The 175s adopts condensation technology, multiple protections, and a fully water-cooled combustion chamber design, which is more efficient and energy-saving, with a single heating area of 3,500 square meters.


1. Small body, large energy, small footprint (1.4 square meters), small size, light weight, easy to transport and install;
2. New energy-saving heating system, independent working mode;
3. The integral cast aluminum heat exchanger is adopted, which has high heat conduction efficiency, strong corrosion resistance and low noise;
4. Mature equipment technology (parts imported from Europe, safe and reliable, stable operation, service life up to 30 years);
5. Simplified operation, humanized design, remote control, central constant temperature control, digital display microcomputer intelligent control (simple operation, no need to be on duty, low maintenance cost);
6. Ultra-low emission: NOx emission is less than 30mg/m3 (completely lower than the national emission standard);
7. Condensation technology, multiple protections, low operating costs (saving 30%-50% compared to traditional heating and central air-conditioning equipment);
8. The combustion chamber is fully water-cooled, with parallel water channels, low water flow resistance, and integrated rib column combination for heat exchange and condensation of the flue system;
9. Power 99KW, 120KW, 175KW, single heating area (400-2500 square meters);


  1. High efficiency and energy saving

The thermal efficiency of the cast aluminum condensing boiler is more than 35% higher than that of ordinary boilers, up to 108%.

  1. Low nitrogen combustion

The NOx emission per cubic meter under the standard working condition is less than 30㎎/m³, which is in line with China's increasingly stringent NOx emission standards.

  1. Low installation cost

Small size, light weight, wheel support, use PVC pipe to increase the service life of the smoke pipe, easy to install

  1. More stable operation

Intelligent control, precise temperature control, multiple safety protections, and imported high-end accessories ensure safe and reliable operation

  1. Worry-free use

The powerful intelligent control system and perfect product after-sales service system ensure that users can feel at ease during use.

  1. Longer life

Synchronized with European advanced technology and in line with European standards, core components such as cast aluminum heat exchangers are designed to have a long service life.

  1. Small footprint

Taking the 1100KW boiler model as an example, it covers an area of about 2 square meters, and the heating area can reach more than 20,000 square meters.

  1. Low maintenance cost

Low cost, long life, simple structure, high quality accessories, strong versatility, less wearing parts, easy maintenance.
