Installation of radiators

This WordPress post covers the installation of radiators, an essential part of any home's central heating system. It provides detailed information on the types of radiators available, how to determine the number and size of radiators needed, and the specific steps necessary to ensure a successful installation. This post emphasizes the importance of using qualified and experienced professionals for the job, offers key safety considerations, and outlines the benefits of using a reliable supplier. With its simple instructions and helpful tips, this post is an invaluable guide for homeowners looking to undertake a radiator installation.

A water heating radiator, or, as it is also called, a battery, is familiar to everyone. It is this device that creates warmth in our apartments in winter. Progress does not stand still, and a new generation has come to replace the cast-iron monsters of Soviet times โ€“ aluminum bimetallic and steel panel radiators that look good and are easy to install.

Often, the choice of radiators is carried out as follows: first โ€“ aesthetics (otherwise, why change reliable, but clumsy cast-iron batteries), then โ€“ the price and then the technical parameters.

We offer you a different scheme: technical parameters (the reliability of heat supply depends on them), aesthetics, and then the price.

So, what technical points should you pay attention to when buying a radiator? If you want the battery to serve for a long time, you need to choose it correctly and correctly mount it.

When choosing a radiator, pay attention to the working pressure โ€“ this is the pressure for which the device is designed. For devices installed in city houses, it should be at least 9-10 atmospheres, and the larger it is, the more reliable the device. True, if the house has an individual heating unit (its own boiler room), then devices for 6-8 atmospheres are suitable, provided that the house is not a high-rise.

Next, you need to decide on the thermal power of the devices. You can proceed from the calculation of 100-125 watts of heat transfer from the device per 1 sq. m. area of โ€‹โ€‹the heated room. How much each device gives out, you will find out from the seller. For a preliminary estimate, this is sufficient.

What are the reasons for the decrease in heat transfer from devices? The radiator generates 15-18% less heat for every 10 C decrease in water temperature. If water is supplied to the lower hole of the radiator, and comes out of the upper one, then the radiator does not supply another 7-10% of heat. Best of all, when the water is supplied from top to bottom. If the connections to the radiator are located on one side of it, then making the number of its sections more than 10 is meaningless, because the distant sections will be weak. For long radiators, the inlet and outlet must be made from different sides of the device. If the radiator is installed in a niche, under a windowsill, then there should be enough space around it for air movement. Therefore, the distances should be at least: to the floor โ€“ 70-100 mm, to the wall 30-50 mm, to the windowsill 100-150 mm, otherwise 10-15%. By the way, a lightweight decorative casing installed in front of the radiator, or blackout curtains that go down to the floor, can take away all 20% of the heat.

The radiator is mounted either in the wall version or in the floor, using brackets.

And now about what you need to consider when installing a radiator:

  • the maximum temperature of the coolant should not exceed 130 ะกo
  • water quality must meet the requirements of RD 34.20.501-95
  • it is strictly forbidden to dehydrate the heating system (regardless of the season)
  • it is strictly forbidden to use heating main pipes as elements of electrical circuits.

And now about some of the features of installing radiators:

Steel panel radiators:

Such radiators are made of two steel plates, 1.25-1.5 mm thick and connected by welding. The large area of โ€‹โ€‹the fins increases the heat radiation of the radiators. After installation, the radiator is usually covered with a casing โ€“ it gives it an elegantly strict look.

This category of batteries operates at pressures up to 9 atmospheres and gives off heat about 20-25% more than conventional radiators.

In addition to the standard mounting kit, which is usually sold with the radiator, there are a variety of fasteners that allow it to be installed in a floor-standing version with adjustable distance from the floor. Radiators have only side connections or side and bottom connections.

Sectional aluminum radiators:

Aluminum sectional radiators โ€“ elegant, light, with high heat transfer โ€“ are the most popular on the Russian market.

Aluminum has a high thermal conductivity (3-4 times higher than that of cast iron and steel), which makes it possible to create radiators with high heat transfer in a fairly compact size. The length of the radiators (and, accordingly, their power) is easy to select by changing the number of sections used. Each section has upper and lower collectors, connected by a vertical channel, and special elements (ribs) that increase the surface and, accordingly, heat transfer.

In addition to high heat transfer, aluminum has properties that make it possible to obtain a very complex shape of products in the manufacture of elements by casting.

Sectional bimetallic radiators:

This type of radiator successfully combines the best properties of sectional aluminum and tubular steel radiators: strength (withstand pressure up to 40-50 atmospheres), durability (service life โ€“ up to 20 years) and a high level of heat transfer combined with a modern design that will fit into any interior.

The bimetallic radiator uses two metals โ€“ steel and aluminum. The steel core reinforces the structure of the radiators. Thanks to him, they withstand high pressure. In addition, steel filling reacts more calmly than others to the alkalinity of water (ph-factor). Aluminum has a high thermal conductivity, which significantly improves the heat transfer of the radiator and reduces its inertness. Such a heater heats up and cools faster. In order to avoid problems with installing the radiator, you need to decide in advance on the dimensions of the devices, with the diameter of the supply pipes and the scheme of their connection to the device: from the floor (one or both pipes) or simply from the bottom of the floor or plinth, from the back from the wall, from above , from the side. When repairing with the replacement of radiators, it is important to know the required center-to-center distance between the holes for the connections. All this will help to avoid unnecessary hassle and costs for installing different adapters, bending pipes, and also facilitate the selection of related accessories.
