Electric Vacuum Hot Water Boiler
Rated Hot‑water:
0.35 - 2.8 MW
Rated Heat:
30-240 × 10⁴ kcal/h
Thermal Efficiency:
98 - 99%
Design Pressure:
-0.02 MPa
Application Industries:
Widely used for central heating and sanitary hot‑water supply in hotels, hospitals, schools and commercial buildings.
Technological Advantages:
Noise‑free zero‑nitrogen‑oxide emission, easy installation, vacuum anti‑corrosion structure, premium Incoloy 800 heating tubes, multi‑safety protection and fault‑alarm intelligent control.
Product Introduction
The interior of an electric vacuum hot water boiler is a hermetically sealed integralstructure. During operation, oxygen in the intermediate medium water precipitates andis discharged outside the electric vacuum hot water boiler, so oxygen corrosion will notoccur inside the vacuum hot water boiler for a long time.
Core Advantages
Eco‑friendly: Noise‑free, zero nitrogen‑oxide pollution, easy installation.

Long Lifespan: Vacuum inner chamber avoids oxygen corrosion.

Full Safety Protection: Leakage, water‑shortage, grounding, overpressure, overcurrent & power supply protection.

Premium Heating Tube: Incoloy 800 nickel‑alloy tube with German reliable quality.

Intelligent Control: Fault alarm & auto protection for safe boiler operation.
