Heating work reception: essential checks and tests to be carried out
In the field of construction and renovation, the acceptance of heating work is of paramount importance. This act marks not only the completion of a construction site but also guarantees the quality of installations and protects the rights of the project owner. Many are unaware that the acceptance of work is a key moment to formalize the transition between the contractor and the client, far beyond a simple act of acceptance. In this article, we will explore in depth the different forms of work acceptance, the essential checks to carry out, as well as the mandatory tests to ensure the proper functioning of the heating systems installed. Whether you have called upon recognized brands such as De Dietrich, Viessmann, or Chaffoteaux, it is imperative to follow these steps and comply with legal and technical obligations in your acceptance process.
Acceptance of work: definition and issues
The acceptance of heating work is much more than a simple moment of validation. It is governed by legal texts, and in 1978, the law concerning liability and insurance in the construction field clearly established what acceptance is: “the act by which the project owner declares to accept the work with or without reservations.” This act, which comes from the project owner, marks the official end of the construction site and allows for the transfer of custody of the installations.
It should be emphasized that acceptance should not be seen as a relinquishment of rights. On the contrary, it opens the way for recourse and guarantees for the project owner against the contractor in case of defects or major problems.
The importance of acceptance
In a heating project, acceptance is a crucial moment for several reasons:
Validation of work: It attests that the heating installations comply with current standards.
Activates guarantees: Acceptance allows the initiation of legal guarantees, notably the guarantee of perfect completion.
Legal protection: In case of disputes, acceptance acts as proof of the conditions of acceptance of the work carried out.
Confidence in the work: It fosters the establishment of a relationship of trust between the project owner and the contractor.
Types of acceptance of heating work
The acceptance of work can take different forms. Each presents its specificities and modalities, and it is important to know which one to apply according to the context of the construction site.
Friendly acceptance
Friendly acceptance is the most common form. It occurs when the project owner and the contractor agree on the proper execution of the work. The key phases are:
Initiative: Often, it is the contractor who proposes this step. However, the project owner can take the initiative.
Timing of acceptance: Generally, this occurs when all the work is completed, although exceptions may be possible.
Formalization: Acceptance must be recorded in a minutes signed by both parties.
Example: If you had underfloor heating installed by Ferroli, a friendly acceptance will allow you to verify that all components meet your expectations before signing the final document.
Tacit acceptance
Tacit acceptance arises from case law. It may occur when the project owner takes possession of the work without explicitly expressing their acceptance, often after full payment. This indicates a clear intention to accept the work.
It should be noted that if there are reservations about the work, tacit acceptance is not applicable. Thus, for a heating system of the brand Atlantic encountered with defects, tacit acceptance could not be considered.
Judicial acceptance
If neither of the two previous forms is feasible, judicial acceptance becomes an alternative. It is requested by the project owner or the contractor through judicial means, generally in case of refusal of acceptance by one of the parties.
This requires proving that the work is in a state to be accepted, and it also allows for maintaining rights, even if the contractor faces financial difficulties or if the site is abandoned.
Essential checks during work acceptance
Before proceeding to the acceptance of heating work, a number of checks must be systematically performed. This will ensure that the installed system is compliant and operational.
Control of installations
Here are the main points to check:
Compliance of equipment: Ensure that all devices, whether a Viessmann boiler, an Ariston water heater, or another system, are well installed according to the manufacturer's specifications.
Functioning: Test each element to ensure its proper functioning, from boilers to radiators to connected thermostats.
Energy efficiency: Validate that the devices comply with current energy efficiency standards.
It is advisable to apply a four-step control model: observation, functional testing, validation of energy efficiency, and visual inspections. This will help you identify potential defects or areas for improvement.
Tests to be performed on heating installations
During acceptance, certain in-situ tests are also essential:
Check the energy tariff and the efficiency of the boiler.
Perform pressure tests on the heating circuit to verify the tightness of the pipes.
Check the supply and return temperatures to ensure that the heating network is functioning correctly.
A feedback on these tests will allow you to compile all necessary information to anticipate potential future breakdowns.
The acceptance report: a key document
The acceptance report is a fundamental document that formalizes the acceptance of the completed work. It must be prepared in as many copies as there are signing parties, usually two: one for the contractor and one for the project owner.
Content of the acceptance report
For its drafting, it is important to include:
Identity of the parties: Specify the names and addresses of the project owner and the contractor.
Description of the work: Indicate the work carried out, and the specific installations made, such as underfloor heating or a direct heating circuit.
Reservations: Mention all reservations made at the time of acceptance.
Assessment of the work: Note the general state of the installation and whether it meets expectations.
Example: An acceptance report for a Bosch heating installation should include the acceptance date, reservations on non-compliant installations, and a section on the overall functioning.
Beyond the acceptance report: other obligations
It is crucial to understand that even with a compliant acceptance report, there are still several obligations regarding the completed site:
Obtain construction damage insurance before starting the site.
Make reservations on any non-compliant aspect or defect noticed.
Conduct regular follow-ups to anticipate any potential breakdowns.
FAQ on the acceptance of heating work
