This project goes into the build of an outdoor wood boiler for heating your garage using an old barrel and a car radiator. The first step is to make a wood burning stove out of an old barrel . Here we are converting the barrel into a stove using a vogelzang stove kit.
We start by cutting a hole for the door using the the door accessory from the kit as a guide. Place the door on the side of the barrel and mark the four corners. Start cutting the hole using a grinder, reciprocating saw or a plasma torch.
Align the door with the hole and drill holes for the screws. The door is now secured in place .
Next step is to install the legs that came with the kit. Place the barrel on the the legs and align them so that everything is level. The spots are marked , holes drilled and the legs are bolted in place.
To control the air flow and how hot the stove burns, we install the flange and the damper within the chimney area. Center the flange that comes with the kit near the edge and make a circle for cutting the hole. Also mark holes for the bolts using the flange as a guide. The flange along with the damper is then screwed down securely.
The next step is to convert this barrel stove into a hot water heater. Begin by drilling two holes across both sides of the barrel and inserting couple of three eighth inch threaded rod across the sides. This creates a base where a 30ft coiled copper tubes are placed to circulate the warm water.
A 30ft half inch copper coil with the input and output straight end is placed inside the barrel on top of the two threaded 3/8th rod base which we have installed previously. Two holes are drilled at the back of the barrel so that the input and the output ends of the copper coil can be connected to a pipe or flexible hose.
The input end of copper coil coming out at the back of the barrel is further connected to another loop of copper coil outside the barrel . The coil is wound across the barrel so that incoming water is preheated using the outside coil before it goes into the barrel and gets further heated by the coils inside .
The ends of the coils are connected to two pipes, the outgoing and the return . These pipes are then insulated using half inch pipe insulation foam to prevent any leak. A small trench is dug and the insulated pipe is extended to the garage.
The water circulatory pipes are now connected to an old car radiator inside the garage. The incoming hot water pipe is connected at the top of the radiator and the return is connected at the bottom.
To circulate the water ,we use a cheap submersible pump. The pump is submerged in a bucket . The pump will pump cold water out through the heater, the hot water circulates through the radiator , cools down and collected at the bucket and it is again recirculated.
Two holes are drilled on the top of the bucket . One for the pipe coming out from the pump and another for the pipe coming back from the radiator. The inch and quarter radiator hose is adjusted to connect to the pex hose piping with the help of a PVC poly tube with a threaded end
The other side of the polytube with the threaded end is attached to a PVC adapter and a slip fitting with a bushing. This helps us to connect the pex pipe to the radiator . To prevent the water from boiling , an antifreeze solution is mixed .
A window fan is used as a back fan for the radiator. Placed right behind the radiator, this blows the hot air through it and into the garage.
- How to build a Homemade Micro Wind Turbine for under $50 that can be mounted anywhereThis project goes in the detail on how to build a mini wind turbine..The wind turbine is a nice addition to your solar generator system for times when it’s cloudy and you are not receiving as much sunlight as you normally First step is to build some cheap PVC blades, what kind of motor we're going to be using and how we're going to attach this to the motor. We are making six blades or rotors here.What we want to do is we want to cut our PVC pipe to length first. Once you've got it cut to length, then you want to take your your straight edge again and and Marco line down the center and cut it in half. Make sure that you do that on both sides. One on this side, one on this side. And that they're perfectly in the middle so that you'll get two even sides. We need to cut a small little block down at the blade end, where we are going to put a drill hole and put a screw through it so that it attaches to the hub.On the top of the blade, we're going to cut away some of the material to resemble a swept wing, kind of at an angle. These are 14 inch long blades that is attached to the hub using set screws attached to the motor. The 12V motor used here is a 300 RPM geared motor which would be its maximum speed and it produces 600 milliamps when its fully loaded. The motor is placed inside a One and half inch PVC pipe ,another PVC Tee is connected from where the wires will down to the bottom where another 7 foot pipe that act as the tower or pole. The end of the pole goes into a shower drain which is then attached to piece of wood that acts a solid base. For the YAW system at the back end,a tail vane is made of a cheap flashing material that is bolted between an 8 inch piece of PVC.Put a hole through the middle of it with a bolt in between so that it can't move anywhere. We use an an old OSB for the base, size is about seven inches square. And then I just have a piece of treated lumber on the bottom. It's attached to this ball bearings so it can spin around. The Shower drain PVC is placed in the middle through some ball bearings. Route the wiring down through the hole for to connect to the charge controller. Next step is the wiring through the piping.We just need to connect these terminals to the appropriate sides of the motor. https://www.youtube.com/watch?v=6UZ2WtXlVoc https://www.youtube.com/watch?v=fjHW78bMUoY https://www.youtube.com/watch?v=c7a9RSzZKcE
- DIY Video:How to build a Homemade Double Barrel Garage Heater out of Old Water Tanks .Efficient,clean burn and cheap!This project goes over the build of Double Barrel Stove out of two old scrap water heaters for the shop. The first step is to disassemble both the old electric hot water heaters to get their tanks out. Take a grinder and cut a section off from the top of the water heater tank. This tank will become the bottom tank. Remove any calcium and mineral that ends up developing deposits inside the bottom of the tank. Take a 12 gauge plate steel and put our top drum upside down and scribe a circle out of them from the end and cut it. Weld the steel piece onto the drum. You need to do the same for the other drum too because with these double barrels, you are basically making two stoves, just connecting them in the middle. Now both the top tank and bottom tank ends have been polished and cleaned .Remove any insulations, paints and glues from them if they have any. Make sure all the rough pieces on the tank are welded on ground down. Cut a small piece of pipe that acts as stack between the 2 tank. Next step is to add a small support bracket on the top of the bottom tank that will help support the top tank. Cut a hole on the bottom tank .This will be where the stack goes between two of them. Fill the drain plug down at the bottom . Take the top tank, cut and weld the top exhaust stack that will be six inch outlet for the smoke. We also add a six inch inlet that goes up to the top that forces your your smoke and the gas has to go across the length of the barrel. The bottom barrel will be connected to this. Both barrels are welded together, the bottom barrel is welded onto the mid stack which connects the top barrel with the exhaust stack. In order to support the barrels, we take the scrap pipes lying around and make legs as a support structure for the stove. Next is the door fabrication. We cut a hole for the door in the bottom barrel. A couple of hinges, door catch are welded on to this end. An air inlet pipe is threaded onto a plate. The whole unit is then attached to the door. A handle is attached to the inlet pipe so you can open and close whenever you want to control the flow of the air intake. https://www.youtube.com/watch?v=fTj4pjJ4DT0
- How to build a Homemade DIY Geothermal Heat Exchanger to Cool Your GarageThis project goes over the build of a Geothermal heat pump that takes the hot air in your garage and cool it down by transferring that heat into water .The cold water is pulled out of the ground through a shallow hand dug well and send to a heat exchanger inside the garage . A fan attached to the heat exchanger blows out the cold air into the garage . The heat exchanger absorbs the existing heat inside the garage . The warmed up water is then removed through an exhaust pipe. Just a few feet down the earth is a consistent 55 degrees, summer or winter. Water at that depth is about the same temperature. To harness the cold water down below, we dig a shallow well. To do this we use a post auger and a 3 foot long well point that is attached to a 10 foot three quarter inch pipe using a drive coupling. We start by digging a hole using the post auger till the water table is reached and then start driving using the well point for additional two to three feet until it is submerged under the water table. A two to three foot trench is dug from where the well is installed to the garage . A One inch poly pipe is connected to the well pipe using a barbed coupling and is buried inside the two foot trench all the way to a well jet pump .The trench is dug down at least two feet until you hit some hard pan clay that is about where the temperatures begins being more constant. This keeps the pipe cool under the earth. The other end of the poly pipe coming out from the trench is connected a 1/2 HP Flotec Shallow well jet pump . The pump can be powered by a solar panel. The pump is kept outside the garage as it generates a lot of heat. If it is kept inside the garage, cooling effect from the water will be undone by the heat generated by the pump. The output of the pump is connected to a three quarter inch copper pipe inside the garage. It is then further connected to a water pressure tank with the help of a brass tee and a union. A relief valve is also attached to the tee to empty the water tank if the pressure gets too high. A water pressure tank is used prevent the pump from failure .It also acts as a buffer storage. The other end of the brass tee is connected to two pipes. One pipe goes outside the garage to a faucet and the other pipe is connected to a radiator that acts as a finned tube heat exchanger. The heat exchanger captures the hot air surrounding the garage and stores the heat into the finned coils within the radiator .The heat is transferred to the water flowing through them . An exhaust line from the radiator carries this hot water to outside the garage. Two flexible hose pipes connects the input of the heat exchanger to the water tank and output to an exhaust pipe. A box fan is placed in the front of the radiator to blow the cool air . The fan can be powered by Solar panels. Once the water starts running through the radiator , we start the fan https://www.youtube.com/watch?v=IRLLbmcnYjA https://www.youtube.com/watch?v=bCOeMIQLwgc
