Optima HG

5th grade: 19, 25, 32 kW
Energy efficiency class: A+
Fuel: firewood - humidity ≤ 20%
Optional equipment - for an additional fee: OPTIMA HG controller, leveling feet, mechanical exchanger cleaning system, boiler maintenance tools

3-year warranty for the tightness of the heat exchanger, 2 years for other components and efficient operation of the boiler.

Heat exchanger made of certified high-quality boiler steel;

High thermal efficiency above 92% thanks to increased heat recovery from exhaust gases;

OPTIMA HG controller with support for a buffer, 3 pumps, a mixing valve and an exhaust fan;

The boiler is designed for installation in a closed system;

Two-stage combustion technique - fuel gasification and pyrolysis

Ceramic catalysts stabilizing the combustion process;

Exhaust fan eliminating the problem of chimney draft and stabilizing the operation of the boiler;

Mechanical heat exchanger cleaning system;

The HG boiler uses a two-stage combustion technique – gasification of the fuel and subsequent pyrolysis, i.e. combustion of the resulting gases. The basic fuel is firewood. The boiler exchanger is made of high-quality, certified boiler sheet metal with a thickness of 6-8 mm in the form of two chambers placed above each other – the upper one, which serves as a fuel tank, and the lower one – combining the functions of the combustion chamber and ash pan. There is a grate between the chambers, which allows for perfect gasification of wood and easy removal of ash. The wood gasification process allows full use of the energy stored in the fuel and meets restrictive emission parameters. The combustion process is regulated by an innovative controller with a touch display. The HG boiler has a built-in exhaust fan that prevents smoke from returning to the boiler room. The boiler can be installed in a closed system.

1 The maximum area of ​​heated rooms was estimated for the specific heat demand q = 70 W/m2. 2Fuel tank capacity for bulk density of eco-pea coal of 0.8 kg/dm3.


3 The weight of the boiler depends on its additional equipment.


The height of the boiler can be additionally adjusted using the included feet.


The feet have an adjustment range from 38 to 50 mm.


ATTENTION! When ordering the KOMFORT EKO LUX boiler, please specify which side the tank should be on (left or right).
