The design of tubular radiators makes them one of the most popular and in demand on the market.
They are characterized by high operating efficiency, corrosion resistance and an aesthetic appearance that does not spoil the overall interior of the room. Such radiators consist of an upper and lower collector, which are connected by jumper tubes.
All radiator elements are connected using laser welding.
Due to this, the seams look as neat and invisible as possible, and the radiator successfully withstands the increased pressure in the system.
Since radiators are designed to provide warmth throughout the entire house, they should be selected as carefully as possible.
A short list of criteria given in the article will help you do this, as well as a rating of the best tubular heating radiators according to the 2021-2022 version in price/quality ratio.

How to choose tubular radiators?
Tubular radiators differ in size, cost and some other technical characteristics.
There are several important selection parameters:
- Location . Radiators are available vertical and horizontal. The selection according to this criterion is purely individual and depends on the user’s preferences. In addition, some models have an original shape, and perform not only a heating function, but also serve as an original addition to the interior.
- Power . Although each radiator has a certain capacity, the design of tubular models allows registers to be added to the radiator, increasing their power.
- Coolant volume . One of the most important criteria for choosing a tubular radiator. It depends on whether the radiator has enough power to heat the room. In addition, the volume of coolant in the new battery must fully correspond to the volume of the old one.
Also, when choosing a radiator, pay attention to its size, because it must fit harmoniously into the interior of the room.

Which company should you choose?
The manufacturer of the tubular radiator also plays an important role, because the equipment must be adapted to local climatic conditions. That is why experts recommend giving preference to domestic products.
When choosing a foreign-made radiator, you should make sure that it can be connected to domestic heating systems.
Among the huge variety of tubular radiators on the market, products from the brands KZTO, Arbonia, Zehnder, Irsap and Purmo were recognized as the highest quality.
We have selected the best models of these brands that received the most positive reviews in 2021-2022.
How to choose and what to pay attention to
Tubular radiators vary in their technical characteristics, sizes, manufacturers and many other parameters.
In order to choose the best option, you need to consider several factors:
- The area of the heated room;
- Radiator pipe diameter;
- Heating radiator installation location;
- Methods of connection to the heating system.
Tubular radiators can be vertical, horizontal, can have an original unusual shape and, together with the function of heating the room, can be part of the design.
Tubular radiators are made in heights from 0.3 m to 3 m. Tall vertical radiators can be installed as a partition in a room, and also used as a bar counter, column, or bench.
The radiator section can consist of 1 - 6 tubes, which allows increasing thermal power by increasing the heating surface area and a larger volume of coolant in the radiator pipes.
Manufacturers warn that it is better to install such heating devices in individual houses or low-rise buildings, up to 5 floors.
In high-rise buildings, sudden pressure surges exceeding 10 atm can occur, which can cause radiator leaks.
Tubular radiators are often used in medical and children's institutions due to their high hygienic properties, ease of processing and safety (no sharp corners).
