6 Low-Tech Winter Greenhouse Heating Techniques
1. Passive solar heating:
Passive solar heating takes advantage of the natural heat of the sun. Windows or other openings are placed on the south side of a building so that the sun can heat the building in the winter. Thermal mass, such as a brick wall, can be used to store the heat and slow the release of heat into the building. In this design, the greenhouse is oriented so that the long side of the building is facing south. This will allow the most direct sunlight to enter the building. The windows on the south side are larger than the windows on the other sides, and they are also positioned higher on the wall so that they can capture more sunlight. The roof of the greenhouse is also sloped so that it will direct sunlight into the building. In the winter, the warm air inside the greenhouse will rise and escape through the roof, and the cold air will be drawn in through the windows. This will help to keep the greenhouse warm.
2. Earth sheltering:
Earth sheltering is the use of the earth to provide thermal mass and insulation. The earth can be used to surround a building or to cover the roof.
A greenhouse can be heated with an earthen shelter. The shelter can be a simple hole in the ground with a cover, or an elaborate structure. The advantage of an earthen shelter is that the temperature inside the greenhouse can be more easily controlled than if the greenhouse were open to the outside air.
The temperature inside the greenhouse can be raised by adding insulation to the shelter. The insulation can be made of materials such as straw, leaves, or newspapers. The insulation will help to keep the heat from the sun inside the greenhouse, and will help to keep the temperature inside the greenhouse warmer than the temperature outside the greenhouse.
Another way to heat a greenhouse is to use a heat lamp. A heat lamp can be used to heat the greenhouse even if the temperature outside the greenhouse is cold. The heat lamp will help to keep the temperature inside the greenhouse warm.
3. Greenhouse heating:
Greenhouses use glass or plastic to cover the roof and walls. The glass or plastic allows the sun’s energy to heat the greenhouse. Greenhouses can also be heated with a furnace or other heating system.
Windbreaks are barriers that are placed around a building to block the wind. Windbreaks can be made of trees, shrubs, or other objects. A windbreak is a barrier to the wind. It can be made of natural or artificial materials.
Windbreaks are used to protect people, animals, or plants from the wind. They can be used to protect buildings from the wind, or to protect crops from the wind.
Windbreaks can be used to heat greenhouses. A windbreak can be used to create a wind shadow. This will block the wind from hitting the greenhouse. This will help to keep the greenhouse warm.
5. Solar collectors:
Solar collectors are devices that are used to collect the sun’s energy. Solar collectors can be used to heat water or air. Solar collectors for the heating of Greenhouses are devices that use the sun’s energy to heat a fluid. This heated fluid is then used to heat the greenhouse. Solar collectors for the heating of Greenhouses come in a variety of shapes and sizes. Some are mounted on the roof of the greenhouse, while others are placed on the ground near the greenhouse.
6. Geothermal heating:
Geothermal heating uses the heat of the earth to heat a building. A geothermal system uses pipes that are buried in the ground. The pipes collect the heat from the earth and use it to heat a building. The earth’s heat is used to heat water, which is then used to heat the building or greenhouse. This is an environmentally friendly way to heat a building or greenhouse, because it does not use any fossil fuels.
