Indirectly heated stationary water heaters of the NTR and NTRR series They are used to produce DHW through another source of heating water, most often a gas boiler. The NTRR types combine two sources of heating water (gas boiler + solar system, heat pump). With their nominal performance, they provide a sufficient amount of DHW for large residential buildings, plant departments, restaurants and similar facilities. In case of increased consumption of DHW, the water is continuously heated and works similarly to flow-through water heaters.
2. Advantages of using an indirect heating water heater.
- Easy installation and connection to heating water.
- Very fast heating of DHW.
- The enameled steel tank meets the quality of DHW in all hygienic requirements.
- The built-in magnesium anode increases resistance to corrosion.
- High-quality polyurethane insulation ensures minimal heat losses.
- Connection of a large number of reception points.
- In the two heat exchanger types, the surface of the heat exchanger
can be doubled by using two heating water sources or by connecting them.
- Accurate control of the DHW temperature.
- The possibility of connecting the DHW circulation.
