Tool Reviews

Radiators made of two types of metal are called bimetallic. The steel core excludes contact of the heat carrier with the aluminum case. Units with a center distance of 500 mm (number in the name of the product) have the highest heat transfer, are able to quickly heat up a room with an area of ​​8-24 m².

How to choose a bimetallic radiator

When choosing a model, pay attention to the country of origin. Chinese appliances are cheap, but quickly fail. Domestic radiators are inexpensive and of high quality.

Important

For a successful choice, it is important to pay attention to the following parameters:

• the number of sections – the more there are, the faster the room will heat up;
• heat transfer coefficient – the higher the indicator, the more efficient the heater works;
• the presence of a factory marking on the device – this guarantees the originality of the radiator;
• is there an external wall in the room;
• the presence of joints in the body;
• connection method – some of the units have a bottom connection;
• the presence of adapters in the configuration – if they are not, you will have to buy separately.

Doesn’t matter

• heaters are made in a universal white color (with rare exceptions), they are suitable for any room;
• model design is standard.

The most popular models are presented in the review.

The best thin bimetal radiator

Italian heater Rifar Alp 500 has a 10-year warranty, subject to the rules of transportation and installation. With good care, it has been working for 25 years. This is the thinnest heater without compromising on thermal performance.

Characteristics

Heat transfer by number of sections and height, width, depth in mm:

• 4 sections – 764 W, dimensions 570x324x75;
• 6 sections – 1146 W, 570x486x75;
• 8 – 1528 W, 570x648x75;
• 10 – 1910 W, 570x810x75;
• 12 – 2292 W, 570x972x75;
• 14 – 2674 W, 570x1134x75.

Mounting method – on the wall, top side connection.

pros

The color is selected according to the catalog, the design is universal and suitable for a city apartment and a country house. The original technical solution made it possible to achieve high heat transfer with a small width. This is done due to the large area of ​​​​the lateral part. The model is suitable for rooms with large window openings. The sections are made of aluminum, which makes them lightweight and increases the heat dissipation of the system.

Minuses

Specially prepared water is required for pumping into the system. The sections are sealed using specially designed parts and a silicone gasket. For repair or replacement, you will need to look for original spare parts.

The best bimetal radiator with bottom connection

Section heater Rifar Monolit Ventil 500, like all models of the Italian manufacturer, has a guarantee and is maintained in the standards in force on the territory of the Russian Federation. The word “monolith” denotes the operation of the device in difficult conditions, the “valve” in the name of the model range indicates the lower connection to the heating system.

Characteristics

Is issued in options from 4 to 14 sections. The coolant can have a maximum temperature of + 135˚. Water pressure: working – up to 100 atm, test – up to 150 atm.

Heat dissipation in W and dimensions in mm:

• 4 sections – 784, 577x320x100;
• 6 – 1176, 577x480x100;
• 8 – 1568, 577x640x100;
• 10 – 1960, 577x800x100;
• 12 – 2352, 577x960x100;
• 14 – 2744, 577x1120x100.

Models have right and left connections.

pros

The thickness of the steel from which the sections are made corresponds to the thickness of the water pipes. Such parameters make the case more durable. The fragments are connected by specially designed knots and reinforced with silicone gaskets of a special design. This eliminates the possibility of radiator leaks. There are no intersectional joints in the design.

There is no need to select adapters with left or right threads.

No cons found.
