At Gastek, we engineer intelligent hot water and heating systems tailored to global environments and user demands. With **13+ years of ISO 9001-certified expertise**, our CE/ERP-compliant products deliver unmatched adaptability for residential applications.
Our **instant tankless gas water heaters** are engineered for real-world challenges:
✅ **Environment-Adaptive**: Optimized for unstable power supply or 110V/220V different power supply voltage, low water pressure (0.01-1.0 MPa), high altitude (up to 3,000m), and gas types (natural gas/LPG).
✅ **Demand-Driven Configuration**: Customize outputs (5-24L/min) based on simultaneous usage points (showers, sinks, etc.) and venting constraints.
✅ **Comfort pursuit**: Big hot water outputs up to 24L/min and constant temperature stability achieved.
Introducing the **Full Premixed Condensing Boiler** – redefining energy intelligence:
✅**108% Thermal Efficiency** – **20% gas savings** vs. conventional models.
✅**Extreme Environment Ready**: Stable combustion under sandstorms and high altitudes.
✅**4kW Low-Load Mode**: Silent summer operation with precise 35-60°C output, eliminating overheating waste.
*Ideal for luxury villas & eco-conscious hotels.*
Our **corrosion-resistant electric boilers** innovate safety and flexibility:
🔌 **Water-Electricity Separation**: this technology eliminates leakage risks.
♨️ **98% Efficiency**: Pair with buffer tanks or solar systems for hybrid radiant floor heating.
🌍 **Multi-Scheme Compatibility**: Supports underfloor loops, fan coils, or domestic hot water storage.
Powered by a resilient, globally-integrated supply chain network to ensure seamless operations.
Rigorous end-to-end quality control systems certified to ISO9001 standard, from raw materials to final delivery.

At GASTEK, we engineer more than products - we build enduring partnerships. Through operational transparency and shared value creation, we empower global clients to achieve sustainable competitive advantages in dynamic markets.
Gas and air are mixed fully before combustion so that the overplus air coefficient is between 1.1-1.3. Boilers can fully combust with low oxygen content accordingly. Moreover, by using the technology of catalyzed combustion, it is efficient to avoid many emissions such as CO and NOx. CO content in exhausted fumes is below 60ppm and NOx is below 40ppm. The emission of Co is much less which is only 1/10 of the national standard. And emission of NOx reaches level 5 of the European standard which is less than 50 ppm.
