Very pleased with the gas consumption – compared to my old boiler just a fairy tale, build quality is more than good, normal price, works very quietly.

An excellent boiler. The flexibility of venting and pipework makes this boiler a great option for retrofitting. A great option for the money.

The efficiency of the boiler is quite acceptable and it provides a stable heat supply to the house. However, I did not notice significant savings in gas consumption as promised. Overall, the TFT340 boiler performs as promised, but given its unpredictable performance, I would recommend doing more research before purchasing to ensure it meets your requirements.

The boiler is good, with good noise insulation. We used this boiler for more than 5 years, so we chose this model and manufacturer for our parents. Never once let us down, we continue to use it. Completely satisfied.

Great boiler, looks stylish, easy to understand menu!
Advanced user interface with Setup Wizard is made easy with backlit panel, click-wheel control and intuitive text.
Low gas pressure operation. Negative pressure regulating gas valveensures maximum performance all the way down to 3.5″ of water column on natural gas and 8″ of water column on propane gas.
Dual Venturi system creates better combustion control, turndown ratio and easy field gas conversions.
1/2″ gas pipe capability up to 24′ (subject to local codes). Cuts installation time, no need to install new gas lines for retrofit applications.
Patented stainless steel fire tube heat exchanger Navien’s innovative heat exchanger design is ASME‑Certified,“H” Stamped, and reduces high-stress point weld failures common on other combi-boilers.
