is there a benefit and how to arrange?

6 min

Have you chosen water heating for your home and firmly decided to arrange it yourself? There is a lot of information on this issue. But to structure and process it in order to understand how to properly arrange water heating with your own hands can become a separate task, slightly inferior to the work on the heating device itself. We hope this article will clarify and help you independently arrange water heating in your home.

Let’s start with the pros that this option has:

  1. Cost savings. But when calculating the financial benefit, be sure to take into account the time spent on installing the heating system, which, perhaps, you could sell at a higher price, and the cost of the tools needed to perform the installation work.

  2. You do it for yourself, which means, conscientiously with the highest possible quality. Of course, it should not be lower than a certain level to ensure long-term operation of the system.
  3. Water convectors JagaYour opinion on what kind of water heating system you should have will not be influenced by the opinion of the contractor, who is interested in doing everything as he is familiar and more convenient, using familiar technologies and devices. But there are new items that are more economical and more convenient to use! For example, we recommend using Jaga water convectors with Low-H20 technology, which allows the heater to reach operating temperature in 10 minutes! A cast iron battery, for reference, heats up in at least an hour.

Therefore, it is advisable to perform water heating with your own hands when:

  • it is profitable to do it yourself, taking into account all the above factors;
  • have the skills for the job.

Let us dwell on the last point in more detail.

Skills and tools required for self-installation of hot water heating

All work on the installation of a water heating system can be reduced to several works:

  1. Installation of a water heating boiler (if an autonomous heating system is being created).
  2. Installation of heating radiators.
  3. Installation of heating system pipes – connection between themselves and with other elements of the system (radiators and boiler).
  4. Installation of fittings (manifolds, valves, air vents, filters, etc.)

Installation of a water heating boiler

double-circuit gas boilerDepending on the model, the boiler can be installed on the floor (floor type) or wall, it is necessary to create a concrete screed 3-5 cm thick. Therefore, the simplest skills of performing concrete work are required. From tools and accessories you will need:

  • container for concrete solution (bucket, basin);
  • rule for surface smoothing;
  • level to check the levelness of the surface (the latter is very important!)

In the case of a wall-mounted boiler, the work is reduced to drilling holes for anchoring fasteners. The required tool is as follows:

  • tape measure for marking the boiler mounting points;
  • hammer drill with a set of drills;

  • plumb line or level to check the verticality of the boiler installation.

Installation of heating radiators

Steel tubular radiatorsThe installation of these heaters consists of the following works:

  • installation on a radiator of a Mayevsky crane (for bleeding air), through plugs, American women, plugs.
  • drilling holes for mounting the radiator on the wall.

This work requires:

  • linen or fum tape (for sealing a threaded connection);
  • a set of keys or an adjustable wrench;
  • tape measure for marking the mounting points of the heater;
  • hammer drill with a set of drills.

The basic skills for installing radiators boil down to the need to correctly install and adjust the hydraulic fittings, the ability to properly reel flax or fum and work with a hammer drill.

Installation of heating pipes

choose polypropylene pipesThere are several types of pipes and methods of their installation, which determine the necessary skills and tools for installation.

A. Plastic pipes

They are connected to each other or to heating radiators using:

  • welding;
  • compression fittings.

If you want to arrange water heating with your own hands, pay attention to the fact that in the first case you need special equipment – for cleaning pipe joints and welding directly. For the second type of connections, no equipment is required, but special fittings must be purchased. Therefore, if you do not have enough skills in working with welding equipment (which you need to get somewhere else), choose a simpler connection option.

B. Reinforced-plastic pipes

These pipes are connected using:

  • press fittings;
  • compression fittings

To carry out these works, you need a pipe cutter, a beveller (for removing plastic to a layer of aluminum foil), a pipe bender, a press tool and pliers (for mounting press fittings). Accordingly, skills in working with these devices are required.

B. Steel pipes

They are connected to each other using either a threaded connection (couplings, angles, tees are used), or by welding. In the first case, skills are required for sealing a threaded connection, in the second, experience with a gas burner. If you have never held it in your hands, this option is definitely not for you.

Concealed pipe routing

This option involves chipping the walls for laying pipes in them. The work does not require great qualifications, but a powerful (at least one kilowatt) angle grinder (“grinder”) and circles for cutting on concrete or brick, depending on the type of walls, are needed.

Sequence of work

At least half the success of any work depends on a clear plan for its implementation. And do-it-yourself water heating is no exception. Regarding the independent creation of heating, the sequence of work is as follows:

  1. System design. It is necessary to choose the optimal scheme, taking into account preferences, opportunities and objective conditions. It is possible that at this stage it will be decided to leave some elements of the old system, for example, heating radiators. Of course, it will be difficult for a non-professional to perform thermal and hydraulic calculations, but there are empirical formulas, according to which it is quite accurately possible to calculate the boiler power and the number of radiators, based on their type.

  2. Obtaining permits from state bodies for the installation of a heating system (in the case of its autonomous version).

  3. Purchase of the necessary components for the new system.

  4. Dismantling of elements of the old hot water heating system.

  5. Boiler installation.

  6. Installation of the expansion tank and circulation pump (if they are not included in the boiler package).

  7. Installation of heating radiators.

  8. Boiler and radiator piping, installation of the necessary fittings.

  9. Connecting the boiler to the gas system, in the case of installing a gas boiler (performed by specialists of the gas industry).

  10. Commissioning works.

DIY water heating. Typical mistakes

  1. A boiler of the wrong capacity was selected. This usually happens when the boiler power is selected end-to-end, without taking into account a number of factors – the presence of an additional external wall (in corner apartments), the lack of thermal insulation (for example, for a non-insulated house, 130-300 W / m2 is required, and for a thermally insulated house with modern windows – only up to 70 W / m2), the apartment is on the first or last floor, etc.
    How to avoid mistakes – make a careful calculation, taking into account all factors. Detailed information about them can be easily found on the Internet.

  2. Insufficient chimney height. As a result, there is not enough traction, and the boiler automation turns it off.
    How to avoid mistakes – choose the right chimney length. For a gas boiler, this is at least 4 meters, for the rest – 5 meters (an exception is a gas boiler with a coaxial chimney).

  3. Use of pipes not intended for heating systems. For example, they put polypropylene pipes PN10, which are intended either for a cold water supply system (SDR11) or hot (SDR6). And you need a PN16 or PN20 pipe.
    How to avoid mistakes – choose the right pipes, carefully read what they are for.
  4. Use of pipes made of different materials. First, it can lead to high internal stresses due to different coefficients of thermal expansion. Secondly, the occurrence of electrochemical reactions (corrosion) at the joints of pipes made of different materials. For example, copper and aluminum pipes cannot be connected.
    How to avoid mistakes – use pipes from the same material.

  5. Installation of radiators not intended for this system. There are two restrictions:
    • by the allowable pressure in the system (applies to the centralized heating system);
    • electrochemical compatibility of materials (which we talked about above).

    How to avoid mistakes – choose the right radiators in accordance with the operating conditions.

  6. Incorrect connection of radiators – mixing up the inlet and outlet when connecting shut-off and control valves. This leads to a loss of heat transfer from this heater.
    How to avoid mistakes – connect the radiator correctly according to the instructions.

  7. Lack of emergency draining (relevant for an autonomous heating system).

    • First, it makes repairs difficult.

    • Secondly, there are situations when it is necessary to urgently drain the water from the system or lower the pressure. How to avoid mistakes – provide for an emergency drain (and it is better to make it into the sewer system).

Benefits of self-creation of hot water heating

We wrote about the main benefits of a homemade heating system at the very beginning:

  • saving personal funds;
  • you do it for yourself, so you do it conscientiously.

But there is another advantage. You perform work at a convenient time for you. And if it is not possible to leave the apartment during the repair, then doing water heating with your own hands is an additional comfort, since there is no stranger factor.
