BTR (BTRO) Series Commercial Condensing Low Nitrogen Capacity Gas Water Heater

All-new condensing design, efficiency up to 105%

In traditional gas equipment, the latent heat of vaporization of the steam in the high-temperature flue gas produced by combustion is not utilized. However, with the condensing容积式 gas hot water heater, advanced condensing technology is employed to cool the flue gas to 40~80°C, thereby fully utilizing the latent heat of vaporization of the steam. Consequently, under the same input load, the heat output is increased by approximately 15%.

Performance Features

High-efficiency energy-saving

Top full premixed combustion, significantly enhancing combustion efficiency. Unique spiral heat exchanger, fully absorbing the latent heat of vaporization of water vapor in flue gas, achieving a thermal efficiency of up to 105%.

Easy installation

Two models (indoor unit, outdoor unit), compact in size; can be connected for balanced exhaust ventilation without consuming indoor air.

Safe and reliable

Electrical spark ignition, low-load start-up; featuring a four-tier protection system including temperature controller, high-temperature limit, over-temperature protection, and temperature-pressure safety valve to ensure safe operation; pressure-bearing capacity up to 1.1 MPa.

Effectively manage fluctuating pipeline water pressure.

Long service life

Optional 1: 316L stainless steel inner tank, 316L furnace tube, 304 outer shell, food-grade stainless steel quality guaranteed, offering the inner tank enhanced durability protection.

Option 2: Full-body enameling for the main unit, resistant to acidic and alkaline water, especially effective in anti-corrosion and scale prevention, extending the overall service life.

Option 3: Full-body hot-dip galvanizing treatment for the main unit. The galvanizing process is mature and stable, cost-effective, and offers high value for money.

Low-Nitrogen Eco-Friendly

Two emission options: Standard and Low Nitrogen. The Low Nitrogen model emits less than 30mg/m³ of NOx, meeting the latest environmental protection standards and being more environmentally friendly.
