Bottom liner radiator: features of installation and

Heating

The supply to the radiator is of three types:

  • lateral unilateral;
  • cross;
  • located below.

Scheme of installation of heating devices

Each of the listed types has characteristic advantages and some disadvantages that need to be taken into account both when choosing heating equipment and when designing a heating system.

  • For example, the most common today is a side one-way connection. This is largely due to the location of the pipes in the apartments with a typical layout.
  • The cross method, as a rule, is used to connect devices with a large center distance or an increased number of sections.
  • Floor method is relevant in the event that you connect the heating devices to the pipes, conducted from below.

So, each of the previously listed methods is relevant in relation to a particular situation. Let us consider in more detail how the connection of radiators with the lower connection is performed.

Basic information

This is the look of aluminum radiators with bottom liner.

Modern floor radiators with bottom connection are relevant if the heating pipes are laid under the floor. I must say that today, when arranging new apartments and houses, in most cases hidden pipe laying is practiced, which means that heating devices are needed for this type of connection.

Important: Having chosen this method of installation of heating devices, it is necessary to use a special connection node for radiators with bottom connection. Such an approach to installation work will prevent the threat of flooding in the event of an accident and loss of airtight connections.

As already mentioned, each connection method has not only advantages, but also some disadvantages. In this case, the disadvantage is the reduction of energy efficiency of the battery by about 10%, in comparison with analogues connected in a different circuit.

However, the loss of efficiency can be compensated for by choosing the right heater. A wide assortment of batteries is presented, which differ in the type of materials used in the manufacture and in the degree of energy efficiency.

Therefore, in order to use an autonomous heating system with connecting batteries from below, it was not cold in the room, you should buy aluminum or metal devices that release heat more intensively.

What caused the need to use batteries with the connection below

Assembly for connecting pipes in assembled condition

As already mentioned, the main reason for the installation of bimetallic radiators with bottom connection is the location of the pipes under the floor. But it turns out this is not the only reason.

The attachment, performed below, looks more aesthetically pleasing than the side or cross. The fact is that the interior, designed in this way, looks much neater and more harmonious.

Connecting to the bottom is more practical, since it can be done by hand using a special node or directly. If a special assembly is used, the battery can be disconnected from the system without the need for draining water. This is more than relevant if there was a need to repair one of the devices with a functioning system.

The need to connect from the bottom can be caused by the design features of the battery itself. For example, some tubular or panel models in the stock configuration have inlets located not at the sides, but at the bottom.

Important: The standard fixtures for the lower liner are equipped with heating devices made of steel. Bimetallic and aluminum batteries with the standard assembly required for connection to the pipes from below are, to a large extent, not completed. As a result, this node must be purchased separately and fastened to the lower side branches provided as standard.

Types of heaters

An example of how bottom-mounted bimetallic radiators can be installed.

In the standard configuration, not all types of batteries are equipped with everything necessary for a lower connection. If you choose heaters that are equipped from the factory with a unit for connecting pipes laid in the floor, it's time to pay attention to steel radiators with a lower supply pipe.

This category of heaters is offered for sale by the following modifications:

  1. Panel batteries, which, in accordance with the configuration, are divided into the following models:
  • smooth;
  • profile;
  • hygienic.

Profile models are widely used in everyday life. These devices are easy to recognize by the box-shaped casing with stamping on the front side, made in the form of vertical stripes. This modification is popular because its price is the most affordable, and in addition, decorative stamping gives the device a special appeal.

Smooth and hygienic models are easy to identify by the lack of stamping. Such heaters are rarely used in everyday life, as they are mainly installed in medical institutions, public buildings, etc.

Characteristic features of these batteries are ease of care, as they are easy to clean from dust and launder from various contaminants.

  1. Tubular batteries, as well as panel, are made of steel, but they look more attractive. Tubes from which the heating device is assembled are combined sections through which coolant circulates.

Such models in standard configuration can be equipped with fittings for connection to pipes laid in the floor or in the lower part of the walls.

How can I bring the pipe bottom

Aluminum and bimetallic heating radiators with a bottom connection in the standard configuration are rare, and therefore may require the acquisition of a special node through which the connection is made.

In this case, please note that the bottom connection can be of the following types:

  • Unilateral connection, at which both pipes join, on the one hand. This is the most popular solution as the pipes for flow and return flow with concealed liner are arranged with a gap of 10-20 cm. The advantage of this type of connection is the accuracy of the whole structure.
  • Versatile joining involves connecting pipes on opposite sides of the battery. Such a solution is often found and is often dictated by the configuration features of the heating system.

Features of the installation work

The installation of heating devices and, for example, the installation of bimetallic radiators with side connections do not differ much from each other.

  • The battery is installed on special brackets, which are selected in accordance with the type of radiator.
  • When placing the battery, make sure that the gap from the bottom does not exceed 20 cm, but not less than 10 cm. If the gap is smaller than necessary, it will be difficult to clean. If the gap is larger than necessary, the formation of cold areas is possible, which will adversely affect air convection.
  • Fittings are screwed using a fum tape as a seal.

Conclusion

So, we have considered what is the instruction of connecting the heaters to the lower supply. There are questions that need clarification? You will find more useful information by watching the video in this article.
