Budget planning for the organization of heating and maintaining its efficiency is one of the priority tasks for the owner. It is the costly part that is the main limitation when choosing equipment and components for heat supply. What is the estimate of the heating system for: installation, crimping, flushing, repair?
Rules for drawing up an estimate for heating service
It is almost impossible to foresee all costs to the ruble when planning heating. But a correctly drawn up estimate for the installation of heating will help determine the approximate amount of costs.
For the correct formation of the list of current expenses, a deep initial analysis and, in some way, marketing research of the market of services and materials are necessary. These activities should begin before the purchase of equipment and components. The estimate for the installation of the heating system includes the following items:
- Consumables and equipment - boiler, expansion tank, circulation pump, pipes, etc .;
- Installation cost - specialist services, home adaptation for heating installation;
- Preparatory work on testing and launching the system - filling with coolant, pressure testing, adjustment of control devices and safety groups.
In fact, the estimated cost of heating a private house will consist of several documents - a description of installation costs, materials (equipment and accessories) as well as services for starting a heat supply. Despite the fact that some of them can be done independently - it is recommended to take into account these costs.
Structurally, a sample of an estimate for heating should consist of the name of expenses, a description of their characteristics and features, cost per unit, amount required and total amount.
For each type of work it is necessary to draw up a separate document. So, the estimate for pressure testing of the heating system will include unique measures that are unique to this procedure. Therefore, it is recommended that you first familiarize yourself with the nuances of drawing up estimates of various types.
For the preparation of estimates, you can use any standard form. It is only important to determine its content - a list of materials and services.
Assembly estimate of heat supply
This selection of accessories for the future heating system is one of the most important. In practice, problems begin even at the stage of selecting the main components of the system - the boiler and radiators.
Trying to save as much as possible, the cheapest models are purchased. Moreover, their nominal characteristics do not correspond to the calculated ones. As a result, this leads to a significant decrease in the efficiency of the system.
How to avoid a similar situation? The costs of organizing heat supply should be correctly calculated. To do this, you need an estimate for the installation of heating and the purchase of components. Its correct compilation is possible only if you follow these recommendations:
- Calculation of heating depending on the current parameters of the building (heat loss), type of energy carrier (gas, solid fuel, diesel, etc.). The required heat supply capacity for each room in the building is also calculated.
- Based on the data obtained, a list of equipment is compiled - a heating boiler, radiators, a safety group (air vent, expansion tank, temperature regulators) and pipelines. The type of the latter largely affects the estimate for the installation of heating.Polymer can be installed independently when steel lines are mounted with the help of specialists.
- Market monitoring is carried out, as a result of which heat supply components that are optimal in cost and technical characteristics are selected.
- The columns of the estimate for the installation of the heating system are filled in: the cost of equipment, transportation costs and installation work.
The accepted samples of estimates for heating can have a different format. The main thing is that it is convenient for the compiler to fill them out and to use them later as the main financial document for procurement planning.
When involving third parties (organizations) in the installation of heating, it is necessary to agree in advance all items of the estimate in order to avoid further inconsistencies both financially and technically.
Estimation of heating system maintenance
What is the difference between the estimate for the repair of the heating system and the document for installation work? First of all, at significantly lower costs. However, in this case, special attention must be paid to the selection of consumables. They must be adapted to the current system. First, an analysis of future repair costs is performed. For this, the area of heat supply failure is determined and materials are selected for its elimination. Unlike estimates for a heating installation, consumables cannot have a large assortment. So, for chemical washing of pipes, it is necessary to use a special liquid, which will be problematic to find an analogue of.
In general, when forming an estimate for repairing a heating system, one should be guided by the following rules:
- The technical and operational parameters of the replaced components must fully correspond to the old ones that have failed. For example, when replacing a piece of plastic pipe, you should choose the same made of the same material and having the same geometric dimensions;
- In addition to the cost of new components, an estimate is made for installing them in heating;
- Be sure to take into account transportation costs and the services of repair specialists.
Often in the repair estimate of heating a private house there are components that are purchased "in reserve". The specialist can identify the “weak” places of heat supply and will advise you to buy the most necessary components to carry out operational repairs.
Estimation of the restoration of the heating system is most often carried out after the repair. For correct completion, a draft version of the document should be kept, in which all services and materials are indicated.
The estimate for flushing pipes and radiators
Cleaning the heat supply from accumulated dirt and limescale should be performed at least once every 3-4 years. It depends on the composition of the coolant and the material of the manufacture of radiator pipes. For steel models, the frequency is less, since a corrosion layer is formed on their inner surface.
Correctly formed estimates for washing the heating directly depend on the selected technology. In chemical cleaning, most of the costs will be a special composition. For a hydraulic system, the cost of flushing the heating must indicate the cost (rent) of the apparatus for performing this work.
The features of filling this type of document include the following:
- Be sure to take into account the costs of analyzing the degree of contamination of the pipeline and radiators. Without this, the estimate for cleaning the heating would not be complete;
- After all preventive measures are completed, the current state of the system is checked;
- Contaminated liquid disposal costs are included. If the work is carried out by a specialized company, this point is most often not indicated in the washing budget for the heat supply of a private house.
A separate category of work is washing the heat exchanger of the boiler. As well as when filling out an estimate for the installation of a heating system, additional costs will include disassembling and assembling the heater. Flushing the heat exchanger with a flow-through method is not recommended.
For greater efficiency, it is necessary to clean the entire heating system, and not its individual parts. This will increase the estimate, but also significantly increase the efficiency of the system.
Pressure test for heating mains
After installation, repair work or before filling the system, it is necessary to pressure test it. Its meaning is to create excess pressure inside the pipes and radiators (1.25 times higher than the nominal) to search for a possible rush and check the tightness of the entire heat supply.
In the estimate for crimping the heating system, the type of work performed must be indicated. It can be carried out hydraulically or by air. It is preferable to choose the first one, since it is easier to identify microcracks or improperly installed fittings with it.
As additional equipment, hydraulic pumps can be included in the estimates for pressure testing the heating system. They can be rented, since the acquisition for autonomous heat supply is impractical.
It must be remembered that the estimate for the installation of the heating system may vary depending on market conditions - a sharp jump in prices for services and goods. But despite this, it remains the main financial document for the installation and repair of heat supply.
