The constant use of technical and regulatory documentation of GOST and SNiP is an integral part of the work of engineers, designers, estimators and installers. After all, the compliance of the project with approved state standards and building codes is the key to successful and high-quality work performed and, as a result, the presence of satisfied customers.

For a company specializing in the installation of heating systems, GOST and SNiP regarding heating should become handbooks. No project can be handed over without compliance with building standards. These documents reflect all the requirements for heating systems, provide methods for calculating heat supply and consumable materials, and quality standards for equipment.

The main purpose of these documents is to protect citizens when using construction sites in terms of fire, sanitary and environmental safety, as well as compliance with the requirements for reliability and energy saving for heat supply systems.

Ignoring GOST, SNiP, SP, GESN and VSN standards, building rules and regulations when performing work can lead to unexpected disastrous results. A heating system calculated and installed without taking into account regulatory documents can lead to insufficient thermal conductivity of the system, failure of heating equipment, smoke in rooms or high heating costs due to inefficiency of its operation. Accurate execution of the regulations of the document, which determines the procedure and methods for performing work, will help to avoid failures and breakdowns, as well as further unpleasant proceedings with the customer.

Regulatory documents such as GOST and SNiP, collected in one place, will greatly facilitate the work of the company when performing work on calculations and installing heating systems.
