This project goes over the installation of a homemade radiant floor hydronic heating system for the garage. The radiant floor heating uses a pex tubing that is installed along the floor of your garage or room . Hot water is passed through the tubing which radiates the heat out into the room or space.
The first step is to figure out what size pex coil tubing and how big of a water heater you would need . Also how many feet of tubing would allow enough heat to exchange into the concrete floor to sufficiently warm up the entire space. The total BTU/hour or heat required will be based on the square footage of your garage or room .
We begin by levelling the ground and start laying down a vapor barrier .The vapor barrier is made out of 6 Mil Visqueen plastic PE film .The barrier keeps the moisture from under the ground to rise up to the surface of the floor. We then lay a mixture of sand and packing gravel before installing the two inch extruded insulating polystyrene foam on the floor and the perimeter.
Four circuits of 800 ft half inch Pex tubing is stapled down on two inches of polystyrene insulating foam using a pex stapler. The eight tube ends are routed upto to a box from where it is connected to a manifold which is mounted on to the wall. The pex tubing with the supply and return tube is connected to the manifold with the help of a compression fitting .
To check if all the connections are OK or if there is any hole or leak in the tubing, connect the manifold to a 100 PSOI air pressure gauge to do a pressure test. Five inches of concrete is then poured over the pex tubing circuits. Saw cuts of less than an inch are made into the concrete to allow for the shrinkage during the curing process.
To insulate the pex tubing and to prevent water from entering into the floor, an expanding foam sealant is filled near the junction where the concrete meets the supply and return tubing near the manifold.
The heating components of this system are mounted on a 4 X 4 square sheet of plywood. The heater has a rating of 7.2kW . The heater is flow activated which requires a circulating pump to pump water through it which then activates the heater based on the temperature setting.
Two 120V fractional horsepower circulating pumps are used , one for running the water through the heater and the other circulates out through the pex loops. The pump has an inbuilt garden hose connector system used for draining.
The hot water coming out of the output end of the heater passes through a pressure tank which removes the air bubble with an air release valve and prevents any water hammer to the system.
This is further connected to the flow activated circulating pump for the heater with connections for filing and draining the system with the help of shut off valves. The water then comes down to a stainless steel manifold and then flows through the supply end of the pex tubing . The heated water splits into four supply loops at the manifold into the concrete floor.
The water then returns back to the return end of the manifold through the other four loops of pex tubing and goes straight through another circulating pump and a Y strainer filter before circulating back to the heater.
Two thermometers are connected at the supply and return end of the pipe to know the temperature difference of the outdoing water and the returning water. The flow is controlled by a thermostat and a switching relay that turns on the circulating pump .
- How to set up a Complete Off the grid living System using Solar and Wind Turbines . Make your own Power and never pay for electricity again.If you're going to run your home ,cabin or garage off grid, you are going to need some way of having power. Enter Solar and Wind. This project goes over the build of a complete off grid power generation system that can harness the clean and green renewable energy of the sun and the wind. Here is the basic rundown of the system .We go from sun to solar panels, there is no limit on how many solar panels we can put. It goes into a charge controller, it helps the solar panels create really efficient electricity to be pumped into your battery bank. Charge controller also makes sure that the batteries are being charged correctly and stay optimum. So solar panels to charge controller, and then that goes directly to your battery bank. The other source of renewable power is wind. The wind turbine is connected to a stop switch that goes into your battery bank. In some cases in between you can put up a wind turbine charge controller. Next step is converting the DC power to AC power with an inverter. The inverter basically converts the power to make it usable for your home. The inverter also has to be sized appropriately. From inverter to breaker panel which spreads the the power out throughout your house through your light switches, wall sockets. From breaker panel straight to your house or cabin. The first step is sizing your system. The battery voltage is going to determine what type of equipment you are going to be buying, and how you are going to be wiring your battery bank. So if you go with a 12 volt system, then you are going to want to make sure that your solar panels are wired up correctly for 12 volt. Even when you go with a wind turbine, you are going to want to make sure you buy the correct wind turbine for your battery voltage .So everything has to be sized appropriately so that you can collect as much energies as efficiently and then you can draw that power out. The golf cart batteries in my system are of 6 Volts. I have 6 of them wired in parallel, and in series to give me a 12 volt battery bank. The control panel box consists of my charge controller, voltmeter and 2 ammeters for both reading both solar and wind power amps. Four 12V Solar panels , each 100 watts are wired together . All the positives are connected to each other and all the negatives are connected to each other. The wiring goes straight into the control panel. The wind turbine used here is also 12V.The 3 Phase connections from the turbine goes into the bridge rectifier. The negative connection from the rectifier goes straight to the batteries, the positive goes to a junction box that connects the turbine and the inline fuse and 50amp breaker. The negative of the inverter goes into the negative of the batteries ,positive to positive. The romex wire from the inverter goes into the breaker panel in the house. The Permanent Motor Alternator turbine stands on a 6 foot pole .We have these two steel pipes that go down into the ground, three feet. There's another piece of steel that runs across here that's welded together, and it's in the bottom, and then we poured concrete over it to anchor it. Three tie down points are connected to the turbine to keep the pole steady from rocking around especially in high winds. So that way, when the blades turn, the bearings don't get worn out prematurely from wobbling. The Permanent Motor Alternator (PMA) used in this turbine consists of 2 shell casing, two bearings, a rotor inside and a stainless steel shaft. The tail of the turbine is made from a sheet metal cut to look like a fin.It is attached to a steel pole.This is further connected to the PMA alternator. The 11 blades of the turbine is attached to a hub and a pulley through a steel shaft. The belt is connected to a secondary pulley which is connected to the Permanent magnet alternator. The wire from the PMA is connected through MC4 connectors to the control panel. https://www.youtube.com/watch?v=4zi99DBWW0o Wind turbine and solar power system overview : https://www.youtube.com/watch?v=jT8yswXdxFk https://www.youtube.com/watch?v=uXKDy_BgdL0 https://www.youtube.com/watch?v=3DRfsjyCPXM https://www.youtube.com/watch?v=WTN7cMLE0ec Setup of the wind turbines : https://www.youtube.com/watch?v=QDUxNU8t-TU
- 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
