Underfloor heating installation and maintenance in Tallinn

Tallinn Torutööd installs and maintains water and electric underfloor heating in apartments, detached houses and office spaces in Tallinn and Harju County. The work includes the installation of a new heating circuit during construction or renovation, repair of the existing system, replacement of the thermostat and sensor, and balancing of the manifold.

water-based underfloor heating requires a heating circuit cast into the screed and a manifold that mixes the flow of the heating circuit with the return flow for a cooler floor, and electric underfloor heating puts a heating mat or heating cable directly under the tile adhesive or thin screed. In the new developments in Rae municipality and Pirita, water-based underfloor heating is already designed during the construction stage, in Lasnamäe and Mustamäe older fund apartments, an electric solution is suitable, because the leveling of the water circuit raises the floor too high for the existing doorway.

Underfloor heating and related work

The heating mat heats the bathroom tile to 28 degrees in 30 minutes, and the water-based underfloor heating manifold mixes the water going into the floor to 35 degrees. By the end of 2025, 1,318 heating mats and 23,431 m² of water-based underfloor heating had been installed.

  • Electric underfloor heating, the plumber rolls the heating mat on the floor of an empty room, the plumber agrees the time of the installation of the heating mat with the customer's tiler, so that the mat is covered with tile adhesive on the same day.

    Electric underfloor heating

    Electric underfloor heating is installed as a heating mat, the cable loops of which are already attached by the manufacturer to a film-free base in a certain step, or as a loose heating cable, the step of which is determined by the installer according to the heat loss of the room. A cold bathroom requires more cable per square metre than a warm bedroom, because the total power of the cable must cover the heat loss of the entire room, not just the surface of the floor.

    Tallinn Torutööd describes the installation of electric underfloor heating in more detail on the electric underfloor heating page, where there is also a photo of the installation of the cable loops before pouring the screed.

  • Repair of underfloor heating, search for the location of the fault, repair call also follows the replacement of the floor covering, during which the ring pipe has been damaged.

    Underfloor heating repair

    Underfloor heating repair begins with the exact location of the fault: in the case of an electric system, we measure the resistance of the cable and the insulation resistance with a megometer and compare the result with the initial value indicated on the installation card, in the case of a water system, we pressurize the circuit and monitor the pressure drop, which shows in which manifold line the leak is.

    Tallinn Torutööd uses a thermal camera to mark the location of the broken cable on the floor with the accuracy of a credit card, before the tile is even disassembled, so the opening area remains minimal and the tiled surface of the entire bathroom does not have to be touched.

  • Underfloor heating thermostat replacement, the plumber connects the thermostat wires on the living room wall, the programmable thermostat fits the existing wiring, the wall is not opened.

    Underfloor heating thermostat replacement

    Thermostat replacement replaces a mechanical, single-setting thermostat with a digital or app-controlled model that reads the temperature from a sensor inside the floor, not the room air sensor, because only the floor sensor prevents the slab from overheating after the air sensor fails.

    Tallinn Torutööd keeps thermostat models from different manufacturers in the van, so that the sensor left in the floor can be used with the new thermostat, because the socket size and sensor extension of older electric underfloor heating systems differ between manufacturers.

  • water-based underfloor heating, the plumber installs heating pipe circuits next to the manifold, in 2025, 63 percent of new residential premises in Estonia will be completed in Harju County.

    Water-based underfloor heating

    The water-based underfloor heating carries the circuit with a 16 mm PE-RT pipe in step 15 cm in the bathroom and colder corner, 20 cm in the living room and bedroom, connecting all circuits to the manifold of the manifold, where the flow of each circuit can be adjusted separately. The manifold always needs its own circulation pump to ensure circulation, which is a device separate from the usual domestic hot water pump.

    Tallinn Torutööd pressurizes the water-based underfloor heating circuit to 6 bar and monitors the pressure 60 minutes before pouring the screed, because a pipe leak in the screed means cutting the floor open after curing.

Underfloor heating installation prices

The installation of underfloor heating is calculated per square metre, and the price depends on the type of heating and whether the heating mat goes into the tile adhesive or a new screed is poured. The prices below are for the work without the cost of the material, the call-out fee within Tallinn is 7.40 euros.

ServicePrice
Electric underfloor heating mat installationalates 27 € /m²
Water-based underfloor heating with manifoldalates 28 € /m²
Underfloor heating fault finding and repairalates 52 € /h
Replacing the thermostat and floor sensoralates 64 €
Pressure test and reportalates 56 € /h
Call-out within Tallinn7,40 €

The main factors affecting the price:

  • the area and shape of the room: corners and areas under furniture reduce the size of the area that needs cable
  • height limit of screed on the door handle: the height of the screed is not increased when the floor covering is changed
  • removal of the existing floor covering: removing the tile or laminate takes extra time
  • access to the manifold: the manifold installed in the new cabinet adds work to the water-based underfloor heating
  • water-based underfloor heating connected to the general heating circuit of the house requires the consent of the apartment association
  • size of main protection: electric underfloor heating adds heating load to the main protection of the apartment

How long does underfloor heating installation take?

Installing an electric heating mat in one bathroom, 6 m², takes 4 hours: the mat is unrolled, fixed with tile adhesive and tested for resistance before tiling begins. The new tile can be applied the next day, because the glue needs standing time, not the heating circuit. The average area of ​​installed heating mats is 6.2 m².

Installation of water-based underfloor heating in a two-room apartment, 40 m², takes 3 working days: on the first day we run the pipe and connect the manifold, on the second we pressurize and check for leaks, on the third we pour leveling. The heating circuit must be started at full power 21 days after pouring the mold, because a faster start-up will cause painful cracks.

It takes 3 hours to repair one electrical loop, from fault finding to repair, and 5 hours to repair a water loop leak in the middle of the pipe, far from the manifold, because the tile area that can be opened is larger.

Replacing the thermostat and sensor takes 45 minutes. We will respond to the enquiry within two hours on a working day, we will start the measurement and installation within five working days. In Tallinn, the emergency plumber is at the leaking manifold in 45 minutes.

A plumber connects the underfloor heating manifold, in 2025 1,891 m² of water-based underfloor heating were installed.
The living room of a Pirita detached house extension with a light oak imitation floor, high windows and a white distribution cabinet door recessed into the wall, pines visible from the windows, the underfloor heating installer specifies a low thermal resistance underlayment for the customer, which allows the heat of the water-based underfloor heating to pass through the floor covering.

Customer: Siiri N., customer of the addition to Pirita's home. property: Near Pirita Velodrome, Pirita.

1. Inspection and measurement: the heating area of the extension is 40 m², the 7-centimeter leveling pour brings the floor to the same level as the older part of the house, and the house's central heating is the source of heat.

2. Installation and protection: the access path was under a protective film, the 16-mm PE-RT pipe went in a 15-cm step along the 20-cm and cold outer wall in the living room, and the 4 circles got a number on the manifold that coincides with the same number on the floor plan.

3. Testing and handover: the circuit was pressurized to 6 bar and the pressure was maintained for 60 minutes before leveling, and the distance of each circle from the walls was measured on the installation card.

4. Start-up: the first switch-on was 21 days after the pain, the temperature increased by 5 degrees per day, and the manifold mixes the water going into the floor to 35 degrees.

Invoice: water-based underfloor heating installation with manifold, 40 m² × €28; call-out within Tallinn, 3 × €7.40. Total €1,142.20 including VAT; pipe, manifold and leveling casting are not included in the labor price.

Working time: 3 working days for pipe and manifold installation, pressurization, leakage control and leveling casting by the customer's builder; the first switch-on was 21 days after pain (2024, handover report no. 49812).

Result: 40 m² of the extension is heated by 35-degree floor water from the same boiler that heats the older part of the house.

How we work

Three steps from the inquiry to the finished underfloor heating system.

  1. 1. Inspect and measure

    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 heat loss, check the height of the existing floor structure and the space around the door and decide whether the heat source is an electric solution or the house's own heating circuit. The amount of the offer is formed by the square meters of the measured heating surface.

  2. 2. Install and protect

    We cover the access road with a protective film and carefully remove the old floor covering to be recycled. We draw each meter of the electric cable on the installation map before pouring the screed, we mark each circle of the water circuit on the manifold with a number that coincides with the same number on the floor plan.

  3. 3. Test and hand over

    We test the electrical system with a megameter and record the result, pressurize the water circuit and monitor the pressure before casting. The distance of each circle and cable from the walls is measured on the installation map. The work is covered by a 2-year written workmanship warranty.

Choosing an underfloor heating system

The height limit of the room, the purpose of use and the existing heating solution of the house decide whether electric or water-based underfloor heating is suitable.

Electric heating mats and cables

The heating mat is suitable for smaller bathrooms and hallways, where the height of the screed cannot be raised, because the mat fits into a 3-millimeter tile adhesive layer. A loose heating cable is suitable for an irregularly shaped room, where the cable follows the circuit of the furniture or the bath without the cutting residues typical of mats.

Water-based underfloor heating loops and manifold

water-based underfloor heating is suitable for a larger, re-poured floor and a house where the heat source is already a central heating boiler or a district heating substation, because the manifold mixes the hot water from the existing circuit to the lower flow temperature of the underfloor heating. One manifold can accommodate 8 heating circuits, and a second manifold is installed on a larger surface.

Screed drying time and first start-up

A new screed needs 21 days of drying time before starting, and then the temperature must be increased gradually, 5 degrees per day, until the working temperature is reached, not immediately at full power. Starting too fast will create stresses in the cast layer, which will crack it and damage the tiling installed on top.

Frequently asked questions

Can underfloor heating be installed in an older apartment?

Electric underfloor heating is suitable for every apartment in a panel building, because the heating mat only needs 3 mm of installation height. water-based underfloor heating requires that the floor ceiling has enough load-bearing capacity and the apartment remains a separate system from the general outline of the apartment association, which needs its own circulation pump.

How much will the floor level rise?

The electric heating mat raises the floor by 3 mm plus the height of the slab. water-based underfloor heating with screeding will raise the floor by 7 cm, so the free space of the doorway and threshold must be checked before installation.

How much does bathroom underfloor heating cost?

Installation of electric underfloor heating for a 6 square meter bathroom starts at 162 euros, which is 27 euros per square metre. The installation of the thermostat is included in this price, the tiling work is ordered separately.

How much electricity does electric underfloor heating use?

A heating mat for a 6 square meter bathroom consumes 780 watts at full power, and the thermostat only keeps the mat inside part of the time, not continuously. For an entire apartment, electric underfloor heating is expensive as a main heating source, reasonable as additional heat for the bathroom and hallway.

Why does underfloor heating warm unevenly?

Cold spots on the electric floor are caused by an uneven cable step and the area under the furniture, which is correctly left free of cables during installation and therefore appears cold. In the water circuit, uneven heating means a partially blocked circuit of the manifold or air obstructing the flow.

When can heating be switched on after a new screed is laid?

The new screed needs 21 days of drying time before the heating can be switched on at all. The temperature is then gradually increased by 5 degrees per day, so that full power is reached 7 days after the first switch-on.

Can underfloor heating use a standard thermostat?

No, a regular room thermostat only reads the air temperature and lets the floor overheat before it reacts. A thermostat that uses a sensor inside the floor as the main source of control is always suitable for underfloor heating.

Where do you install underfloor heating?

We install underfloor heating throughout Tallinn, both on Lasnamäe, Mustamäe and Õismäe, as well as in Kesklinna, Kalamaja, Nõmme and Pirita, and in the five municipalities of Maardu, Viimsi, Saue, Keila and Rae in the municipality of Harjumaa. In the new development, the water-based underfloor heating pipe is already cast into the screed during the construction stage, during the renovation of the bathroom, the heating mat goes into a 3-millimeter tile adhesive layer. There were 147 underfloor heating jobs in 2025, 81 of them in Tallinn.
