Overview of double-circuit gas boilers Baxi

baksi, proterm or navien, what else would you recommend for 100 sq.m.

If you need a cheap boiler, then of course Proterm, if you decide to invest in an expensive one, then of course Vaillant (Proterm, a cheaper trademark of this manufacturer). It makes sense to buy a baxi only if it is sold to you very cheaply (there are huge discounts on them), from the advantages there is a good service network, but cheap models like Main For are rubbish!
Navn is generally a temporary cauldron, for the severe punishment of sinners! Everyone who has been handed it is ruined during operation and lose their nerves with constant and regular breakdowns, and the service is reduced to telephone advice and the sale of very expensive spare parts by mail.Therefore, many people throw away Navien without waiting for the end of the first heating season.
Viessmann boilers are absolute German quality and reliability, amazing survivability proven by many years of Russian operation, minus they are more expensive than all of the above.

How to choose a Baxi gas boiler?

The approximate power of the boilers is taken at the rate of 1 kW per 10 m2 of housing area. However, such calculations are very approximate and do not take into account the degree of insulation and heat loss through the windows. In addition, they are not suitable for double-circuit boilers also because it is necessary to lay down the power consumption for heating water.

Double-circuit boilers must be purchased if the house does not have hot water supply in principle. In case of seasonal and emergency shutdowns, it is better to purchase a separate water heater (flow or storage).

For hard water, it is advised to choose the ECO series, where the heat exchanger will not be as strongly affected as in other models.

A bit of history

The largest European holding BAXI Group was founded in England 150 years ago - in 1866. Today, more than three dozen specialized companies located on the territory of Western European countries are subordinate to him:

• England;
• France;
• Germany;
• Italy;
• Spain;
• Ireland;
• Denmark.

Each of the enterprises belongs to the sector of production related to heating equipment, but, nevertheless, there is some division. Some factories specialize in boiler equipment and water heaters, others in components and accessories, including automation and radiators, others in systems related to solar energy, and fourth in compact heat and power generators. Moreover, the united enterprises include a unit engaged exclusively in the development of advanced technologies with their subsequent introduction into the production cycle.

Russian consumers are familiar with the Italian branch of BAXI GROUP by the trade mark BAXI SPA. The manufacturing company has been producing heating equipment for more than half a century, including BAKSI gas heating boilers, although the factory was originally focused on the production of radiators and enamelware, and then bathtubs. The year of foundation of the enterprise is considered to be 1924, the location is Bassano del Grappa, a town in northern Italy, and the founders are the Westen family of Austrian origin. Since 1978, the company has changed its name more than once, entering into different, but specialized concerns, and since 1999, it has received its current name by joining the BAXI GROUP. Today, the Italian factory is the leading enterprise of the holding, producing gas heat generators. BAXI SPA was one of the first to deservedly receive an international quality certificate.

A whole network of company stores and service centers has been opened in Russia. Here you can get acquainted with BAKSI products and documentation, get advice and choose the right gas boiler. The equipment is certified according to European and Russian standards, which fully meets the requirements of the modern market.

The Baxi boiler works best on natural gas. This is a more affordable and acceptable means for all citizens at its cost. The efficiency of the Baksi heating boiler is almost 90 percent. This is by far the most rational choice for heating your home.

There are still a lot of technical characteristics of Baxi boilers. Of these, it can be noted: the Baksi electric boiler can work in any conditions, as it is made in accordance with modern standards of use. If the light is turned off at your house, then you can connect it to the generator - and the problem will be solved. A generator is a must, because in winter you don’t want to freeze without heating.

The Baxi boiler works stably and steadily, even despite fluctuations in gas pressure. The control system will allow you to properly adjust the operation of the boiler (temperature and pressure in the system).

Baxi floor standing condensing boilers have sensors that are made for safe operation. If there is no thrust that controls the flow of gas, then the Baxi boiler will immediately shut it off. Due to such a good operation of this unit, there will be no condensation effect.

Device

The device of the units does not have significant differences from analogues from other manufacturers or generally accepted schemes.

Baksi Slim boilers consist of the following units:

• Gas burner open or closed type.
• Sectional type heat exchanger made of cast iron.
• Circulation pump.
• Three-way valve.
• Expansion tank.
• Turbo blower.
• Control board and self-diagnosis sensor system.

The operation of the boiler is based on the process of heating the coolant and organizing its circulation. Heating is carried out in a heat exchanger, where the OV receives thermal energy from gas combustion.

The hot coolant passes through a three-way valve (mixing unit), where a colder return flow is mixed into it in a certain proportion.

It turns out the RH of the desired temperature, which is sent to the system. Hot water is supplied to the tapping points after passing through the heat exchanger.

Its temperature depends on the intensity of the analysis, the more the tap is open, the colder it is.

How double-circuit boilers Baksi are arranged

Baxi double-circuit boilers are designed for heating water in the heating and hot water circuits. In fact, such units are an improved single-circuit modification, implemented with a DHW boiler in the form of a conventional or bithermic heat exchanger. In the first case, the heat transfer in the DHW circuit occurs with a heated coolant coming from the heating boiler.

The bithermic heat exchanger does not stand out from the outside of a standard boiler boiler. Only inside the heating surfaces for heating and hot water are separated by tubes of a complex configuration, similar to a rhombus.

Water moves along the outer contour for heating, and inside the rhombus - for hot water supply. This design more effectively removes heat from the heating medium, but has problems when cleaning surfaces from scale.

Therefore, for such devices, it is mandatory to install filters for preliminary purification of make-up water with a softening function.

Advantages and disadvantages

The advantages of double-circuit boilers Baxi include:

• Organization of heating and hot water supply using one installation without the need to connect additional devices.
• High-quality assembly, compliance with all European standards.
• Environmentally friendly equipment.
• Adaptation to Russian technological conditions and climate features.
• The ability to independently determine and signal the occurrence of failures or failures of the installation nodes.
• Profitability, relatively low gas consumption with efficient and active work.

The disadvantages are:

• Dependence on the availability of electricity, on the quality of water.
• The high cost of boilers and spare parts.
• The inability to replace parts with analogues from other manufacturers.

NOTE!

Both advantages and disadvantages are included in the design features of all such installations, with rare and episodic exceptions.

Types and series

The manufacturer Baxi has a large volume of gas heating boilers, both wall-mounted and floor-standing. Wall-mounted, most often chosen for individual homes, are produced in three main lines, called Prime, Eco3 and Luna.

Heating boilers of the Luna series are equipped with two important systems: self-diagnosis and electronic modulation. In addition, there are two different temperature settings, which allows you to adjust the work to the existing conditions. The devices are double-circuit, and the prices for them are quite acceptable.

Boilers of the Prime series belong to the economical class. They have a closed combustion chamber made of composite materials, which contributes to the almost silent operation of the device.Prime units are condensing, have a biothermal heat exchanger that reduces gas consumption, and built-in useful systems: diagnostics and automation that respond to temperature fluctuations both under the roof and outside.

The Eco3 series is also compact, efficient and reliable. They are able to continue to work effectively with a sharp drop in pressure and automatically regulate the temperature of the water. They are happy with a decent price.

Modern models of Eco Four and Luna-3 Comfort boilers are very popular. Both units can be with an open or closed combustion chamber, inside which a copper heat exchanger is placed. Eco Four demonstrates performance from 14 to 24 kilowatts. It has a storage tank with a size of 6 liters and an automatic control system coordinated with an outdoor temperature sensor. Such a boiler can also be connected to other devices, such as a timer or thermostat. It is protected from changes due to temperature changes and is equipped with a smoke detector. In fact, this is a standard Baxi boiler in all respects, except for power - it is the least powerful device of the entire brand.

Luna-3 Comfort has a capacity of 24, 25 and 31 kilowatts. The storage capacity can be 8 or 10 liters, and the device itself is equipped with weather-dependent automation. It is worth clarifying that the kit includes a digital panel that can be removed and placed both on the boiler body and elsewhere.

Separately, it is worth talking about the models of the Main series, one of the most famous of which in the domestic market was the Main Four, which has been discontinued since 2017. By the way, the number in the name of the Baxi boilers indicates which generation the model belongs to.Such a device has a very compact size - it can be placed in almost any, even extremely limited space. There are two power options - 18 and 24 kilowatts, which is not considered an outstanding indicator. In addition, there is a display and a push-button control unit for the boiler. According to reviews, this makes the process of using the boiler very comfortable.

It was replaced by the Main Five model from the next generation. The device is completely the same as the previous release, but in addition it is equipped with a draft system in the chimney and a few more additions.

Baxi wall-mounted gas boilers are also double-circuit and single-circuit. Double-circuit models are responsible for performing two tasks: heating the house and providing hot water. Both tasks are carried out successfully, and the use of hot water does not affect the heat of the heating system in any way. Single-circuit boilers have low power and are only responsible for heating. However, a boiler can be connected to such a device and thereby solve the issue of hot water.

Specifications

Buyers should pay special attention to the fact that Baxi gas boilers, whose technical characteristics are almost identical among some models, still have fundamental differences. The differences may be:

• The type of combustion chamber (which can be open or closed).
• Type of hood (can be turbocharged or conventional).

Without exception, all boilers are equipped with a heat exchanger, circulation pump, expansion tank. The boilers have the ability to adjust the temperature of the carriers for both circuits.

The water temperature in the second circuit is heated in the range of 35-45 degrees.Information about all settings is displayed on the digital display. From the foregoing, we can conclude that Baksi gas boilers, the technical characteristics of which are most focused on comfort during use, will become reliable assistants for owners, intuitive in operation.

Analyzing the information about these boiler installations, it seems that the Baksi boiler is completely devoid of malfunctions, even potential ones. Whether this is true or not depends on each specific case of using this unit, on the conditions in which it operates, and on the timeliness of maintenance.

What is the difference between wall and floor boilers?

There is no fundamental difference in the design of wall and floor boilers

But, taking into account the difference in installation conditions, one can notice a significant difference in the design requirements.

Hanging the unit on the wall puts forward certain conditions, requirements for the bearing capacity of the wall, limits the boiler in terms of weight.

The floor sample can be made from more durable and heavier materials, high-quality and massive nodes can be installed.

Accordingly, such freedom from restrictions allows you to increase the power and productivity of the unit, increase its efficiency.

Floor-standing boilers Baxi are designed to heat a much larger area than wall-mounted installations.

They are able to heat industrial or public premises up to 500-600 m2, which wall-mounted boilers cannot.
