High‑output condensing boiler VKK 1606/3‑E 0010016462

High‑power standing condensing boiler for multi‑family and tertiary buildings

The VKK 1606/3‑E boiler is a single‑function gas appliance, designed to supply heating systems in buildings with high heat demand — from multi‑family houses to service buildings. Its rated power is 164 kW at a temperature difference of 50–30 °C, which allows efficient coverage of heating needs even in larger facilities without the need for multiple units.

Efficiency reaches 108 % at low return temperature (condensing), and under standard operating conditions — 100 %. This means that in low‑temperature systems (e.g., floor or wall heating) the unit operates at maximum efficiency, reducing gas consumption and operating costs. It does not require special flue channels — it is compatible with conventional chimneys, but requires condensate drainage.

Dimensions (695 × 1285 × 1240 mm) make the boiler compact for its power — it occupies no more space than smaller models, and its floor‑standing design simplifies installation in existing boiler rooms. It is a solution for installers who need power without space compromises.

Compared to lower‑power models (e.g., VKK 1206/3 or VKK 2006/3), this model offers an optimal balance between performance and size. It does not need to be connected in parallel with other boilers — a single unit suffices, reducing failure points and simplifying service.

It does not have domestic hot water preparation — it is intended solely for heating. Therefore it fits perfectly with systems that have a separate boiler or buffer tank.
