Gas boilers Naviens are distinguished by their compact dimensions and also meet all European quality standards and safety and comfort requirements that such equipment must meet. Gas boilers are made from high-quality materials and are distinguished by their quality, efficiency and reliability. Read the connection instructions gas boiler Vaillant.
The most important advantage of Navien gas heating equipment is its adaptability to the difficult conditions of the Russian climate, to the low level of incoming pressure of liquid coolant and gas, as well as to constant voltage surges in the electrical network.
Initially, Navien boilers are configured to work with natural gas, but it is possible to convert some boiler models to liquefied gas. To do this, you will need to purchase a manifold with injectors.
Navien gas boilers can operate even on low-quality fuel. They do not notice voltage drops, even if the surges reach a level of 30%.
A failure of a gas heating device can only occur if the pressure level in the heating system decreases, but this fact also becomes a “+”, because if the coolant liquid leaks, the boiler will stop working, which will protect the entire system from more serious problems.
All heating gas boilers are covered with anti-corrosion material.
Also, the cost of Navien gas boilers makes it accessible to almost the entire population of the country.
On the Russian market of heating devices, the Navien company provides the following types of products:
Commissioning and initial setup of Navien heating equipment is carried out by specialists technical service support. Often the seller company offers installation and commissioning of equipment along with delivery. You shouldn't give up on this, because self installation and initial launch may void the consumer's warranty. You can read about this in the instructions that come with the boiler.
In accordance with the complete set of heating equipment from the Navien company, along with the gas boiler, the consumer receives a warranty card, fasteners for installing the gas boiler, the heating unit itself and the operating instructions.
