How to replace the battery yourself

In the context of a total struggle for savings, increasing the efficiency of the heating system is one of the priority tasks. To solve it, it is necessary, first of all, to replace the old batteries with new modern heating devices. How to do it yourself is described in this article..

In order for the house to always be warm, it is necessary that all heating devices work with maximum efficiency. In many houses, to this day there are obsolete registers with low efficiency. In fact, heating residential premises with such batteries is a waste of money. Replacing old batteries with new ones will significantly improve indoor comfort while reducing heating bills..

First, you should talk about the types of modern batteries. They can be conditionally divided into three classes:

1. Steel, battery with steel casing. To increase the heat transfer area, and, consequently, the efficiency of such batteries, it is necessary to make a very large number of internal partitions. As a result – a rather high cost – a two-kilowatt battery will cost about 3,500 rubles.
2. Aluminum. They have thicker walls than steel walls and, accordingly, a higher efficiency. They are susceptible to the destructive effects of alkali, which is added to the water flowing in heating systems, so that scale does not form on the inner walls of heat pipes. Cheap material and ease of manufacture provide a low price – about 2,000 rubles. per battery with a capacity of approximately 2 kW.
3. Bimetallic. The inner part is steel, the outer part is aluminum. They combine the advantages of the previous types of batteries and do not have their disadvantages. The average price is about 2600 rubles. for two kilowatt.

Thus, when installing a battery on a central water supply system, it is necessary to use either steel or bimetallic radiators – aluminum will quickly collapse under the action of alkali. When installing an autonomous heating system, for example, in private houses, in order to save money, it is advisable to use aluminum radiators.

So let’s get started. Replace old registers with a modern battery.

Required tools and materials

To carry out the work, the following tools are required:

1. Angle grinder (grinder with a disc for metal).

2. A set of keys.

3. Rotary hammer with a drill with a diameter of 12 mm.

4. Soldering iron for polypropylene pipes with a diameter of 25 mm and cutting shears.

5. Building level, tape measure, pencil.

Materials:

1. Polypropylene pipe with a diameter of 25 mm, fiberglass reinforced.

2. Fittings and accessories for polypropylene pipes.

3. Battery connection kit.

You can buy all these elements separately, then you will need:

• radiator plug 1 “x?”: left – 2 pcs., right – 2 pcs.;

• plug? “, drain valve – Mayevsky valve;

• corner faucet? to the supply and return line;

• fixing the battery to the wall.

4. The battery itself.

Battery Replacement

1. The most difficult stage of any work is dismantling the old system. We drain the water. We make two deep cuts on the pipe at a distance of about 15–20 cm and, using a gas wrench, carefully break off a piece of pipe. It is not worth cutting off the pipe completely, as internal stress in the pipe can jam the disc, which can lead to tool breakage and injury.

2. We remove old pipes as much as possible. In our case, to the plug of the neighboring radiator along the water supply branch, and the outlet angle along the return.

3. We wind the reel onto the transition fittings and screw them into the supply and return.

4. We mark the place of attachment of the battery using a level and tape measure.

5. We drill holes in the right places, insert dowels and screw in radiator hooks.

6. We begin to tie the battery. First we screw in the plugs – two with the right thread, two with the left. Since there is an O-ring on the plugs, you do not need to use a rewinder.

7. In the upper part of the battery, we screw the tap with the American into the supply. To do this, we use the handle of the gas wrench and the projections on the inside of the American woman. Do not forget about reeling.

This valve controls the temperature of the battery. We open the tap. To do this, twist it to the side with a sign +.

8. In the lower part of the battery, opposite to the return, we screw the cap.

8.On the other hand, we turn the tap onto the return line and open it with a hexagon.

9. In the remaining unused upper battery plug, screw the drain valve. Since it has an O-ring, no additional rewinding is needed.

10. We hang the battery in place. We install the supply and return lines made of polypropylene pipes. Observing the order of pipe soldering, we solder the battery to the line.

When installing polypropylene pipes, it is necessary to provide for expansion gaps when the pipe is heated. Pipes should not be cemented when passing through ceilings and walls.

11. It remains to fill the system with coolant and bleed air using the Mayevsky crane.
