heat engineering calculation, hydraulic calculation, equipment specification, explanatory note

Heating is artificial heating of premises in order to maintain the temperature at a given level for by compensating for heat losses in them through heating devices.

A home heating system is a complex communication system, the rationality of which determines the amount of future heating costs. If you do not want to overpay for heat, the system design must be developed in detail, professionally and in advance. That is, even before laying the foundation. Designing a house saves up to 15% of funds and up to 20-30% of construction time. If the building is thought out to the smallest detail, you can be sure of its durability, reliability and safety. The latter is especially true when it comes to the heating system.

The heating system, like any other engineering communication, begins with design. Designing a heating system is a complex and time-consuming task. However, our certified specialists have sufficient knowledge of the latest developments and technologies in this area in order to solve it most effectively. At this stage, specialists study in detail the building to be heated, carry out calculations, select equipment and additional components. And all this in order to keep your home warm in any weather, and the budget spent with maximum effect. As a result of their work, you will receive a set of documents with a detailed action plan, instructions, equipment specifications.

We also carry out installation and commissioning of heating systems by partners working on gas, liquid and solid fuels, electricity. All work is carried out taking into account the budget and wishes of the Customer. It can be either a full-fledged project or a part of it (engineering, assembly, sketch). All specialists have rich practical experience (more than 15 years) in the design and installation of heating systems.

Our projects are developed individually for you, taking into account the requirements for the design assignment, project documentation, purchase of equipment and materials, copyright construction supervision to avoid negative consequences, as well as improve performance.

    As a result of design work, you get:
  • An explanatory note that describes in detail the heating system, its components and characteristics. Also, calculations from a specialized program are attached
  • Drawings that include a heating scheme, drawings of the equipment used and its location, as well as service areas and routes, along with piping of nodes in detail
  • Executive documentation includes heating project corrected taking into account the actually mounted system, the final location of its elements


  • Maintaining a comfortable temperature
  • No condensation on outdoor structures
  • Get a high-quality heating system developed by a specialist with many years of experience, so that all design features, physical phenomena and operation features are taken into account;
  • Exclude alterations that inevitably occur during installation without a project;
  • Exclude easy commissioning and search for a responsible specialist for the operation of the system;
  • Get a high-quality technical solution without marketing that will last a long time;
  • Reduce capital costs - the owner buys equipment and consumables that match his housing in terms of productivity, power, and therefore does not overpay;
  • It is easier to choose a contractor. You have an estimate, equipment specification, procedure with deadlines;
  • Easier to buy materials. Designers accurately calculate the volume of building materials, allowing you to save up to 20%;
  • Buy equipment faster. You receive a list of equipment suitable specifically for your home;
  • It is safer to start installation. You know exactly what work and in what time frame, as well as how much money it will take;
  • reduces operating costs - the less and more economically fuel is spent, the less often it will be necessary to maintain lines and equipment;
  • helps to implement a safe and durable system - most often the cause of accidents and failures is due to the system being poorly designed or not designed at all;
  • provides the customer with a comfortable home - designers select the latest equipment and solutions , providing the system with automation and adjustment levers;
  • guarantees safety in cooperation with a third-party contractor - you know exactly how much the installation and commissioning of the system will cost, how much materials and time will be required. It is more difficult to deceive the customer in such a situation.

    Design: components and stages

    The heating system consists of three components: a boiler room, heating devices and a decoupling system connecting them. In order to achieve a coordinated and energy efficient operation of all components, the designer:
    • collects all the initial data for your particular building;
    • calculates the heat loss of a particular building, which depends on the location of the house, materials and other factors ;
    • chooses the source of heat supply, technical solutions of the systems, taking into account safety, construction and operation experience;
    • does hydraulic calculations;
    • determines a profitable heating scheme.
    • li>

    There is no one-size-fits-all solution for a heating circuit. Therefore, designing a system for each specific house is a search for a unique solution.

    1. Calculation of heat losses

    To organize efficient heating, you need to determine where and how much heat the house loses. It depends on the following factors:
    • place of construction;
    • walls - material, structure, thickness, thermal conductivity, specific gravity;
    • roof - material, structure , shape, height, thickness, thermal conductivity, specific gravity;
    • indoor humidity;
    • vapor permeability;
    • heat absorption;
    • heat capacity;
    • cost of insulation and energy resources;
    • foundation and floor - execution materials;
    • glazing - ordinary, double-glazed windows, etc.;
    • ceiling screed and its thickness.

    Of particular importance for calculations is the geometry of the premises, which also contributes to the formation of cold zones and heat loss.

    2. Hydraulic calculations

    The task of hydraulic calculation is to determine the optimal number of heating devices, pipe diameters and balancing valve settings for a particular house. Without calculation, you can install too much or too little equipment and end up either overpaying or freezing.

    When calculating, the designer takes into account:
    • pipeline and underfloor heating materials;
    • length and number of turns of the heating route ;
    • altitude marks;
    • locations of heaters and risers;
    • types of heaters and their features;
    • heat loss along the length pipes;
    • thermal expansion of pipelines;
    • required coolant flow rate and type for each device;
    • regulation requirements and type of fittings;
    • the need for third-party automation;
    • the inertia of the room;
    • the heat capacity of the building;
    • the relative humidity of the heated room;
    • the presence of natural ventilation;
    • safety requirements;
    • location of people's places of residence relative to heating elements;
    • window height;
    • temperature limits for rooms.
    • < /ul>
      This takes into account the diameter of the pipeline, the power of the pumps, coefficient of resistance of the heating system.

      3. Heating circuit:

      • top or bottom supply circuit;
      • vertical or horizontal heating circuit;
      • one- or two-pipe heating circuit;
      • scheme with beam wiring;
      • scheme of dead-end or associated heating.

      The choice is determined by the totality of the characteristics of your home.

      • “Efficient heating, ventilation, air conditioning and heat supply systems”
      • Modern technologies in heating, ventilation and air conditioning, training requirements
