Step -by -step instructions for replacing heating radiators of various connections

Reducing energy costs and preserving comfort in your home depend on having an efficient heating system. The state of your heating radiators is one important component of this. Radiators may lose their efficiency over time as a result of corrosion, leaks, or just age. Your heating system’s efficiency can be significantly increased by replacing them. We’ll help you improve the efficiency of your home’s heating system by taking you step-by-step through the process of replacing heating radiators with various connections in this guide.

It’s important to evaluate your current heating system and identify the type of radiators you have before starting the replacement process. Different connection types are available for radiators, including thermostatic valves, standard valves, and even more advanced smart heating systems. You can choose the right replacement units and make sure they work with your current setup by being aware of the connections your radiators use.

After determining the kind of radiators you currently own and choosing appropriate substitutes, it’s time to get ready for installation. To commence, assemble all required equipment and supplies, such as a new radiator valve or fitting, pipe wrench, adjustable spanner, pipe cutter, PTFE tape, and radiator key. Preparing everything ahead of time will help to minimize any potential delays and streamline the replacement process.

It is imperative to turn off the central heating system and empty the water from the radiator and surrounding pipes prior to removing the old radiator. In order to avoid water leaks and guarantee a seamless replacement procedure, this step is essential. Be sure to store a bucket or towels underneath the radiator to collect any leftover water and shield your floors from harm.

It’s time to take the old radiator out of the wall after draining and unplugging it from the heating system. To loosen the fittings connecting the radiator to the pipes, you might need to use an adjustable spanner or pipe wrench, depending on the type of connections. After the radiator is loose, carefully remove it from its brackets and set it aside.

It’s time to install the new radiator now that the old one has been removed. Make sure the new radiator valves or fittings are securely fastened to the radiator before proceeding. Next, using the proper fittings, carefully place the radiator on its brackets and attach it to the pipes once more. To prevent breaking the pipes or fittings, take care not to overtighten the connections.

It’s time to add water to the heating system and bleed the radiators to release any trapped air after the new radiator is firmly installed. Restart the central heating system and inspect the recently installed radiator for leaks or problems. Your new radiators will provide effective heating for many years to come with proper installation and maintenance, guaranteeing a cozy and warm home.

Step	Instructions
1	Turn off the heating system and allow radiators to cool.
2	Place towels or buckets under the radiator to catch any water.
3	Use a radiator key to bleed the air out of the radiator.
4	Measure the distance between the pipe connections.
5	Turn off the valves on both sides of the radiator.
6	Use an adjustable wrench to loosen the nuts connecting the radiator to the pipes.
7	Remove the old radiator carefully.
8	Fit the new radiator in place, making sure it aligns with the pipe connections.
9	Use thread seal tape on the threads of the valve connections.
10	Tighten the nuts securely to attach the new radiator to the pipes.
11	Open the valves and check for any leaks.
12	Bleed the radiator again to remove any air trapped inside.

What is to be done

The replacement work procedure can be broken down into six simple steps:

1. Devastation of the heating system.
2. Dismantling of old batteries.
3. Preparation of pipes for connecting a new radiator is a new -thread cut or an extension of the old carvings.
4. Installation of cutting cranes.
5. Battery connection and checking the tightness of the joints.
6. Radiator launch into operation: air descent, adjusting thermostat.

It will be necessary to replace heating radiators with cranes that overlap the coolant’s inflow and outflow in order to save labor costs and time (see photo below).

This situation allows the work to be completed without the need for water descent from the heating system. It is simple to empty the 200–400 ml of coolant that is intended for the radiator section into the replacement.

What time of the year is better to change batteries

Replacing a battery can take anywhere from 10 minutes to 4 hours.

In a private residence, the season cannot be taken into consideration if all the necessary supplies are bought and everything is ready. Even in extreme frost, turning on the heating for one to two hours won’t compromise comfort.

Select late spring or early autumn to replace the radiator in an apartment building without having to cut cranes. During heating season, the riser is turned off completely. Management firms are hesitant to take this action because even a brief disconnect will be met with complaints from the entrance’s occupants, particularly for basic issues that might need to be recalculated.

The likelihood of a hydraulic boat, which could cause an accident in any apartment and flood nearby properties, is another concern following the restoration of the heat supply (filling the system), for which the Criminal Code will also bear liability. Some apartments are left unattended during business hours, which can have unpleasant outcomes because it is impossible to find out in a timely manner.

Public utilities test the system as part of their preventive maintenance during the summer, which could make the replacement process more difficult because coolant deliveries can occur without warning and during a resident’s absence. Summer is a popular time for vacations, and battery replacement may cost more during this period.

In conclusion, work is completed in a private residence as needed; in an apartment, work is completed in May–June or August–September. With cutting taps, you can work whenever you want.

In our guide on replacing heating radiators, we"ve broken down the process into easy steps to help you tackle this task with confidence. Whether you"re dealing with radiators of different connections like screw-threaded, compression, or push-fit, we"ve got you covered. From gathering the right tools to draining your system and removing the old radiator, we walk you through each stage. We"ll also show you how to measure for a new radiator, choose the right size, and install it securely. With clear instructions and helpful tips, you"ll be able to upgrade your heating system efficiently and effectively, ensuring a warmer and more comfortable home for you and your family.

Preparatory work

It is best to complete any task as quickly as possible, but this is only achievable with careful planning.

If the battery needs to be changed beforehand:

• coordinate the date of work with the masters and the management company;
• buy radiators suitable in design;
• Prepare tools and consumables: drives, fittings, taps, thermostats, working tools.

Selecting the appropriate parts for the impending operating conditions is crucial.

The choice of radiators

A private home’s typical heating system is built to a maximum pressure of three atm, rarely higher.

The protective valve will activate when this threshold is reached (the number three bar is visible on the lid). Because of this, practically all of the radiators that are on the market are appropriate for specific systems.

Radiators made of steel, bimetallic, or cast iron are available for apartment buildings with up to seven or eight storeys. Even for five stages, aluminum products are unsuitable—the coolant in centralized networks isn’t right for these kinds of devices. Bimetallic radiators are a better option for homes higher than nine stories, where the system pressure is significantly higher and aluminum, cast iron, and some types of steel convectors are not suitable.

In this scenario, the diagonal connection diagram accounts for the center distance, so there is no need to modify the current pipes.

The center distance in apartment building wiring is typically 300, 350, or 500 mm. That’s why radiators get acquired.

In any other scenario, they take note of the old and new radiators’ dimensions to enable the proper placement of pipes.

How to pick the best models, selection criteria, and steel heating radiators

Necessary tools and consumables

The type of old and new convectors, as well as the connection method, determine the set of devices needed for the task.

They might require:

	lever key, for unscrewing/ twisting of large nuts, as well as to hold the steel pipe, if you need to cut a new thread
	An angle grinding machine (grinder) for cutting pipes from the battery, which could not be dismantled by unscrewing the nuts
	ratchet stroke with a dick of the required diameter for cutting threads on steel pipes
	The gas welding machine, if it is necessary to weld the angles and the drives of metal pipes
	punch for installing brackets
	laser or bubble level
	Roulette, pencil
	Flat container for collecting coolant

To install, obtain:

• plumbing flax (recommended) or sealing tape (FUM) and plumbing paste (optional);
• gaskets of the right size.

Products required for installation, based on the type of radiator:

Crucial! The coolant flow cannot be changed with conventional ball valves. Only fully open or closed positions are intended for them to function.

Step -by -step instructions for replacing the radiator

The following are two algorithms: the simplest and most complex of those that you can encounter.

Replacement of radiators in the presence of cutting cranes

Installing cranes or thermostats with an American thermostat in front of the radiator on both pipes is the simplest solution, taking no more than 20 minutes.

Procedure of operation:

1. Overlapping the taps.
2. We substitute a container under the lower crane, spread a rag to the floor.
3. Open the crane of Maevsky, located in the upper part of the radiator (if any).
4. The lever key is gradually unscrewing the lower connection.
5. We drain the coolant from the battery – in each section there is from 170 to 400 ml of liquid. Based on this volume, the capacity should be prepared.
6. We disconnect the radiator completely.
7. We collect a new battery, install plugs, threaded bushings (adapters) and the crane of Maevsky.
8. Without installing new gaskets, we attach a new radiator. We emphasize the device – it is not allowed to hang the battery with emphasis only on pipes.
9. We mark the brackets (approx. Ed. Immediately about the correct marking and installation of the radiator on the bracket), if they are required to replace them.
10. We mount the brackets.
11. Having hung a radiator, we check the horizontal installation of its installation.
12. Using new gaskets for an American, we fasten a new convector. It is not necessary to apply excessive efforts when twisting – after the unexpected nut has completely embarked in the working position, we turn it by ½-3/4 turns.
13. Open the feed taps and check the presence of leaks. The item is suitable for private and apartment buildings during heating. If the radiators in a high -rise building changed in the summer, then it is better to leave the taps closed. The heat carrier is supplied and the system is checked in the daytime and if the hosts are not at home, and the connections are leaky, the neighbors will be flooded.
14. We release air from the radiator using the crane of Maevsky.

If the work was done during the summer, we open the taps, check the tightness, and lower the air on the day of crimping (you can find out about this from advertisements in the entrances or the Criminal Code).Once the heating system is operating, the same procedures need to be followed.

About marking and mounting scheme

You simply cannot hang the radiators on the supply pipes because of their substantial mass caused by the material and the coolant that is circulating. Brackets are used to install devices on the wall; cast iron models occasionally have legs for floor installation.

Expert builders advise fastening convectors up to eight sections using two brackets placed beneath the upper manifold. Increase the number of supports from the calculation if there are more sections: one bracket for every five sections. Furthermore, it is advised to install hooks at the radiator’s base.

By doing this, you can totally eliminate vibration from the coolant flow and increase the radiators’ operating lifespan.

Levels are used to mark the location after changing a single battery. It is advised to create a template when replacing multiple radiators as this will make the task much easier and save installation time. The video demonstrates how to do this:

Replacing old radiators

It may not be possible to remove outdated cast-iron radiators that are attached to a steel pipeline without causing harm to the eyeliner.

In this instance, the replacement will require locksmith expertise and could take several hours.

The following is the algorithm:

1. We drain water from the riser, in an apartment building it is imperative to contact the management company – the work is carried out by regular locksmiths by order of the main engineer of the enterprise. The work is paid and, depending on the region, it can cost from 200 to 1,200 rubles per riser.
2. Prepare a plum container and rags.
3. Trying to unscrew the counter -players and sleeve without damaging the pipeline.
4. If necessary, dismantle the battery, cutting the pipes with a grinder.
5. We cut a new thread on the pipe of the required length by a dwarf with a rattle. We steal cutting taps or thermoregulator into the finished thread.
6. Try on the battery, make markings, fasten the brackets.
7. We fasten the radiator, check the leaks (if possible).
8. We paint the pipe segments.

The procedure is also the same: trial start, fainting.

Other cutting thread techniques exist for repairing connecting points.

1. Private the drive gas welding.
2. In private houses, use a coupling with an rearrangement to the pipe – a gobo coupling (see. photo below). Devices are produced for pipes of different diameters with internal or external threads. Product price from 600 rubles.

Crucial! The assault cannot be welded using electric welding. In high-pressure, multi-story buildings, corrosion is rapidly forming at joint locations. A connection of this kind may last for one to two years before a leak appears.

How to use flax correctly

Plumb linen is used as a seal when attaching the crane to the steel pipe’s thread.

The process to collaborate with him is as follows:

1. A file or a small triangular file, make notes on the thread (see. photo below). On purchased details, such notes are made by a factory way.
2. Clean the thread of dirt and ward using a metal root.
3. We determine the direction of the thread.
4. We apply a thin layer of plumbing paste.
5. We separate a strand 30–35 cm long from the total skein of flax, this is enough for carving up to 1 inch, straighten the segment into a flat strip.
6. Press the lin with your finger to the drill and wrap the segment in the direction of the thread with a single strand.
7. We seal the winding with your fingers.
8. We apply a thin layer of pasta.
9. We steal the necessary part to the thread.

You can use FUM tape; it has a ten-year lifespan in low pressure networks. However, flax winding is preferable for high-rise buildings.

While replacing outdated radiators in your home may seem like a difficult undertaking, it can actually be a rewarding and manageable upgrade to your heating system. You can increase the comfort and efficiency of your living area and possibly save energy costs by following step-by-step instructions designed for different radiator connections.

Getting all the equipment and supplies needed is essential before beginning the replacement process. This includes pipe fittings, wrenches, pipe sealant, new radiators that work with your heating system, and a level. Making sure you have everything you need in advance will expedite the procedure and reduce interruptions.

To avoid spills and leaks, start by turning off the central heating system and emptying the existing radiators. After the old radiators have been drained, carefully disconnect them from the pipes, making note of their connections and locations. To prevent breaking pipes or creating leaks, this step demands close attention to detail.

It’s now time to install the new radiators after the old ones have been removed. Make sure the brackets or mounting hardware are level and firmly fixed before beginning to attach them to the wall at the designated spots. Next, using the proper fittings, attach the new radiators to the existing pipes. Be sure to use pipe sealant to stop leaks.

Once the new radiators are connected, add more water to the heating system and inspect it for any problems or leaks. You can switch the heating system back on and take advantage of the newly installed radiators’ enhanced warmth and efficiency after everything is verified to be in working order. To guarantee optimal performance and release any trapped air, don’t forget to bleed the radiators if needed.

In conclusion, with the correct direction and planning, replacing heating radiators with different connections is a do-it-yourself project that is manageable. You can improve the efficiency and comfort of your home’s heating system by following these step-by-step instructions. Pay close attention to the details and make the right decisions, and you’ll soon enjoy a more comfortable and energy-efficient living environment.
