Circulation pump replacement and repair in Tallinn

Tallinn Torutööd replaces and repairs circulation pumps in Tallinn and Harju County apartments, detached houses and apartment association heating units. The work includes replacement of the heating system pump and hot water circulation pump, installation of a booster pump in houses with low water pressure, and pump repair and noise elimination.

The electronic pump of the heating substation of the apartment building changes the rotation speed according to the pressure difference in the circuit, and in older systems a mechanical pump with a step switch jobs. During the summer downtime, scale gets attached to the bearing surface and a pump with a stuck rotor does not start by itself in the fall, therefore we also service the pumps during the summer months.

Circulation pumps and related work

Circulation pump, hot water circulation pump and pressure booster pump are three different devices that move heating water, keep domestic water warm to the tap and increase water pressure. Tallinn Torutööd has performed 3,391 pump jobs by the end of 2025, the circulation pump was replaced 1,987 times.

  • Installation of a hot water circulation pump, the plumber kneels at the pump on the wall next to the gray water heater, at the end of the work, the pump always gets an insulation shell, which reduces heat loss.

    Hot Water Circulation Pump Installation

    The hot water circulation pump keeps the water from the boiler to the tap warm by circulating the water back to the boiler via the return line, so that when you open the tap, you don't have to wait for half a minute, but it's immediately warm. The pump is installed on the return line with a check valve, which prevents water from moving in the wrong direction with the pump standing still.

    Tallinn Torutööd always installs a timer on the circulation pump that turns the pump off at night, because a continuous pump wastes electricity and accelerates boiler water calcification much more than intermittent circulation.

  • Booster pump on concrete base and white diaphragm tank with pressure gauge, the plumber stands by the control block on the wall, after installation, Tallinn Torutööd shows the customer how to reset the pressure switch.

    Booster pump installation

    The pressure booster pump raises the water pressure in houses where the pressure in the pipeline does not reach the top floor sufficiently or the pressure from the well remains weak for the taps. The pump is installed with a diaphragm tank and a pressure switch that starts the pump at a pressure lower than the set limit and stops it when the tank is full.

    Tallinn Torutööd sets the start limit of the booster pump to 2 bar and the stop limit to 3 bar, because a small difference between these two values will turn the pump on and off continuously and shorten the life of the motor.

  • Circulation pump repair, the plumber connects the measuring leads of the multimeter to the pump next to the red expansion tank, in 2025, 71 circulation pumps were replaced in the heating units of the apartment buildings.

    Circulation pump repair

    The repair starts with freeing the rotor: with the screw head on the end of the pump shaft, the stuck rotor can be unscrewed by hand without having to immediately disassemble the pump. A pump stalling after the rotor is released means a worn mechanical seal is letting water into the bearing, or a blown capacitor in the starting circuit of a single-phase motor.

    At the end of the repair, Tallinn Torutööd checks the tightness of the joint with a pressure gauge.

  • Circulation pump replacement, gloved plumber installs red pump between copper pipes under wall-mounted unit, automatic air separator installed next to pump releases trapped air in circuit before it reaches pump.

    Circulation pump replacement

    We replace a pump over 10 years old with a new one instead of repairing it, because the energy class of older pumps with a wet rotor is considerably worse than the new models with electronic regulation. A new pump is always installed with the shaft horizontal and with shut-off valves on both sides, which allows the next maintenance to be performed without draining the circuit.

Circulation pump replacement prices

A pump replaced in the same location is a cheaper job than a pump installed in a new location, and the price is also affected by the type and capacity of the pump. The prices below are for work without the cost of the pump, the call-out fee within Tallinn is 7.40 euros.

ServicePrice
Circulation pump replacementalates 140 €
Installation of a hot water circulation pump with a timeralates 160 €
Installation of a booster pump with a diaphragm tankalates 220 €
Pump repair: seal or capacitoralates 60 €
Pressure test and reportalates 56 € /h
Call-out within Tallinn7,40 €

The main factors affecting the price:

  • pump type and power: the heating substation pump differs from the circulation and booster pump in terms of flow and pressure
  • installation location: the new location requires additional piping and wall mounting, a change is sufficient for the existing location
  • type of electrical connection: a three-phase pump requires a different plug than a single-phase pump
  • old pump condition and sticking: a rotor that has been standing for a long time needs a more forceful release before replacement
  • diaphragm tank at the booster pump: the old rusted tank is replaced with a new one
  • consent of the apartment association for the pump installed in the general circuit of the house, it is not asked for the internal line of the apartment

How long does circulation pump replacement take?

Changing the pump to the same connection takes 1 hour: the circuit line is closed from the shut-off valves, the old pump is removed, the new one is installed in the correct flow direction, and the line is refilled. In a circuit with shut-off valves, the heating circuit in the whole house is not closed.

Installing the hot water circulation pump in a new location near the boiler takes 2 hours, because the check valve installation and the timer setting are added. The installation of the booster pump with the diaphragm tank takes 3 hours, as the tank needs to be fixed and the pressure switch needs to be set in several steps.

Pump repair with rotor release takes 30 minutes, mechanical seal replacement takes 90 minutes. A jammed pump that can be dismantled up to the bearings adds 1 hour to the work.

We will respond to your enquiry within two hours on a working day. The planned pump replacement starts within five working days, and the repairman reaches the stopped pump in Tallinn in 45 minutes.

A bespectacled plumber connects the wires of the green circulation pump on the copper piping, a drip loop is left on the pump power cable so that the condensate dripping from the pipe does not run along the cable to the terminal box.
In the heating substation of the basement of the Mustamäe apartment building, a new circulation pump between two shut-off valves with a blue lever, a plate heat exchanger and pressure gauges behind, a metal sheet and a cloth on the floor, the new pump is selected with the same construction length as the old pump, so that it fits over the old pump without cutting the pipes.

Apartment building heating substation Circulation pump replacement Near Lepistiku Park

Customer: Lembit V., member of the board of the Mustamäe apartment building apartment association, who is responsible for the heating substation. property: Near Lepistiku Park, Mustamäe.

1. Inspection and identification: the model and flow from the data tile showed a 14-year-old three-speed mechanical pump running at the highest speed and echoing in the first-floor apartments, and the more than 10-year-old pump was replaced with a new electronic pump instead of repair.

2. Circuit closure and replacement: the line was closed by the shut-off valves on both sides of the pump, the water in the line was collected in a bucket, and the new pump went to the same place with the shaft horizontally and in the direction of the arrow on the housing, without emptying the heating circuit of the house.

3. Start-up and handover: Flow and pressure were measured at start-up, joints remained dry, and the readings went into the handover report with a 2-year written performance guarantee.

Invoice: Circulation pump replacement, 1 × €140; call-out within Tallinn, 1 × €7.40. Total €147.40 including VAT; the pump is not included in the labor price.

Working time: 1 hour, because the new pump went to the same connection point (2025, handover report no. 52 977).

Result: The pump can no longer be heard in the apartments on the first floor, and the electricity consumption of the new pump is one fifth of that of the old pump.

How we work

Three steps from inquiry to ready pump.

  1. 1. Inspect and identify the pump

    You call or fill out the form at the bottom of the page. On the property, we read the model and flow rate from the pump nameplate, check the installation direction and the presence of shut-off valves. The price of a new pump in the offer is based on the type of pump read from the data tile.

  2. 2. Isolate the circuit and replace the pump

    We close the circuit line at the shut-off valves and collect the water in the line in a bucket before removing the pump. The new pump is installed in the correct direction of flow, which is marked with an arrow on the housing, and the power supply is connected according to the indications on the nameplate.

  3. 3. Start, test and hand over

    We start the pump, check the flow and pressure and make sure that there are no leaks in the connection. We write the flow and pressure readings in the handover report. The work is covered by a 2-year written workmanship warranty.

Choosing a circulation pump

The length of the circuit, the pressure requirement and the method of use decide whether a pump with electronic regulation or a step switch is suitable.

Electronic pump for a heating substation

The electronic pump automatically changes the rotation speed according to the pressure difference in the circuit, which is why it is well suited for an apartment building where the number of radiators and the position of thermostats are constantly changing. It uses 80 percent less electricity than the old heating substation mechanical pump.

Three-speed pump for a small circuit

A stepped pump, where the speed is manually selected between 3 positions, is suitable for a small, constant load circuit of a detached house, where the additional cost of automation does not provide significant savings. It's cheaper and easier to replace than a model filled with electronics.

Booster pump and pressure tank

The booster pump needs a paired membrane tank that keeps the accumulated pressure and prevents the pump from starting too often in case of a small water intake. The size of the tank is chosen according to the largest water intake in the house at one time, a tank that is too small starts the pump as soon as one tap is opened.

Frequently asked questions

Why will the pump not start after summer?

In a stationary pump, scale accumulates on the bearing surface and jams the rotor. At the end of the shaft of a pump with a wet rotor, there is a screw head with which the rotor can be unscrewed by hand without disassembling the pump.

Why is the circulation pump noisy?

A healthy pump cannot be heard over the door, and a loud pump indicates air in the circuit or a speed setting that is too high. On the electronic pump, we reduce the speed so much that the flow remains sufficient for the radiators.

How much does pump replacement cost?

The price of changing a circulation pump with existing connections starts from 140 euros and the work takes 1 hour. The cost of the new pump is added separately and increases with the power of the model.

Does a hot water circulation pump need to run continuously?

No, the timer turns the pump off at night and starts in the morning before the family wakes up. Continuous operation accelerates the calcification of the water in the boiler and unnecessarily increases the electricity bill.

Why is water pressure low only on upper floors?

Each floor takes part of the water pressure due to gravity, and in a house with low mains pressure, too little pressure remains in the taps on the top floor. A pressure booster pump on the house's intake piping restores the pressure on the upper floors.

Does a booster pump need regular maintenance?

We check the precharge pressure of the membrane tank once a year, because it drops over the years and too low precharge pressure turns the pump on and off more often than necessary. A pump working with filtered water does not require any other annual maintenance.

What should I do if the pump is leaking?

Unplug the pump and call. the call-out fee within Tallinn is 7.40 euros, and the plumber will measure the pressure and current consumption of the pump on site. There were 46 emergency calls for a stopped or leaking pump in 2025.

Where do you replace and repair pumps?

We accept orders for pump work from all over Tallinn: Lasnamäe, Mustamäe, Õismäe, Kesklinna, Kalamaja, Nõmme and Pirita, and Harjumaa Maardu, Viimsi, Saue, Keila and Rae parish. We replace pumps in the heating units of apartment buildings and borehole pumps in detached houses. Of the 186 pump jobs in 2025, 118 were in Tallinn and 68 in Harju County.
