Description
The SEMAX BASIC DUO boiler is designed with small boiler rooms in mind. This device is considered a wood gasification boiler. An additional advantage of the boiler is its loading tank, which can be placed on either side, making it easier to fit into small boiler rooms. While the SEMAX BASIC DUO qualifies as a wood gasification boiler, it also allows for pellet combustion in automatic mode. The boiler is designed for efficient combustion of firewood in compliance with the 303-5:2021-09 standard, as well as wood pellets conforming to the PN EN 303-5:2021-09 standard. It is equipped with a self-cleaning burner. The pellet igniter, integrated with an RTC clock, ignites and extinguishes the boiler according to a schedule, reducing the amount of manual maintenance to almost zero. By adding the ecoNET300 internet module to the boiler, you can manage its functions using a phone, tablet, or computer.
The boiler qualifies for the "Clean Air" program.
Heat Exchanger
Type of exchanger: Horizontal, shelf, and tubular convection channels
An efficient design adapted for quick cleaning of the exchanger from the front. The construction of the boiler's exchanger ensures high heat transfer from the combustion chamber.
Chimney Outlet
Location: At the rear of the boiler
Adjustment: Top, side with fan
The boiler's design places the chimney outlet at the rear, allowing direct connection to the chimney.
Flue Gas Temperature Sensor
Along with the controller, the sensor monitors the flue gas temperature.
Primary and Secondary Air Intake
Air is drawn in through six openings for complete fuel combustion. The amounts of primary and secondary air can be adjusted using sliders.
Note: Air intakes must be fully closed when using the boiler with a feeder.
Smoke Damper
Enables efficient smoke evacuation from the combustion chamber according to user needs.
Note: The smoke damper must be fully closed when using the boiler with a feeder.
Exhaust Fan
Adjustment: Adjustable height
The exhaust fan effectively supports the natural flue gas draft in the boiler. Air is regulated using the exhaust and blower fans when operating the boiler with a feeder.
Automatic Feeder
The PLATINUM PELLET controller, based on information from sensors, determines the fuel demand and doses the required amount. This makes the fuel combustion process highly efficient, eco-friendly, and nearly maintenance-free for the user.
Boiler Control
The PLATINUM PELLET controller is programmed to automate all heating processes for your home. The user sets the desired indoor temperature, and the controller optimizes combustion accordingly. In advanced settings, you can customize every parameter according to your preferences and household needs.
Main Features:
- One heating circuit C.O.1 with a room thermostat
- Pumps (DHW, heating, additional)
- RTC clock with weekly scheduler
- Weather-based control
- Winter/summer mode
- FuzzyLogic & PID
Additional Equipment:
- ecoNET 300 Internet Module: Monitor and control the boiler’s operation, track statistics, and compare data with the internet-connected module. Access boiler control from your phone, tablet, or computer. The module also logs and records your home heating performance. With the ecoNET (wired or Wi-Fi) internet module, you can manage expenses and avoid surprises!
- Lambda Probe
- PLATINUM TOUCH Room Thermostat (wired, touch-controlled)
- PLATINUM TOUCH x40 Room Thermostat (analog, wireless)
- PLATINUM TOUCH x80 Room Thermostat (touch-controlled, wireless)
- Platinum B&C Module: An expansion module that can operate as Module B or C.
- Mode B: Adds functionality for two additional heating circuits, 2x pumps, 2x mixers, 2x universal thermostats, and H output.
- Mode C: Adds functionality for two additional heating circuits, 2x pumps, 2x mixers, and 2x universal thermostats.
Main Functions:
- Fuel: Pellet
Pellet, an eco-friendly fuel made from compressed wood waste such as sawdust or wood chips, is a fully natural energy source that turns into biodegradable ash after combustion. - Ceramic Pellet Igniter
Forget about manual ignition. One click is all it takes for the automatic ceramic igniter to ignite the fuel in the burner. Combined with the RTC clock, the automatic igniter lets you schedule the boiler’s weekly operation for summer and winter modes. - Automatic Cleaning
The burner self-cleans regularly, minimizing the need for manual cleaning. This technology prevents ash clogging in the combustion chamber and ensures excellent burner performance.
