A large percentage of the population prefers to go to the country during their summer holidays. Every summer resident knows that without a greenhouse, the harvest will not fully delight. Many crops require warmth, so we suggest looking at greenhouse heaters that can be used to harvest all year round. And in the spring you can get strong and high-yielding seedlings.

For greenhouse

Energy-saving mini greenhouses are quite popular today. You can choose an option with a thermostat, solar-powered (from the sun), as well as kerosene strip models with an air temperature sensor. When choosing a heater for greenhouses, it is important to understand at least a little what the equipment will be used for. The product market is packed with various types of similar products. They are so different that it is difficult for an unprepared person to understand and find a suitable device.

Let's analyze devices that will not hit the budget and will be easy to install. We considered providing a small greenhouse with sufficient heat to be an important factor in a good heater. Initially, you must decide what you personally need. In accordance with your requests, it is necessary to select a heating device.

In addition, you must remember about such a factor as the capabilities of the device. We mean the financial equivalent, the size of the greenhouse, the level of temperature conditions.

There are a few more parameters worth paying attention to

• heater power;
• efficiency;
• quality properties;
• the ability to minimize heat loss;
• special conditions of the purchased device.

When is it necessary?

Before answering this question, you need to identify the factors that are important to you. The most popular request of summer residents is to grow a large, high-quality crop. This is enough to tell you that you need a heater. If we analyze the question of what temperature is necessary to maintain positive conditions in the greenhouse, then several periods can be distinguished.

Autumn

The temperature should not drop below -1 degrees. This is one of the most important factors. In autumn, almost the entire crop is harvested; it is not always necessary to create tropical conditions for newly planted crops. Plants must be prepared for winter.

Spring

For high-quality germination and growth of seedlings, it is necessary to constantly maintain a temperature that is comfortable for the planted varieties. It is necessary to control the temperature manually. If it's a long winter and a cold spring, the temperature should be several degrees higher, since the earth does not naturally warm up.

Winter

The temperature is determined depending on which plants are planted in the greenhouse. If you do not use a greenhouse in winter, do not plant plants in the ground, then you do not need to turn on the device. If you grow any product, it is necessary to select the temperature according to the condition to which the given agricultural crop is accustomed.

Summer

Mostly in the summer, the greenhouse heater is turned off, but there are weather situations in which you have to turn on the device. For example, an early cold summer, when during the day the temperature warms up to +20 and above, and at night it is frosty. Or, when a rainy summer comes, precipitation falls in large quantities, the air temperature drops rapidly. In these cases, it is necessary to turn on the device.

Views

The main criterion is the buyer's personal preferences. Much depends on the requirements for the equipment. Let's consider several varieties.

Candlesticks

Candle heaters are used mainly in the spring and autumn, when the temperature changes from positive to negative (and vice versa). To minimize fluctuations in air and ground temperature, use this device. Thick candles are placed between the bushes and set on fire. This warms up the soil well and prevents the seedlings from freezing. However, such a device is designed for a small number of seedlings (no more than a few hundred bushes). Otherwise, the candles will not be able to warm the soil.

Candles are a small device and not always effective. Due to their small area of influence on the ambient temperature, they do not warm up the ground evenly enough.

Home

Summer residents use this method when the summer season comes. The homemade method allows you to maintain the night temperature. While on their site, they make a fire. Several bricks and a bucket of water are heated in it. When the work is finished, the bricks are placed in the greenhouse. The stones must be placed on wooden planks along with water.

The structure gives off its warmth all night, maintaining the desired temperature . The disadvantage of this design is that the degrees do not increase or decrease. The temperature returns to normal and lasts all night thanks to hot water and bricks. One of the advantages of this method is the fact that while heating the bricks, you can cook meat on the fire or baked potatoes.

With a large greenhouse area, this method with bricks and water will be ineffective.

Electric and gas

The specificity of this equipment is that the heaters convert energy into heat. Hence their big minus follows: a huge waste of energy. This type of heater is not suitable for a sick amount of agricultural products. Heats the device locally only those objects (seedlings, soil, air) that are in the immediate vicinity.

The disadvantage of these devices is that they do not ionize the air ., so it becomes dry and puts plants at risk of parasite infestation. Electric and gas heaters can cope with a large greenhouse if there are several of them. But then the big energy bill will multiply. Ultimately, this may lead to the purchase of another analogue.

Infrared

Agricultural professionals find that infrared equipment is the most important source of high-quality crops. Infrared heaters are characterized by low energy costs and high efficiency.

They have their own merits:

• They are characterized by high-quality heating, which extends throughout the greenhouse.
• They are characterized by providing the air with additional moisture.
• A disinfecting factor is noted, infrared rays kill a large number of microbes and incipient infections.
• They are distinguished by uniform heating without hypothermia, drought, temperature drop and overheating.
• A decrease in dust in the air and in the infrared heater itself has been noticed.

All these factors have a positive effect on the air temperature, as well as the growth of agricultural production. One of the main advantages of this type of heaters' heat is its easy installation. You can install such equipment on walls, racks or ceilings. A desirable and more correct solution is the ceiling option. Other advantages include noiselessness of the equipment, its compactness and high mobility. The heater can be installed correctly without the involvement of specialists.

The advantage of infrared equipment is the initial heating of the soil, not the air. This factor makes the equipment energy efficient. The air will not dry out, and the plants will not receive scalding heat. The infrared equipment has special temperature controls that are necessary for different crops in different growth phases.

Nuances of choice

The issue of installation is of particular importance, which should be given special attention. It depends on the correctness of work and yield. It is advisable to purchase a device that provides for the function of adjusting the temperature regime during the growth of agricultural products. It is good if you can set different temperatures for certain areas of the greenhouse in order to provide individual comfortable conditions for different types of crops.

It is undesirable to purchase a device without adjustment, otherwise the necessary conditions will be created for one culture, and for another they may not be suitable. Setting a single temperature setting for the entire greenhouse is not the right solution. Never buy equipment hand-held. First, as a rule, such products do not last long. Secondly, their quality is often poor.

Modern devices are significantly different from older ones . The main difference is the device screen. Enchanting plasma is installed in the new heaters, allowing them to cover up to 120 degrees. This allows all plants to provide the required amount of heat. When choosing a product for a film greenhouse, be guided by the fact that not every variety is suitable for it.

An interesting solution is the heating tape. In fact, it is an electrical device through which you can heat greenhouses. It is easy to operate, reliable and closed with a moisture-proof shell. It can be used in greenhouses where exotic crops are grown. It is a convenient and irreplaceable device.

Accounting for sizes

Let's take a look at which heater to choose. If you, for example, have a greenhouse measuring 6 x 3 meters, two heating devices are enough for you. Having bought two lamps with a capacity of 1, 2-1, 6 kilowatts, you can warm up the entire area of the greenhouse. When buying, it is important to pay attention to the size of the device. The ideal option under the conditions indicated above would be a heater with a length of 1, 6-1, 9 m and a dispersion angle of about 120 degrees. If you decide to increase the area, then you need to add new devices, or replace the entire heating.

If you have a non-standard greenhouse, its width is slightly wider, you can go for this trick . Hang the cutlery on both sides, not in the center. Thus, you will remove the gaps that the gasoline heater did not reach. Accordingly, the rest of the indicators can be reduced, and the number of heaters can be increased. When buying a tape, it is calculated for each m2. This will help make the heating correct and sufficient.
