When arranging an apartment or a house, it is extremely important to choose the right heating radiators. They differ from each other structurally, according to the material of manufacture, weight, power, appearance and heat transfer. All batteries, however, work on the same principle. It lies in the fact that a hot coolant enters the case, which heats the radiator material, and then it gives off heat in the room by convection or thermal radiation. In the first case, we are talking about accelerated heating.
Which radiators to choose
On sale you can find batteries that are convector-radiators, they combine both functions. The room will warm up faster if there are such devices in it. This distinguishes them from simple radiators, which supply heat in the form of thermal energy in the amount of 60%, while 40% is given off by convection.
Batteries, among other things, can be divided into 2 more groups. The difference lies in the design features. Devices can be sectional or panels. In the firstthe case in question is:
- bimetal;
- steel;
- cast iron;
- aluminum.
Panel batteries come in a variety of designs and are combined appliances. They work by giving off thermal energy and heating the premises by convection. If you need a heater, you should pay attention to Kermi radiators, reviews of which you can read in the article.
Device
The design of the Kermi batteries is quite simple. The equipment consists of two steel plates, the thickness of which is between 1.2 and 2 mm. There are also vertical channels where the heated coolant circulates. All elements are connected by welding. Some models have ribs on the back side, which helps to increase heat transfer. This design of Kermi radiators, reviews of which are quite often only positive, is called combined. The panels give off thermal energy to the room, and the space between them - convection. The design has such features that contribute to rapid heating, but also rapid cooling.
Consumer reviews. How it works
Reading reviews of Kermi radiators, you can understand that these panel devices are among the best. These are products of a German company, the performance of which is considered the best in its class. As consumers emphasize, products are made from cold-rolled sheet steel. Its thickness is 1.25 mm. Customers love that these appliances are perfect for Russian conditions, where the climate is frosty and sudden temperature changes are quite common.
From the reviews of Kermi radiators, you can understand that they are suitable for rooms of any size, although they are small. The height can vary from 30 to 50 cm, while the width is equal to the limit from 0.7 to 1 m. Three depth options act as the main feature. This figure varies from 59 to 100 mm. An intermediate value is 64 mm. Even the deepest radiators do not recede much from the wall, so they remain almost invisible in the interior.
Customers note that the surface of the batteries is varnished. Any device can be connected to autonomous or centralized heating, to a one-pipe or two-pipe system. According to the type of connection, the devices can be divided into FTV and FKO. The former assume a bottom connection, while their external thread is 3/4 inch. The second type provides for lateral connection, and the internal thread is 1/2 inch. Each species has three series:
- single-row;
- two-row;
- three-row.
Production Features
The production of models uses a new technology that provides the initial heating of the front panel. There is a direct flow of water from the heating system. After that there is a gradual heating of the rear panel, from the reverse current of the coolant. The rear panel acts as a heat shield. Surface of radiatorsdegreased and primed, then varnished.
At the final stage, the product is subjected to heat treatment and enamel coating. This approach ensures the durability of the layers, which are almost impossible to spoil. In the production process, the company does not use formaldehydes, which makes the devices environmentally friendly, so the feedback on Kermi heating radiators is almost always only positive.
Connection Features
Kermi radiator models are manufactured in the most popular sizes for ease of installation or replacement. The manufacturer has taken care to facilitate the connection task by providing instructions. So, before starting work, you should calculate the power. Productivity is calculated according to the following formula: 100 W + 1 m². The radiator can be selected by determining the heated area.
Reading reviews of Kermi steel radiators, you will be able to understand that the minimum installation height from the floor is 10 cm. It is important to exclude the product from adhering to the wall. The minimum gap is 5 cm. It is recommended to use branded components during installation. Wall mounts are included. To be purchased separately:
- control valves;
- shutoff valves;
- lower connection node.
After reading people's reviews of Kermi radiators, you can note for yourself that when batteries are connected in series in a single-pipe system, work should be done throughadapter. In a two-pipe system, the installation of additional nodes is not required. A Mayevsky crane is installed on the radiators, which allows, after filling the pipeline with coolant, to bleed air from the system. Bleeding should start from the radiator closest to the boiler.
Reviews of radiators with bottom connection
Reading reviews of Kermi radiators with a bottom connection, you will be able to understand that they are panel and tubular. This name was given to the devices because of the design features. The appliances have flat heating panels and linings when it comes to panel construction. This prevents the accumulation of dirt. For tubular devices, the distance between the tubes has been increased. This makes it easy to clean the battery. Customers like these models because they use sequential heating technology. Thanks to this, the user has the opportunity to save up to 11% on energy costs.
If you liked Kermi steel heating radiators, you should definitely read reviews about them. After reviewing the opinions of consumers, you can find out that such devices, which are most often installed in private houses and cottages, have an attractive appearance, because the pipeline is located below, which allows you to hide the eyeliner. Tubular steel radiators are easier to connect, panel options are difficult to install, but they are easy to integrate into the laid line.
Reviews on Raden radiators
If youstill unsure of the choice, it is worth considering others. Reviews of Raden and Kermi radiators are generally positive. The first of the mentioned brands is located in Italy. The cost of one section is 2 times lower than that of Kermi radiators. Batteries are made of bimetal, and the maximum working pressure is 25 atmospheres. The height of the batteries varies from 241 to 552 mm. Consumers like the heat dissipation of one section, which reaches 185 watts. The heat output of the Kermi panel is somewhat lower and starts at 179 watts. However, the maximum limit is quite high. The final value will depend on the specific model.
In closing
German heating systems have always been distinguished by impeccable reliability and quality. Kermi products are no exception. The equipment from this manufacturer is adapted to the operating conditions in Russia. Thanks to this, technical conditions have been significantly improved. "Kermi" are highly resistant to hydraulic shocks, they have high thermal conductivity and are able to withstand the effects of an aggressive coolant environment.
