Joannes Optimus 28 kW Wood Boiler | 3-Pass Design | Non-Electronic
Description
πͺ΅ Joannes Optimus 28: Classic 3-Pass Wood Boiler for Maximum Heat Recovery
Discover the raw power and mechanical simplicity of the Joannes Optimus 28. This 28 kW wood-burning boiler is defined by solid engineering, designed specifically for users seeking a traditional heating solution without complex electronic components. Its standout technical feature is the advanced 3-pass flue gas system, ensuring superior thermal efficiency through natural heat exchange. π π₯
Built from high-grade structural steel, the Joannes Optimus 28 is the ideal choice for medium to large homes, offering total energy independence and an outstanding operational lifespan.
β¨ Technical Advantages of the Joannes Optimus 28
1. High-Efficiency 3-Pass Flue Design ππ¨
Unlike basic boilers, the Optimus 28 forces hot exhaust gases through three complete internal circuits before they exit through the chimney. This configuration maximizes the surface contact area and heat transfer time, ensuring that the energy from the wood stays in your radiators rather than escaping into the atmosphere.
2. Absolute Simplicity: Zero Electronic Controls π§π«
This model is designed to operate purely through mechanical principles. The absence of electronic circuit boards, sensitive sensors, or electric fans eliminates the risk of costly electrical failures. This makes the boiler perfect for areas with unstable power grids or for remote locations using gravity-fed systems.
3. Large Firebox for Substantial Logs πͺ΅βοΈ
The generous combustion chamber volume allows for loading large wood logs, providing extended burn times between refills. The wide access door simplifies both the loading process and the removal of ash residues.
4. Heavy-Duty Steel Construction ποΈπ‘οΈ
The boiler body is robotically welded and high-pressure tested. It is engineered to withstand the intense thermal stresses of wood combustion over decades of residential use.
