The Nasgas DEG-55 Super DLX (Double Safety) is a high-capacity water heater (geyser) designed to serve larger households or commercial settings. With a 55-gallon capacity, it ensures ample hot water supply for multiple bathrooms or heavy usage. This model is dual-fuel: it supports both electric heating and gas heating, giving flexibility in energy use and operational reliability. 

Tank durability is a priority: the inner tank is dip-galvanized using heavy-gauge steel, offering resistance against corrosion. The exterior is pre-painted with UV-resistant paint, guarding against weather and sunlight deterioration. Insulation is made using Prime Kimmco material with ~12 kg/m³ density, which helps reduce heat loss and improves efficiency. 

Safety features are emphasized: the model includes a QC-approved brass safety valve and is marketed as “Double Safety” to highlight redundant protective measures.  The burner is grey iron cast, thermally efficient, helping ensure stable heating when in gas mode. 

Overall, it is a robust, versatile water heating solution for users who want both capacity and safety.
