Radiator replacement and maintenance in Tallinn

Tallinn Torutööd replaces and maintains radiators in apartments, detached houses and apartment association houses in Tallinn and Harju County. The work includes dismantling the old radiator and installing a new one, connecting the towel dryer to the heating circuit, changing the thermostat valves and flushing and venting the radiators.

In the wooden houses of Kalamaja and Kadrioru, cast iron radiators from the 1930s are still in use, with sections that can be added or removed, and in the apartment buildings, a steel plate radiator with one, two or three panels was installed in the 2000s. We choose the type and size of the new radiator according to the square meters of the room and the area of ​​the window, because a radiator that is too small cannot heat the room air quickly enough in cold weather.

Radiator services and related work

During radiator work, only the line of the radiator being replaced, repaired or washed is closed from the corner valves, not the main valve of the entire apartment. From 2002 to the end of 2025, Tallinn Torutööd replaced 11,482 radiators in 4,418 jobs, or an average of 2.6 radiators per job.

  • Installation of the towel dryer in the bathroom, mounting holes are drilled on the tiled wall with a tile drill and the dryer is placed on four anchors.

    Towel rail installation

    The towel dryer is connected to the bathroom heating circuit with a T-joint and a bypass valve, which allows water to flow even in the summer, when the radiator thermostats are closed elsewhere in the house. The standard size dryer is 500 mm wide and 1200 mm high, can hold 4 towels at the same time and provides enough heat for a 6 square meter bathroom.

    Tallinn Torutööd always connects the towel rail to the angle valves and vent cap, not directly to the rigid piping, so the unit can be removed for later repairs without closing the heating circuit.

  • Radiator repair, the plumber works on the lower connection of the panel radiator above the tray, the thermostat head is always installed horizontally, because the upright head gets caught in the warm air rising from the radiator and closes the valve too early.

    Radiator Repair

    Radiator repair includes sealing the nipple leak between the sections, replacing the valve core and replacing the cracked vent cap. Between the sections of the old cast-iron radiator, a traditional seal with hemp thread and red lead putty goes between the sections, which lasts the nipple for 60 years, on the newer aluminum radiator we use a rubber seal.

    Tallinn Torutööd will keep the cast iron radiator with intact sections during the repair, because the cast iron radiator stays warmer than the steel plate after the heating has stopped and fits the style of the Kadrioru wooden house better than a new steel plate.

  • Flushing the radiators, the hose connected to the radiator valve directs the water into the bucket, the hose is screwed onto the valve by hand, not with pliers, so that the brass thread remains intact.

    Radiator flushing

    Flushing radiators differs from flushing the entire heating system in that the radiator is removed from the heating circuit and rinsed with a pressure washer either in the bathtub or outdoors, which is why the lower part of the radiator, which collects the most mud, is completely cleaned of sediment.

    Tallinn Torutööd gives a 2-year written warranty on the flushed radiator and reassembled connections, which also covers the replacement of an old valve that no longer closes properly even after disassembly.

  • Thermostat valve replacement, the plumber turns the radiator valve with a wrench, the new thermostat heads have a gas-filled sensor and respond accurately to the room temperature.

    Thermostat valve replacement

    A thermostatic valve consists of two parts: the valve body, which remains in the piping, and the thermostatic head, which reads the room temperature and moves the piston inside the body. The piston of the valve, which was not unscrewed in the summer, gets stuck, and in the autumn the radiator does not respond to being turned at all.

    Tallinn Torutööd keeps 4 manufacturers of thermostatic heads in the van because the head mounting mechanism varies by valve body manufacturer and the wrong head won't snap onto the body.

Radiator replacement prices

The price of a radiator replacement depends on the size and material of the radiator and whether the connection remains in the same place or the line is moved. The prices are for the work without the cost of the radiator and fittings, the call-out fee within Tallinn is 7.40 euros.

Radiator replacement, standard sizealates 86 €
Heated towel rail installationalates 100 €
Radiator repair, valve or section repairalates 51 €
Radiator flushing, one radiatoralates 50 €
Thermostat valve replacementalates 51 €
Call-out within Tallinn7,40 €

The main factors affecting the price:

  • radiator type and material: section repair of a cast iron radiator takes more time than replacing a steel plate
  • connection type: a radiator with connection current and a connection coming from below need different fittings
  • removal and disposal of the old radiator when installing a device with a different size
  • suitability of height and width under the window and the location of the existing wall attachment
  • the apartment association's consent, which is required to change the connection to the riser of the house
  • old connection condition: the corroded thread joint gets a new thread cut on site

How long does radiator replacement take?

Changing one radiator at the same connection point takes 90 minutes: the line corresponding to the heating circuit is closed, the old radiator is removed, the new one is lifted onto the wall brackets and connected to the same corner valves. Changing an entire apartment, 5 radiators takes one working day.

The installation of the towel warmer in a new location, where the connection to the heating circuit must be transported, takes 3 hours, because the addition of the installation of the T-joint in the existing pipe and the opening of the wall above the connection point. Towel dryers were connected to the heating circuit in 2025 41.

A section leak repair takes 2 hours and a valve core replacement takes 45 minutes. Sealing a cast iron radiator is more time-consuming than replacing a steel plate valve, as the sections must be separated and the nipples resealed.

Flushing one radiator takes 40 minutes and changing a thermostat valve takes 20 minutes. We will respond to your enquiry within two hours on a working day. The replacement of radiators starts within five working days, and we reach the breakdown in Tallinn within 45 minutes.

How we work

Three steps from inquiry to finished radiator.

  1. 1. Measure the room and window

    You call or fill out the form at the bottom of the page. On the property, we measure the area of ​​the room and the width of the window, check the type of existing connection and whether the corner valves need to be replaced. We prepare a price offer based on the number of radiators and the type of connection.

  2. 2. Shut off water and replace the radiator

    We close the radiator line from the corner valves, not from the main valve of the whole apartment, cover the floor with protective film and empty the radiator into a bucket before removal. The new radiator is mounted on the wall, connected and the case is flushed before filling.

Choosing a radiator

The age of the building, the construction of the wall and the need for heat determine whether a cast iron, steel or aluminum radiator is suitable.

Cast iron radiators in older houses

In Kalamaja and Kadriorg wooden houses built before the war, the cast iron radiator is the best, because it can withstand higher pressure, heats up slowly and retains heat for a long time even after a heating failure. The number of sections can be changed later by adding or removing individual sections without changing the entire radiator.

Steel panel radiators in apartment buildings

In a apartment building, a steel plate radiator is suitable, which responds quickly to the commands of the thermostat and is lighter than a cast iron radiator. The version with one, two or three panels is chosen according to the heat loss of the room, not the width of the window: a room with a greater heat loss gets more panels.

Towel radiators and bypass valves

The towel dryer needs a bypass valve, which keeps the water moving in the heating circuit even in the summer with the radiators turned off the thermostat. Without a bypass, the towel dryer is cold in the summer and the towels do not dry.

Frequently asked questions

How often should radiators be bled?

Radiators are vented once a year, in the fall before the start of the heating season, because the system loses pressure during the summer. The reason for a radiator that is cold on top and warm on the bottom is air accumulated in the upper part of the radiator.

Can a cast iron radiator be repaired?

Yes, we re-seal the leak between the nipples of the radiator with whole sections with hemp thread and red lead putty and this seal will last 60 years. A radiator with a rotten or cracked section is replaced with a new one.

How much does replacing one radiator cost?

The replacement of a standard-sized steel plate radiator for the same joint starts at 86 euros and takes 90 minutes. The new radiator is added to the bill separately and its price increases with the size and number of panels.

Does a towel radiator work when the heating is off in summer?

Yes, a towel dryer connected to a bypass valve is warm in the summer, because the valve keeps the water circulating even in a house with radiators turned off the thermostat. Without a bypass, the towel warmer stays cold in the summer like the rest of the radiators in the heating circuit.

Why is my radiator rattling?

The rattling sound comes from air moving with the water, which clicks inside the radiator, or from a loose wall bracket that allows the radiator to move and knock against the wall as it heats and cools.

What should I do if the radiator valve will not close?

Do not force, a stuck piston will require a valve core replacement, not more force that will break the valve body. Call, the call-out fee within Tallinn is 7.40 euros, and with the new core the radiator will regain its regulation.

Can I change the size of a radiator?

Yes. We measure the distance between the larger radiator connections and add a short extra section to the pipeline for a different distance. For a smaller radiator, before confirming the size, we calculate that it covers the heat loss of the room.

Where do you replace and repair radiators?

We do radiator work all over Tallinn, including Lasnamäe, Mustamäe, Õismäe, Kesklinna, Kalamaja, Nõmme and Pirita, and in homes in Maardu, Viimsi, Saue, Keila and Rae parishes in Harjumaa. We replace steel plate radiators in apartment building apartments, and repair cast iron radiators in wooden houses. 297 of the radiator jobs were done in 2025 in Tallinn apartments and houses, there were 412 of them in total.
