They would also like to find out whether Rubine water heaters are reliable, and we have discussed the features below.


Rubine Sphere Series

The Sphere series of the Rubine storage water heaters consist of compact water heaters of a capacity of 15 liters and 30 liters. One of the reasons why this series is very reliable is due to the use of an SS 316 steel heating element. Which will ensure high temperatures, water, and pressure without getting rusted for a very long time. The blue diamond enamel tank is coated with enamel for great durability. Both Rubine SP 15 storage water heater and Rubine SP 30 storage water heater have a polyurethane foam, which will prevent heat loss from the hot water stored in the tank. This guarantees that the water remains hot for a longer period. The power rating of all the heaters in the series is two kilowatts.

The whirl flow technology helps the water in the heater get heated quickly. This water heater has multiple protection for water heater safety, and just like the pressure relief valve which will open when the pressure in the water heater is above the safety limit. The dry heat and overheat protection will cut off the power supply to stop the heating when it surpasses the preset temperature. To minimize corrosion in the water tank, each heater has a magnesium anode, which will react with the dissolved minerals in the water, thus they do not react with the tank body. A five-year warranty is provided for the heating element and the water tank specifies that Rubine is positive on the quality of these parts. A one-year warranty is provided for the other components. If the Rubine storage water heater has issues during the warranty, the water heater should be replaced. Supplies for Rubine water heater installation are also provided.
