Floor‑standing condensing boiler VKK 656/4 ecoVIT exclusive 0010007526

Floor‑standing condensing boiler, 64.5 kW, designed for large facilities and retrofitting old installations

The boiler is constructed of steel and equipped with a closed combustion chamber, guaranteeing safe operation at any system pressure. Efficiency reaches 108 % at 50–30 °C – this results from the use of the latent heat of water‑vapor condensation in the exhaust gases, reducing gas consumption compared with traditional boilers.

Dimensions: 1257 mm height, 570 mm width and 691 mm depth – allows installation in existing boiler rooms, even where space is limited. The device weighs approximately 120 kg – requiring a stable floor and proper level mounting.

Power modulation from 20 % to 100 % enables matching the output power to the actual heat demand – eliminating frequent on/off cycling, which reduces fuel consumption and component wear. It can be used standalone or in cascade – up to four units – providing flexibility when designing systems for buildings with large heating areas (up to approx. 600 m²).

Designed for retrofitting old installations – no need to replace the entire pipe network. It operates efficiently even at lower supply temperatures, making it compatible with low‑temperature radiators or floor heating.

Electronic ignition provides safe and rapid start‑up. No manual reset is required after short power interruptions – the unit automatically resumes operation once voltage is restored.
