Batteries with bottom connection

It can seem like an ongoing struggle to keep your house warm and comfortable during the cold months. A properly heated home is essential for comfort and wellbeing, whether you’re lounging with a good book or hosting guests. The kind of batteries you use is one essential element of an effective heating system. We will examine bottom connection batteries in this post and see how they can help make your home’s insulation and heating system work better.

What are bottom connection batteries specifically, and how are they different from other kinds? In essence, bottom connection batteries differ from top connection batteries in that the connections are placed at the bottom of the device. Your heating system’s efficacy and efficiency may be significantly impacted by this small but important difference.

The ability of bottom connection batteries to disperse heat more evenly throughout the space is one of their main benefits. These batteries make sure that heat is distributed from the radiator’s lowest point by placing the connections at the bottom, which promotes more even warming of the surrounding air. As a result, there are fewer cold spots and the temperature is more evenly distributed throughout the room, making it more comfortable.

Furthermore, bottom connection batteries can help raise your heating system’s overall efficiency. Through the optimization of the hot water flow via the radiator, these batteries can minimize energy loss and minimize your heating expenses. This is especially advantageous for homeowners who want to reduce their long-term utility costs and their environmental impact.

In addition, compared to their top connection counterparts, bottom connection batteries are simpler to install and maintain due to their design. The radiator’s bottom contains the connections, making installation easier and requiring less time and effort. Furthermore, you can save time and money over time by performing maintenance tasks like replacing valves and bleeding the radiator more easily.

Type	Pros/Cons
Panel Radiators	Pros: Efficient heat distribution, space-saving design. Cons: Limited design options, may not fit all spaces.
Convector Radiators	Pros: Quick heat output, suitable for larger spaces. Cons: Can be less efficient at distributing heat evenly.
Low-Level Radiators	Pros: Ideal for rooms with large windows, provides consistent heat. Cons: May not heat the entire room evenly.

The main ways of connection

Note right away that there are a number of these techniques. We only plan to take into account the most well-liked ones. These are as follows:

For centralized heating in multi-story buildings, the first connection type is utilized. In this instance, pipes are connected to the battery only on one side, maximizing the use of each device’s nominal capacity. However, the number of sections will have a major impact on the heating quality. The heated liquid, for instance, won’t be able to reach the sections that are farther away from the connection if the connection is one-sided. This especially holds true for appliances that have fifteen sections. Put another way, it is preferable to use an alternative connection method for batteries that have a lot of sections.

Additionally, a diagonal scheme—also known as a cross—is employed with the kind of bimetallic radiators that are so popular today. It is made up of the following pipes: the outlet pipe connects to the other side of the battery through the lower pipe, and the underwater pipe goes through the upper pipe. Since the coolant is dispersed more evenly in this instance, heat loss is greatly decreased.

However, some rooms make it impossible to do any of the aforementioned options. In this instance, bottom-connection heating radiators are utilized, where the heater’s input and output are positioned on different sides. Naturally, the liquid does not reach the upper portion of the sections with such a thorough movement, resulting in a 15% reduction in heat output. Nonetheless, in private homes with separate heating systems, this kind of arrangement is highly common.

Crucial! Use of special distribution pipes can offset heat losses.

Design features of the bottom type connection

These days, unique radiators that are connected at the bottom are sold. They are designed to produce the most heat possible, and one of their standout features is the usage of a plumbing node (bypass plus fittings).

These batteries are made up of two steel plates (the previously discussed panel devices), joined by welding. It was made possible to arrange the technical channels that the fluid travels through thanks to this. To prevent rusting, two coats of varnish are applied to each plate.

Designation of radiators with bottom supply

Side-connection pipes and racks are hardly enough to adorn a house. Naturally, not too long ago, the buyer was limited to what was offered on the market and had no other option. When they figured out a way to conceal the dubious pipes beneath the floor, however, the interiors of a lot of country homes underwent an odd makeover.

Crucial! It should be mentioned that in this instance, connections can be made directly as well as with the use of a bottom connection block, a unique device. This device works on the principle that radiators don’t need to have their liquid drained in order to be disconnected from the mains. Stated differently, there’s no reason to disconnect the heating system as a whole.

These days, steel tubular radiators and panel radiators both have this built in (aluminum or cast iron devices can not provide this opportunity). And while everything about tubular radiators is obvious because we have been using them for a while, panel devices can be identified by their thermostatic fittings and multiple groupings.

Classification of panel devices

Three varieties exist for panel radiators:

Sheet steel is used in the production of profiled devices, and all external surfaces are covered in a protective powder coating. Furthermore, the service life is greatly increased by the neutral anti-corrosion varnish, which is also utilized in the manufacturing process. There are no limitations on the color; it can be any color.

Hospitals, kindergartens, and educational institutions all use the second and third types of radiators. Good examples are goods from companies like Purmo or Kermi, for example.

Crucial! One of the benefits of using tubular radiators over panel radiators is that the former can be installed with either side facing up, while the latter need to be bought with a specific connection already made. Additionally, the pipes in older buildings might not match the modern radiators. Although there is a solution, it will involve rearranging the pipeline.

Bottom piping – how it can be?

It can also be one of two kinds.

1. In the case of One-way piping both pipes are connected on the same side of the heater. One of them – the upper one – supplies the heated coolant, and the second one – the lower one – discharges the already cooled coolant.

В versatile version hot liquid is supplied to the radiator from one side, and cold liquid is discharged from the other side. It is worth noting that for individual type heating this method is more suitable. The advantage is that the coolant can circulate in almost any direction, as well as in the small length of supply/return. Although the decisive role, of course, the required heat transfer plays a decisive role.

The main advantages of the bottom supply

As noted earlier, this method provides for the supply of hot fluid to the radiator from one side, and the output of cooled – from the other side. Thanks to this, the pipes can be easily hidden without losing much of their efficiency. And the radiators themselves from below warm up faster than from above due to the high speed of water circulation. At times, the efficiency of the equipment in operation is reduced due to the main line being bled or clogged. But even after that, this method of supply provides uniform heating of devices (the efficiency is not lower than in the case of the upper supply). Important! Regardless of which method of connection has been chosen, a number of special requirements should be adhered to during installation. And it concerns first of all the ratio between the width of the radiator and the same indicator of the window.

Basic requirements for installation

1. tube in the form of the letter "G";
2. mounting level;
3. multiflex;
4. FUM-tape;
5. thermal insulation;
6. pipe cutter;
7. appropriate number of nuts.

Crucial! When starting repairs in the living room, it is advised to make the connection at the bottom. This can be explained very simply: in this instance, the piping is installed in the floor or wall. Thus, even before the concrete screed is poured, this needs to be taken into account.

Radiators typically come with mounting kits or assemblies of their own, allowing them to be fixed to the wall.

Step 1: There should be a minimum of 15 centimeters between the radiator and the floor, and 2 centimeters between it and the wall.

Step 2: Firstly, a construction level is positioned on top of the radiator, which is mounted on a unique stand.

Step 3: After the apparatus is level, the fasteners must be hammered in, but only after the number of sections has been determined. For instance, two fasteners will suffice if there are only five of these sections; however, if there are seven or more, a third fastener might be required.

Step 4: The radiator is installed and fastener holes are made.

It’s also important to note that L-shaped pipes must be foam-filled and strengthened when connecting using the lower method. However, this ought to wait until the installation is finished and the heating system has undergone a pressure test.

Here are a few more helpful installation hints. It’s crucial that the supply and return pipes are kept separate, but all you need to do to ensure this is to read the matching factory markings. Yet, you should exercise extra caution if connecting both tubes from the same side. In actuality, the device’s performance can drop by 50–60% if they are connected improperly (a more precise percentage may vary depending on the features of a specific model).

It is recommended that you become acquainted with the correct procedure for replacing the radiator heating. in depth

Currently available models come with a thermostatic insert that controls the device’s temperature. However, the inclusion of this insert has also increased the price (by about a tenth compared to other models).

Manufacturers and cost

The best manufacturers of bottom-connection radiators are Finnish (PURMO) or German (Kermi). However, excellent gadgets are also made in Italy, Austria, and even the CIS nations.

When it comes to price, a decent radiator should typically run you between 4500 and 5000 rubles.

As a conclusion. How to choose the right connection method?

If you are unsure about your options, start by paying attention to the battery installation scheme, t. к. It is primarily dependent upon the functionality and performance of the devices. Additionally, breaking the installation guidelines may cause an abrupt pressure surge in the system with unpredicted results. Additionally, you run the risk of ruining the room’s interior if you decide to install it yourself without the necessary abilities or understanding.

Bottom connection of heating radiators

What should be done if the room’s appearance is ruined by the heating system? What should be done with the pipes if cast-iron batteries can still be concealed behind a screen or if more contemporary steel or bimetallic batteries are installed in their place? Some people use drapes and curtains to cover them. and others handle the radiator heating bottom connection; as a result, the battery piping is essentially invisible.

Features of the bottom connection

The open type’s bottom connection

Three methods of communication:

1. Connection of ordinary radiators through the bottom holes.
2. With a set of accessories from the bottom of steel or bimetallic heating batteries.
3. Purchase radiators that are designed for this connection.

Let’s now examine the approaches, benefits, and drawbacks of various bottom connection strategies.

Connection with side taps

Two-way connection at the bottom

The connection is not too difficult in and of itself. The pipes are at the bottom, either concealed in the floor or above it. The piping is attached to the bottom holes and the radiator is fixed to the wall. A shut-off valve needs to be placed on both sides of the radiator in order to remove it without interrupting the heating process. The upper opening has an air vent installed, regardless of which side it is on.

Connection with adapter

Scheme of connections There are situations when connecting a standard radiator with plumbing on both sides is not feasible. An adapter can be used in this situation. A stainless steel tube is brought from the lower hole to the upper hole by screwing it into the lower hole. The heating pipes are connected from below to the adapter itself.

Watching the video that is attached at the end of the article will give you more details about this kind of connection.

Bottom connection with flow extender

A flow extension device can be used to make the lower connection. There are no branches leading to the upper hole; the device is screwed into the bottom hole. Water that travels through the radiator’s center tube, exits it at the heater’s end, rises, and squeezes cold water through the device’s outlet hole is what causes the coolant to circulate.

Gravity-flow systems are not appropriate for this kind of connection.

Plumbing connections inside the wall

We will now focus on the method of bottom connection that is more effective and aesthetically pleasing, which is from below, briefly discussing its benefits and drawbacks.

Advantages

Adapter for flow direction

• It is possible to install a flow direction adapter.
• Both pipes directly from the radiator go into the floor or wall (or into pipes above the floor).
• Buying radiators with bottom connection, you do not need to worry about buying a suitable thermostat, as it is already installed there.

Disadvantages

The radiator needs to have its air bled out.

• An air vent must be installed on each radiator .
• Heating is less uniform and not as efficient.
• Cannot be used for gravity-flow heating systems .
• A circulation pump must be used at all times.

Radiator arrangement norms

Norms for radiator arrangement are followed

No matter which radiator connection method is selected, it needs to be placed some distance away from the radiator:

• wall – 5 cm;
• floor – 10 cm (deviation in any direction is allowed not more than 2 cm);
• window sill – 10 cm (a minimum distance of 5 cm is allowed).

It is crucial to consider the thickness of the installed thermal insulation with a reflective layer (if applicable) when making a mount purchase. In this instance, slightly longer fixing hooks are needed.

Installation of the heating system with bottom supply

Custom fittings are used to make the connection.

The installation of the piping is contingent upon the selected plan. It is stackable:

The location of pipes—which are concealed for aesthetic reasons—has no bearing on the heating system’s efficiency.

It’s crucial to install the radiators first, figuring out how many are needed for each room, and then run pipes to them.
