Choosing a complete set of equipment for heating housing, few people think about how to mount heating batteries. Most often, in the old fashioned way, it is supposed to bet on what comes with the radiators. Meanwhile, the right type of heating radiator bracket can help to improve heat dissipation and at the same time make the mount more secure.

How to choose wall brackets
It is not necessary to use the fasteners supplied with the purchased heating radiator.
You can find a lot of bracket options on sale:
- with adjustment of installation parameters;
- reinforced - for batteries with a large weight;
- wall-mounted, at least two dozen more devices.
They are in any construction supermarket, in Leroy Merlin, Epicenter. It is even better to contact a specialized heating equipment salon, for example, Rifar, where there are examples of installed brackets with radiators.
Do you like to do everything at home with your own hands?
When choosing a bracket, you need to consider:
- Fastening strength. You need to make a choice, choose a wall or floor installation option. The weight of the case with water turns out to be rather big, even for aluminum models. Therefore, if the walls in the house are finished with plasterboard, then it is better to choose a floor model;
- Complexity of installation. The bracket for the radiator should not be too difficult to install and adjust, otherwise it will be difficult to correctly align the position of the radiator with respect to the water drain line;
- The ability to adjust the distance of the heating surface of the radiator from the wall and window sill board.
Experts call the last condition the most important of all those given. Maximum heat dissipation is achieved only if the distance ensures the best flow rate of warm air between the wall and the back of the radiator. It is not always possible to correctly position the radiator relative to the wall the first time. Therefore, the problem is solved by using adjustable brackets.
When planning a suspension on wall brackets, leave a gap between the top edge of the radiator and the base of the window. For aluminum and bimetallic models, the gap should be at least 100 mm, for cast iron batteries - up to 20 mm.
The gap between the wall and the heating surface is recommended within the range of 30-50 mm, selected individually. If the temperature of the coolant is not more than 60 OWith, for example, when using an individual heating boiler, then the gap is reduced to 20 mm. The higher the temperature of the battery, the more the distance from the wall should be.
Bracket for cast iron radiators
Cast iron batteries traditionally hung on hooks made of forged or stamped fittings. They were driven into a brick wall by at least 20-30 cm, which ensured a reliable fixation of the radiators. Although such brackets looked rough, they were able to withstand the record weight of a cast-iron radiator without subsidence.
Installing the hammer brackets required skill and experience. Each hook was hammered into the wall according to preliminary marking so that the battery rests with the register necks on its concave part without sagging. It was difficult to do this, so each hook had to be knocked out with wedges. The slope of the drain line was adjusted in the same way.
In houses with concrete walls, cast iron radiators are placed on anchor brackets. They are no longer hammered into, but threaded into a dowel hammered into the wall.
Such a scheme makes it possible to set the cast-iron battery more accurately, if necessary, unscrew the brackets so that the heating surface of the radiator is parallel to the wall.
Anchor brackets are used for fastening all types of radiators, therefore, when purchasing, you need to pay attention to the hook material and the maximum load. For cast iron batteries, forged steel models with a diameter of 10 mm with a working load of up to 50 kg are suitable.
Wall-mounted welded brackets
Each fixture is a mounting plate in the form of a pair of hooks made of steel, 4 mm thick, welded to a support strip, 20 mm wide, made of the same metal. The distance between the support surfaces is 30 cm or 50 cm, the outreach of the support surface of the bracket is 80 mm and 95 mm.
Mounting plates can be installed on any type of wall, fastening is done with dowels or bolts. If it is a cast-iron battery, it is mounted on a wall inside the building.
Fastening cast-iron radiators with mounting straps has some nuances.
- It is necessary to accurately mark the position of the brackets on the wall. If a mistake is made, then both planks will need to be transferred.
- After applying the markings, the brackets are attached to the wall with dowels through the upper holes.
- The radiator is hung on the slats, its position is leveled, and only then the drill locations on the wall for the lower holes are determined.
Any other way of installing the mounting plates requires the use of a ready-made jig template. This option is used in residential construction.
Bracket for bimetallic radiators
The weight of bimetal batteries is several times less than cast-iron registers, so there is no special need to hammer long, forged "crutches" made of reinforcement into the wall. Bimetallic heating systems with a large number of registers are often attached using pin hooks.
Such a hook in design resembles an anchor for a cast-iron radiator, but its dimensions are smaller, the depth of immersion into the wall is halved. The support bar is covered with plastic or silicone.
Bimetallic heating radiators are also installed on lamellar corners.
The fastening scheme of panel steel heating radiators is somewhat different. The standard steel panel is attached by hanging loops welded from the rear of the radiator to several steel brackets pre-stitched to the wall with dowels. The number of brackets and hinges depends on the length of the radiator.
bracket steel radiator Is a steel corner with perforated mounting holes. During installation, the heating panel is laid in hinges on the teeth with inserts. Oval holes for dowels allow you to adjust the position of the dowels, and different sizes of the corner shelves makes it possible, if necessary, to unfold the fasteners and place the body at different distances from the carrier walls.
Bracket for aluminum radiators
For lightweight aluminum heating systems, corner types of fasteners are used. This can be a conventional steel stamped corner or a more complex welded version with a height-adjustable support surface.
As a rule, universal brackets with a double arc are supplied with aluminum radiators. Such a scheme makes it possible to install batteries on any walls, without restrictions. But the durability of the universal systems is noticeably lower than the custom-made steel corners.
The manufacturer limits the load to one point with a limit of 30 kg. Therefore, before assembling the heating system, you need to recalculate the total weight of the registers. If the battery is too long, then you have to order additional fasteners or use special floor brackets for heating radiators.
When floor brackets are used
The heating system of the house is planned in such a way that the batteries are located along the perimeter of the room, blocking heat losses through window openings, balcony doors, and main walls. But it is not always possible to use walls as a bearing surface for fasteners.
In such cases, floor fasteners are used:
- use of panoramic windows in the room from ceiling to floor;
- if the walls are lined with lightweight materials that cannot be used as a load-bearing base for heating radiators;
- for temporary placement of the heating system.
The latter case is the most common. Overhaul in the room is impossible without a normally functioning heating system. To plaster the walls, you have to remove the heating system. But the plaster will not dry out if the water heating system does not support 18-20 OC throughout the week.
Floor brackets are used for modern cast iron batteries due to their high weight or due to the specific interior of the room. In this case, the fasteners are structurally combined with the supply of the heating system.
How to hang a heating radiator on the brackets
Installation can be started only after the final assembly of the radiator. The finished body will help you determine the anchor points of the hooks.
Determine the drilling points on the wall for the bracket hooks. You can transfer the markup to the wall using a template or through the gap between the registers. We attach it to the wall, note the risks of connecting the pipes of the heating system. The case is best mounted on a temporary stand.
With the help of a building level, you will need to set a drain slope and transfer the line to the wall. We remove the body, on the line we apply the drilling points for the dowels.
We drill holes to a depth of at least 70 mm, hammer in the plugs and wrap the brackets.
It remains only to hang the heating radiator and make sure that the slope of the case corresponds to the previously marked drain line.
Floor mounting of radiators
Before installing the battery on the finished floor bracket, you will need to do a rough floor preparation. The concrete is cleaned with a grinder. It will be necessary to get two perfectly flat "spots" 100x75 mm, otherwise the position of the rack and heating registers will be unstable.
After stripping, we put the fasteners in their places and level them using the building level vertically. Washers should be placed under the support pads, if required. We fix the racks with dowels to the floor. You can hang the case. There is a little thing left - using a hammer and a wooden spacer to knock out the vertical post of each bracket so that the distance to the wall is the same for all attachment points.
We fill in the screed, tighten the fixing bolts, and the pipes can be connected.
Choosing the right bracket for a heating radiator is a guarantee that the heating circuit will not fail or depressurize at the most inopportune moment.
