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.
