Features of bimetallic radiators with bottom connection

Radiators can be connected to heating systems in several ways, one-way, diagonal and bottom connections are currently used. Their differences lie in how exactly the pipes for supplying and discharging water will be located, as well as how strong the heat transfer will be.

As the name implies, bimetallic heating radiators are composed of two types of metals. Their production began in Europe more than half a century ago, and since then these heating devices have gained immense popularity in the market and have been praised by consumers. Such batteries can be mounted in any heating system.Inside, radiators are made of stainless steel, sometimes copper is used.

The choice of manufacturers was stopped on these metals due to the fact that they are well tolerated by the aggressive environment in which they are located when hot liquid passes through them. Their pipes are both vertical and horizontal, which allows the coolant to circulate freely.

The outer part is a section made from aluminum and having fins. Aluminum is used because it has good thermal conductivity, it heats up in a short period of time and gives off heat perfectly. The method of connecting the external and internal parts of the sections is spot welding or casting. After all the structural elements are ready, they come together and the sections form a one-piece radiator.

Consumer demand determines how well the product will be sold on the market. Bimetallic batteries have the highest price in comparison with other radiators, due to this aluminum products or steel have become more popular, however, the quality and reliability in the case of them leave much to be desired.

The coolant enters the radiator in small volumes. This is due to the fact that the channels are quite narrow. However, this situation is an advantage, since the case heats up as quickly as possible, and with the help of thermostats it is possible to adjust the temperature parameters.

According to experts, bimetallic heaters with lower wiring are considered the most successful solution, as in this case, the heating of the room occurs both due to radiation, and due to convection. These moments compensate for the reduced heat transfer of this type of battery.

As mentioned above, there are several ways to connect radiators. Currently, consumers are interested in precisely the lower wiring. It allows you to hide the heating pipes under the floor so that they are visually invisible. This is a win-win option when arranging the interior of the rooms, as these elements will be hidden from prying eyes, and the microclimate in the room will not be affected.

When choosing heating radiators for the home, consumers are often lost, as these products are presented on the market in a huge range. Cast iron batteries are becoming a thing of the past, giving way to more modern, high-quality and aesthetically attractive models of aluminum, steel and bimetals. Bimetallic radiators have a special unit that is responsible for the lower supply pipe of the heating pipes.

The installation process is not difficult, and such batteries are very convenient to use due to the fact that when the heating is switched off seasonally, there is no need to drain water. Heat transfer from such radiators is quite good, especially if the lower coolant flow is organized. The product design is responsible for this process.

The heat carrier heats the lower elements, and the upper, in addition to hot water, are affected by hot air flows. Due to the steel core, the strength of the radiator is ensured, it becomes resistant to water entering under high pressure, as well as to its increased passing speed. The steel in the composition is resistant to corrosion and high water hardness.And the maximum heat output is due to the aluminum surface of the radiator.

In convective heating, aluminum is the most advantageous option, even in comparison with cast iron, since the intensity of its heat transfer reaches 60 percent.

The system of fins in such batteries is quite complicated, it is possible to swap them, and also add additional elements if necessary. Bimetallic radiators are easy to install due to the fact that the pipes are connected directly. This means that there are no bends that impede the flow of hot water, so the elements are heated as quickly as possible. Another advantage can be considered a low price for carrying out installation work with such devices.

The large number of advantages of installing bimetallic radiators with lower wiring does not mean that this process has no disadvantages. Among them, first of all, it should be noted the high price category of such products. However, this minus covers long battery life. Violations during operation may also face some unpleasant moments.At the end of the heating season, it is not necessary to drain water from the radiators, which may threaten the formation of corrosive processes of the steel core.

Due to the fact that the heating pipes are hidden under the floor covering, they can cause problems with access to them. Dismantling the floor is a time consuming and costly process, however, in some cases you cannot do without it. Reducing heat transfer at the lower connection of pipes can be avoided if you correctly and correctly approach the choice of equipment.

The type of bottom liner depends on the characteristics of radiators. Three types of products are suitable for this process:

• bimetallic products have sections with convection elements, they can be connected in different ways at the expense of 4 connection points for heating pipes;
• Panel batteries can have a smooth and grooved structure. Upper, as well as diagonal, connection methods in this case are impossible;
• Batteries with steel pipes give off excellent heat and can be used whenone-way connection to the heating system.

Bottom liner can be both one-sided and versatile. In the first case, all heating pipes are on one side of the radiator, the coolant is fed from the top, and drained from the bottom. In some models it is possible to connect both pipes from below. With a versatile connection, the supply of hot water and its withdrawal are made from different sides. The coolant is able to circulate in different directions. When the heating system is individual, this option becomes the optimal solution.
