How to build an Off grid Rocket Mass Stove Hot Water heater using Copper Coils, Clay ,Sand. Also works as a cooktop!!!

    This project goes into the build of an off grid rocket mass heater for heating water without propane or electricity. This system also doubles as a cooktop. This rocket stove is really efficient and can create tremendous amount of free heat from little pieces of wood.

    The materials you need to build this rocket mass heater are copper coil , PVC pipes to make mould, clay and sand mixture, a frame for support, storage tank or drum ,oil, wood as fuel.

    The stove sits on a frame made from a wooden piece. Here an old chair is used as a base for support. The cob mixture made from clay, sand and water is poured on top of the frame as it is raised up.

    The next step is make hole for the air intake at the base of the stove. Also another hole is made for fuel intake at an angle to the base. We use PVC pipes as mould to make these holes.

    We lubricate the pipes with oil before covering them with mud so that they can be easily removed once the mould has been set and dry. A half cut lubricated PVC pipe is placed at the base of the support frame in front of another PVC which forms the body of the stove where the copper coil is wrapped.

    We start covering the PVC pipes with clay and sand mixture around the junction where the pipes meet. Once the mud has been filled and raised up , another PVC pipe at an angle is placed for the fuel intake.

    The copper coil is inserted into a well greased up PVC pipe . This section acts as the burn chamber where the coil gets heated up with the water inside. The coil is extended at the ends for the intake and the outlet .The bottom side of the coil is the intake of the cold water and the top for the hot water outlet.

    Fully pack the area around the copper coil and sides of the PVC pipe with the clay mixture such that the copper coils are completely covered . Pack the clay till you reach five to six inches above at the end of the pipe . This is done so that the top can be used for cooking or boiling.

    Once the clay and sand mixture is completely dried and set, we slowly take the PVC pipes out. Dig out the back end of both the holes so that all of them are connected to form a elbow shaped hole.

    The intake and the outlet copper tube is then connected to a water storage barrel. The intake pipe is connected near the bottom of the barrel where the cold water settles and the upper end of the copper coil is connected at the top where the hot water is collected.

    So the cold water that flows into the rocket stove, gets heated through the copper coil, and then due to the thermosiphon effect and natural convection ,the heated water is pumped through the other end of the coil on to the top of the barrel and this way the water is recirculated without the help of any external source. The cold water natural sinks down due to its higher density .The hot water becomes less dense once its heated , therefore it expands and rises up the coil to the water storage tank. Make sure that there is a height difference between the rocket stove and the water storage tank . The rocket stove always should be installed below the storage tank so that cold water naturally descends down into the stove and there is no backwards flow .

      This video shows a vegetable oil heavy fuel gasifier that I built in an attempt to fuel a gasoline engine with waste oil. Here i test this with an old lawnmower engine. In this video I use vegetable oil as fuel, but used motor oil should work as well.The other videos shows the build of a similar used motor oil gasifier that I built from an old fire extinguisher and some pipe. It works by pyrolysis.This one has an improved burner and sideways canister orientation.

    • DIY Video : How to build an Off Grid DIY 12 Volt Washing Machine from junk parts and pieces laying around
      This video shows the build of a homemade 12V washing machine made from junk parts and pieces laying around.Most of the materials you’ll need can be found around your house and most certainly at your local hardware store.Great for going off grid for a while preparing to be survive in case of SHTF or are you just a regular old camper that needs clean clothes at camp.Laundry has come up a number of times as a self-sufficiency topic. It makes sense for a couple reasons. First of all, because many people in our crowd are wanting to be self-sufficient of the electrical and water grids, and need find another way of washing clothes. Secondly, because we are also usually looking for ways to save money.
