Heating System Renovation and Modernisation in Tallinn

Most Soviet-era apartment blocks and houses were built between the 1960s and 1990s, meaning their heating systems are now 30–60 years old. A system of that age has often outlived its design life and is running far below its optimal state. What are the signs it's time to renovate?

• Radiators heat unevenly or stay cold
• The system makes noise, clicking or gurgling
• Heating bills are unreasonably high
• Frequent leaks or emergencies occur
• The water runs brown or black when the system is drained
• Thermostats don't regulate temperature properly
• The system is older than 30–40 years

Renovating a heating system is a bigger project that needs proper planning. The first stage is always a site visit and system audit — the technician assesses the condition of the existing system, measures parameters and identifies problems. A project and budget are prepared based on this.

The second stage is design — calculating the new system's parameters, choosing the number and output of radiators, and setting pipe routing and diameters. For apartment associations, the design is also agreed with the city and district heating network. For private clients we prepare a simpler but equally thorough design.

The third stage is carrying out the work. Old pipes and radiators are removed, new ones fitted, connected to the substation, and the system is filled, bled and pressure-tested. Finally comes balancing — adjusting each radiator so heat is distributed evenly across the whole property.

A renovated heating system first of all means greater comfort — your home is evenly warm, radiators run quietly, and thermostats let you set the temperature in each room individually. Secondly, heating costs fall significantly — a modern system is often 20–30% more efficient than an old one, delivering a real financial saving every heating season.

Thirdly, your flat or house increases in market value. A renovated heating system is a strong selling point that can add several thousand euros of value to a property. On top of that, you won't need to worry about heating emergencies or unexpected costs for decades.

For apartment associations, renovating the heating system is one of the largest and most important projects they undertake. Toru SOS has long experience of this kind of work. We offer the full package — from the initial audit and design through to execution and after-care. We can also help prepare applications for KredEx grants, which can cover a significant share of renovation costs.

Everything starts with your call or online enquiry. Our dispatcher listens to the problem, assesses how urgent it is, and sends the nearest available technician. In an emergency we head out immediately; for planned work we agree a time that suits you. The technician arrives with the equipment and spare parts needed to sort things out in a single visit wherever possible.

On site we run a first diagnosis, pin down the exact cause of the fault and propose the best solution. We agree the scope and price with you before starting, so you know exactly what you're paying for. Any extra materials or work are always confirmed separately before we proceed.

Once the job is finished we test the system, clean up after ourselves and issue a report. We give you practical advice on further care and, where useful, can offer a maintenance contract with regular preventive check-ups.
