The BAXI Slim boiler is modern, elegant, efficient. Floor-standing gas heating boilers Baxi SLIM Baxi slim floor-standing

Floor-standing gas boilers Baxi SLIM i, iN, Fi, FiN, HP

What is the difference between boiler models with the designations i, Fi, iN, FiN?

First digit:
1 - single-circuit boiler for heating only
2 - double-circuit boiler for heating and hot water supply (hot water supply)
Further:
Letter F- closed combustion chamber with forced removal of combustion products.
Without the letter F- open combustion chamber with natural removal of combustion products.
iN, FiN- a boiler without a built-in expansion tank, circulation pump, safety valve and pressure gauge (there is a letter N). This allows the buyer to independently select and purchase the necessary equipment for a specific heating system.
i, Fi- the boiler is equipped with a built-in expansion tank, circulation pump, safety valve and pressure gauge (no letter N).
For example:
SLIM 1.230 FiN- single-circuit heating boiler, with a closed combustion chamber, without additional hydraulic accessories.

Features of Baxi SLIM floor-standing gas boilers:

SLIM 1. …i (N)- floor single-circuit open combustion chamber. Wide range of models. Power range from 15 to 62 kW. Electronic flame modulation and built-in self-diagnosis system. Modern design and minimal overall dimensions (only 35 cm wide) make it easy to place the boiler anywhere.
SLIM 1. …Fi(N)- floor single-circuit gas boilers with cast iron heat exchanger and closed combustion chamber. Equipped with a coaxial chimney.
Electronic flame modulation and built-in self-diagnosis system provide increased ease of operation and maintenance. Modern design and minimal overall dimensions (only 35 cm wide) make it easy to place the boiler anywhere. They are convenient when placing the boiler in a residential area, for example, in the kitchen, when it is not possible to organize a standard chimney.

SLIM 2. …i(Fi)- floor double-circuit gas boilers with cast iron heat exchanger and built-in boiler. Thanks to the built-in boiler, the boiler is a ready-made mini-boiler room that does not require additional accessories for organizing hot water supply. Electronic flame modulation and built-in self-diagnosis system provide increased ease of operation and maintenance

SLIM HP- floor-standing gas boilers with a cast iron heat exchanger. A series of highly efficient gas boilers with a two-stage atmospheric burner. A sectional heat exchanger made of highly plastic eutectic cast iron with profile fins has a large heat transfer surface and excellent aerodynamic properties. Thanks to the fiberglass insulation placed under the casing, heat loss is minimal.

Advantages of Baxi SLIM floor-standing gas boilers:

  • Boilers with modern design and compact dimensions. The width of single-circuit models is only 35 cm.
  • Built-in electronic self-diagnosis system, which allows you to automatically detect up to 10 types of possible malfunctions in the operation of the heating system, which makes it easy and convenient to operate and maintain the boiler.
  • The presence of built-in weather-dependent boiler automation with the ability to connect an outdoor temperature sensor allows you to automatically change the temperature of the heating system depending on the outside temperature, which provides a high level of comfort and real gas savings. To create a comfortable microclimate in the room, you can also connect a room mechanical or programmable thermostat to the SLIM boiler.
  • Availability of models with a closed combustion chamber. These types of boilers are extremely convenient when it is not possible to organize a standard chimney, as well as when placing the boiler in a living space, for example, in the kitchen.
  • Thanks to the continuous modulation of the burner flame, rather than its stepwise regulation, smooth adjustment of the boiler power is ensured, which ensures its long-lasting operation and saves gas consumption.
  • The boilers are adapted to Russian operating conditions and are resistant to changes in gas pressure, operate stably at low pressure, producing at least 50% of the thermal power at an input gas pressure of 5 mbar.
  • Automatic frost protection, which is activated when the water temperature drops to 5°C. Included in the delivery set for the SLIM boiler model with a power of 62 kW. includes a minimum gas pressure switch, which puts the boiler into standby mode and automatically turns it on when the gas supply is restored. The minimum pressure switch is very useful in winter in case of possible interruptions in gas supply and it can also be used for other models of boilers in this series.
  • The presence of two temperature control ranges (30 - 85°C and 30 - 45°C) allows the use of boilers when operating in “warm floor” mode only.
  • The heat exchanger sections are made of high quality cast iron.
  • Double-circuit boilers have a protection system against the appearance of legionella bacteria in the system, which once a week heats the water in the boiler to a temperature above 60°C, preventing their appearance and ensuring the safety of the consumer’s water supply.

Single-circuit boilers can be connected to Slim UB series boilers with a capacity of 80 or 120 liters with a tank made of enameled or stainless steel. The boiler is made in the same design as the boiler and the temperature in it is controlled either from the boiler panel or from the boiler panel.
