TOP 15 best floor-standing gas boilers: Rating 2021-2022 and which double-circuit or single-circuit model to choose for heating a private home

They are also configured to automatically turn off if there is no draft in the chimney.

Such boilers are installed when the power supply is unstable. The chimney for a floor-standing gas boiler is an important element that must be taken into account when installing the boiler.

Some gas boilers require an ordinary chimney, while others require the installation of a coaxial one. Therefore, before installing the chimney, you need to carefully read the instructions for the gas boiler. With some boiler models, the chimney is already included. Conventional chimneys lead upward, but a coaxial chimney leads into the wall, as it is mounted horizontally.

Some experts argue that it is better to purchase boilers that only work to heat the room, without heating water, considering heating water with a boiler to be economically unprofitable. And some, on the contrary, believe that boilers with DHW mode are a profitable investment.

What to consider when choosing a boiler

There are gas boilers with one and two circuits. The difference between them is that a double-circuit boiler combines two functions at the same time: it heats the room and provides hot water. A single-circuit boiler, accordingly, performs only one of these functions - heat supply.

A double-circuit boiler is a more convenient and economical option, as it is used as a home heater and replaces a water heating column. The boiler can be connected to both a single-circuit and a double-circuit boiler.

What should you pay attention to before choosing a floor-standing gas boiler and what parameters should you take into account? The main thing that needs to be considered is the conditions for placing the boiler and the power of its operation.

The boiler is connected to the boiler if high water consumption is expected and it is necessary to heat a large space.

The boiler extends the “life” of the boiler, improves its operating mode and perfectly withstands constant temperature changes. The capacity of built-in boilers can be from 40 to 100 liters. When installing a boiler, it is necessary to install cleaning filters that prevent the appearance of scale.

Gas floor heating boilers with a built-in boiler are used for hot water supply and heating. The coolant is process water. A floor-standing gas boiler has its negative and positive characteristics.

Gas floor heating boilers have a long service life and have no power limitations. Such boilers have a fairly high cost of the boiler itself and its equipment.

Floor-standing gas boilers with a boiler are a system with the help of which not only heating, but also hot water supply is organized at no extra cost. Almost all modern boiler models provide a DHW mode and automatic switching of modes from heating to DHW. Such a boiler is capable of supplying water to a family of up to 6 people and heating large areas.

How to choose a floor-standing gas boiler?

Focus on the following parameters:

• Power. An average power reserve will allow the boiler to last not 1 or 2 years, but significantly longer. Add 25% to the optimal power indicator, and the result will be the very figure from which you should build.
• Material of manufacture. Gas boilers made of cast iron last the longest. But get ready to shell out a hefty sum for such a boiler.
• Device type. A condensing boiler is cheaper and more economical.
• Control. Choose a model with manual temperature control: sooner or later you will want to choose the appropriate indicators yourself.
• Safety. The boiler must have protection systems: gas control (which turns off the unit if there is a gas leak), protection against hypothermia and overheating.

Buying a boiler with a boiler in the Termona-Rus store

Before buying a gas boiler with a built-in or separate boiler, we recommend that you seek advice from specialists. They will help you choose the type of boiler and boiler, their power, volume, additional options, and control methods.

Lemax Premium-16

Italian boiler automation Lemax Premium is a guarantee of a long service life of the boiler without failures or problems. Modern boiler protection - gives complete confidence that its protection will work in the event of overheating, interruption of draft, soot formation or blowing out of the boiler. The boiler does not depend on electricity - this is the ability of the boiler to operate when the electricity is turned off. All these indicators are important to me, so I installed a Lemax Premium boiler and in 2 years I have not regretted my choice at all!

Evgeny A.

BAXI SLIM 1.230 iN, 22.1 kW

Pros: Well made! Will fit into any interior if there is no boiler room. There is access from all sides. Cast iron! Working with an indirect heating boiler. Disadvantages: It is inconvenient to connect the upper supply pipe. The thread is also internal. Doesn’t keep the flame on the socket, constantly ignites it... resulting in unusually audible popping noises every time it starts.

Ivan Chirkov

Lemax Premium-10

I installed Lemax Premium at the end of last summer. Just a couple of years ago I wouldn’t have even looked at it. Before it there was an expensive but popular unit. And I understand very well those who say that Europe is doing great. Yes it is. And when everything is fine with your expensive boiler, you live and don’t give a damn. But as soon as problems appear, that’s it. Do you know how much it costs to change a heat exchanger or automatic ignition? Yes, it’s easier to install a new boiler. I had no illusions about Lemax, but at least I knew that if something happened they would help me, our service technicians know our products better and spare parts are always within easy reach. That's why I took the course that it would be cheaper to maintain. There is little to say about the boiler itself yet. It works and doesn't make any noise. At first I was confused by the condensation that appears when it warms up to 50 degrees. But the support service assured that this was normal for such a temperature, and I myself later saw in the passport that this was written. Pah-pah, let it continue to work.

Roman Belov

Lemax Premium-20

I tried to find a powerful and compact gas boiler. For my 180 square meters (2 floors and an attic) I picked up Lemax-premium for 20 kW. During the first heating season, it seemed that I paid a lot on gas. It’s easy to control: I set it to 5-6, that is, up to 80 degrees. The boiler was ticking. But it was warm. This season I thought about saving, but the craftsmen shrugged their shoulders, saying the settings were correct. Only the neighbor came up with the idea to insulate the walls so that the warmth would remain inside. When I had already completed 2 rooms, less gas began to escape.

Klochkov Oleg

Siberia 17, 17.4 kW

An excellent boiler for the money, very heavy, more than 50 kg, which speaks of the thickness and durability of the heat exchanger steel. Piezo ignition, flame control, maintaining and regulating the set temperature using the best Italian mechanical automation. With a well-made heating system, this boiler will last a lifetime, which will not have to be repaired or even maintained.

Elena S.

Lemax Premium-10

Problems with commissioning initially spoiled the impression of Lemax. The burner went out, it was an infection. I later found out that it was due to pressure. I called the Lemax hotline, and that’s what they answered. And it seems like the gas pressure is written down in the passport, right? But the gas was still not adjusted properly, the pressure was lower, the burner went out. And so I chose a simple boiler without unnecessary automation, so that no power surges would “eat up” my brain, but here is such a setup. I had to invite the gas workers, but they screwed it up and that’s it, and it doesn’t matter that I suffered for a week

Nikolay V.

Lemax Premium-30B

Last year we selected a gas boiler for heating. We looked at more than one option and chose the Lemax Premium-30V boiler. We consulted with neighbors and gas workers. We looked on the Internet. Lemax is produced in Russia. This means they are adapted to our Russian realities, unlike imported ones. This is a floor-standing, double-circuit boiler with an open combustion chamber; combustion products are removed naturally through the chimney. It will heat the house and heat the water. Electronic control. The quality is top notch. This is confirmed by those who already use such boilers and those who service them. The boilers are reliable, and if something happens, they are repairable. Spare parts are always available and at low prices compared to imported ones. We ourselves were convinced of the quality of the boiler. Last winter, and it was frosty, he proved himself to be the best.

Lemax Premium-10

I installed it in the fall, at first when I started it for the first time there was something rustling inside, I thought it was a leaky heat exchanger, but everything went well - just factory paint and condensation. There was a problem: the gas went out. We figured it out - it turned out that because the exhaust pipe was made of asbestos and there was no insulation, the exhaust hood was weak and disappeared, so the automation was triggered and plus condensation formed. I insulated the pipe and the problem disappeared. For a log house of 60 m in position 3, the temperature in the house is 24 degrees while the outside temperature is -20.

Ksenia S.

Lemax Premium-30B

I specifically took a boiler from Lemax for a private home, because I already had a bitter experience with imported ones - they focus on the milder European climate, but here we have even -20, sorry. I heard only good things about the manufacturer, and a colleague advised my husband that he has Lemax, only a different model. This particular model suited us, the house is 200 m2, it is enough for him with a margin, and it is also efficient in terms of gas consumption. We haven’t regretted it even once; finally we don’t freeze in winter. It was installed for us by invited gas workers) and they did it quickly. The only thing is that it’s really, as they wrote here, a little noisy (it’s not really critical for me, but suddenly for someone it will be a problem.

Rules for choosing a gas double-circuit floor-standing boiler

The power of the unit is an important indicator when purchasing, but there are many more characteristics that should not be forgotten, these include:

1. How much gas is consumed?
2. Efficiency
3. The performance of the circuit responsible for hot water.
4. If the equipment is volatile, then you need to find out the power consumption.
5. Indicators of maximum temperatures.
6. System pressure.

Thanks to a thorough study of the technology, you can determine a suitable copy from the many brands presented. By comparing the characteristics, it will be possible to identify significant shortcomings and positive aspects; it is equally important to take into account the opinion of the repair and service departments and the possibility of quick service.

Convection or condensation

Convection types of equipment cannot be called the most productive, because part of the heat released to heat the coolant simply goes into the atmosphere. Such units often have an efficiency rate of 85%; actual productivity rarely exceeds these figures.

The positive aspects are obvious: simplicity of design, low cost, compactness and ease of installation. Condensing types of gas double-circuit floor-standing units are much better, they are at least 20% more efficient, thanks to the installed additional heat exchanger, steam energy is used to heat the liquid. They will cost more, but these expenses will quickly pay for themselves, gas is consumed economically, and efficiency is at a high level.

Volatile or non-volatile

A device that operates from the network is not the most profitable option for installation, because the cost of electricity consumption will additionally fall on the owner of the building. Therefore, most consumers choose units of this type with class A++.

One cannot help but notice the high cost of spare parts, repairs and automation, because breakdowns can happen at the most inopportune moment. Failure of the board can rightfully be called a frequent occurrence; replacement will cost half the cost of the equipment; repairs are also expensive.

Non-volatile models operate on the principle of a gas stove, heating a tank of liquid; voltage drops and power outages are not a problem, since the double-circuit gas boiler operates autonomously.

It is necessary to foresee the location of heating devices in advance, since it is specific and the coolant circulates naturally.

Open combustion chamber or closed

Equipment with an open combustion chamber is considered the most economical, the efficiency indicator reaches 109%, air intake occurs due to gas combustion. The package includes two burners, one of them is the main burner, and the second is a pilot, the intensity of the main component can be adjusted with the burner, the pilot element operates in constant mode.

Devices with a closed combustion chamber cannot operate without forced draft, which makes them less practical. The intake of fresh air occurs thanks to this component; equipment of this type is often used in apartments to be built into a single furniture ensemble or installed using a special box.

Optimal gas consumption

You can calculate the minimum indicator by comparing several models with the same power. To calculate the amount of gas per 1 kW, you need to know the efficiency of the device and the calorific value of the fuel. Taking into account standard standards, in a regular main line the mixture has data that is 9.3 kW/cu. m. If the unit coefficient is 90%, then the generation of 1 kW will require 0.12 cubic meters. m. this is determined in this way: 9.3x90%, then 1/8.37.

Required power for floor-standing double-circuit gas boilers

This indicator is one of the important ones; when purchasing a device in a store, all visitors pay attention to the device’s passport data. There is no need to purchase equipment that is too powerful; this will entail high fuel consumption, which will affect the family budget.

If it is not enough, then there can be no talk of a comfortable temperature regime, or the equipment will constantly work on the verge of its limit and will soon fail.

There is a universal formula for calculation; it involves multiplying the specific power, which is calculated for each region of the country, by the square footage of the building, and the resulting result is divided by 10. Example: 200 sq. m. x 1.1 kW/10 = 22 kW. I take the middle band into account.

Data on climate zones looks like this:

1. Southern: 0.7-0.9 kW.
2. Middle band: 1.0-1.2 kW.
3. Moscow region: 1.2-1.5 kW.
4. Northern: 1.5-20 kW.

For the most accurate calculation, it is necessary to make adjustments taking into account the characteristics of the premises.

Heat exchanger

If a private building is located outside the city or is a cottage in which you do not plan to live permanently, then it would not be superfluous to provide protection against freezing of the system.

The most common liquid is antifreeze; it should be added to the line after calculating the number of liters. When temperatures drop, these substances prevent water from hardening, it goes into a gel-like state, and all connections and pipes remain intact.

Storage tank

Floor-standing double-circuit boilers with a built-in tank can ensure continuous operation of heating and hot water supply, especially if the liquid is planned to be used in large quantities. Flow-through types of equipment cannot boast of such technical characteristics.

The capacity of the container ranges from 25 to 60 liters, the power is selected taking into account operational needs. The built-in element serves to minimize temperature differences in the heating line, because part of the heat will be spent on heating the water.

Smoke removal process

If the building has an existing chimney, you can connect to it to reduce waste. There are several options; to implement the plan, a hole is made in the ceiling or wall; it is important to ensure the correct assembly of the components, this will protect against the occurrence of various excesses.

The mechanism of action will require a separate room for installation, the boiler room should be equipped according to all the rules, and to enhance the effect, most owners install forced fans.

Efficiency

This data can be found in the passport for the device; the efficiency of blue fuel and the comfort of the premises depend on it. The higher the indicator, the more efficiently the device will work; according to many people, in reality the situation is different, but I advise you to pay attention to these characteristics. Condensing types of boilers for heating a private home will be the best in this indicator, their data is often 98% or higher.
