Top 18 bimetallic heating radiators: Rating of the best models of 2022


Bimetallic radiators are a type of battery that is made of different metals: internal channels are made of stainless steel, the external heat exchange body is made of aluminum. Stainless steel is resistant to aggressive coolant environments. Aluminum has excellent thermal conductivity and heats up quickly. There are sectional and monolithic structures. Used in central and autonomous heating systems.

When studying the huge range of batteries for heating rooms offered on the Russian heating engineering market, the consumer often has the question of which bimetallic heating radiator is best to choose for an apartment or private house.

The choice of bimetallic radiators is becoming increasingly important today. This happens because in one design of a heating device, the positive qualities of two metals - steel and aluminum - are used to the maximum.

This combination provides a number of advantages compared to devices made from the same material. The frame made of steel water pipes in an aluminum alloy shell is a bimetallic radiator, comparable in thermal power to aluminum and steel heating devices, and in reliability to cast iron radiators.

Which bimetallic heating radiators are best suited for each specific case must be determined individually. A suitable model is selected based on a number of criteria such as the type of bimetal, steel thickness, and thermal power.

The type of model and the calculated pressure are also important. In addition to technical characteristics, the choice of a particular device design is influenced by its cost and attractiveness of design.

Types and comparison of designs of bimetallic radiators

Based on the method of forming radiator housings, they are divided into two types - monolithic and sectional devices.

DO NOT BUY Radiators Until You See THIS!!!

Monolithic

Monolithic or panel bimetallic batteries are reliable and high-quality heating devices made from steel tubes welded together, covered with an aluminum alloy shell on top.

Non-collapsible panels have a pleasant appearance that harmonizes with any interior. The devices are produced in a wide range of sizes. The range allows you to choose the dimensions of the panels to suit any heating area. The only drawback of monolithic models is that they cannot be disassembled. If they fail, such batteries cannot be repaired.

Sectional

Batteries of this class are prefabricated structures consisting of several vertical hollow flow-through vessels (sections) connected by fittings (nipples) with external threads. Their number can be any and is determined by thermal engineering calculations. A single panel is assembled with a special socket wrench, screwing the nipples into the horizontal manifold holes of the sections.

Based on operating conditions, the number of sections in sectional devices is increased or, conversely, reduced, which is a definite plus.

Unlike monolithic products, batteries are repaired by replacing damaged elements with new vertical elements.

Bottom line

If you have doubts about which heating battery is best when buying, reviews from users who have already purchased this or that model will help you decide much better than recommendations from consultants or advertising characteristics of manufacturers.

Focusing on buyers from all over Russia and the specific situations they used when choosing a radiator, we will help you choose a Russian or foreign model that will look good in the interior of a private home and provide warmth in the cold winter.

What do we pay attention to when choosing

First of all, you need to be interested in the certification of the product, the rating of the device on the network, and the authority of the manufacturer in the heating engineering market.

The service life, the ability to wash and replace damaged sections of heating devices are important. It is necessary to pay attention to the following list of characteristics, according to which you can choose the best model of bimetallic heating radiators. Below we will look at them in more detail.

Maximum pressure

A very important parameter. If there is a sudden increase in hot water pressure in the heating system, the radiator can simply burst. Centralized heating systems suffer from this disadvantage. When choosing bimetallic batteries, this point must be taken into account.

In private homes, as a rule, balanced water heating systems are installed, in which the pressure is maintained at a safe level. On average, bimetallic models can withstand operating pressure within 25 bar, and water hammer is not dangerous up to 35 bar.

Center distance

The center-to-center distance is the distance between the centers of the holes of the inlet and outlet manifolds (horizontal steel tubes). The dimensions of the device, and therefore the size of the heat transfer area, depend on this size.

The greater the center distance, the better the heating battery works. The standard sizes for this parameter are 500 mm, 350 mm and 200 mm. Along with this, there are models on sale with different center distances.

Heat dissipation

When determining the best bimetallic batteries, such a characteristic as heat dissipation plays an important role. In the accompanying documentation of its products, the manufacturer usually indicates what heating area the panel or one section of the radiator is designed for.

Below is an example of calculating the heat transfer of bimetallic radiators.

Reliability

The manufacturer provides in the instructions the maximum pressure values ​​in the heating network for bimetallic radiators. In residential premises with unstable pressure in the central heating network and the risk of water hammer, it is not recommended to use devices of this type.

When deciding to connect bimetallic batteries to an autonomous heating system, sales consultants at construction hypermarkets can advise which models of bimetallic heating radiators are more reliable. Below we will cover this point in more detail and consider the Top best models of each type, most of which can last about 40 years.

Design

The appearance of room heating devices plays a big role when choosing a particular model of bimetallic radiator. The beautiful shape of monolithic panels and sections with their aluminum converter curls create an attractive image of the products.

The choice is also influenced by the color of the batteries. Light gray tones suit many interiors. For lovers of extravagant styles, you can purchase modern heating devices painted in radically bright colors.

Criteria for choosing a bimetallic battery

When choosing which radiator is best to purchase for a house or apartment, you need to correctly determine its characteristics. Experts recommend taking several key criteria as a basis:

  1. Type: sectional or monolithic . The first are universal and allow you to “assemble” a radiator of optimal size, the second are more reliable, since their design does not contain places where leaks are potentially possible, and their service life is increased to 50 years. Of those presented in the rating, some are monolithic Rifar Monolit Ventil 500, produced using a unique technology, others are sectional, they are more in demand on the market by buyers.
  2. Heat dissipation. It is easy to calculate using the standard formula: 100 W per 1 sq.m. area. The indicator should be increased by 30% if the room has two or more windows, or by 40% if they face the north side. However, other factors need to be taken into account - ceiling height, presence/absence of heated floors, location of the apartment/room in the house.
  3. Connection type - it can be bottom, top or non-standard.
  4. Design. Modern radiator models are varied, you can find very interesting options, such as Royal Thermo PianoForte 500 or Royal Thermo BiLiner 500. Timeless classics have also become more varied, but have retained rigor and minimalism.

Which bimetallic heating radiator is better to choose for an apartment?

When installing new and replacing old heating devices in apartments with bimetallic products, it is necessary to take into account the boundary parameters of the operating pressure for which it is designed.

You also need to take into account the quality of the coolant and if it is low, then you need to choose models in which the steel frame made of tubes is treated with an anti-corrosion internal coating.

The best radiators for apartments will be batteries that can withstand pressure surges of up to 30 atm. It is important to take into account the standard pressure in the centralized heating network.

Radiators: aluminum or bimetal? “Never bet!” And other myths.

Cast iron heating radiators: description and reviews

The main advantages and disadvantages of this type are discussed in our material: “Cast iron radiators: technical characteristics.” Most often, their modern models are used for heating private houses, since their use in apartment buildings is not recommended due to possible pressure drops in the heating system.


Cast iron radiators

Particularly popular are design solutions from European companies, which are quite expensive, but add special sophistication to the interior. To choose a specific model, you need to analyze its technical data and customer reviews.

Vasily P., Khabarovsk, private house:

A year ago, we replaced the old cast-iron radiators with designer Demrad Retro models from a Turkish company, and they struggled with the installation, despite the fact that it took three of us to do it. Very heavy, I had to install additional brackets. They look perfect in the interior, but are a little bulky.

How to calculate the number of sections

We suggest using an online calculator to calculate the number of heating radiator sections by room area.

Each manufacturer of sectional bimetallic radiators indicates the power of one section in the accompanying documentation. For example, a section with a power of 1.85 W is capable of heating 1.5 m2 of room area. Dividing the area by 1.5, the required number of vertical segments of BM batteries is obtained.

If there are two windows in a room, and 20 sections are required for heating, then radiators with 10 sections are installed under each window sill. When calculating, the condition and material of the wall fences of the room or the house as a whole are also taken into account. If the structures are more than 20–30 years old, then experts advise using a coefficient of 1.2 when calculating the number of sections.

Reviews from experts

Professional builders know all the intricacies of operating heaters. Here are some tips and reviews.

  1. When installing the heater on the pipes, it is necessary to install a jumper. And so that in the event of an accident you can quickly turn off the battery, taps - upper and lower - and a regulator are placed between the jumper and the heater.
  2. Do not block batteries with screens or screens. Bimetallic radiators are not designed for this. Otherwise, along with heat transfer, the reliability of the devices will also decrease.
  3. The radiator itself rarely leaks. The fitting connection to the radiator may be leaking. Therefore, the installation of the connection must be done carefully.
  4. It is better to entrust the installation itself to specialists. But if you decide to install radiators yourself, then you should carefully understand the issue. It is better to order components for installation in one place, for example, from the Teplomir company.
