Closed-Loop Hot Water Boiler

Intelligent High-Efficiency Heating for Commercial and Industrial Applications

  • Ultra-Low Emission series
  • Classic series

Technology Overview

EASE closed-loop hot water boilers are engineered for commercial hydronic heating, indirect domestic hot water generation and industrial heating applications requiring reliable temperature control, high efficiency and intelligent operation.

A closed-loop hot water boiler is a heating system that circulates treated water through a sealed hydronic loop. Unlike open heating systems, the same system water is continuously reused, helping maintain stable heat transfer performance and reducing water replacement requirements.

EASE integrates high-efficiency combustion, condensing heat recovery, intelligent control and complete system engineering to provide reliable heating solutions for hospitals, hotels, high-rise buildings, schools, commercial facilities and industrial plants.

Engineering Design

Closed-Loop Hydronic System Design

The boiler operates with a sealed circulating water system. Treated water continuously transfers heat between the boiler and heating network without direct exposure to the external environment

igh-Efficiency Condensing Heat Recovery

The boiler can incorporate condensing heat recovery technology to capture additional heat from flue gas and improve thermal utilization.

Intelligent Load Matching and Modular Operation

Multiple boilers can operate in parallel through intelligent sequencing control to match real-time heating demand.

Digital Intelligent Boiler Management

PLC and HMI systems monitor temperature, pressure, burner load, flue-gas temperature, oxygen concentration, pump operation and alarms.
