What gives each house coziness and comfort? Of course - a warm hearth! To keep warm, whether it’s a house or an apartment, various heating devices have been developed over the years, such as heating elements (tubular electric heaters), heat guns, and even attempts have been made to improve radiator batteries. Often on cold winter evenings, even a fireplace is not able to maintain enough heat in the house.
The right choice of thermal curtain
To date, the most advanced solution in the field of heat input is the thermal curtain. It helps to keep warm in any premises, even in non-residential facilities, such as offices, shops and industrial enterprises.
The size
Thermal curtain - an electric air heater installed above the doorway. Therefore, an important factor when choosing this device is the size of a particular opening, or rather, its length. The line of models includes a variety of sizes, starting from 70 cm, ending with 2-meter curtains. If the length of the opening is much longer, then paired curtains are installed in the maximum proximity to each other, which prevents the effect of "ajar windows".
Therefore, independently choosing a device, you need to remember about 2 important nuances:
- the model of the device should be longer in length than the width of the opening;
- if the dimensions of the opening significantly exceed the length of all existing models of curtains, then 2 models are purchased for the length of the opening, and they should be installed as close as possible so as not to create a source of "draft".
Performance
A wide range of curtains also implies various performance, that is, the flow rate of heated air. The larger the dimensions of the door, gate or opening in the production, and the higher the curtain will be located, the greater should be its performance.
For a standard doorway, whose dimensions, as a rule, are 1m * 2m, it is necessary to choose models with a capacity of at least 900 cubic meters per hour. In this case, the force of the supplied warm air will be equal to 8-9 and 2-2.5 m / s at the top and bottom of the opening, respectively. This will block the entire doorway with a warm stream.
Type of heating element
After the choice of the necessary type of model has been made, it is worth learning about the difference in the type of the heating element itself.
The function of the device is to separate the warm air indoors, from the cold air outside. And even a stream of temperature-neutral air copes with this perfectly. His strength goes from top to bottom, to the floor, which does not allow cold air, for example, from the street.
But if the curtain is installed in a store where doors are constantly opening, then in order to prevent a decrease in room temperature, it is better to use a stream of hot air. Therefore, you need to know which heating element will stand in the selected model, and how it works.
All models are divided into only 2 types of heating device:
- Spiral
- TEN
It distinguishes between both types: model price and service life.
The spiral heater is a regular spiral of wire, like a boiler. Therefore, it is not expensive in cost, but requires large amounts of electricity. And according to the term of operation - not very durable.
TEN is the opposite of a spiral heater. It is a steel tube with quartz sand and a graphite core inside. Therefore, it is absolutely safe and will last a long time, compensating at times its high cost.
Coolant type
Thermal veils are developed under various energy sources, therefore they are divided into 3 types:
- Gas
- Water
- Electric
For large industrial premises, gas curtains are the best option. They are safe sources of heat, and have the highest efficiency (almost 100%). However, among all models, they are the most expensive.
What thermal curtain is better to install over the front door
Watercrafts also have enhanced performance. But their installation is complicated by the fact that there should be a water supply system nearby. If there are no interruptions with this energy source and it is necessary to maintain heat of a sufficiently large space, then this type of curtain will be a good help in saving electric energy.
For small apartment and office doorways, windows, entrance doors, not only in apartments, but also at home, the best option would be an electric thermal curtain. If the performance and dimensions of the model are correctly selected, and the installation is made by professionals, then its operation will not be any problems.
Selection by parameters
You can choose a device with the help of a specialist, or independently. But it is necessary to take into account all the parameters of the future curtain and its compliance with the dimensions of the doorway and the room that it will "protect" from the cold.
Despite the fact that more often it is horizontal curtains that can be found, there are other types of installation. Of them distinguish:
- Horizontal
- Vertical
- Universal
Horizontal and vertical curtains must be installed in accordance with the requirements of the manufacturer. Horizontal ones are often bulky, and must be mounted on brackets using threaded rods. Vertical - should be installed on the side of the doorway, and at the same time for proper operation should also occupy almost its entire height - not less than ¾!
The most popular model design of the thermal curtain is universal! This model allows mounting both horizontally above the front door or window, and vertically from one or two sides of the door.
For example, you need to choose a thermal curtain for a store that is small in parameters and well-heated.
To begin with, the dimensions of the doorway are determined: height and width. Suppose they are 2.30 and 1 meter, respectively. There must be a place above the front door to properly fix the device, and in the future nothing prevented its stable operation.
The model corresponding to these dimensions should be at least 1 meter long, and the performance force should provide a range of warm air flow of at least 2.5 meters. Power model - 6-9 kW. But since a given room provides a constant door opening, it is better to choose a model of 9 kW. Choosing from the types of veils, it is necessary to take into account which energy source is nearby, but in this case it is predetermined - electricity. Installation of the model can be either horizontal or vertical, if the dimensions of the model do not correspond to the space above the doorway. Also, as an electric heater, it is worth giving preference to TENU. Although its price is high, but the service life and degree of safety are on the level!
The latest nuance in choosing a curtain will be its design and control methods. But here the buyer plays the main role!
In any case, one should not neglect the help of specialists in trading floors, who will not only select the necessary model of the thermal curtain, but also talk about all types of models and the functionality of each of them.
