Gas burner without chimney

It is now considered standard for human habitation for a home or apartment to have heated water. The only thing left to decide is which appliance will heat water for apartments in cities or homes outside of them the most efficiently. All residents who use the gas heater should be able to get hot water whenever they need it, and it should be easy to operate. Depending on the situation, a storage-equipped gas water heater or a flow water heater will be a more cost-effective choice.

Chimney-free gas heater

An economical and practical option is a gas-fired heater that doesn’t require a chimney; these units, also known as turbo heaters, are ideal for apartments located in multi-story buildings.

Design of a chimneyless gas heater

An extra chimney does not need to be built for such a heater to function because the water is heated by the energy released from combustion gas. It can run on liquefied or natural gas from cylinders or the home network.

Overview of the column device

A column like this doesn’t require a typical vertical chimney because it operates on the theory of combustion product exhaust. This water heater’s combustion chamber is set up hermetically, and a coaxial chimney is installed to allow gases to escape. The chimney is connected to the street directly through the wall. When a chimneyless stove is installed, a hole is immediately made in one of the walls. The heater has an integrated special fan that guides the combustion products in the desired direction.

The layout of the coaxial pipe directs the exhaust gases out of the inner section into the street, while the outer channel supplies the clean air needed for combustion.

Another benefit of having such an appliance is that it doesn’t dry out the air in the room and doesn’t require setting up a second air source to facilitate combustion. The possibility of significant cost savings on material purchases and installation work exists because there is no need to build a separate vertical chimney.

Although it will cost a little extra, Selena SE 3 can also operate on propane by retrofitting the column with specialized technical devices that will make it "omnivorous" and particularly indifferent to the gas quality!

Water heater parameters

An approximate operating scheme for gas heaters

Selecting a smokeless column requires consideration of a number of factors, including power, device performance, safety level, ignition type, and burner type. The appliance’s placement—horizontally or vertically—matters because the columns have distinct arrangements for the combustion product removal systems.

Ability

The performance of the water heater will be determined by the power that is correctly chosen. It is safe to say that power is the primary factor to consider when purchasing a water heater. In the flow heating mode, a higher volume of heated water can be achieved due to the high power level.

Achievement

The device’s capacity, or the volume of hot water the flow heater can produce in a minute of operation while accounting for a specific rise in water temperature, must be mentioned on the package or in the operating instructions.

For instance, the user will receive 14 liters of hot water in a minute if the temperature is set to 25 degrees, according to the instructions. In the event that the water is 8 degrees at the heater’s inlet, the device’s operation causes the temperature to rise by an additional 25 degrees, reaching 33 degrees at the outlet.

You are welcome to perform the calculation on your own; the manufacturer’s specified power figure is divided by two for this purpose. The volume of water that the column dispenses, heated to between 26 and 32 degrees Celsius, will be the outcome of a reasonably accurate calculation. A water heater that is intended to provide 14 liters per minute, for instance, will have a capacity of 28 to 30 kW.

It is important to consider that for showering, washing, or dishwashing, 5.5 to 6 liters per minute per water extraction point is more than sufficient when selecting a water heater.

A smokeless water heater being turned on

Piezo, electric, and hydroturbine ignition systems are the three types of ignition systems installed on contemporary water heaters that don’t have a conventional chimney. They guarantee that using the heater is safe and simple.

• Hydroturbine ignition is from a hydrodynamic generator. Some modern gas water heaters are equipped with mini-hydroelectric power plants, the generator of which is built into the water heater piping. When water is supplied, it passes through the turbine, rotates its blades, and the generator produces the required electrical potential for the igniter. These water heaters do not need additional energy sources for ignition.
• Piezo ignition has a special element that produces an electric potential from mechanical action, which produces a spark that ignites the burner. With this kind of ignition there is one inconvenience, which will not allow you to save on gas fuel – the igniter must be in a burning state in advance so that the main burner will light up when the water is turned on.
• Electric ignition requires connecting the heater to the mains or installing batteries or accumulators. The water pressure sensor is activated when the tap is opened and gives the command to ignite the igniter by means of a spark arrester.

Smoke-free heater control system

There are two types of burners: open and closed.

These water heaters have a variable (automatic) or constant burner flame control with stepped output.

• Boilers with burners, regulated automatically, after setting the temperature mode will work stably, giving water of a specific temperature at the outlet, regardless of external influences. As a rule, it is an electronic push-button system with digital indication.
• Water heaters with staggered burners allow you to adjust the burner flame, and therefore the water temperature, independently. Once installed, however, there is no guarantee that the heater will continue to operate in this mode, as the gas pressure, the temperature of the incoming cold water and even changes in atmospheric pressure can affect the heating of the water.

You can change the temperature by rotating the tap knob in either direction. Avoid overtightening the knob to avoid the unintended consequence of the water heater completely shutting off. Combining hot water from the heater with cold water from the tap is a very bad idea.

Safety of Smokeless Water Heaters

The majority of customers believe that smokeless columns are totally safe to use, but is this really the case? For the safe use of any gas-powered appliance, prudence and regulations are necessary.

The column is automatically turned off in the event that a water heater element fails or the coolant overheats. This justification may support the device’s enhanced safety provided that it is installed correctly and by a trained professional.

However, the coaxial pipe, which removes the combustion products from the heater, may become dangerous for the occupants of the upper floors if a smokeless heater is installed in a multi-story apartment and there are multiple floors above the apartment. After exiting the pipe, carbon monoxide rises and is easily propelled upward by air currents, which can have catastrophic effects if it gets into an open window or even the upper apartment vent.

The coaxial pipe outlet on the street appears like this.

This is the reason that before installing any kind of water heating equipment, you should always speak with a gas utility. When living in an apartment on the top floor or in a private home, you can set up a smoke-free heater without risk to the neighboring residents.

Smokeless heater looks great in the interior

We would like to discuss briefly the location of the chimney-free column inside the apartment. If the kitchen or bathroom has at least one wall that faces the street, it can be placed there; however, a hole for the coaxial pipe must be made. There won’t be any issues with the water heater installation if such a possibility exists. One benefit of these columns is that they do not have ugly chimney pipes that occasionally adorn the walls.

The interior harmony shouldn’t be disturbed by the speaker.

The wall-mounted water heater maintains its neat appearance, doesn’t deteriorate, and occasionally even adds to the interior design.

Make sure you consider the advantages and disadvantages of this pricey but essential appliance before making your purchase and figure out where to put it. Consider alternative kinds of water heaters if even one condition raises questions.
