What are the requirements for a heating radiator
When it comes to buying and installing new heating equipment in an apartment or a country house, the first selection criteria that come to mind are simple and straightforward. According to consumers' feedback, they can be summarized into five main groups.
We did not try to derive a rating of consumer preferences, so the most common wishes were arranged in random order. The ideal heater should:
- provide a comfortable temperature regime for any fluctuations and malfunctions in the operation of heat networks;
- be resistant to mechanical deformation and depressurization during hydraulic testing;more simply, do not leak when heat networks are put on seasonal verification;
- work flawlessly indefinitely for at least fifty years;
- have a modern and stylish design that fits seamlessly into the interior of any city apartments and country houses;
- sold at a reasonable( better low) price, which can be selected in a wide range of models.
In our opinion, all these needs can best satisfy the bimetal radiator, but it's better to choose it in a vast market in a calculated and prudent way.
Design and advantages of bimetallic radiator
Bimetal radiators have already confirmed their best performance, it remains to be understood, due to what they are achieved and how to use them correctly. Structurally, such a battery is a hybrid of a radiator and a convector.
The heat carrier is supplied to the battery by steel pipes( horizontal collectors and vertical jumpers) and transfers heat to the convection zone and to the aluminum housing of the bimetallic radiator. The high mechanical strength of steel welded joints, in contrast to pure aluminum radiators, ensures the reliability of the device at pressures up to 35-40 atmospheres, the excessive thermal conductivity of aluminum allows up to 80% of the delivered heat. A little more positive:
- aggressive, chemically unstable coolant does not come into contact with aluminum surfaces, so the lifetime of a bimetallic radiator in a heating system is determined by the quality of welding internal tubes;
- comparatively light weight( only 50% more than in pure aluminum) ensures easy transport and installation;
- low thermal inertia, allows good automation to quickly adjust the room temperature;alas, it is here that the lack of a bimetallic radiator is also detected: rapid reactive heating, cooling of the battery and, as a consequence, a short service life of the thermoregulatory equipment;
- high heat dissipation and bimetal radiator housing area, providing with equal parameters of the working fluid heating of a larger area of the living space.
Rating of bimetallic heating radiators
We note that the objectivity of this estimate is small, since it is not entirely correct to evaluate which bimetallic radiators are better based on feedback from customers, posts and Internet sales data. Nevertheless, the five most popular models invariably include the following heating appliances of this class.
- RIFAR Monolit( Russia): working and pressure testing pressure 40/60 atm( very high);section dimensions 577х80х100 mm, heat output - 196 kW, price per section - 610 rubles;the main advantage is the absence of inter-section joints and reliability.
- Global Style Extra 500( Italy): the center distance is -50 cm, the pressure is 35 atmospheres, the temperature of the coolant is up to 110 degrees, the price per section of the radiator is 740 rubles. In this case, magnificent design and quality of surface treatment.
- RoyalThermoBiLinerInox( Italy) - with an average price( 570-590) for bimetal radiators from this manufacturer, the anticorrosive properties of pipes in the contact zone with the coolant can be considered the best.
