The user last input: "Kocioł kondensacyjny dużej mocy VKK 2006/3-E". Need to translate to English, preserving model numbers, technical terms. "Kocioł kondensacyjny dużej mocy" = "high-power condensing boiler". Possibly "large capacity condensing boiler". Should we include "VKK 2006/3-E" as model. So translation: "High‑capacity condensing boiler VKK 2006/3‑E". Or "Large‑power condensing boiler VKK 2006/3‑E". Use "high‑power". Keep formatting? No special formatting. Just plain text.

High‑capacity condensing boiler designed for high‑demand heating installations

This unit is not a conventional boiler — it is a solution for multi‑family buildings, industrial halls or commercial complexes where constant, efficient and reliable heat delivery is critical. Its dimensions are 695 mm (width) × 1285 mm (height) × 1550 mm (depth) and it weighs 340 kg — meaning installation requires adequate space, a stable floor and planning at the design stage.

Rated power is 206 kW at a temperature difference of 50–30 °C — this value is confirmed in the manufacturer’s technical data. It is not a rounded “200 kW” figure sometimes quoted elsewhere — the figure is exact and results from the test conditions defined by the manufacturer. Efficiency is 108 % at 50–30 °C and 100 % at 80–60 °C, reflecting effective use of the latent heat of water‑vapor condensation in the exhaust gases. In practice this means lower gas consumption for the same output power — and for large facilities the operating‑cost difference becomes significant.

Powered by natural gas (GZ 50 / GZ 41.5), it operates on a condensing principle — reducing NOx and CO₂ emissions compared with traditional boilers. The standing‑frame construction, with flue pipe and condensate drain, requires standard installation practice: appropriate drainage, a flue of suitable diameter and gas supply. There is no “modern design” or “aesthetic installation” — this is a technical device that operates safely and efficiently for many years.

Installation is not simple — but you do not have to worry about frequent service. The design, based on proven components from the ecoCRAFT exclusiv line, is intended for continuous operation in low‑temperature supply systems — ideal for modern underfloor heating or low‑temperature radiators.

This is not a boiler for a single‑family house. It is a solution for the installer who knows that the goal is not the smallest unit, but the most efficient one for the given project.
