Source of heat and hot water in your home
The NAVIEN Deluxe NCB700 24k boiler is a wall-mounted appliance with a heat output of 23.8 kW. Thanks to the condensing principle of operation, it is efficient and economical. This unit has a good hot water capacity (with a liquid temperature difference of 30 °C, it can produce up to 13.4 liters of hot water per minute). Therefore, in addition to heating the house (up to 192 m²), the boiler can simultaneously provide a couple of points of water intake with heated water. At the same time, the heat output of the burner can be adjusted in a wide range (from 10% to 100%), changing the heat output from 4.1 kW to the maximum so as not to use "extra" gas when it is not needed.
Design features
Operation modes are controlled using the touch panel. It is also possible to separately buy a remote control or even control the boiler by phone. These tasks are solved by installing additional accessories that support the OpenTherm protocol. Regardless of the control method, the water temperature set by the user is maintained very precisely (± 0.5 °C). The burner and double heat exchanger are made of stainless steel. The use of materials that are not afraid of corrosion in the design of the most important parts ensures the reliability and long service life of the equipment as a whole.
Korean approach
In the world of heating equipment, boilers and water heaters manufactured by the Korean company Navien (read "Navien") are considered something like analogues of Hyundai Solaris and KIA Rio in the car market. They are cheaper than "Germans" or "Italians", but almost at the same technical level. So why pay more? Moreover, the boilers of this brand were initially “sharpened” for east european operating conditions. For example, NAVIEN Deluxe NCB700 24k works perfectly with reduced gas pressure in the line and, thanks to the built-in protection, is not afraid of power surges (up to 30% up and down from the nominal power supply parameters). Therefore, this boiler is optimally suited for houses in settlements with old infrastructure. In addition, it is quite easy to reconfigure to propane (for this it is better to invite a specialist), which is very important for residents of non-gasified areas who do not want to mess with solid fuel boilers that run on coal or wood.
