Radiators with bottom supply are bimetallic

Selecting the appropriate heating system is essential for maintaining the warmth and comfort of our homes. Radiators with bottom supplies are one common option that many homeowners take into consideration. These radiators are renowned for their dependability and provide effective heat distribution.

A particular kind of bottom supply radiator called a bimetallic radiator combines two distinct metals to improve longevity and performance. These radiators are made to withstand higher pressures and temperatures by combining different metals, which makes them an enduring choice for heating your house.

Bimetallic radiators are not only incredibly strong, but they also produce a lot of heat, so even in the coldest months, your house will stay warm and comfortable. Your home will be comfortable and your energy costs may go down thanks to their effective heat transfer capabilities.

Bottom-supply bimetallic radiators are a viable option to consider when installing or renovating your home’s heating system. Their exceptional performance, longevity, and efficiency make them a popular option for many homeowners seeking to enhance the insulation and heating of their homes.

Rules for installing bimetallic radiators with bottom connection

To guarantee an efficient coolant supply and reduce power losses, each radiator connection scheme should be chosen separately. Bottom-connection bimetallic radiators are a fairly common configuration for heating systems because they provide an attractive appearance for the interior. The pipeline either follows the plinth or is completely hidden, which creates harmony and aesthetic appeal.

Features of the bottom scheme

The bimetallic heating device is made with two collectors on each side, which are situated in the corners of the. Every unit has the option to be linked to a heating system pipe. The supply and return pipes of a bimetallic radiator are connected to the bottom manifolds using the bottom connection pipe layout technique. A plug and a Maevsky tap are used to close the upper collectors to allow air drainage.

Rice. 1 The appliance’s one-sided connection

There are various ways to implement the connection scheme for bimetallic heating radiators:

• One-way scheme of bottom pipe connection (Fig. 1) is when the inlet and outlet of the coolant are next to each other, on the same side. Hot coolant circulates through the upper plug in the bimetallic radiator and is discharged through the lower plug already cold;
• Versatile scheme of the bottom supply (Fig. 2).2) – in this connection, the coolant inlet is on one side and the cooled coolant outlet is on the opposite side.

The bimetallic radiator model, which needs to be connected from below, should be selected based on the room’s size. It might be necessary to hang multiple panels because it cannot be extended like a sectional model.

Advantages and disadvantages

The following are some benefits of the bimetallic radiator’s bottom connection:

• Aesthetic appearance. With this connection scheme it is easier to hide the pipes. For example, this can be done by concealing them under the floor, in the wall, or under the skirting board.
• Simplicity of installation. The pipes are connected directly, with few bends, turns, etc.д. Thus, the heat transfer medium flows in without significant obstacles.
• The price of the lower connection scheme is less than the others;
• The bottom connection system is more stable, i.e. it is difficult to unbalance it.

Cons of using a bottom connection:

• If the pipes are run under the floor for aesthetics, it will be very difficult to fix leaks. It will be necessary to dismantle the floor. This system is not connected in an apartment building, as there is a central heating system there.
• The level of heat output of radiators with the lower supply scheme is somewhat less than with other connections.

Regarding the low heat output, bimetallic radiators’ channel design provides an explanation. The battery’s lower part heats up very quickly as hot coolant is fed into it. Convection causes heat to build up on the battery’s top. Air will therefore continuously gather at the top of the radiator, where it may not be completely heated.

This also holds true in the case where water and antifreeze make up the heat transfer medium (Fig. 4). Water rises to the top, but antifreeze always floats at the bottom because it is heavier than water. Consequently, the device’s coolant circulation is disrupted by the bottom connection scheme. Low heat transfer and inefficiency of the lower connection scheme result from this.

How should a bimetallic radiator be connected correctly? Of course, there are certain knowledge and skills required for this. There are certain guidelines that must be followed when connecting a bimetallic heating device. It should be mentioned that connecting the lower pipe pattern at the start of repair work is preferable. The pipes go in the wall or beneath the floor because this connection is purely decorative.

All measurements must be carefully followed. For instance, there should be a minimum of 15 centimeters between the floor and the radiator and a minimum of 2 centimeters between the device and the wall.

Next, precisely marking out the locations for the brackets requires the use of a level. Installing the radiator on a stand with a level on top is preferable because you can ensure that all measurements are taken accurately. Generally speaking, the bimetallic heating device comes with brackets. The quantity of these fasteners ought to be in line with the device’s dimensions.

It’s critical to distinguish between the supply and return pipes when connecting the pipes. The radiator has the proper markings, so you must carefully read all of the inscriptions to avoid this. The heat output of the bimetallic heating radiator is drastically decreased when connected incorrectly, by as much as 60%. Naturally, it depends on the type of heating appliance.

The L-shaped lower tubes need to be strengthened, but only after the system has been thoroughly inspected. Use mounting foam to help you with it, generally speaking.

Bimetallic radiators should be installed and connected in protective packaging. This is crucial since damaging the paint on the radiator could start an irreversible process. The paint will keep swelling due to the damage. In the event that this occurs, you will need to treat the scratch with a specific enamel-based paint. Prior to connecting, the packaging needs to be on the radiator.

It is recommended to clarify this with a store consultant, but the radiator should come with all accessories, plugs, and taps. In particular, it plugs into the other collector and is a Maevsky faucet. To avoid overtightening the connection and damaging the Maevsky valve, it is important to install it correctly using a torque wrench. Never use anything to clean the joints because doing so could cause leaks to appear when the system is turned on.

We are able to identify these well-known manufacturers:

• Kermi (Germany);
• PURMO (Finland);
• Rifar (Russia)
• Euroterm (Turkey);
• Regulus (Poland).

Verify the products’ certification before purchasing a bimetallic radiator.

Installation of radiators with your own hands

These days, bimetallic radiators are widely utilized in residential and apartment heating systems. They are quite popular in the home heating industry because they have several significant advantages over cast iron and aluminum units.

When it comes to benefits, bimetallic batteries have the following characteristics:

• High heat output.
• High corrosion resistance compared to aluminum products.
• Good working pressure.
• High inertia.
• Small mass.
• Attractive appearance.

Bimetallic radiator installation is a tedious procedure that takes a lot of time and energy. However, you can complete this task with your hands if you are cautious, understand all the nuances, and carry out every operation correctly.

It is important to keep in mind that the effectiveness of the heating system is dependent on how well the strapping is manufactured.

Disassembling outdated batteries

In the event that you are referring to the manual replacement of outdated radiators rather than the installation of a new heating system, we will begin by disassembling the outdated batteries. The procedure appears as follows, step by step:

• It is necessary to stop the system, wait for it to cool down and drain the coolant.
• With a bolgar we cut off the old radiators on the supply line between the threaded connection and the unit itself.
• Holding the pipe with one pipe wrench, unscrew the unwanted piece of pipe with the second one. If the connection does not yield, it must be heated – due to thermal expansion of the thread will be able to turn the threads.
• After unscrewing the unwanted pieces of pipe, clean the threads on the supply pipe and inspect them for damage. If any are found – cut it off with a bolgar and cut a new one with a die.
• Unwanted radiator is removed from the fasteners. Do not prematurely remove the fasteners themselves – they may be useful for fixing new bimetallic radiators to the wall.

Estimating bimetallic heating systems

It is essential to accurately calculate the battery capacity in order to guarantee effective room heating. The size, or the number of sections, determines this.

Determine how much power the radiators will need based on the room’s volume and the heating standards. Given that a bimetallic radiator’s single section has a power of roughly 180 W, we gather the required number of sections to provide the needed capacity.

We determine whether the product can be installed in our room using the measured dimensions. The following elements need to be considered:

• Heating radiators are installed under the window openings – in this way we create a heat curtain for cold air coming from the window.
• Strapping with your own hands is carried out in such a way that it is possible to perform service and repair of the unit without stopping the heating system, for this purpose, a system of bypasses is used.
• The distance from the upper edge of the battery to the window sill should be from 5 to 10 cm.
• The distance from the floor to the bottom edge should be about 15 cm.
• Installation is carried out in such a way that the unit is located on the wall along the center line of the window.
• Strapping of new radiators is most convenient with polypropylene. If it is a question of replacing radiators, it is possible to use the old piping, provided that it is in good condition.
• The piping is made using a system of bypasses, regulating valves and Maevsky taps.

Methods for connecting and wiring bimetallic radiators

You must be aware of the various methods for piping installation if you plan to install bimetallic batteries yourself.

Two varieties of heating systems exist:

• Single-pipe – the coolant moves along one pipe from the boiler through all heating devices connected in series. The disadvantage of this scheme is that to the last unit the liquid comes to the last unit already noticeably cooled down. Therefore, in order to equalize the temperature in the rooms, the last in the chain of devices must be increased.
• Two-pipe – the coolant moves through the pipe, to which the heating devices are connected in parallel. The cooled liquid is returned to the boiler through another pipe. Such a system provides even heating of all the batteries, but it is much more expensive and complicated.

The following diagrams can be used to guide the process of connecting to the system:

• One-sided – the device is connected through the upper and lower spigots on one side.
• Bottom – the device is connected through the right and left bottom sockets. This scheme is used if we hide the pipes in the floor.
• Diagonal – the device is connected through the upper pipe on one side and through the lower pipe on the other side.

Bimetallic radiator installation done by hand

We can start installation after the old radiators are taken apart, the new radiators’ dimensions are determined, and they are put together. The radiators are easily affixed to the wall due to their small mass. The steps in the process are as follows:

• Place the unit on the wall and mark the locations of the brackets on the wall with a pencil.
• Place the unit on the floor and fix the brackets to the wall using wall plugs at the marked locations.
• Fix the unit to the wall.
• Cut into the riser tee and lead the supply line to the place of installation of the battery.
• We make the connection using a bypass system and regulating valves. Put a Maevsky faucet at the blind point to get rid of air bubbles. All threaded connections must be made using gaskets and a torque wrench to control the tightening torque.
• Once the piping is complete, start the system and make sure that there are no leaks and that the units are heated evenly. If everything works well, the work can be considered complete.

Installing bimetallic radiators by hand is a labor-intensive and intricate process. But it’s easily accessible to someone who works hard and keeps things tidy. Your bimetallic products will appropriately heat the house, providing you and your loved ones with coziness and comfort, provided all requirements are met, all subtleties are considered, and all operations are carried out diligently and conscientiously.

Selecting bottom-supply bimetallic radiators can significantly improve your home’s insulation and heating efficiency. These radiators are strong and efficient because they combine the strength of steel with the heat-conduction efficiency of aluminum. They ensure constant warmth throughout your space by dispersing heat evenly from the bottom up thanks to their bottom supply. This design offers a practical and dependable way to keep your house warm during the winter months by maximizing energy efficiency and minimizing heating expenses.

Radiators with bottom connection

Bulky pipes can be concealed if the heating system has a bottom connection. Naturally, understanding the conventional system—in which coolant enters from the top or side and exits downward—is easier. However, such a system is unsightly, and covering it with a screen or elevating it in some other way is challenging.

The principle of the bottom connection

Heating pipe schemes with bottom connections are uncommon and less common because they are inefficient compared to standard connections. However, there are times when it is a wise choice. This kind of piping is not utilized in multi-family apartments. This kind of connection is typically found in private residences with bimetallic and aluminum radiators.

The majority of the pipes at the bottom connection are concealed beneath the floor covering; occasionally, seasonal inspections and preventive maintenance are challenging. However, there are benefits as well. There are fewer intricate bends or joints, which lowers the possibility of leaks or accidents.

The supply and return pipes are positioned adjacent to one another in the radiator’s bottom corner, making the connection scheme for heating radiators of the bottom type simple. Additionally, pipes from various radiator sides can be connected. If there are any upper holes, they are sealed with a plug.

The radiator installation kit and the typical one are the same:

Bimetallic radiators work best for the bottom connection. They radiate, heat, and convect heat very well, and they are robust and long-lasting. The heat loss will be no more than fifteen percent, even with a bottom connection. The radiator’s top warms via convection as a result of the hot coolant flowing from below, heating the radiator’s bottom.

Homeowners seeking cost-effective heating options are increasingly favoring radiators with bottom supplies. The room will always be comfortably warm thanks to the uniform heat distribution provided by these radiators. Because of their distinctive design, they make use of the natural convection process, which involves heating and recirculating cold air that is drawn in from the floor into the space.

The longevity and corrosion resistance of bimetallic radiators are two of their main benefits. Steel is used for strength in the construction of these radiators, while aluminum is used because of its superior heat conductivity. This combination guarantees that the radiators will not only last for many years, but will also distribute heat efficiently, saving homeowners money on energy costs over time.

Furthermore, bimetallic radiators with bottom supplies provide flexible installation options. They are a flexible option for a range of home configurations because they are simple to incorporate into both new and old heating systems. These radiators can be customized to match your unique heating requirements, whether you’re building a new home or remodeling an existing one. This will give you a dependable and effective heating solution.
