      Agreed. We have a wood burner and I saw an amazing book in the library called 'Norwegian Wood' (like the Beatles song). Its all about proper seasoning, storing, cutting of firewood, and written by a Norwegian and they know their stuff being partially in the Arctic Circle. It also gives the different heat strengths for types of wood, and how best to use wood burners. One really important fact is that wood is actually really clean to burn if done properly -get a good smoulder going for about 45 min with the kindling before adding the main logs and set the vents right etc etc. Yes, all governments should read it.

      A law was past that the smoke from a chimney can be monitored, but in that law a fire outside your home isn't included. So, you can have a bonfire outside your home burning any wood you like, even damp wood, but as soon as you're indoors, no damp wood, no wood that's chemical treated, so wood burners won't ever be banned because they're carbon neutral. They will control what you burn because one of their donors will have a company selling wood pellets or smokeless fuel.

    Efficiency tip? Make three or four smaller and lighter sand batteries that stack on top of each other. You can stack them on the burn chamber and heat them all at once. Then you can heat several rooms quickly, or stack them up in the hallway to heat the house for a long time.

    The " surplus" heat you could coil some copper tubing to heat water and store it in some thermal buckets. In Asia we use those buckets to store hot rice. You could find em at some asian stores in the uk.
    Water can be used to shower with a simple 12volt pump 🙂

    Have you tried adding another lift off pipe to the top of your chimney ? This will will increase chimney draft, burn your fire hotter and, provided that the sand can absorb and dissipate the heat within the battery fast enough, will I suspect significantly reduce burn times, An easy thing to try if you have spare pipe. Great video - thanks.

    I wouldn't say you're rambling at all . Sorry to hear what you guys are going through in the UK . We're having our own issues to deal with in the US with rumors of selective blackouts etc ,so videos like yours are becoming very popular with lots of people thinking about alternative energy ideas , prepping for themselves and their families in these times .
    I like your ideas and the build quality .
    I'm sure there's ways to improve upon this design but obviously you're on the right path and seem to be open to new ideas and suggestions .
    If you haven't already heard of gasifiers , definitely look into it . There are loads of great ideas and designs out there which may or may not fit what you're looking for but definitely worth checking out .

    Hi Lee
    That's great! Really appreciate you sharing this as I'd been having ideas the same.... I've just filled a wood stove up with sand (can't use in my location) and bought some 12v 28w PTC 220 degree ceramic heated elements to stick in the Sand and run direct of some solar panels... I'm also gonna make something very similar to your burner and fire it up in my workshop to provide some heat in there before moving it into the house 👍

      I'm doing the exact same thing except the heating element is a 3kw 240v unit from a water heater. At 12v it draws about .75a and at 24v it's drawing 1.5a. It's very slow to warm up but it works. If I can find another, I'll shove it in there.

      the solar panels are a great idea. not as efficient as using the heat from the sun directly (evacuated tubes) but if you know an installer and can get 2nd hand panels for nothing (easy) then it solves the issues of incompatible voltages (most grid tied systems run 36v panels... most offgrid systems dont).
      you can go further... nichrome wire will happily hit the 1000C mark. it is used in kilns after all. just need a bit of maths on diameter and lengths. like i needed 30M approx of 2.5mm to hit 16R for about 8A at 240V for my friends kiln recently. x2 for two phases. a lot of winding!
      iirc... dont quote those figures. it was a year ago.
      i just got a little 30W ceramic heater for lighting my furnace... it glows red hot, safe to 1000C. shame my furnace hits well over 1600C...
      im thinking of wind power though.
      using a fet, you can regulate the load on the turbine to match it perfectly to the wind speed... at all wind speeds. no worries about too little or too much. just dump it ALL into the thermal mass. cant do that with batteries. with an oversized genhead on the turbine you can keep it spinning even in a hurricane and its not going to overspeed.
      and then?
      if you have something at 200C plus, boiling water is a breeze...
      and boiling water makes steam.

    @thegwolf Před rokem +14

    Don't know if anyone suggested yet, but if you would change the firebox to a smokeless secondary combustion design, you'd increase the burn efficiency of the wood you use.
    As you said the flames on the top are quite neat looking, but they are also a neat way to show how much heat energy you waste.
    More efficient burn equals less burning time required to heat to the same degree and less wood used.
    The flames and the hot air above it is all going out into the environment instead into the storage.
    As for the storage as others mentioned in this comment section some tubing through the sand inside would allow a quicker release of the heat, but I guess it depends if you aim for heat retention and longer duration of release it might be better the way it is.
    Unless you channel the exhaust of the firebox through an internal tubing of the storage, because then heat gets more evenly distributed in the sand, possibly making the heating up part more efficient.
    But I suppose that'd be an entire version 2.0 of the project :D

      Agree although a Slow low temp burn like charcoal manufacturing would be more economical. Letting something get to 500deg plus is just wasting energy . Ok that depends on how cold your room is etc . When we’re out of heating oil we sometimes use a small cheap 1800w electric fan heater , believe it or not that’s enough too heat a large kitchen with a hallway and a small bedroom. 2 are enough to heat our bungalow to quite a nice temp . Don’t REALY have the time to experiment with stuff like this at the moment but I’ve just seen a sand battery with an electric heating element in it ran from solar panels . Pretty good . No different than electric underfloor heating so why not use an insulated slab of concrete with trace heating , not hot enough to crack the concrete and could use solar as partial power . Romans used to duct hot air from fires under floors so nothings new really 👍🇬🇧

    Great video Lee. The mantle idea is absolute genius to convert the waste gas to radiant heat. If you used concrete with a rocket stove principle it would probably heat up quicker with less fuel although it might dump the heat in your room too quickly making it uncomfortable. Thanks for sharing! (Just found out clay can store 50% more heat than sand/concrete). I think you're on to something here for homes with wood stoves - I think an internal larger clay rocket stove version could heat water and the room for a whole day from a 2 hour burn!

    I live in a small old house in the Netherlands. I started applying door and window draft strips and pur foam to close up all the draft holes and gaps that I could find on the entire down floor, including the inside doors, and I insulated the down floor ceilings with a couple of PIR insulation boards and pur foam, and that made a huge difference. It was a relative warm winter, but compared to previous years I only used half the amount of gas. And with the current prices that is going to save me between 2000 and 3000 Euro just this year.
    I really recommend every person to apply door and window strips, because for a relative cheap investment you really get a lot of gas savings and comfort in return. It is truly a huge difference. And once you start closing up gaps you will find even more gaps because they will be easier to detect as your house starts to feel more comfortable. I am not a rich person. So I do everything that I can do to save gas. And I can monitor my gas usage and the average outdoor temperature by the hour, week, month and year. And I can compare previous years with this year, so I have a very accurate insight on my usage. And I check it every single day.
    I bought the PUR foam and strips from the Action store. It is cheap, but it did the job. Half of the PIR foam boards were 50mm and for free, and the other half of it was 80mm which I bought at the hardware store, but I managed to get a discount from the manager. I always ask for a discount, and sometimes it works, and sometimes it doesn't. I only needed to buy 5 extra boards because I have a small ceiling.
    It is an investment that might be expensive for some people, but for me it already payed itself back, and it feels much much more comfortable. It is truly worth to make that investment. Even if you can't buy the thickest boards.

    That's a totally cool idea, I was reading about the project in Norway that is heating something like 100 homes and a public swim pool with a sand battery. So, great idea. I could see that with a few modifications you could increase the stored heat and reach that condition faster and if you could invest a bit you could extract the stored heat and convert it to house heating and return on your investment shortly. I think they said their sand battery is nearly zero maintenance and can work without repairs for nearly 50 years. So, thanks for sharing mate and accept my thanks for your video.

    Genius mate. I think these sand batteries have a big future. A German modern electric radiator company fills their rads with silica which is basically sand in a sort of modern version of a storage heater. I had the thought of stripping an old storage heater, taking the electrics out and sitting oil candles/lamp under each updraft vent to slowly charge up the bricks all day then later open the outlet vents and let the heat out. Or same idea with a row of 2-3 ft long cast iron pipes with end caps on them and a row of wicks in a long oil container underneath with bioethanol to create a more instant radiator.

    Great idea. I would wrap it in fiberglass and protect it from the weather, move it closer to the house, bury a large, double wide coil of copper tubing in the sand, insulate it, charge it with automotive antifreeze and connect it to a car radiator through a 12 volt pump and fan inside the house. You could build a decorative case for the inside hardware out of wood as it won't get hot enough to scorch it. You can run it with a 12 volt power supply, battery charger or, if the power goes off, a deep cycle marine battery. You can keep stoking the fire and use it full time. I would make the fire box taller or wider for a larger charge of firewood.
    If you have an electric central heat unit, you could adapt the radiator and install it in place of the heating coils like wood boiler type heaters do.

    I really like the idea of this. I've been researching ways to keep a greenhouse warm enough to
    keep plants from getting too cold. Of course along with something like this sand heat battery,
    a reflective cover/curtain with some dead air space behind it would also be in order to help
    prevent it from letting the heat just radiate right back out through the greenhouse's clear cover.
    I thought about using water filled barrels to hold heat but there are some serious limitations to
    that approach. Water has several ways it can easily be heated, but it can only be heated to just
    below boiling point of100 degrees Celsius (212 degrees Fahrenheit) before it begins to boil away,
    whereas the sand can be heated to far higher temperatures.
    I wonder if it is not too crazy of an idea to use solar to heat a barrel of sand with something like
    a 3 meter (about 10 feet) parabolic mirror (when sunlight is available)

      @@spencerchristie4000 Yeah, I saw something like that somewhere. They covered the greenhouse with a clear plastic envelope and kept it inflated with a smallish fan that needed to run all the time. As I recall, it didn't take a big fan because it really didn't need much to keep it inflated once it was filled... but it needed to be sealed good else it would leak air and not work very well. The air blown in came from inside the greenhouse, but I don't recall that air being heated before being sent into the bubble. Lots of dead airspace and air doesn't conduct heat very well. And with that airspace covering the majority of the structure without touching anything except at end edges, there was minimal heat loss due to so few thermal bridges.
      A reflective barrier would help prevent heat from radiating away through the clear covers. Preventing heat loss through those kinds of measures would mean not as much generated heat would be needed to maintain a given temperature inside. I was thinking Mylar reflective sheet could be used. Fairly light weight and can be procured in long rolls.

    It seems like a scaled-down version of a HAHSA. Have you considered putting it in an insulated structure such as a small storage shed maybe 3'×3'×4' with a duct carrying air through it and insulating where it is outside? It should require no more than a small fan (such as the ones used in automobiles without air conditioning) to circulate the air. It would probably work just as well if not better. That system should work well with a pair of deep cycle marine batteries and a solar charging system that could be augmented by a small inexpensive wind generator and for the occasions where there was no wind or sun for more than a day, you could charge with a regular automotive battery charger in a couple of hours. This is just something to consider if you haven't already. The entire system should be fairly inexpensive for the benefit it would give you.

    If your choking the flue you also need to restrict the air in, this way it will burn much longer and cleaner, it will take you longer to heat the sand but you will use less wood and create less smoke..
    I think it would be worth having this installed with a flue type metal chimney exiting either the wall or the roof directly above, you don't need to use the old broken chimneys. I'm thinking bigger gas bottles all the way up through 1st and 2nd floor from ground to top ceiling.
    I guess the disadvantage of having it installed with this configuration is that the inner heat released would be going up the chimney all night after the fire goes out. You could have an insulated flap that closes but there are always some cinders that need a vent so it would need 2x chimneys so you could close one at the top and open the other one for the fire to finish burning out, might have to loose that inner pipe as a heat vent or find a way to avoid ash blowing up into the room if you did open it once the 2nd chimney was switched in.

    For a sand battery you would want a lot more sand to heat up. Most central heating systems are transferring heat with water which has a much higher Specific Heat Capacity than sand does (water contains more energy per degree than sand does). The benefit for sand batteries are: a) sand is cheap b) sand is stable at much higher temperatures than water. Good work with the experiments.

    What I would love to see, though, is more precise temperature measurements (a laser IR thermometer is under $25 USD), and how effective the sand battery is at heating a single room of known volume for a measured period of time.
    With supplemental heaters going in connected spaces, the actually effectiveness of the sand battery is unknowable. So, the lack of scientific temperature/time measurements makes it impossible for others to know whether they should try this solution or not.

      I suspect that the HVAC calculations will take into account all the room & temperature values, as well as the thermal storage capacity of a volume of kiln dried sand, the BTU's per hour of a wood fire, the efficiency of heat transfer from wood fire to sand, and the discharge rate of stored heat from the sand battery to the room air over time.

That calculator app is essentially doing the math for the homeowner and making a workable recommendation for what system capacity will deliver the heating/cooling needed to put the indoor air into the desired comfort zone.)

    "Sand is an insulator" that is precisely why it stores heat! That whole beach thing is just because only the top has been heated. Do a longer burn (burrow under the sand later in the day) and you will have more hours of radiant heat. A heat conductor heats up and loses heat rapidly, the opposite of what you want. Plus, the more packed the sand is, the less of an insulator it is. Try pouring water through the sand while you are packing it (you will need to have a drain that you can seal afterwards) before you weld it in to the container, this will pack the sand as closely as possible.
