Most city apartments have heating batteries, where the type of connection to the pipeline is standard (side). This method is characterized in that the coolant enters the upper part of the pipe, and exits from the same side along the lower. However, in private households it is not always possible to carry out such wiring. That is why people living in private houses prefer to install heating radiators with lower eyeliner. Let's look at how to connect these batteries, what advantages they have.
Functions
The winding and unaesthetic pipes of the heating system are not the best decoration in the interiors. Designers come up with sophisticated ways to hide standard cast-iron batteries. It should be noted that this is not always the case. This problem is solved more efficiently if you use heaters with a lower coolant connection. Then all the pipes will be located not in sight, but under the top floor.
The modern market offers a huge selection of this equipment. So,
bimetal heating
radiators with bottom connection can be considered an ideal choice, installation and connection of which can be done by yourself. The connection operation can be performed either directly directly or using a special unit. The latter will greatly facilitate further operation and maintenance. The main convenience is that when the radiator is disconnected from the main, there is no need to drain the water.
In aluminum, as well as in cast-iron batteries, there is no possibility of creating a lower liner. But steel panel or tubular radiators are quite suitable for organizing the connection in this way. Next, we will look at the installation methods.
Connection Methods
Heating radiators with bottom connection can be connected in two ways. So, distinguish one-sided and versatile installation. What features do these methods have?
In the first case, the pipe outlets will be on one side. Heated coolant will pass through the upper radiator plug. The removal of the cooled liquid goes through the lower plug.
In the second case, the coolant is supplied from one of the edges. Cold is displayed on the other hand. Experts recommend using this method where autonomous heating systems are installed. The plus is that the coolant supply can be arranged as you like. Also, the length of the pipes will be much shorter. This will save time and money that will be required to conduct this operation.
Types of radiators
There are three types of radiators with bottom connection. In what situations will they be beneficial? Consider below.
We can distinguish a bimetallic sectional radiator equipped with conventional plates. This heater is universal - it has as many as 4 points for connecting to the pipeline. For example, products from Kermi can be connected in various ways, including with a lower eyeliner. Heat losses in the worst case will be no more than 15 percent. This problem can be easily solved by installing and adjusting thermostats.
Also corrugated as well as smooth radiators with lower flow are distinguished. They do not have the ability to connect otherwise.
You can use a steel tubular battery. According to experts, their effectiveness is very high. Steel and its alloys have the highest heat transfer among all the options on the market. From this group,
vertical heating radiators with bottom connection are distinguished - they are the most expensive. Their height can reach 2.5 meters. These are Italian and German products. They are connected one way. The elements of the supply and exit of the coolant are nearby.
The main pros and cons
With the installation of such heating equipment in the premises, harmony can be achieved, as well as symmetry in the lines. The pipeline hidden under the floor will not attract attention and will not spoil the design.
At the same time, radiators with lower connections have disadvantages. As already noted above, due to aesthetic tasks, the pipeline is mounted in the floor or hidden from view under the baseboard. If even the most minor accident occurs, the repair is fraught with serious difficulties.
In order to get to the emergency site on the pipeline, it will be necessary to dismantle the flooring. This process will take some time. This will entail additional costs, since in addition to repairing or replacing damaged pipes, the floor will have to be restored.
Experts also argue that heating radiators with bottom connection do not have a high level of heat transfer. If we talk about the latter, then in the first place are traditional radiators with a side connection method. They are most often chosen for installation in private households and old apartment buildings. Due to the fact that the supply pipe and outflow are located on one side, the radiator warms up as much as possible. Ineffective lower method of supplying coolant in the case of using multi-section batteries. These appliances may not always warm up completely. This problem is solved using special duct extenders. Most often, steel radiators with bottom connection are chosen by homeowners in the private sector, where autonomous heating systems are installed.
Mounting
In the process of installing these devices, it is necessary to take into account some rules and work according to a certain algorithm. This will eliminate possible errors.
First of all, you need to take care of access to the place where the bottom coolant connection is connected to the battery. The distance from the floor to the bottom of the radiator must be at least 7 centimeters. You also need to withstand at least 10 centimeters from the windowsill to the top of the radiator. Due to the exposure of these distances, the air convention will be most correct. The radiator will heat not only flower pots, but the whole room. Plus, you can always get to the battery if necessary. From the wall to the radiator should be at least 2 centimeters. Specialists advise you to take these parameters into account when installing radiators with a bottom connection.
The place where the radiator will be installed should be selected before installation work. This is necessary to approximately represent places for fasteners. It is better to install without removing the packaging from the radiator, so as not to damage it. This is true for all models. After the place is determined, it is necessary to develop a scheme for installing heating radiators with bottom connection. The battery can be equipped with a special thermostatic insert for mounting the thermostat. The latter will allow you to adjust the heating.
Installation Instructions
First of all, the battery is installed on a special stand, and the building level is laid on top of it. The device must be set perfectly evenly. When the radiator is exposed, the fasteners are driven in. But at the same time, the number of battery sections must be taken into account. If there are five, then there are two fasteners. If seven or more, then three mounts. Next, holes for fasteners are punched. And then a battery is hung on the fasteners.
Connection to the pipeline is carried out using special L-shaped tubes. They must be firmly fixed and carefully filled with foam. However, this should be done only after the final installation and crimping of the system.
Expert Advice
During installation, you should pay attention to those places where there are pipes for supplying coolant and its removal. Sometimes they are located on different sides. In this case, you need to look at the marking - it is important not to mix up the supply and outlet pipes. If connection points are only on one side, it is important to be careful when connecting. The heat transfer in the case of the bottom connection is not very effective, and if the radiator is not connected correctly, the quality of heating will drop significantly.
Manufacturers and prices
The most popular companies that produce quality products are the German company Kermi, as well as the Finnish brand Purmo. In the CIS there are also companies that produce quality products. Good models are produced in Austria. Prices range from 4.5 to 10 thousand rubles. The cost of products is affected not only by the brand, but also by the material of the radiator, its heating area, the number of sections and the presence / absence of a thermostat.
Conclusion
I must say that radiators of this type are very functional and do not differ in technical characteristics from other types of batteries. Also, they do not have any significant advantages over other types of heating radiators. Such equipment is chosen only when the interior requires complete concealment from the view of the pipes of the heating system through which the coolant is supplied. And if the design does not require it, it is better to give preference to batteries with traditional coolant supply. Otherwise, in the event of an accident, you will have to redo the entire flooring. Also, installing radiators with a bottom connection requires more time and effort.
