Repair of the heating radiator

technology and sequence of repair radiators depends on the type and design of the battery itself.In addition, important and failure cause.For example, a bimetallic radiator repair is not much different from any other repairs, it all depends on the specific situation.Next, let us consider in detail how to find, locate and troubleshoot heating radiators.

types and design radiators

in this article, we will examine the sequence of repairing such types of radiators like:

• steel radiators,
• aluminum radiators,
• cast iron radiators,
• bimetallic radiators.

for repairs should also take into account the design of the radiator.Basic kinds of designs Four:

• Sectional radiators - assembled from separate sections of the same type, securely fastened together.
• Monolithic radiators - are one big-section of the body.
• Tubular radiators - has no unifying body, becausecoolant is circulated through the pipes that make up the radiator housing.Often performed in non-standard shapes and sizes.
• panel radiators.It consists of two metal plates which are welded together.

To begin to repair the radiator, you need to know what are the main and additional elements, parts and components are included in its design.

general device

radiator batteries Consider the components and parts, which are equipped with radiators.Depending on their type and design, accessories and additional devices will be different, but in general, the list of possible components, the following:

• section and tubing - Channels, inside which circulates heat-carrying fluid,
• tubes - are connected with pipes to supply anddrain coolant,
• split ring - closed pipe exit out of the wall panel,
• plastic rod - captures the split ring,
• plugs - caps on the sides of the radiator,
• ball valve with a valve - to shut off the circulation of the coolant,
• bleed screw- for manual pressure relief in the heating system, as an option, set the automatic pressure relief valve,
• thermostatic head, by means of which adjust the room temperature,
• steel sleeve, Intersection nipples, silicone gaskets - are placed in the ground sections of the connection,
• couplings, locknuts and brackets for attaching radiators.

The aluminum radiator package sometimes includes circulation pump, which provides uniform heating of premises.It is also used for other radiators bottom connection is established when the heating system, ie,tubes suitable for the radiator below.In this case, the use of a circulation pump must otherwise significantly increase the level of heat loss.

Symptoms and causes damage to radiators

Possible causes of damage and damage to radiators:

1. originally incorrectly chosen radiator.Depending on the diameter of the pipe, the pressure and temperature of the water in the heating system, install various types of radiators.
2. Improper connection to the radiator heating system pipes.
3. harsh environments centralized heating system.Increased acidity of the coolant and the sudden pressure changes lead to electrostatic and electrochemical metal corrosion.
4. heating medium to poor quality of the heating circulation system forms a plaque at the junction of sections and at fixing pipes.
5. Poor quality coolant clogs radiator sections and the radiator as a whole.This makes it necessary to periodically wash them.
6. degradation intersectional seals and the destruction of the threaded nipple.It is necessary at regular intervals to replace the gasket between the radiator sections.

main signs of breakage and damage of radiators, the following:

• during the heating season in the premises was colder than usual,
• at the junction of sections and attachment points formed plaque,
• there was a leak.

If the radiator is very old, it is best to replace him.Modern models are more efficient, have a high thermal conductivity - in the house will become warmer and heating costs decrease.In addition, the new batteries are compact and feature beautiful design.

In the case where there is no possibility to change the radiator, it is necessary as soon as possible to correct the damage.The best solution - to turn to specialized services or resort to the help of professional artists.But it is also possible to try to repair heating radiators with their own hands.

Repair sectional radiators heating own hands

for sectional radiators the vast majority.First of all - this iron and bi-metal, less metal.

course, preventive maintenance radiators is best done before the start of the heating season or after its completion.Often, however, we start to do something only when a problem becomes critical.The main reason why it becomes necessary to repair - a hot water leakage.Therefore, below is a guide, how quickly to repair a radiator own hands and get rid of the leak:

1. diagnose leak.Often the place where water flowed, it is visible to the naked eye.But there is also such that it is difficult to identify.In this case, the radiator must be dismantled and immersed in a water bath.From the spot where the hole is formed, the bubbles begin to rise with the air.However, most often necessary to remove the battery is not present, and the repair is carried out locally.

2. Prepare tool.When it is determined a place of course, you must go to repair the radiator.To do this, prepare the following tools and materials:

• thin steel cable,
• putty.You can use to choose from: a mixture of epoxy resin and a metal (aluminum or bronze) powder;dough-like zinc oxide;powdered polymer or sealant;"Cold welding" (note that it is water-resistant and withstands temperatures up to 100 ° C),
• cloth, bandages or other tissue for applying putty,
• metal clamp.If it is not - duct tape (or rubber) and wire.

3. We equip the place of repair.Under the battery put the oilcloth, waterproof fabric or a piece of film.Top - a large cloth, which absorbs water well.If necessary, place near a basin or bucket to collect water.

4. Produce cleanup spill area.The most common location of the leak - the joint between the radiator sections.In this case, you must remove the old winding, remove the pieces of shattered pads and layers of paint.Use the string (a thin rope with knots on the ends) and smooth out the damaged joint to the metal.Rinse the cleaned area with acetone or gasoline to the new winding is firmly entrenched on the radiator.

5. gloss over the damaged portion of the radiator.Mix the epoxy resin and metal powder composition to apply a narrow strip of tissue.Maximum tightly wrap the tape with the mixture at the junction of two or three layers.If the funds are applied obscure zinc white, whereas - in four or five layers.At the use of "cold welding", you need to cut a small piece of it and stretch his hands until smooth.Welding seam is applied on the circumference, does not need to use fabric ribbon.

6. Fix the smeared portion of the metal clamp.Place the clamp over the putty.Pull it, and firmly secure with bolts and nuts.Connection clamp should be in the side opposite to the flow.If there is no collar - use adhesive tape or a piece of rubber.Rubber better cut of elastic medical harness or bicycle inner tube.Tape or rubber wrap in several layers, the edges tightly twist the metal wire.

When the heating season is over, it is recommended to replace a faulty radiator or at least its damaged section.If this is not possible, you should remove the old winding and process flow of the place again in the same way.It must be done before the next heating season, to the new winding had time to dry thoroughly.Repair of cast iron radiators is carried out in the same way.

Repair aluminum radiator by brazing

In some cases, damaged areas of the aluminum heat sink is necessary to solder.If you have skills with a soldering iron, to carry out such repair is not difficult.However, note that aluminum and its alloys are difficult to solder, therefore, to carry out this work to be very careful.So:

• prepare the surface for soldering and put on her train rosin flux;
• heated soldering iron, wipe the affected area;
• when rosin will be spread over the surface, enter the tin-lead solder with an admixture of iron filings.

The sealed aluminum radiator is recommended to re-paint.To do this:

1. Erase the old coat of paint special stripper.
2. carefully crafted radiator sandpaper.
3. heat-resistant paint or enamel, apply an even layer from the top down.If the radiator is a sectional, start painting with areas between sections.Note that when painting the radiator should be cold.

Some tips and tricks to increase the heat in the house

Finally, some suggestions for improving the work of radiators and heating system as a whole:

• radiator painting (particularly iron) in the dark increases the share of heat withdrawnradiation.
• recommended distance from the radiator to the window sill - 100mm, and wall-to-battery - 20 mm.Otherwise, the heat flow is disturbed and the efficiency of the heating system is reduced;
• To increase the heat radiation directed into the room, attach to the wall behind the radiator heat insulating film with foil surface.

• optimal distance from the surface of the floor to the battery - 120-150 mm.If you do not follow this rule, sudden changes in temperature will cause drafts in the house;
• When connected again (when hot water is supplied to the bottom of the radiator) the total power of the system is reduced by about seven percent.
• The effectiveness of the heating system is also greatly influenced by the place of the radiator installation.The maximum effect is achieved by placing under the window sill - 96-97%.If the battery is located in a recess in the open state, the efficiency drops to 93%;If the radiator is covered in part - to 88-93% if the full - up to 75-80%.
