Which water heater better flow or storage?

It is necessary to ensure an uninterrupted supply of hot water in the apartment or in the country? Let's look at the pros and cons of electric flow and storage water heaters, and find out what is best to choose a boiler to the house was always hot water.

The competition between the storage and flow heater - a competition between the cumbersome and compact, economical and wasteful

Overview of storage-type water heater

Water heater appearance often resembles a hanging on the wall of a barrel

In order to understand the positive and negative features of the storage water heater is covered at its structure:

Structure

Schematic representation of the structural elements of the electric storage-type water heater

From the scheme above highlight 4 basic elements:

1. Tank. Availability imposing the tank allowing water to accumulate in store, you will notice immediately, since its amount can range from 10 to 500 liters. This allows the boiler contain required for all tenants of an apartment or private house the amount of water the right temperature.

From the storage volume of the boiler directly depends on its performance

Tanks in water heaters are usually made of high quality stainless steel, less copper and very rarely made of special plastic. Inside they have a corrosion-resistant coating.

Internally coating protects the tank from corrosion

In this case, the best water heater - this is the most difficult water heater. High weight means having thick walls in the tank, whereby the limited thermal deformation of the material of which it is made. As a result, the anticorrosive layer is kept much longer, thereby prolonging the service life and the entire device.

Even in cramped conditions, choose a boiler with thick walls - so the machine will last longer

The approximate amount of the necessary equipment you find it easy to:

• Number of people. All who live regularly in the house or apartment;
• Consumption. Standard - 20L, as that is how much the average person spends on himself when visiting the bathroom;
• Payment. Multiply the number of guests on the consumption and add 12 liters per washing dishes. More add 10-20 liters per force majeure situation.

1. TEN.

The boiler two types of heating elements can be mounted:

• Tubular. This hollow tube of metal, inside which is a conductor having high resistance. That he is heated by passing electrical current through itself. In order to implement such a device inside the insulation dielectric filled with sand.

The curved metal tube, the sand and the conductor - the device tubular heating element

The main problem of such heating elements is the formation of a large amount of scale on the outer wall surface;

Here is the dry heater, covered with scum after a long working period

• Dry. Here we can observe a similar structure of the embodiments described above, which is supplemented by a protective bulb with a special oil or quartz sand. As a result, the price of such products increases, but with scale problem disappears;

Dry heater increases the cost of the entire boiler, but it does not collect on the walls of their scale

As for the power parameters, the most optimal one are heating elements 2 kW. This will be enough to maintain the required temperature of the water in the tank, and at the same time does not require an extra power socket;

It is advisable to have your water heater PETN selected area as large as possible. Heat dissipation in these devices more and scale adheres less.

The more surface area contact with water, water heating element, the smaller scale accumulates thereon

1. Thermostat. It can be used to expose a certain heating water temperature in the boiler. Once this is achieved, the heating element is switched off. And when the liquid cools down at least half a degree, he began working again.
   This is another fundamental feature storage water heaters, allowing the use of electricity is not constant, but periodically.

The thermostat allows TENu not constant, but periodically, while saving power consumption

As of today, you can often find upgraded performance monitoring and control system of the boiler. They thermostat supplemented personal microprocessor expanding functional device and an external display, which displays the exact temperature and the self-test results. But I do not advise in this case, to strive for technological advances and hurry to part with their hard earned.

On modernized management screen you can see the water temperature with an accuracy of one degree

The problem is that the microprocessor card is very easily damaged during temperature changes or stress. And they are not only very difficult to change their own hands, but even to be found in the service centers is not always possible to;

If you still decide to purchase a water heater with a microprocessor, I recommend immediately buy and voltage stabilizer. At least, from the fluctuations in the power network so you can protect expensive equipment.

voltage regulator extends the service life of the heater electronics, protecting it from power surges in

1. housing. It combines all the functionality of the boiler and is supplied with the mounting system that allows the device to perform the installation on the wall. Which to choose a water heater in accordance with the structural element?

Let's see:

• Firstly, one that seemingly fits the design of the room in which you plan to install the equipment. For interior beauty care should be taken in any case;
• Secondly, the one with the acceptable thickness of the insulation. The space between the tank and the outer walls of the housing is filled with polyurethane having excellent thermal insulation properties.

Why is this done? To provide slow cooling water in the boiler and thereby reduce the number of inclusions and the operation of PETN.

One millimeter of this material allows to keep the difference between the temperatures in the boiler room and 1.2 0C. The thermostat is often put on a mark of 65 0C. The air in the kitchen or bathroom average warmed to 23 0C.

We make simple calculations: (65-23) / 1.2 = 35 mm. This is the minimum thickness of the heat insulator, which will allow the heating element to stay most of the time off, saving your finances.

In the schematic illustration in section of the boiler body can be seen the main structure of its layers

dignity

Based on the described apparatus, can easily identify the main advantages of which have a storage-type water heaters:

• Economical power consumption. Heater does not run continuously when tap is open, but only periodically switched on for heating the water;
• Coverage of all intake points. The apartment or private home to the boiler storage type, you can connect mixers, tank toilets, dishwasher and washing machine. The question is only in its volume;
• simple instructionsinstall. In fact, the process is no different from the mounting flange, only fasteners may require stronger in line with the size of the water heater. Connect also does not require the presence of any specific skills.

disadvantages

Negative aspects are also available:

• Big sizes. Stolitrovy device, designed for a family of medium size, take a lot of storage space, which sometimes for our small apartments catastrophically;

With such a neighbor in a small bathroom becomes closer

• The low heating rate. With the right choice for your family tank volume you this nuance does not cause problems. But if suddenly the whole warm water will be used, then someone will have to wait very long for its replenishment.

Review of flow-type water heater

Instantaneous water heater has a smaller and more power, which makes their pros and cons

The flow-through water heater uses a fundamentally different approach to the production of hot water, which is visible from its device:

device features

Inside view of the flow-through heater impresses with its simplicity

1. Lack of accumulation tank - the most conspicuous part. Due to the dimensions of the device once it is reduced by several times, but no constant supply of hot water;

Compact boiler flow type of work in the presence of a suitable existing socket can be used even in the street

1. high power. Used flow-through units of heating elements depending on the models consume from 3 to 30 kW. After all, you need to have time to heat the liquid at the time, until it flows through the heating element, which requires huge by the standards of consumer sphere of energy.

TANS instantaneous water heaters have a high power to enable them to heat water in seconds

dignity

As a result, you can highlight the following positive aspects of this type of heating equipment:

• small size. Instantaneous boiler takes up little space and will not disturb you. Even more, there are models that simply and completely integrated into the mixer;

You do not even feel the presence of the additional flow model heater household appliance in the bathroom

• High fluid heating rate. No danger suddenly find themselves without hot water while taking a shower or other water treatments;

While "protochnik" works properly, the hot water will not go away

• Additional equipment. Together with the boiler itself, in most cases you will get in addition faucet and shower heads with a hose that all together is a complete shower system.

Flow boiler, complete with mixer and a watering can with a hose, will provide you with a full shower

disadvantages

Excessive power consumption has two negative traits:

• high scoresfor utilities. High power - high energy consumption;
• The need for special conditions. Installing the flow-through water heater can be even impossible in everyday life. After all, not every Posting withstand the load even relatively feeble samples in the 3-8 kW, not to mention the monsters, the heating elements which consume 20-30 kW;

Before you install any "protochnik" home, you should consult with a licensed electrician who is familiar with the electrical wiring in your building. And only if he would allow, implement the plan. Otherwise, you can stay even without electricity and provoke fire.

The result of overloading the mains can be a fire in your apartment
