Structural features of the storage tank
Water heater - demanded appliance. For full operation he needs proper operation and scheduled maintenance.
Manufacturers and suppliers of the equipment are strongly advised to users without the urgent need to liberate the capacity of the water and to keep it empty for a long time. In this situation, the internal tank space is occupied by air, which adversely affects the surface of the tank and general condition of PETN.
Seating unit heating element with dry TAN placed in a flask and steatite is not directly in contact with the liquid. If it is damaged drained from the vessel is not required. Suffice it to carefully remove the spoiled part through the flange opening, and then return to its original location
More expensive units made of stainless steel and equipped with a dry TAN progressive ceramic coating, exhibit resistance to the influence of air, but the bulk of the cheap low-end models has no protection and remaining empty for a long time, and then goes down and needs replacement.
Therefore, experts recommend to keep them filled and the water is not lower without urgent need.
When you need to drain: popular reasons
The reason №1. In full discharge of liquid water heating tank needs if the room where the equipment is located, a long time is not heated.
For example, it may be hut not adapted for winter residence or any other seldom visited property owners, where the average temperature is below + 5 ° C.
In such a mode, the water tank and the pipes may freeze and there is a risk of damage of the inner container structure and binding. Therefore it is better to drain the liquid carefully in advance, and the very system mothball until a more suitable time.
If the boiler in the warm season will not be used for other purposes for a long time, you can not drained completely, but just once in 15 days to give her leak and upgrade. Then, the water does not stagnate, and comfortable to various microorganisms among the physical can not be formed within
If it is assumed that the device will not be used for a long time, the content of it can be updated 1 time in 2 weeks, opening for a few minutes on the hot tap mixer. So water will not stagnate, and it does not appear harmful microorganisms.
reason №2. Routine cleaning - another good reason for the complete emptying of the boiler. It is carried out once a year, where water is supplied centrally high-level purification, comprising at least part of impurities.
Twice a year the tank with constant use purified flow of water entering the system directly from the tank and passing through the sewage collectors.
When the heater is covered by a thick layer of scum, water heater during operation begins may consume significantly more power. According to specialists, the flow rate is increased by at least 25%, and in some very advanced cases up to 50%
In addition, inside the boiler during operation accumulate dirt and harmful bacteria, and the bottom walls and the heating element are covered with scale. Settling on PETN, it turns into a sort of insulator.
Then the following situation: the device itself in the process is heated very strongly and starts to overheat. Running water at the same time does not change the practical temperature and enters the system barely warm.
In the water heater is too clogged waste generated during the operation, performance deteriorates. The load on all of the key components is increased and equipment wear out much faster than the manufacturer
Efficiency of the unit decreases to a minimum under vigorous electrical consumption. To resolve this problem need to pull the tank, remove and clean heater from scale. Then, in the near future equipment can fully operate and change the water heater is completely not need a very long time.
The precipitate formed during operation in the storage capacitance adversely affects the quality of the water heating and worsens its full patency. To become a quality instrument to function again, will have to fully release the liquid, gently remove all the sediment and then continue operation as normal
reason 3№. emptying it may be necessary in the case when the unit is already out the warranty period, but some of the workers broke down the components.
For self-repair or replace heating PETN or magnesium anode have to completely drain the water, carry out all the necessary maintenance activities, then reconnect the equipment to the system and fill with fresh water.
Availability of leakage will also require compulsory discharge. Otherwise, find a weak spot and repair the problem will be very difficult not only to the house master, but also professionals in their field
For more information about the possible boiler breakdowns and how to resolve them written in this article.
reason №4. Another serious reason for lowering the water - an unpleasant odor released from the tank. He usually appears in very rare use of the equipment. Water in the tank without regular updates, stagnant, silt and starts to smell.
After complete emptying and filling of the reservoir with fresh fluid, "aroma" disappears and is no longer concerned about the residents of unpleasant fumes.
To limescale not remain inside the tank, preventing the flawless operation of the safety valve, separate manufacturers of home appliances recommend customers monthly pour a small amount of water through a separate drain pipe
reason №5. In addition to all the above reasons, the devastation can be necessary in case of dismantling the tank and transfer it to another location, for example, during a re-planning of premises, and the current capital or cosmetic repair.
In some cases, it is not necessary to drain the water
Lower the water heater and leave it blank need not in all cases. Planning to "preserve" the equipment for a long time, for example, for the summer, it is better to leave the inside of the vessel a little water.
It will not be formed early corrosion and will protect the unit from the fire, if the owners come back suddenly and accidentally, inadvertently, will include an empty heater.
When there is a desire to get rid of stagnant water, which has become stale during downtime, complete draining operation it makes no sense to spend. It is better to retype several times the capacity and update the contents of the tank.
Incidentally, such a procedure experts strongly recommended every 2-3 months by passing through the apparatus for washing at least 100 liters of cold running water.
In located on the boiler warranty handyman penetrate highly undesirable. If, after the loss of tightness of the system need to contact the service center, warranty repair nobody will take place.
interventions should be so obvious that the staff noticed this and immediately cancel a grace period of service and provide free services will no longer be.
If we turn to the experts or representatives of the service center, professional masters will leave in place, will appreciate the level of damage and quickly resolve it. Think about the flow of water and other components such work does not require owners
It is not necessary to lower the water just to see the internal structure of the tank, or to learn in such a way that in the future to do everything yourself, and not to resort to highly paid masters. It is better to carry out works only when an acute need. Then the equipment will be fully working and not give the owners any trouble.
How to start the process
No matter which company water heating device is used for the correct discharge of the process is necessary before starting work disconnect the unit from the mains. This will protect the equipment from short circuit, and the master will avoid potentially possible injury.
Drain the hot water tank is strictly forbidden. Ignoring this point is fraught with burns to an employee performing maintenance
Then you must use the valve to block flow in the tap water tank and leave the boiler switched off for some time, until it is completely cooled. When these parameters are met, will have to carefully remove the tube, feeding a hot and cold water, and only after that start already directly to a drain.
Description popular ways
Draining a water heater can be a variety of ways. All of them are not too complex and operate on the same principle. Minor differences are due only to structural features used boilers.
The work does not take much time, but requires DIY accuracy, thoroughness and pedantry. If we approach the issue carefully and responsibly, the process goes smoothly and will not have a negative impact on the construction and subsequent operation of equipment.
Draining through the safety valve
Communication system, which includes initially correctly installed boiler, assumes that the drain of the safety valve. Usually it is located on the cold pipe or bar just before entering the tank. This element is intended for emergency drain water from the boiler tank.
draining process is performed spontaneously, when, due to some reason the pressure inside the tank exceeds a safe level. Himself safety valve is equipped with a screw handle and a special spout, which is very convenient to connect the drain tube.
Checking unit makes monthly performance. To do this, open the valve handle and wait a while. Smooth flowing stream of water indicates that klapanovoe device is in working condition and fully perform its functions.
If the water flows very weak or does not pass at all, it means the channel is clogged valve and its direct safety function is not executed. After receiving this information, it is better to respond to and clean the element to further complete the work.
When the item is not subject to the purification, it is recommended as soon as possible replace the safety valve on new.
Through the safety valve the water flows very slowly. For 2 chasa manages drain no more than 80 liters of water. At this time, clogging the valve will increase by 1-1.5 hours, depending on how badly clogged klapanovy channel
Drain water through the safety valve is the most simple, affordable and the inexpensive. To implement the process, you need only turn the valve responsible for the emergency device. When water valve operable immediately pour from the spout or tap hose attached thereto.
The owners will only have to wait until all the water has drained, and then make all the necessary with boiler manipulation: to preserve for the winter, to change defective parts, to eliminate the unpleasant smell, make scheduled cleaning and so on.
Emptying of the tank through opening for cold water
Draining the water heater through the outlet opening for cold water is more complicated than the above described, and requires the attention of DIY, a responsible approach and the availability of some workers skills.
To carry out the task will have to arm themselves with a wrench and remove a certain amount of nuts to ensure the integrity of the structure.
Unscrewing the nut of the water heater, you need to act very carefully and cautiously. If the thread is in the process of dismantling it will be torn correctly assemble the boiler will not work
Step by step instructions, created by professionals for domestic masters, recommends action in the following order:
- Disable boiler capacity from the power supply and shut off the premises of cold and hot water.
- Check whether the hot valve is closed, or after the loosening of nuts water flows too much and will flood necessarily kitchen.
- Under the storage tank to put the right size container for draining the working water.
- Remove the nut connecting the relief (bleed, reverse or emergency) valve and Plastic communication pipe (or hose).
- Using wrench gently unscrew the nut, a safety fastening (resetting) the valve and the nozzle of the heating unit.
- Remove the 'dump valve and assess his condition. Upon detection of clogging rinse thoroughly under running water detail.
- Open valve for hot water and provide air flow inside the sealed tank. After these manipulations of the cold water flow pipe significantly faster.
- Adjust the level and strength of the flow will help the hot tap. If the reset is too much, the valve can be a bit screwed.
- If the communication system is mounted on the hot nozzle discharge valve, you can control the level of the drain with it, without using the standard hot tap.
Provided that everything is done correctly, the water from the heating tank runs out completely for 3-5 minutes, depending on the volume of the unit.
the flow of water through the holes for hoses
Very quickly empty the water heater can drain the working fluid through the hoses, responsible for supply / discharge of hot and cold water. However, this method is suitable only for those units, which are located just above the bath. Functions of control over the power and speed of any drain in this embodiment, no.
Return to the boiler operation after discharge, sediment removal and cleaning of heating element must be very careful. Capacity have to be filled with fresh water. Connecting to the mains empty unit may trigger a short circuit and even cause a fire
To enable the process, it is necessary to unscrew and remove the inlet pipe for cold water and a safety valve. Then, remove the hose from the pipe for hot water.
All fluid available at the time in the tank, literally for 1-2 minutes in a bath drained and the unit becomes accessible for routine cleaning, maintenance and completely disable the purpose of conservation for the winter.
How to remove the remaining water
Regardless of the manner in which water is drained from the water heater to remove it completely and without reserve will not work. This is due to structural features of a boiler tank.
To remove every drop, have almost completely disassemble the machine, clean the inner surface, troubleshoot, and then either preserve the system until the next use or assemble the unit again, put it back in place and continue to operate in the ordinary mode.
Rules completely empty boiler
It is necessary to drain the bulk water with one of the most convenient for itself above described methods. Gently unscrewing the decorative cap disposed at the bottom of the tank.
Hold it with your fingers, carefully pull off the wires, fastening alarm lamp to the surface. Then also remove electrical wires, pre-memorizing their exact location.
In case you want to completely disassemble the boiler, it is necessary to pay special attention to the placement of connectors and electrical wires. So you do not confuse, it is desirable to take a picture of their current position, and only then proceed to dismantle
Then slowly and counterclockwise to unscrew employee support for the heating element flange. Gently loosen the nuts and allow the construction of the remaining water to drain from the boiler capacity. In the end, completely unscrew the nut and remove the flange. Very slow to get out of the recess TEN, taking care not to damage any of the tank surface, nor the very detail.
If the heater can not be ejected immediately, then it was covered with a thick layer of scum. Not to deform it in the process of taking out, you need to gently shake the item right to left, gently pulling up parallel
Pour the remaining water from the boiler drops, clean surface, and then reassemble the unit mounted in the communication system and begin to use the standard mode.
Necessary tools to work
The process of emptying water heating units of different manufacturers on the basic principles are very similar. The basic tools necessary for correct operation are traditional adjustable wrench and rubber bight designed to drain fluid.
Drain the water from a boiler can be compact, not only in the bath, but also in ordinary plastic bucket. If you plan to empty the tank is large, it is better to prepare a basin or any other container with a good capacity, otherwise the water just does not fit, and at the end of the work will have to spend extra time cleaning room
To service some models of boilers, for example, firms "Ariston", "Electrolux", "Thermex" and so forth. handy screwdrivers with different-sized nozzles Spanner and hexagon.
Hose to drain the fluid fitting lowered into the bath. If this possibility is not an objective, it is necessary to find a practical and comfortable large container, which in the process of emptying the boiler drain waste water.
