Product Description

High Efficient Safe Gas Condensing Boiler Gas Saving Dual Temperature Sensors Control​
 
 

 
 

Advantages

Safety

(1). Gas leakage control and overheating

(2). Self-diagnosing malfunctions

(3). Flame failure safety device

(4). Anti-dry combustion protection device

(5). Over water pressure protection device

(6). Anti-wind flow-back /Anti-freezing device

(7). Auto-adjusting water temperature

(8)  Fully automatic constant temperature technology

 
 
Comfortable:
 
- Intelligent constant temperature technology built-in to maintain constant temperature water flow.
 
- Start up with super low water pressure
 
- Dual temperature sensors control.
 
- High flow hot water central supply system,able to provide multiple users with hot water simultaneously
 
- Automatically control for free adjustment of heating temperature, complying with different heating mode to
satisfy specific requirements.
 
 
 Eco-friendly:
 
- Unique inverted& flame combustion technology, low CO and Nox emissions.
 
- Advanced combustion and heat-exchanging design,low noise in operation.
 
 
 
 
European noble type appearance design with know which can be a 360 degree spin, simplicity and fashion.
 
New lid design, commissioning and maintenance is very convenient.
 
Digital display the system pressure, it would be more precisely.
