Gas-fired Hot Water Boilers for Heating and Space Heating, Large Commercial Storage Gas Water Heaters for Hotel, School and Prison Projects
Free Energy Gas Volumetric Water Heater | Overseas Promotion Version
Official Overseas Version (Concise & Technical)
Free Energy gas-fired volumetric water heater integrates three core patented technologies for efficient, durable and low-maintenance commercial hot water supply. Equipped with a patented Venturi adiabatic expansion heat tube, it delivers enhanced heat exchange, low wind resistance and anti-dust performance, maintaining consistent high-efficiency operation long-term.
It adopts an innovative graphene nano-ceramic cold enamel inner tank, featuring excellent anti-scaling, acid and alkali resistance, and anti-aging properties. It avoids cracking and peeling issues of traditional enamel, greatly extending the equipment service life.
The precision full-premix combustion system ensures optimal gas-air mixing and full combustion, achieving an ultra-high thermal efficiency of 108% with low NOx emissions. Energy-saving, eco-friendly and highly stable, it is ideal for hotels, schools, factories and various commercial hot water scenarios.
