What is modulation flame in a gas water heater

Gas water heaters

Gas water heaters. traditional equipment with modern features Many Ukrainian consumers are not by hearsay familiar with this type of water heater, as a gas water heater. Back in Soviet times, in the apartments of our countrymen began to appear such devices, which to this day have not lost their popularity. However, modern gas water heaters have a number of significant differences from their predecessors. They are not only visually more attractive, but also have improved functionality, easier and more convenient to use, as well as more durable. In this case, the principle of gas water heaters has largely remained the same. This is a powerful and economical equipment, which instantly heats up and efficiently copes with its duties.

Water Heater Troubleshooting | Clean the Flame Sensor

Large selection of gas boilers at pleasant Household boilers are designed to heat water by using natural gas as fuel. Installation of such equipment will give the opportunity not to depend on the central hot water supply and enjoy the benefits of civilization around the clock. Gone are the days when the water is fed only on a schedule. Today, gas water heaters provide people with comfort and convenience every day. You can buy the equipment:

Hydrodynamic, which operates like a water power plant. When you turn on the water, the small hydro turbine of the gas water heater begins to produce electricity, and the flame of the burner is ignited by a spark; semi-automatic, which is triggered when the user presses a special button. The disadvantages of piezorazhizni can include the fact that the equipment consumes a lot of gas during the entire operation. Even if you do not use water, the resources are still consumed; Automatic, which turns on at each consumption of hot water. It is sufficient to open the faucet, which activates the electrical ignition. As soon as the water supply is stopped, the igniter goes out, which prevents unnecessary consumption of gas.

Online store TEPLODOM offers to order gas water heaters of domestic and foreign manufacturers with delivery in Ukraine at an affordable price. The site presents models of different capacities, with a function of modulation of the flame, as well as the type of ignition. You can choose and buy exactly the speaker that will suit your own characteristics. Water heating equipment for sale is available in wholesale and retail.

How to choose a gas water heater? Deciding to buy a gas water heater, it is worth to understand the main criteria that determine its characteristics and affect the price. First of all, the cost of gas water heaters is determined by the reputation of the manufacturer. Next comes the power, ignition type, burner type, security measures, additional options, etc. We offer you basic recommendations that will help you to understand which gas water heater you need!

Power. Determines how much water the unit can heat in a unit of time. Conventional, there are three types of gas water heaters, which the online store offers to buy:

High-power devices: 28-31 kW; medium-power devices: 22-24 kW; low-power devices: 17-19 kW.

This figure is chosen solely by taking into account the individual needs of the user. When calculating the capacity, it is important to consider how many points of water intake the gas-flow heater will have. If the water will be consumed in several points, it is desirable to choose a more powerful model with good performance.

Burner type. The price of gas-flowing water heaters also depends on the type of burner: there are constant-power and simulation burner. The first type requires manual adjustment, which is not always convenient, because the water pressure varies. The simulation power keeps the temperature constant and automatically adjusts to the water pressure. Therefore, we recommend buying a gas water heater with a modeling type of burner. it is much more practical. Type of ignition.

Budget gas water heater for heating water has a manual type of ignition. To ignite the heater, you need to press the button and bring a match to the burner. This is inconvenient, unsafe and not very economical. But for such a gas water heater, the price is the lowest. Piezo ignition activates the water heater by pressing a button. This is a variant of the electromechanical match included in the design of the system. The main advantage is that you can buy a gas water heater inexpensively. But in terms of convenience it is not very different from the first type. Electric ignition system. This is a modern gas water heater for heating, which allows you to turn on the water heater automatically, which is very practical and convenient can have an energy-independent and energy-independent ignition system. everyone has the right to choose the more convenient option for themselves.

Turbine gas-flowing water heaters require installation of a pipe under the speaker directly in the wall. This is risky enough, especially in winter, when the water tends to expand. It will have to be constantly drained so as not to damage the heat exchanger. Chimney gas heaters to buy Ukraine offers a wide range, as they are more reliable and safe. The design involves the conclusion of the heater corrugated tube directly into the chimney.

Safety. Deciding to buy a flow-through gas water heater, you can not neglect its safety, because in the water and gas supply often malfunctions. In order to safely use the unit, it is worth choosing a model that has such sensors:

temperature: regulates the power of the flame; ionization: water heater instantly stops when the wick fades (gas is not fed); overheating: does not allow the water to overheat, so the heat exchanger does not deteriorate and limescale is not formed; draft: if there is no draft in the chimney, the column does not turn on (with this sensor to buy a gas water heater Kiev recommends those who are afraid of carbon monoxide formation in the room); flow: turns on the heater when you open the tap and turns off when it is closed; safety: when the water pressure in the system increases the heater is blocked.

What does the price of the gas water heater depend on? The cost of gas boilers directly depends on their characteristics and the reputation of the manufacturer. Thus, the highest for gas water heaters Kiev sets on models of German brands Bosch and VAILLANT. They are equipped with a modulating type of flame, have a closed combustion chamber and a full set of safety features. Inexpensive gas water heater in Ukraine you can buy from manufacturers Rocterm, Termaxi, RÖDA, Zefiro, Ariston, Beretta. Typically, these models have a piezo ignition and an open combustion chamber.

In any case, having decided to buy a gas water heater in our online store, be sure that our consultants will help you to decide on the choice and prompt the optimal model for your budget and requirements. We offer a wide range of gas water heaters in Kiev and all of Ukraine!

Boiler automatic. what is it

Despite the stylish name, this term means a gas boiler of flow type, in which the ignition of the burner is carried out by an electronic unit, without human intervention. Otherwise automatic gas columns work the same way as semi-automatic.

All built-in functions: flame modulation, automatic temperature control and others are present, regardless of the type of ignition used. For this reason, to claim that the semi-automatic is definitely worse, would be hasty and erroneous opinion.

The principle of automatic boilers

The technical and operational characteristics of water heaters derive from their internal structure. In other words, the principle of operation of the automatic gas water heater directly affects the usability, efficiency and other operating parameters. Switching on and off a battery-operated or mains-powered water heater is as follows:

  • There is only one gas burner in the device;
  • When you open the tap of the DHW water flows into the reducer, connected to the gas valve and the ignition unit;
  • The pressure created sets in motion a rod that gives a signal to supply gas and generate a spark that ignites the gas;
  • after closing the tap of the DHW, the boilers with the automatic on/off switch completely fades.

modulation, flame, water, heater

In the latest generation water heaters, the ignition is carried out with the help of a hydro-turbine. Auto ignition uses electricity generated from the movement of water. Otherwise, the operation of the heater is identical to the one that runs on batteries.

On the outside of the casing is a mechanical or touch screen control box: two levers that change the pressure of the gas and water to the burner and the heat exchanger. The settings are permanent and do not change in the process of water heating. When you change the head changes the intensity of DHW heating.

Gas water heater with automatic water temperature control has a modulating burner. The user sets the desired intensity of DHW heating, which fundamentally changes the purpose of the automatic control. Sensors control any changes and at a lower or higher water pressure, automatically adjust the work of the burner so that the DHW output was the desired temperature. Typically, these speakers have an electronic control board.

Pluses and minuses of electronic columns

Automatic flow-through gas water heaters have several positive aspects that explain their popularity and demand among domestic consumers:

  • Economy. in the process of heating water columns burn the same amount of gas as the semi-automatic models. Costs are lower due to the absence of a permanently lit ignition wick.
  • Ease of operation. automatic gas-fired instantaneous boilers turn on automatically when you open the tap DHW and turn off immediately after closing it. On the external front panel there is an LED display connected to temperature sensors and indicates the temperature. To adjust an automatic gas water heater is not difficult, enough by turning the knob to change the water pressure or gas pressure, focusing on the digital value of heating. Models with electronic control are equipped with a touch panel, which adds even more comfort.

In boilers with the function of flame modulation there is an automatic temperature control, but this plus also applies to similar models with semi-automatic ignition. If we talk about the disadvantages, the price of the equipment comes to the fore. The cost of automatic gas water heaters will be higher by 30-50%. The reason for the high price is related to the ignition unit and the electronic temperature regulator.

There is a second disadvantage associated with the listed units. As statistics shows, the most frequent breakdowns of the water heater occur due to malfunctions in the ignition unit and regulator. The causes of failure are from the most banal: dead batteries (will need to change every few months) to complex: failed spark production unit.

Popular models of automatic boilers

Safety of using the column

Before making a purchase it is worth checking whether the heater is equipped with the safety features required for gas appliances:

  • Flame detection sensor. It is located right next to the main burner and if there is a flame, it ionizes the space between the electrodes, thus giving a signal to the gas fitting to keep the gas valve open. If the flame does not ignite. the gas valve is closed.
  • Chimney draught sensor. In the event that the chimney draft is insufficient, the flue gases are extracted through special channels, acting on the sensor. In the case of such a leakage the heater is turned off.
  • Temperature control. This sensor monitors the temperature in the heat exchanger so that it does not exceed a value close to 100 ˚ C. In the case of extreme heat, the gas supply is also stopped.

Gas water heaters today are not commonplace devices, which are hard to ignite with matches and highly dependent on the pressure in the water supply. On the replacement of outdated equipment come modern devices. Among them the special place is occupied by the gas burner with a modulating burner. The possibility of changing the flame power is one of the main options of the device.

Often are faced with drops in water pressure? Tired of being dependent on users through other points of intake? The ideal solution is a gas-fired, flame-modulated heater. Now during the shower there is no fear if someone uses the bathroom, opens the faucet in the kitchen with hot water there will be no surprises with boiling and freezing shower. It is possible that in winter, the water will come first from the riser pipe and then sharply from the pipe outside. Here it is not possible to change the water temperature by turning on / off the faucet, the option of reducing the combustion power or (in the case of too hot water) the additional use of a cold faucet. But that’s dangerous for the heat exchanger.

Flame modulation is the automatic variation of the intensity of combustion depending on the heat demand. The required amount of heat is determined by the automation unit and depends on the water heating temperature set by the user.

Gas-fired column with flame modulation provides users with a high level of comfort. you only need to set the desired temperature of water heating, and the speaker itself will maintain this temperature indicator. Modulation avoids the unpleasant situation of turning on the second tap and running cold water from the first tap.

The main advantage of a burner with a modulating burner is its cost-effectiveness. The fact that when the water reaches a predetermined temperature, the burner reduces the intensity of combustion to a minimum. If the water begins to cool, the flame increases until it reaches the desired heat. So the burner uses the optimum amount of fuel and does not allow its overspending, which saves significantly on gas costs.

Multistage burner is capable of changing the output from 40 to 100%. over, the modulation of the flame extends the life of the heat exchanger and the device itself.

Smooth modulation of the flame. what it is?

Criteria for selecting heating units or flow type water heaters, in which the heat source is a burner, quite a lot. All of which are usually known to most potential buyers. But the question of what flame modulation is, only a few will answer correctly; tested, and more than once. But this is not a minor factor, and it is worth considering when assessing the reasonability of purchasing equipment. That is, to ask if the device you like has such a function or not. So why do we need it and whether this engineering solution is just another marketing ploy, which aims only to increase the price of the product without improving its functionality?

Constant flame modulation

Gorenje gas-fired instantaneous water heaters are equipped with permanent flame modulation function. Despite the fact that this technology is often used in modern gas equipment, not all users know about it. So in this article we decided to explain what is the permanent modulation of burner flame, and what are its benefits.
