Let's try to look at the Baxi Slim model from different angles in order to get closer to answering the question of what makes buyers around the world prefer these particular boilers.
Floor boilers: advantages and disadvantages
Baxi Slim boilers are high-performance floor-standing units that operate on natural gas. A feature of this technique is that it is equipped with a cast-iron heat exchanger, which has a rather long service life, which is confirmed by practice. Experts in the home appliance market note that the cast-iron construction used in the Baxi Slim series is ideally suited for constant use at the limit of possibilities. Given the peculiarity of the conditions in which the boiler is to operate in the northern regions of our country, this plus is obvious.
Boilers floor Baxi Slim will please with the vastness of the model range. The line includes units in various modifications, which differ from each other in terms of rated power. This parameter, depending on the model, ranges from 15-62 kW. The most powerful units are designed for heating not only large residential premises, but also administrative facilities.
Electronic flame modulation is one of the important innovations that is used in the design of the Baxi Slim boiler. The presence of a fault self-diagnosis system indicates the company's desire to make working with equipment as user-friendly as possible, allowing the equipment to solve the main problems without human intervention. The presence of a system for self-detection of errors also greatly facilitates the maintenance of boilers. It is enough, using the instructions for Baxi Slim, to decipher the error code in order to understand what kind of malfunction was detected during operation.
Minimalistic design and small dimensions are one of the main distinguishing features of this series of boilers. By the way, they got their name precisely because of their compactness. The width of the unit is only 35 centimeters, which makes it possible to find a place for the boiler even in the plumbing unit, whose area is 3 square meters.
Technical features of the Slim model
Speaking about the performance of Baxi Slim boilers, you should first of all pay attention to the gas system of these units. It has a number of distinctive features that make the technique of the Italian brand special. Among them:
- Constant electronic flame modulation. This function is active in both operating modes of the boiler.
- Smooth ignition of the burner. This property implies a careful attitude to all components, which prolongs the life of the heating equipment as a whole.
- Burner made of high quality stainless steel. The technique of this model can be used under any conditions, including high humidity. The design of the built-in burner is adapted for operation in Russia, including regions that are unfavorable in terms of climate.
- The equipment functions even when the fuel inlet pressure drops to 5 mbar. It is known that in many regions of our country the problem of pressure instability in the gas supply system is relevant. Fortunately, this problem is not terrible for Baxi Slim boilers, which continue to work no matter what.
- A universal design that allows you to connect the system to liquefied gas cylinders when changing nozzles. In this regard, technology is indispensable for the inhabitants of non-gasified areas of our country.
The hydraulic system of Baxi Slim boilers also has its own characteristics. Among them:
- Cast iron heat exchanger, which was discussed above.
- The circulation pump equipped with the automated air removal. Exceptions are modifications of the iN boiler. They do not have this option.
- Boiler (provided only in double-circuit units).
- Boiler pump.
- Pressure gauge.
- Pump post-circulation system.
- Possibility of aggregation with an external storage boiler offered by an Italian company.
Baxi Slim boilers boast of their temperature control systems. Firstly, the equipment can operate in standard mode (temperature range is 30-85 degrees Celsius) and in "warm floor" mode (temperature range is 30-45 degrees Celsius).
Secondly, the units are equipped with a remote control. As an additional option, together with the boiler, you can order a climate controller, which is not included in the standard set of heating equipment.
Thirdly, the design provides for the presence of weather-dependent automation. If you want to completely entrust all the worries about your comfort to the equipment, it is possible to connect the so-called outdoor temperature sensor. The device will choose the optimal mode of operation for itself.
In addition, the unit is able to maintain the temperature of the coolant in the circuit at a certain level. Naturally, almost any technique is able to do this, but the existence of such an alternative to weather-dependent control was worth mentioning.
The Baxi Slim series boiler can be aggregated with a programmable timer. Such a device makes it possible to adjust the operation of heating equipment exactly according to the schedule that is preferable for you. This feature is useful if you often leave home. A programmable timer in this case will pay off pretty quickly due to fuel savings. Separately, it should be said that the boilers of this model have an electronic temperature indication, which is very convenient.
Italian engineers took care not only of savings and high performance, but also of the safety of equipment. An electronic system for self-diagnosis of faults, a thermostat that prevents overheating of the coolant in the system, a draft sensor, pump blocking protection, a safety valve in the heating circuit and the DHW circuit, as well as an antifreeze system are the most important safety elements available to every owner of Baxi Slim.
