Safe:
- Utilize the safest balances forced air-supply and exhaust means,
ensure the complete insulation of the
combustion air and exhaust gas from the living rooms,and negative
pressure combustion prevents exhaust
gas from polluting the indoor air under any circumstance.
- Twenty sufficient safety protections for guarantee.
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.
