The width, depth and volume of the coolant are the most important parameters for determining the efficiency of heating. The height of the heating radiators is also taken into account in the power calculations, so that all rooms are heated equally. These data are needed for the most accurate calculations when you need the total return of the heat circuit in a private house. During the repair, the overall dimensions of the battery mounted in the window sill are also important.

Choosing the parameters of heating devices
Manufacturers offer a wide range of heating appliances so that everyone can choose with the most suitable parameters for their conditions. A competent calculation of heating requires an understanding of how the dimensions are interconnected - the width and height of the cast-iron heating radiator, a certain format. Some models have such a structure that it is impossible to build them up. Some can be adjusted by increasing the number of sections. But it’s impossible to change their height, it’s really only possible to raise a decorative shield in order to fill a niche in a window sill for the sake of improving the design.
The dimensions of a bimetallic or cast-iron block directly affect its power - the total amount of heat released into the room per unit time. According to these parameters, their efficiency is determined, therefore, the format of heating radiators is introduced into all calculators - dimensions in height and length. For the efficient operation of cast iron batteries or bimetallic radiators, a minimum interval must be observed during installation. This is necessary so that streams of warm air freely bend around the radiator from all sides. Therefore, 8-10cm is left from the floor, 5-15cm from the wall, about 10-15cm is left under the windowsill. The width of the battery should cover the niche under the window by at least 70%.
Advice! If the height is correctly selected, then the heating area of a radiator that is not too high will be operated more efficiently than a "multi-section" mounted closely.
It is worth considering that heating blocks of the same size, but differing in design and dimensions with a similar coolant temperature, will give a different amount of heat. This is due to the fact that they have a different surface area. Therefore, smooth panels of steel coolants are made with certain irregularities, and between the sections of bimetallic and aluminum heating radiators the minimum interval is set by the standard.
Choosing the size of heating radiators when buying from catalogs
Looking at the photos of radiators in catalogs and online stores, it is easy to notice that many new models differ from the classic ribbed batteries in all respects:
- design features;
- internal volume;
- outer surface area;
- connection method;
- thermal power;
- height, width and depth;
- number of sections;
- the presence of decorative elements;
- the main material for the manufacture of the blocks themselves and decorative elements.
Bimetal heating radiators have a steel pipe inside, cast-iron “accordions” have “ribs”. Panel models have a metal shield on the outside. With the same dimensions, different offers will have different indicators of thermal power. A reliable thermal curtain that blocks the cold sliding from the window cannot be ensured by a heating unit of a smaller format than is assumed. In the technical documentation of each model, all dimensions and important parameters are indicated, including the height of the heating radiators.
Note! Before buying, it is important to know the size of the window sill in order to determine if the selected models will fit in such a way that there is an air cushion for free passage of heat.
Evaluation of a heating radiator by height, depth, width and power
In order to choose the correct format of the heater when purchasing, all its parameters specified in the technical description of the model are taken into account:
- Width of heating radiators and height - from 200 mm to 1000.
- Depth of the model (how far forward protrudes from the window sill or other space).
- Thermal return (power).
The standard model, for example, for 10 sections, approximately should heat 1 living room in a city apartment. Externally, the same batteries, differing only in height, respectively, will pass through themselves a different volume of coolant. A higher heating radiator has more heat, a small one will not be able to work as efficiently.
Attention! In apartments and private houses with low window sills, a long floor battery is installed - a little more than 200 cm from the floor.
The project of the house does not always imply a sufficiently roomy window sill niche. In this case, combined thermal equipment is used, or high and narrow radiators and impressive thermal panels mounted along the walls. They can often be seen in gyms, pools, in cafes and on trading floors:
- Type RD with lower connections to the heating plant.
- Type R with side connection.
Low batteries provide a good thermal curtain at the panoramic window opening. A spacious room of large footage, it is desirable to additionally warm up the system "warm floor". As an option - low radiators around the perimeter of a spacious hall or living room. The only problem is how to decorate them in the interior. If the heating system is improperly designed and the height of the radiators is incorrectly selected, then in some places the room will be cold, and the battery will be hot. In the same way, the apartment will have cold and stuffy rooms; you will have to open the window in winter. If the windows sweat and the corners get damp, this is also due to a mismatch between the lack of insulation of the surfaces and the power of the heating block. Shut-off equipment on the radiator - the ability to control the temperature in the room.
Tips for installing thermal equipment
When replacing old ribbed batteries, it is important to consider the suitability of the radiators and utilities. There are radiators designed for closed loop and special antifreeze as a coolant. This equipment is designed for the private sector, it can not withstand a series of water hammer and pressure in more than 6 atmospheres.
The installation of new heating blocks of the premises implies the correspondence of the number of inputs to the battery by the type of connection:
- lower;
- lateral;
- diagonal.
If this amount is larger than required, plugs and a Mayevsky crane (above) are placed on free collectors. The cross-section of the pipes must coincide with these inputs, respectively, suitable connecting fittings are selected. It is advisable to select them directly when buying batteries.
