FAQ
1. Does this unit require preheating?
No! This is an instantaneous model that delivers hot water in just 3 seconds - no waiting time.
2. Can it work with low water pressure?
Minimum operating pressure is 0.02MPa (~20kPa). For high-rise buildings or unstable pressure, we recommend installing a booster pump (available as an accessory).
3. Will it provide enough hot water in winter?
Maintains 60℃ output even at -15℃ ambient temperature (requires ≥5℃ inlet water). For extreme cold regions, add the Anti-Freeze Kit (with electric auxiliary heating).
4. Does installation require gas line modification?
Must be performed by certified gas technicians. We provide free onsite design service (standard installation parts included, special materials charged separately).
5. How to switch between natural gas/LPG?
⚠️ Professional service required to replace burner nozzles and adjust valves (DIY attempts may cause gas leaks!). Specify fuel type when ordering.
