Selection of the right water heater is important so that you get reliable and safe performance for years. Compromising on certain aspects can prevent you from enjoying hot water when needed. Following aspects are important at the time of choosing a water heater:
Both have their plus points. Storage water heater will give hot water at the set temperature upto 75ðC and store it for later use too. Instant water heater will give hot water in minutes with no waiting time. However, Instant water heater will not give piping hot water in cold climate areas. It is more suited for moderate climate areas.
Choose the water heater according to your application and the number of persons using the same. The climatic condition of your city will also influence the capacity of the water heater
Hard water will cause scale deposits on the tank and heating element corroding them and result in premature failure. Increased energy consumption will also be there.
Glass lined tanks and copper tanks can withstand hard water without failure for years. Water heater with glass lined or copper tanks will last longer in hard water. Incoloy elements will last longer than ordinary element in hard water. Glass lining on tank and heating element will reduce scale deposits and avoid premature failure.
There are a number of safety features to prevent excessive temperature or pressure inside the water heater Thermostat, Thermal cutout and Multi Function Valve. These are as per IS standard.
Energy consumption in water heaters is surprisingly much lower than other household appliances mainly because water heater work for a very short time as compared to other appliances (Air conditioner, Refrigerator, TV etc.) Our models have star rating by Bureau of Energy Efficiency. Most of the models are either 4 or 5 star rated the highest energy efficiency rating.
MFV refers to Multi Function Valve.During heating the water inside the water heater will expand due to thermal expansion. The expansion of the water is allowed by the return of water back through the inlet line to the overhead tank. The Multifunction valve provided with the water heater has an inbuilt mechanism to allow thermal expansion of the water inside the tank during heating. In this manner the pressure inside the tank remains constant without increasing during each heating cycle.Note: For thermal expansion to take place it is important that there be no prevention of back flow of waterthrough the inlet line.Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.
When the water heater is connected to a pressure pump there are some important things to be noted. If the pressure from the pressure pump is beyond the rated pressure of the water heater (8 bars/kg/cm2), then the MFV water will be released continuously from the MFV even in cold condition. In this case, reduce the pressure setting of the pressure pump to a lower level. Further, during the heating phase, the water inside the storage tank will expand and try to go back through the Inlet line due to thermal expansion. But the Pressure pump on the inlet line will not allow the water to expand. So the water pressure inside the tank will increase and in such condition the MFV will start dripping to release the pressure and protect the tank from damage. This dripping is slow and intermittent and will stop as soon as the heating stops (when the heater switches off). The dripping will restart once the heating starts again. This is quite normal as the MFV is working properly to release the excess pressure insider the tank. In this case, please provide a PVC tube from the MFV to the nearest drain point. This will allow the expanded water to drain without affecting any internal fittings.Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.
In high rise buildings (20 floors or more) supplied from an overhead tank on the rooftop, there can be incidence of very high water pressure at the lower level floors. To protect the taps and fittings from damage due to high pressure, there may be a Pressure Reducing Valve fitted on the cold water line to the water heater. When the water heater is connected to a pressure reducing valve on the inlet line, there are some important things to be noted.During the heating phase, the water inside the storage tank will expand and try to go back through the Inlet line due to thermal expansion. But the Pressure reducing valve on the inlet line will not allow the water to expand. The water pressure inside the tank will increase and in such condition the MFV will start dripping to release the pressure and protect the tank from damage. This dripping is slow and intermittent and will stop as soon as the heating stops (when the heater switches off). The dripping will restart once the heating starts again. This is quite normal as the MFV is working properly to release the excess pressure inside the tank.In this case, first check whether the pressure reducing valve can be removed; if the line pressure does not
exceed 6-7 bars/kg/cm2 it may be removed without affecting the water heater. If it is not possible to remove the pressure reducing valve due to technical reasons, then provide a PVC tube from the MFV to the nearest drain point. This will allow the expanded water to drain without affecting any internal fittings. Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.

Porcelain enamel is a glass line coating given to the inner tank. The glass lined tank is then protected from corrosion in contact with water and can last for years. The glass lining also reduces scale deposits in hard water.
Warranty varies from model to model. The inner tank carry warranty from 5-10 years. The heating element has a warranty from 2-3 years. Overall product has a warranty of 2 years.
