The best gas water heaters for 2020

For more than a century, gas water heaters have been heating water in our homes, providing a decent level of comfort and hygiene. Despite the development of centralized hot water supply, they have not lost their popularity, helping our citizens to survive seasonal and emergency hot water outages without losses. They are no less in demand among summer residents and owners of country houses. The editorial staff of the site "bestx.htgetrid.com/en/" offers readers an overview of the best gas water heaters for 2020 ", based on customer reviews and expert recommendations.

How it all began

The main components of the comfort of a human home have been and remain warmth and a sufficient amount of hot water. First, the water was heated in wooden containers, dipping stones red-hot in the fire into it. Over time, wooden barrels were replaced with copper, bronze, and then steel cauldrons, filling them with water and making a fire under them. The process went more fun, but you can't heat a lot of water like that, and it cools down very quickly. And the man called for help from solar energy.

Solar heaters

From ancient times to the present day, residents of hot countries have heated water using the thermal energy of the sun. In the 13th century, solar water heaters were already in use, having something in common with similar modern models. The Swiss scientist Horace de Saussure succeeded in 1760 to create a solar water heater with a glass top and a black body, which heated water to 100 ° C. However, the mass production of such devices began 130 years later in the United States, thanks to the inventor from Baltimore Clarence Kemp, who patented in 1891 his own version of a solar water heater.

Kemp's device consisted of the same black-walled glass box housed in an insulated box to keep warm. The water heater was so successful that over the next 18 years, Kemp's machines were snapped up by the residents of Southern California like hot cakes.

In 1909, William Bailey succeeded in improving Kemp's apparatus. The water in the new device was heated in copper pipes placed in the same glass box, and then drained into an insulated tank located below the heater.

The performance of the Bailey apparatus was lower, but it kept the temperature much longer. The new device supplanted the Kemp heaters. Over the next 10 years, Bailey sold several thousand of his heaters.

Soon, natural gas production began in California. Thanks to the assertive policies of the gas companies, solar heaters soon lost their appeal. Bailey managed to sell his production to sunny Florida, where solar heaters were in price until 1946. By this time, the cost of electricity had dropped. The sales of electric boilers increased accordingly. Although interest in solar vehicles has increased from time to time.In some countries: Japan, Israel, Cyprus, solar heaters are widely used today, along with electric and gas water heaters. Their only drawback is their climatic dependence.

Heat pump

We know from the school physics course that the temperature of absolute zero is minus 273 degrees Celsius. It is also known that no body in its natural state can be brought to such a deep freeze, although similar indicators were obtained in laboratories. If the body temperature is higher than absolute zero, then it has a reserve of thermal energy, which is the greater, the greater the body weight and its heat capacity. This is the basis of the principle of operation of the heat pump. The reserves of thermal energy of the earth (soil) of rivers and lakes, air, i.e. everything that surrounds us.

A simple example of a heat pump is any household refrigerator in the kitchen that uses freon as a refrigerant. Compressed by the compressor, freon boils and evaporates, taking heat from the air in the chamber, and then giving it to the environment through the condenser tubes on the back of the apparatus.

As an experiment, in the USSR, whole villages were heated and supplied with hot water by heat pumps.

Gas water heaters

Since the climate in Germany did not provide an opportunity for the efficient use of solar energy for household needs, it was here that gas instantaneous water heaters were developed.

Interesting! In 1892, a calorimeter was patented by a professor at the University of Aachen, Hugo Junkers. The ideas used in it served as the impetus for the creation of a gas water heater. In the same year, his company began to produce gas water heaters. A talented engineer, Junkers took up aircraft construction, first civil, then military. His airline Junkers Luftverkehrs later became Lufthansa. The production of water heaters was sold to Bosch.

In 1895, another talented German engineer, Johann Weillant, developed and patented Europe's first gas water heater, the Vaillant Geyzer. It was the Vaillant company, in addition to floor-standing models, that first set up the production of wall-mounted speakers back in 1905. At first, water heaters were made of copper, including the body. Then Vaillant switched to the production of water heaters in enamelled casings. For many years the company has become a trendsetter in the production of equipment of this type. Modern devices are structurally almost indistinguishable from the first Vaillant and Junkers models. The only difference is in the greater number of security systems and in the level of automation.

In the USSR, mass production of VPG began in 1956. The country was experiencing a construction boom that coincided with the gasification of cities. Citizens moved from rooms in communal apartments to separate apartments with a bath and shower. Columns of the KGI-56 and VPG type were produced in Moscow and Leningrad. The gas in these devices was ignited with matches, the main torch was manually regulated, the pilot torch burned constantly. From the safety automatics, protection against flame extinguishing and turning on the burner without water took place.

The first protection was realized by a bimetallic plate mechanically connected to the membrane gas supply valve. While the torch was burning, the heated bimetallic plate flexed and pushed down the gas valve stem, opening the gas passage. When the torch went out, the plate cooled down, straightened, pulled the stem up and the valve closed. All ingenious is simple!

The protection against working without water worked in about the same way. Before igniting the burner, the water tap was opened to the flow. The water pressed against the water valve membrane, which pushed the stem connected to the gas valve membrane and opened the gas passage to the burner. After that, the igniter was ignited with a match. If the water in the pipes "ran out" for any reason, the pressure under the membrane of the water valve dropped, the membrane returned to its place and pulled the valve stem, interrupting the fuel supply.

Soviet speakers did not shine with beauty, were easy to use and not as safe as modern devices, but they were distinguished by their strength and endurance. Some examples continue to work today, although their replacement should have been made long ago.

Interesting! In the USSR, people called gas heaters columns. In those days, in parallel with the indoor drinking water pipelines, there were still street pipelines with water-folding devices, which were called columns. By analogy with them, gas heaters also got their nickname.

Gas water heater device

Gas flowing water heaters (hereinafter referred to as VPG) are divided by the type of combustion chamber into the following types:

• with an open combustion chamber;
• with a closed camera.

To understand these concepts, remember that the combustion process of fuel is oxidative, i.e. flows only if there is a sufficient amount of air, or rather oxygen in the air. In an open chamber HSG, air enters the burner through an inspection window. Fuel combustion products are removed through the chimney into a special ventilation duct in the wall, or just outside. The air heated in the combustion chamber rushes upward together with the gases, since it is lighter than cold air. So in installations with an open chamber (so-called chimney columns), a natural draft is formed, which ensures the supply of cold air to the torch and the removal of smoke.

Traction sensor

Lack of traction is dangerous for gas-consuming equipment because, with a lack of air, the fuel does not burn completely, emitting carbon monoxide or carbon monoxide (CO) into the atmosphere. Its accumulation can lead to poisoning and cause death. In addition, the explosiveness of CO is much higher than that of natural gas. The appearance of a spark in a CO accumulation will inevitably end in an explosion. To avoid this, all modern HSGs are equipped with draft sensors, which are a thermostat designed for a specific gas temperature (indicated on the sensor body). With normal draft, the gas will not heat up above the set value. If this happens, then something is wrong with the thrust, it has decreased and the gas overheated. The sensor contacts open, the gas supply valve closes.

In HSGs with a closed combustion chamber, the air supply to the burner and the exhaust of fuel combustion products are provided by an integrated fan, therefore, devices of this type are called turbocharged.

Here the draft sensor no longer monitors the temperature, but the waste gas flow rate. If the gas flow presses on the sensor membrane with a predetermined force, its contacts remain closed, the gas valve is open, and the burner operates. As soon as the pressure is weakened, the membrane straightens and opens the contacts, the valve closes, the burner goes out. In turbocharged versions, a pressure switch is used as a thrust sensor. This is the name of a device for closing and opening electrical circuits for controlling equipment, which responds to a change in the value of a given pressure in pipelines.

Composition of HSG equipment

Wall-mounted VPG consists of the following units and parts:

1. Housing with removable bezel. It contains a viewing window, a display with a connection to the power supply, voltage of 220 V, a handle for regulating the supply of gas and water, an electric ignition button.
2. Inlet and outlet water connections. Hoses or metal hoses are connected to them, supplying cold water to the device, and heated to the consumer (tap or mixer).
3. Gas connection. An internal gas pipeline is connected to it with a hose.
4. Water and gas unit. Designed to regulate the supply of gas and water to the device.
5. Burner. Heats the water in the heat exchanger tubes.
   6. Ignition electrode. A spark discharge from it ignites the fuel.
6. Gas control unit (ionization electrode or thermocouple). Responsible for stopping the gas supply in the absence of flame. This is a security system.
7. Heat exchanger. Its pipes are heated by the flame of the burner and give off heat to the water.
8. Temperature sensor. Installed at the water outlet of the heat exchanger.
9. Diffuser. Installed in chimney HSG. Designed for catching and directing waste gas into the chimney.A thrust sensor is installed on the side of its wall. The upper end of the diffuser is designed to be connected to the chimney. Not available in the turbocharged version. In its place is a fan.

How HSV works

Water is supplied to the inlet and flows to the water valve. The mixer tap is open. The water pressure acts on the water valve diaphragm, which is mechanically connected to the gas valve stem, and opens it. Gas is supplied to the burner. In machines with mechanical control, at this time the electric ignition button is manually pressed. The spark from the ignition electrode ignites the fuel. If the system is functioning normally, the burner starts heating the water in the heat exchanger tubes. The display shows the rise in temperature.

In an electronically controlled HSV, everything happens automatically. As soon as the tap of the mixer is opened, the ignition electrode will immediately work, the gas will ignite and the device will work in full force. And if another tap opens at this time, the automation will increase the gas supply to the burner in order to maintain the set temperature. When one valve remains in operation again, the gas supply will automatically decrease and overheating will not occur.

Criteria for choosing a gas column

Choosing a high-quality HSG (gas flowing water heater) is not an easy task. Here are some of the most important criteria to help you avoid making mistakes:

1. If the manufacturer is reputable, he must have a website. Visit it, learn more about the company, its products, read customer reviews. If the manufacturer does not have a website, it is better not to consider its models.
2. Don't buy expensive European models. They can, like less top models, fail, but spare parts for them cost like other budget models.
3. Determine the required HSV performance for your option. If you are interested in heating water for one source, shower or kitchen mixer, it is enough to choose a column with a capacity of 10 l / min. Relying on two water intakes working at the same time (shower and kitchen), the device should be chosen performance. 13 l / min. Not a bad option for your own home. If you have a large house with two bathrooms and a kitchen, and simultaneous analysis from three points is possible, you will have to buy a 15 l / min device. The devices are 10 liters cheaper than the others, and this performance is quite enough for a family of 3-4 people, if the hot water is disassembled from one, maximum of two points (for a short time). You can save on this.
4. Modern HSVs are equipped with several security systems. The presence of a gas control function, a thrust sensor, overheating protection is required. Advanced models are equipped with a heat exchanger frost protection system in winter and flame modulation. The more security systems the better.
5. Choose devices with piezo ignition. This saves you the trouble of changing batteries in a timely manner.
6. Heat exchanger material. There are three options: galvanized steel, copper, stainless steel. The galvanized coating will burn out sooner or later. In addition, galvanized heat exchangers are usually thinner than others. Stainless heat exchangers are more durable, but their heat transfer characteristics are the lowest. To heat water in them, you need to bring the burner to maximum mode, and this is an overconsumption of fuel. You need to choose an installation with a copper heat exchanger.
7. There are a lot of manufacturers, the names of some companies do not say anything, no one has heard anything about them, and reviews of their products cannot be found. In order not to buy outright junk, buy HSV from well-known and best manufacturers.

Which company is the best water heater to buy

The question is rhetorical. Of course, it differs from well-known manufacturers, the popularity of models of which is time-tested and based on innovative technologies, the highest quality of components and assembly, differs in economy, environmental friendliness, safety and stylish design. An example of this is well-known European brands:

Vaillant

The oldest German company.She is the pioneer in the design and manufacture of Europe's first instantaneous gas water heater (patent dated 1894), the first temperature-controlled heater, the first wall heater (1905). Since then, only materials and a safety system have changed in the designs of gas water heaters. The principle of operation and schemes remained the same as they were developed by the specialists of Vaillant, the ancestor of European gas water heaters.

Bosch

Instantaneous water heaters of the brand will satisfy the client with any level of income. There are simple, inexpensive and very popular manual models like the Term 200 and top models like the Term 6000, equipped with electronic controls, automatic engagement and hydrodynamic power control. Common to the entire line is quality, reliability and durability. The motto of the company, since its foundation: “It's better to lose money than client's trust”.

Roda

 

Translated from Swedish "red". This is the name of a young company founded by a German engineer with Swedish roots, Olbak Holger, in Dortmund in 1982. In a short time, the company has developed and released a number of innovative models of burners, boilers and became a trademark. Today Rёda is one of the leaders in the production of climatic equipment: boilers, boilers, water heaters, radiators.

Gorenje

The models of the Slovenian brand are distinguished by simplicity, reliability, ease of use and an affordable price with a consistently high quality of assembly and components.

Ariston

Household equipment of a well-known Italian company does not need additional advertising. VPGs from Ariston are distinguished by wide functionality, stylish design, constant implementation of innovative technologies.

BaltGaz

The trade mark belongs to the company Neva, St. Petersburg. VPG is produced by the Armavir Gas Equipment Plant. BaltGaz models are designed for the CIS market, adapted to work with low water pressure. Their distinctive features are high-quality oxygen-free copper heat exchangers, ease of operation and safe operation.

Hyundai

Stylish design, innovative technologies, high build quality, reliability and durability are all that the products of the South Korean brand, one of the recognized leaders in the production of household appliances, are famous for. The company's specialists see their main task as improving the living standards of consumers through continuous improvement of the quality and functionality of their products.

The list of quality HSV producers goes on and on. Before you buy a gas water heater, find out what they are in terms of power and performance, how much this or that model costs and how to install it. However, installing HSV with your own hands is undesirable. For this, there are trained personnel who will competently perform all the work in compliance with all safety standards and rules and the execution of the relevant documents.

When choosing a water heater for a price, do not forget about quality. You can find inexpensive and reliable apparatus, semi-automatic or manual control. Listen to the advice and recommendations of experienced users, study the description of the water heater and its technical characteristics. Visit the manufacturer's website and find out as much as possible about your model, so as not to regret later on the funds thrown into the wind.

What else to pay attention to

1. Pay attention to the manufacturer's warranty periods. A serious manufacturer guarantees the trouble-free operation of its products for at least two years.
2. The weight of the device is important. If it is so light that you pick it up with almost one finger, it is most likely made of a very thin metal, almost foil. Such a device will not work for a long time.
3. Some buyers rely on their scent when choosing a water heater, in the truest sense of the word. If the item smells like cheap plastic, don't take it. They seem to be right.
4. Carefully review the documentation and the product passport, which should indicate the place of its manufacture, clear and understandable. If you don't find such information, it is better not to buy it.
5. The operating instructions for the HSV should be in Russian, clear and intelligible.
6. Some manufacturers declare the ability to work on liquefied gas for their models. This position requires clarification. This feature is generally not supported.
