Everyone knows that free cheese is only in a mousetrap. Unfortunately, this also applies to the free heating of the house. At a minimum, you will have to spend money on consumables and spare parts for the construction of a heating system. But the idea of heating a house with free energy prevails over many owners of country cottages.
The most affordable source of energy for heating
The sun is an inexhaustible source of energy available to all. In mid-latitudes, you can use it as free home heating from mid-spring to mid-autumn. When the sun is at its zenith, the power of the self-assembled solar oven reaches 1.5 kilowatts. In the daytime, the stove will warm the water for bathing and household needs, and at night, using energy from the battery, you can heat a small room.
The main components of a free heating system for a private house:
- Expansion tank;
- Water accumulator;
- Collector.
Tubes are laid between the nodes, a closed loop is drawn up. The free heating system of a private house operates using the principle of thermal convection. The dark tubes of the heat exchanger capture the energy from the sun's rays, which the water absorbs. The volume of warm water increases, it flows into the water accumulator, instead of it, unheated water enters the tubes. Over time, the water heats up more and more. A video about free heating at home can be found on the net.
Solar heating collector
This node of free heating of a private house with your own hands is the most difficult to assemble.
The collector is a body made of wood and a heat exchanger (tube). You need plywood 6 millimeters, board 40 millimeters, fiberglass, galvanized sheet 1 millimeter, pipes for water supply systems.
The size of the sheet that concentrates the heat is 2.2 m by 70 cm. From two bent pipes (diameter 1 inch), you need to assemble a frame 2.1 m by 60 cm. Cut half-inch pipes into 12 pieces so that they fit tightly into the frame from the pipe. In the frame, make holes with a diameter of 14 millimeters in the amount of 13 pieces. The distance between the holes is 15 cm. Weld everything together - this is the heat exchanger. With the help of a thin wire, a sheet of metal is attached to it, everything is covered with black paint in several layers. There are no special difficulties in constructing free heating of a house with your own hands.
Collector housing
Heating your home with free energy is now a reality. A body with a plywood bottom is hammered out of the boards. Lay a layer of insulation on the bottom, a heat exchanger is placed on top and a transparent glass is installed on top. The housing must be sealed, rain and melt water getting inside will impair the operation of the device. A sturdy hinged cover must be installed on top, which will not allow hail or falling branches to break the glass. The mirrors installed on the lid will speed up water heating and increase efficiency. Materials about free heating at home videos in large quantities are laid out on various sites.
