A thermostat is a useful thing not only in an apartment or a country house, but also in the household. For example, in a greenhouse, the yield of which directly depends on the fine tuning of the microclimate inside the greenhouse. Often, even tenths of a degree can predetermine success on the site. Experienced gardeners are well aware of this point and often resort to the best thermostats in their greenhouses. We will tell you about which models are worthy of attention in 2022 in the KP rating.
Top 4 rating according to KP
1. Terneo RZ (average price 2100 rubles)
This thermostat is not specialized for greenhouses, but is in some demand among gardeners. Terneo RZ works only with infrared heating systems and is suitable for a greenhouse with an outlet. Of course, the heating must also be equipped with a plug. The latter is already included in the thermostat itself. The device has a remote air temperature sensor. The maximum temperature the RZ can operate at is 30°C. However, the device does not work with soil heating systems and has a rather modest IP20 moisture protection, which is not suitable for every greenhouse.
Advantages and disadvantages
2. DEVI Devireg 330 (average price 9000 rubles)
Under the same name, several models are hidden at once with a different range of heat regulation. For greenhouses, an option that can work with a temperature of 15 ° C – 30 ° C is more suitable. Devireg 330 is designed for installation in an electrical panel, which, perhaps, can be found in any modern garden plot, or rather, in a house. The kit comes with a sensor on a three-meter wire, but if this length is not enough (and if you pull it from the house, it is not enough), then you can buy a longer cable or come up with an extension cord yourself. Mechanical control – “twist” sets the desired temperature. Only works with electrical systems. Moisture protection here, although weak, but if you use the thermostat from the room, then this drawback is not critical.
Advantages and disadvantages
3. Caleo DW HOT-B (average price 1500 rubles)
A fairly simple model for regulating the temperature in a greenhouse from the Caleo brand. The thermostat itself is connected to a 220 V network or, simply put, plugged into a power outlet. The remote temperature sensor is stuck into the soil. DW HOT-B is able to control the temperature from -10°C to 50°C. Management is carried out using a mechanical ring. The error in determining the temperature is quite high – up to 3 degrees. And it’s not too good in a greenhouse. As well as the lack of moisture protection – high humidity can quickly disable the device.
Advantages and disadvantages
4. Heatline HLT-104 (average price 2700 rubles)
Another specialized model of a thermostat for a greenhouse that works with soil heating. The control here is rather confusing and consists of four keys – the summer resident will obviously have to study the instructions before using. Works with temperatures from 0 °C to 40 °C. According to the manufacturer, the body of the thermostat is hermetic and is not afraid of the moisture inherent in greenhouses.

How to choose a thermostat for a greenhouse
To ensure the normal functioning of a year-round greenhouse, it is necessary to maintain a clear temperature regime. It is not so simple, but a device such as a thermostat does. Mikhail Ippolitov, an amateur gardener who has been fond of growing vegetables in a greenhouse for many years, will tell about how to choose a thermostat for this, together with Healthy Food Near Me.
We observe the temperature regime
Probably 95% of the plants grown in greenhouses require temperatures between 16 and 25°C. The soil can be colder: 13 °C. And even if you deviate a degree from this “corridor”, the plants will begin to fade. But if you follow the entire technical process, then the harvest will not disappoint you.
Installation
A greenhouse is not a house, there is not always electricity there, and it is often difficult to install the device. Therefore, look for a device that will be most convenient to put in your greenhouse. In my opinion, the best thing is a thermostat that is designed for installation on a wall or a beam, which is why it is more convenient to work with it.
Power
The thermostat must be suitable for the power of the heating system that is used in your greenhouse. Better even with a margin – because greenhouses sometimes expand.
SENSORS
There are two fundamentally different options, as with greenhouse heating systems – for the soil and for air temperature. In the first variant, when the ground is heated, the temperature controller sensor also measures the temperature in it. If we heat the air, then the sensor is simply attached somewhere in the greenhouse, usually at a height of half a meter.
Ventilation machine
Together with heating and a thermostat, I advise you to use such a simple thing as an automatic ventilation machine. Roughly speaking, this is the automatic opening of a window or door upon reaching a certain temperature – this allows you to expel excess hot air. Such devices are inexpensive, and they use a mechanical thermostat.
