Condensing Hot Water Boiler

Condensing Hot Water Boiler

Description

Compared with common boiler, condensing boiler adds condensing waste heat recovery unit, which unit is used to absorb the thermal heat from flue gas with high temperature and then reach function increased 6%~15% heating efficiency.

Outstanding condensing technology features

  1. High efficiency making full use of the flue gas through waste heat recovery unit ensures higher thermal efficiency.
  2. Save cost: although condensing unit itself costs much, while from long time view, it saves great fuel consumption for client
  3. Environment friendly: during the condensation process of the water vapor in flue gas, the water absorbs much harmful gas (NOX, SOx, etc., ) and then the gas discharged into air is lower national discharge standard.
  4. Low noise: the fin structure deduces flue gas emission noise.

Safety features

  1. Flue gas alarm: once the flue gas exceeds setting value, it will alarms
  2. Power failure protection.
  3. Time setting function.
  4. Power cuts self-locking protection function.
  5. Automatically check water level lower limit and alarm function.
  6. Over-pressure interlock protection.
