER rock only has .2 or one fifth of the thermal storage potential of water by Weight. Rock is more dense Pea gravel has 95 pounds in a cubic foot. BUT water only weighs 63 pounds per cubic foot. This weight advantage of Rock VS the HIGHER thermal storage capacity of water Results in WATER stores 3.26 times more heat per cubic foot than pea gravel. Even HEAVY dense stone solid Marble is only 150 pounds a cubic foot and STILL does not beat water for BTU storage. It takes about 1340 BTU to heat one gallon of water from 40 degrees F to 200 F That means a 55 gallon drum of water heated to 200 would let off about 77,000 BTU's of heat before it went back down to 40 F. To get the same heat storage you would need to heat Four 55 drums full of stone to store the same amount of heat
If you have a fireplace you could burn it in the room out from the fire place and pipe it up to vent out the chimney so you get the heat from the fire and the battery without losing heat up the chimney. You could also put metal mesh inside the pipe area to get extra heat from the flame that goes up the pipe in the center of your battery.
Nice idea. Try to convert your sand battery to 2 or 3 shorter sand batteries that can be fixed in top of each other. It will be easier to transport from your apartment to your yard
LPG is a lot more expensive than piped gas. Be careful using un flued appliances they can use the oxygen in a room and kill you with Co poising. It will also create loads of condensation which can cause problems with the structure of the house. Definitely do not use in a bathroom the air will soon be depleted of oxygen due to higher humidity and it will kill you. Did you use silica sand? Use a series of heat sand batteries for more efficiency. You could improve your burn rate by modifying your air intake somewhat. Thanks for the video keep warm but be careful.
You might be able to get a small propane tank, clean it out, and fill it with sand. Then build a stand and set it above the big wood burner and capture the heat
