Every gardener wants to get an early harvest, but in regions with an unstable climate, spring frosts recede by mid-May. Therefore, to get fresh greens, radishes and early tomatoes with cucumbers, craftsmen have found a simple and cheap way. Heating a greenhouse with candles is an effective method used by many gardeners.
Benefits of heating a greenhouse with a candle
A candle has been a source of light since ancient times, but thanks to the Californian inventor and the inventions of gardeners, the candle began to be used as a heater for greenhouses and residential premises.
A candle heater for a greenhouse has several advantages:
- simple and cheap materials for manufacturing;
- improvised means can be used;
- original appearance, in the future can be used as a decor;
- making by hand.
Very often, gardeners use electrical appliances to heat the greenhouse. But candle equipment is in no way inferior to heaters and heaters. This is explained by:
- A wax candle weighing 120 g emits about 1,1-2 mJ.
- During time – 55-150 kJ.
The power of the mini radiator is from 15W to 42W.
How this method works
Candle heating consists of several ceramic pots of different diameters. Some are assembled into a nesting doll, others are put on a metal axis, on which nuts and washers are attached. Such a lampshade over candles makes it possible to capture, accumulate and give off heat to the room. Thanks to this construction, the flame of the candle heats up the rod and metal nuts, then the ceramics heat up, and the heat spreads through the greenhouse.
With a slight decrease in temperature to -1 ° C, 6 paraffin candles must be used to insulate a greenhouse measuring 3×4 cm. In a short time, the room will warm up to + 5-8 °C. To heat a larger greenhouse, it is necessary to install several candle heaters.
Preparation of containers and candles
Candle heating is an easy way to heat a greenhouse in the spring with a candle. It can be made by hand in a short time. To do this, prepare the following materials:
- ceramic or clay pots of different diameters – 3 pcs.;
- threaded metal rod;
- nut – 8 pcs.;
- washer – 20 pcs.;
- ceramic stand;
- heat-resistant support under the cap.
Making candle heating for a greenhouse, step by step instructions:
- A hole is made in the largest pot and an axle is inserted. Outside, the pot is fixed with a nut, the inside is fixed with several washers.
- String 2 pot, which is also fastened with nuts and washers.
- The third one is put on and fixed with the rest of the metal parts.
- Any heat-resistant material suitable in size can serve as a support for the cap.
- The required number of candles and a heat-resistant support are installed on the pallet, where the cap is put on.
If there were no ceramic or clay pots at hand, then heating can be done from cans of various sizes or from containers for bulk products. Manufacturing technology is the same as described above.
The metal cap will serve as protection against open fire and will accumulate heat. The gaps between the banks will allow hot air to circulate, and the heated metal walls will release warm air. By placing several such structures in a greenhouse, you can save plants on a cold night.
To save money, time and effort, gardeners are creating new ways to insulate a greenhouse in order to use it rationally and get an early harvest. The simplest and most effective way to heat is to use a candle, a tin can, and a bucket. The larger the candle and jar will be in size, the longer warm air will flow into the greenhouse. Preparation method:
- Several holes are made in the bucket, with a diameter of a thumb. This is necessary to circulate air around the greenhouse in order to distribute the temperature and humidity of the air.
- A jar with a candle is placed in a bucket.
- Vegetable oil is poured into the jar to the brim and the wick of the candle is lit.
To maximize the temperature, put several jars with candles in the bucket or install several structures.
How to heat a greenhouse with candles
The candle heater is suitable for small greenhouses. This design will not only save electricity or alternative fuel for heating, but also fill the greenhouse with the necessary heat.
Having installed a ceramic heater in a greenhouse, it must be remembered that the heat will fully begin to flow only after 3-4 hours. Since during this time moisture will evaporate from the pots. To heat the greenhouse up to + 15-20 °C, it is better to make several structures and install them in different corners of the greenhouse.
How often do you need to change the candles
Using this method of heating the greenhouse, it is necessary to use paraffin candles. On average, 1 candle burns for about 5 days, and then to maintain the air temperature, they must be replaced in a timely manner, and oil added. If you put 1 thick candle in the design, then it will last for 6-8 cold days to heat the greenhouse.
Conclusion
Heating a greenhouse with candles is a simple, efficient and economical way. To make a structure, you will need improvised materials, time and a little patience. But these works will not be in vain, since such heating will allow you to grow greens, seedlings in the spring and get an early harvest.
