Gas column or boiler – which is better to choose to get hot water

Selecting a hot water supply for your house—a gas column or a boiler—can be a big choice with long-term effects. Evaluating your unique needs and situation is crucial before choosing between the two options because each has pros and cons of its own.

Tankless water heaters, sometimes referred to as gas columns, are small, effective units that heat water as needed. Gas columns heat water as it passes through the unit, as opposed to conventional water heaters, which hold hot water in a tank. Gas columns are an appealing option for homes with high hot water demand since you’ll never run out of hot water.

Conversely, boilers are central heating systems that heat your house in addition to providing hot water for domestic use. Warming living spaces, hot water from boilers is circulated through underfloor heating systems or radiators using a closed-loop system. Boilers provide uniform heating throughout your house and can ultimately be more energy-efficient, even though they do require more space and an initial financial outlay.

Think about things like your hot water usage habits, the amount of space you have in your house, upfront costs, and your energy efficiency objectives when choosing between a gas column and a boiler. Furthermore, consider whether you value multifunctionality or a constant supply of hot water, as boilers can meet both heating and hot water demands.

Types of water heaters and criteria for their comparison

The two categories of water heating appliances for residential use are cumulative boilers and running water columns. The former are a set-volume tank where water is heated in different ways until it reaches a maximum temperature of 75 °C, at which point it is ready for use. The columns that are also the running heaters are made to raise the temperature of the flow through the heat exchanger "on the move."

Three types of hot water vehicles for homes and apartments are available for purchase in stores:

• electric and gas columns for water;
• cumulative boilers operating on electricity or natural gas;
• Boilers of indirect heating.

Since these two types are the most common, people are typically curious about which is preferable: an electric water heater or a gas column.

It’s really not that hard to become popular. These are better than other household appliances because they are more affordable, more dependable, and more efficient. An electric column is more difficult to install and requires more power, so it shouldn’t be placed in an apartment with outdated wiring or a low electricity limit.

It is also impossible to classify a gas storage water heater as a necessary home appliance. Utilizing the column is more convenient, and placing it is simpler. Conversely, a heating boiler is utilized in conjunction with the accumulative boiler for indirect heating. These DHW tanks come in two sizes—floor and wall—and can hold between 100 and 300 liters. They are large and require a lot of room.

When comparing a gas column and an electric boiler, we will establish three standards:

• The price of equipment;
• complexity of installation;
• Ease of use.

However, it doesn’t hurt to learn about all the benefits and drawbacks of these hot water heaters initially.

Pros and cons of electric boilers

These devices work on the following principle: an electric heating element heats the entire volume of water in the tank to the user-specified temperature. Its maximum temperature is 75 °C, and its ideal value is 55 °C. Depending on the starting temperature in the water supply, heating from zero takes one to three hours.

Upon reaching the maximum temperature threshold, an electric boiler can promptly supply a substantial amount of hot water upon request from multiple users. The tank’s capacity and the cost of consumption determine how long the cooling process will take. In light of these characteristics, the following are some advantages of the electrically powered storage heaters:

1. The ability to satisfy a request for a large water consumption simultaneously from several consumers.
2. The operation of the apparatus does not depend on the pressure in the water supply and the initial water temperature.
3. Installing and connecting a boiler is much easier than any other water heater. No permits are required for installation, chimney channels and ventilation with a three -time air exchange are also not needed.
4. Long service life. In most models, from different manufacturers of TEN, the ceramic shell is protected and will not burn out from the formation of scale.

Citation. Electric heaters have historically had the highest theoretical efficiency—99%. Though it is challenging to assess this benefit in practice when compared to a gas column.

The storage-type water heater’s drawbacks include its inability to supply hot water in its entirety and its propensity to take a long time to heat the next section after the tank’s supply has been used up. Two choices are available if the boiler is chosen incorrectly in terms of volume, which can worsen the disadvantage:

• The device with a too spacious tank heats up longer, and in the duty mode consumes more electricity for nothing;
• A small container is an insufficient supply of hot water, which will not be enough for all the needs and you will have to constantly expect a new portion to warm up.

The accumulative tank’s size, which is a major factor in the apartment, is the final major drawback. Finding space in the kitchen or bathroom for a device with an 80-liter capacity is difficult because roughly 4 people would require such a volume.

Advantages and disadvantages of gas columns

The capacity to temporarily heat water by simply opening the corresponding crane on the mixer is the prototype type of domestic gas water heaters’ strongest feature.

In addition, the valve remains open for an infinite amount of time, allowing the column to continuously supply hot water. These characteristics are what draw users’ attention to running gas heaters.

We also consider additional benefits of gas stems:

1. Models with an open combustion chamber do not depend on the supply of electricity.
2. Turned devices with a closed camera are economical and effective because they are equipped with a multi -stage or modulating burner, whose power is adjusted in automatic mode depending on the load.
3. The gas heater takes up slightly space due to small sizes. Harmoniously entering it into the interior of any kitchen is not a problem.

Electric heaters are more efficient than even the best columns. They are not more efficient than 90%, though in actual use this is barely noticeable.

You might wonder why so many owners of homes and apartments choose to install electric boilers if gas water heaters are so great. This is because there are a few, but noticeable, disadvantages with the speakers:

1. The device gives the amount of water indicated in the passport, heated to a certain value (delta). For example, the Neva gas column 4511 with a capacity of 21 kW can provide a consumption of 11 l/min when heating water by 25 ° C. If there is water with a temperature of only 10 ° C into the house, then only one consumer is enough for its heating to 35 ° C. And with a 40 ° C delta, the consumption becomes much less – 7 l/min. To increase it to at least 8.5 l/min, you need a lot of power – 28 kW and a more expensive heater.
2. You can’t just buy a gas column, put and connect. It is necessary to coordinate the installation of gas -heating equipment with the management company and carry out the project, and to connect, hire an installation company, whose staff has the appropriate “crusts” and resolutions.
3. When burning gas, combustion products are formed, requiring diving into a chimney channel or through a coaxial pipe.
4. When the pressure falls in the water supply below a certain level, the water heater will be disconnected.

Now that you are aware of all the benefits and drawbacks, let’s select a hot water heater.

When it comes to deciding between a gas column and a boiler for heating water in your home, several factors come into play. Gas columns are generally more affordable and compact, making them suitable for smaller spaces or where installation space is limited. They heat water quickly and are easy to maintain. On the other hand, boilers are more efficient for larger homes or buildings with higher hot water demands. They can provide hot water to multiple outlets simultaneously and are often more energy-efficient in the long run. However, boilers require more space for installation and may involve higher initial costs. Ultimately, the choice between a gas column and a boiler depends on your specific needs, budget, and available space. Consulting with a heating professional can help you determine the best option for your home.

What to choose – a boiler or column

When selecting any product, the price is what typically gets the average user excited. However, the fundamental workings of an electric storage water heater and a gas column are entirely dissimilar. As a result, only one sign—the capacity to supply hot water to a family of three—can be used to compare their values.

For instance, we consider two reasonably dependable, mid-range appliances: a 50-liter Gorenje boiler and a flowing heater under the Neva brand. What resulted from it was that:

Observations:

1. If we take a gas column from the Gorenje brand for comparison, then it will cost even cheaper than Neva – about 135 at. e.
2. The table is given the electric power of the boiler, but it is almost equal to thermal.

In conclusion. A natural gas-powered water heating column wins hands-down in terms of equipment cost.

Comparison on the complexity of installation and connection

This criterion is significant because it is linked to both temporary and monetary costs. We won’t compare the eyeliner of hot and cold water because it is present in both situations. The comparative table describes the features of installing various water heaters:

In conclusion. Although there can be some challenges when installing a large, bulky boiler, connecting it is generally much simpler and less expensive. You can place the accumulative heater by yourself if you so choose.

Convenience during operation

After weighing all the benefits and drawbacks of using domestic water heating appliances, we will compile them into a single list:

1. The column heats the water immediately after the opening of the crane, which is very comfortable. The boiler for the preparation of water takes time – from 1 to 3 hours, depending on its temperature and the volume of the tank.
2. The drive gives a large expense and provides several consumers at once. During the water disposal at 2-3 points, the column does not have time to heat the water and its temperature drops.
3. The flow of the gas heater heats the water for an unlimited long. The duration of the feed on the boiler depends on its capacity.

When discussing operation, equipment maintenance should not be overlooked. The accumulative electric water heater is more dependable in this sense because it only requires routine anode replacement and tank cleaning. Gas speakers are complicated equipment that not everyone is able to maintain and repair.

In conclusion. When devices have sufficient thermal power to meet all requirements, using them is still more convenient. Another factor is upkeep and repairs; in this sense, the boiler’s content will be less expensive.

There are a few things to take into account when choosing between a boiler and a gas column for hot water in your house. Each option has advantages and disadvantages, and the best decision for you will rely on your unique requirements and situation.

Gas columns are renowned for being economical and efficient, especially for smaller homes or apartments with constrained space. Compared to boilers, they typically cost less to install and heat water more quickly. However, because they might find it difficult to maintain the necessary flow rate, gas columns might not be the best option for larger homes or households with high hot water demands.

Boilers, on the other hand, provide a more complete solution for heating the water and the house. They can be more energy-efficient in larger properties and supply multiple taps with consistently hot water at the same time. Boilers can be integrated with other heating systems for increased efficiency, but they are generally more expensive initially and may take up more space during installation.

When making a choice, it’s critical to take your hot water usage habits, available space, financial situation, and long-term heating requirements into account. You can evaluate your options and choose the best solution for your house by speaking with a qualified heating technician.

In conclusion, your unique needs and preferences will determine whether you select a boiler or a gas column for hot water. Before choosing, it’s important to carefully consider the benefits and drawbacks of each option. You can choose the best heating solution for your home by taking efficiency, space, and cost into consideration. This will guarantee comfort and convenience.
