Heating radiators are devices through which thermal energy from a boiler plant is transferred to the room. The efficiency of heat transfer is affected by the surface area of the radiator and its configuration, through which convective flows are created and heat is evenly distributed throughout the room.
The problem is that a classic radiator is a bulky and unpresentable structure, usually located under window openings. And what to do in the case of the popular panoramic glazing, if there is no possibility of installing an underfloor heating system? In this case, there is one proven method, which is to use vertical radiators for a private house.
The types and design features of these devices will be discussed in this publication.
Dealing with definitions
Many will say that almost all batteries can be considered vertical. And they will be right. Vertical radiators differ from conventional ones in the predominance of the height of the heater over the width. For a better understanding, below are photos of vertical radiators and classic radiators.
Important! There are no dimensions or exact proportions that classify this equipment. The device of vertical radiators does not differ from the classic ones. The difference is only in external perception and some performance characteristics, which determine the positive and negative aspects of their use.
Advantages and disadvantages
The main idea behind the production of vertical radiators is the creation of new radiators, which would not only fulfill their main function, but also be able to decorate the room, become part of the interior design solution. From a purely functional point of view, vertical radiators have the following advantages:
- The minimum occupied space on the wall, with the maximum possible thermal power for its dimensions.
- The spread of IR radiation at the level of an adult’s height, which makes it more comfortable to stay indoors.
- The possibility of installation in any interior due to the variety of appearance, designs and configurations.
On the design and some design features, you should stop and consider the options in more detail.
The dimensions of these heating devices prompted designers and designers to come up with an idea that allows radiators to perform additional functions.
Changing the configuration from the classic rectangular one allows the use of a vertical radiator as furniture elements, interior partitions, decorative items.
When choosing batteries for a private house, one should not forget about the shortcomings of vertical models, which include:
- Uneven heating of the entire volume of the room due to design features. In the upper part of the room, a “thermal cushion” is created, which reduces the speed of movement of convective flows.
- The characteristic shape of the products often causes air in the system.
- The massiveness of vertical batteries requires the use of more serious mounts.
- High cost, which, depending on the model, is many times higher than classic batteries of a similar design.
According to experts, the main problem with the use of vertical radiators is their connection scheme. Most models use a bottom connection, and, as you know, it is the diagonal movement of the coolant through the heater, from the position of heat exchange, that is the most effective.
As mentioned above, the design of vertical batteries, as well as the materials from which they are made, do not differ from classic radiator models.
Types of vertical radiators
All batteries of this design can be:
- Aluminum. They are characterized by good heat dissipation and a wide range of models. They are not recommended for installation in central heating systems due to the ability to withstand relatively low operating pressure (up to 6 kg / cm2).
- Cast iron. Corrosion resistant, withstand (depending on model) pressure up to 18 kg/cm2.Can be used in centralized and autonomous heating systems. Disadvantages: poor resistance to mechanical damage, large mass.
- Bimetallic. They consist of two types of metal: the internal structure is made of steel; aluminum outer shell. They are characterized by high heat transfer, corrosion resistance and high pressure resistance (up to 40 kg/cm2).2). The disadvantage is the high cost.
- Steel. This type of radiators, according to their design, can be divided into:
The first type of batteries consists of separate sections, which are mounted to each other using threaded connections. You can create a radiator of the required thermal power and width. The height of the sections can reach 2 meters.
Panel-type radiators are steel sheets fixed at a certain distance from each other. Convectors are provided by the manufacturer inside the panel. Steel panel batteries can be installed both in autonomous and centralized heating systems, as they have a sufficient margin of safety and can withstand pressure up to 16 atmospheres.
These products have a number of advantages and have some disadvantages, namely:
- They heat up quickly, but practically cannot accumulate heat.
- They are quite decorative and take up little space, but they have all the connection problems inherent in vertical models (only the bottom one).
- For normal operation, they do not require a large volume of coolant, but they do not tolerate sudden pressure surges in the heating system.
Tubular radiators are a welded non-separable structure of vertical pipes connected to each other in the lower and upper parts by horizontal collectors. Vertical pipes, depending on the model. They may be in one or more rows.
Most domestic manufacturers have foreseen possible pressure surges in the system and use a steel pipe 2 mm thick for the manufacture of vertical tubular radiators, due to which these products can withstand pressure up to 20 atmospheres.
- Reliability and durability.
- Corrosion resistance due to the polymer coating of the inside of the pipes.
- Resistant to pressure drops.
- The most varied design.
Among the shortcomings, experts note mediocre heat transfer.
Tip: in order to answer the question of how to choose heating batteries for a private house, you should consider such aspects as the design of radiators, their dimensions, weight and required thermal power. We should not forget about the possibility of working one or another model with a certain coolant, as well as the resistance of heating devices to pressure drops. Experts recommend that the choice of the type of vertical radiators and the correct calculation of power be entrusted to professionals.
