Modernization of central heating installations in multi-family buildings is a complex challenge that requires consideration of specific legal, technical, and financial constraints. At Onninen, as a leader in installation solutions, we support property managers and housing cooperatives every day in implementing such projects. Our years of experience show that a properly planned modernization can yield energy savings of up to 30%, while also improving the comfort of residents.
Contemporary multi-family buildings from the 60s to 80s mostly feature two-pipe open system installations with hydraulic regulation using throttling valves. They are characterized by low operational efficiency and a lack of individual cost accounting for heating. Our experience indicates that the key to success is a systematic approach and the use of modern installation technology solutions that we offer in our assortment.

Main constraints in the modernization of heating installations in buildings
Modernization of heating installations in multi-family buildings faces a number of technical and legal constraints that must be considered at the planning stage. As a provider of comprehensive installation solutions, we know that each of these constraints requires an individual approach.
Legal and administrative constraints
According to construction law, modernization of the heating installation in the common part of the building requires the consent of the housing community or the cooperative board. Our experience shows that the process of obtaining the necessary approvals can take from 3 to 6 months. It is also crucial to comply with regulations regarding interference with vertical installation pipes, which are part of the common property.
- Requirement to obtain the community's consent for interference with the heating installation
- Obligation to notify the administrator about planned works
- Compliance with health and safety regulations during work in inhabited buildings
- Adherence to noise standards - work can only be carried out between 6:00 AM and 10:00 PM
Technical barriers related to the building's structure
Large-panel buildings are characterized by limited access to installations, which often run through technological ducts. In our practice, we often encounter situations where access to vertical pipes requires partial dismantling of wall coverings.
| Type of constraint | Problem description | Onninen solution |
|---|---|---|
| Ducts in walls | Difficult access to pipes | Technical endoscopes, planning alternative routes |
| Panel construction | Inability to freely run new routes | Utilization of existing shafts, surface-mounted systems |
| Height of apartments | Limited space under the ceiling | Compact heating solutions, panel radiators |
Costs of modernizing heating installations - economic analysis
Planning the costs of modernizing central heating installations requires a thorough economic analysis. In our experience, the cost of comprehensive modernization of the heating installation in a multi-family building ranges from 3000 to 8000 PLN per apartment, depending on the scope of work and the technical solutions used.
Cost structure of modernization
Based on the implementation of hundreds of modernization projects, we have prepared a summary of typical costs that will help in planning the investment budget:
- Replacement of vertical and distribution pipes: 35-40% of the total cost
- Modernization of the heat node: 20-25% of the project budget
- Installation of regulating and thermostatic valves: 15-20% of costs
- Hydraulic balancing of the installation: 10-15% of expenses
- Design work and technical supervision: 8-12% of the budget
Available funding sources
Building managers can take advantage of several funding programs for the modernization of heating installations. We offer comprehensive support in preparing application documentation for programs such as:
- BGK Thermomodernization Program - grants up to 26% of eligible costs
- European funds - financing up to 85% of costs under regional programs
- Stop Smog Program - funding for the replacement of heat sources
- Local municipal programs - additional financial support
Modern technical solutions in heating modernization
Contemporary modernization of heating installations in multi-family buildings is based on advanced technical solutions that ensure high energy efficiency while maintaining user comfort. In our offer, you will find complete systems that allow for the implementation of even the most demanding projects.
Automatic balancing valves - the heart of modern installations
A key element of modernization is automatic balancing valves, which ensure optimal flow of the heating medium throughout the installation. Thanks to years of cooperation with renowned manufacturers, we offer solutions that eliminate the problem of uneven heating of rooms in the building.
- ASV-PV + ASV-BD valves at the base of residential risers
- Automatic multifunctional AB-QT valves on stairwell risers
- Pressure differential regulators for stable system operation
- Dynamic radiator valves RA-DV with precise regulation
Regulation and automation systems
Modern heating installations require advanced control systems that adjust the operation of heating to the actual needs of the building. We recommend solutions that allow for:
| Regulation system | Advantages of the solution | Energy savings |
|---|---|---|
| Weather regulation | Advantages of the solution | 15-20% |
| Thermostatic radiator valves | Individual regulation in rooms | 20-25% |
| Cost allocators | Settlement according to actual consumption | 10-15% |
| Heat node automation | Optimization of the operating parameters of the entire system | 25-30% |

Frequently asked questions
1. Can the heating installation be modernized in stages, apartment by apartment?
Partial modernization is possible but not very effective. In our experience, the best results come from comprehensive modernization of the entire installation, covering all apartments at once. This allows for optimal hydraulic balancing and achieving maximum energy savings.
2. How long does the modernization of the heating installation in a multi-family building take?
A typical modernization takes from 6 to 12 weeks. The duration depends on the size of the building, the scope of work, and technical conditions. The preparation and design phase additionally takes 4-8 weeks. We offer a detailed work schedule tailored to the specifics of each facility.
3. What are the main benefits of modernizing the central heating installation?
Modernization brings 25-35% savings in heating costs. Additionally, residents gain the ability to individually regulate temperature, uniform heating of all rooms, and settlement according to actual heat consumption. Modern systems also eliminate noise and installation failures.
- Significant reduction in heating bills
- Improvement of thermal comfort in apartments
- Individual accounting of heating costs
- Increase in property value
4. Does the modernization of the heating installation require shutting down heating for the entire duration of the work?
No, we plan the work while maintaining heating continuity. We use a phased work method, where individual sections of the installation are modernized sequentially. This way, residents do not lose access to heat throughout the investment period, and the work is only local.
5. What documents are needed to start the modernization of the heating installation?
The basis is the resolution of the housing community and the technical project. Additionally required are: notification of works to the construction supervision, permissions from the building administrator, energy documentation, and agreements with the heat supplier. We offer comprehensive support in preparing all necessary documents.
6. Can old radiators be used in the modernized installation?
Yes, functional radiators can be retained after appropriate modernization. However, it is necessary to equip them with modern thermostatic valves and conduct thorough internal cleaning. Our experience shows that properly modernized old radiators can work efficiently with modern control systems.
