It is important to select the best water heater for your home, especially one that performs reliably and safely for many years to come. Please keep the following aspects in mind when choosing one:
a) Electrical Storage Water Heater - A storage water heater will deliver hot water at a specified, pre-set temperature up to 75°C. It has a tank that stores water. When switched on, the water is heated to the set temperature, and can be used later for bathing.
b) Electrical Instant Water Heater - An instant water heater heats water as it flows through the device. A low waiting time is one of its main advantages. However, it will not deliver adequate hot water in areas with a cold climate. It works well in areas with a moderate climate, such as Mumbai and Chennai.
You must choose the capacity of your water heater to best suit your application and type of usage. The climatic condition of your city should also be factored into your choice. The chart below will help you to decide the right capacity to buy.
|Capacity (In lts)
|Inlet water temp. >20 C
|Inlet water temp. <20 C
|1 L or 3 L Instant
|6 L or 10 L
|15 L or Above
|25 L or Above
|50 L or Above
|70 L or Above
|100 L or Above
Hard water will cause scale deposits on the heating element of your electric water heater. This will reduce its heating efficiency. Over a period of time, the scaling will result in corrosion and lead to premature failure of the element. Ferroli water heaters are equipped with the patented Blue Forever heating element, designed to reduce calcareous deposits and scaling, which increases the life of the heating element significantly. This also increases heating efficiency.
Water heaters with the conventional copper heating element require regular descaling or replacement due to the deposition of calcium on the element, over a period of time. The Ferroli Blue Forever heating element is coated with silicon enamel. The enamel completely isolates water from the metal. This prevents deposition of calcium, thereby improving the durability of the element. The sacrificial aluminium anode provides additional protection of the element and the tank. This anode forms a thin oxide film on the element and the tank, which offers resistance to any further corrosion. The anode will gradually get consumed due to the ionisation process. It will require a replacement only when completely corroded.
The inner tanks of electrical water heaters are made with different materials such as copper and stainless steel. A copper tank is not suitable for high rise buildings due to its low pressure withstanding capacity. Stainless steel is susceptible to corrosion in hard water conditions. The Ferroli water heater tanks undergo a special, corrosion-proof treatment called the Blue Silicon enamel powder coating process. This treatment uses a hi-tech, electro-static application technique. The subsequent baking in the furnace at 870° C creates a perfect glass lining on the tank, ensuring a longer life. It also creates an ultra-hygienic surface inside the tank, thereby retaining purity of the water, sustaining high pressure and suitability in hard water conditions.
The pressure withstanding capacity of the water heater depends on the tensile strength of the inner tank. The thicker its material, the more its tensile strength. Ferroli?s Blue Silicon enamel tank is thicker and thus has a much higher capacity to withstand pressure. It is suitable for high rise buildings and pressure pump applications. Its outstanding pressure resistance performance extends the life of the tank and enhances its safety.
Most water heaters do not have any temperature indication. The user has to touch the hot water to sense its temperature. This may result in discomfort and burns at higher temperatures. Ferroli water heaters are equipped with a digital display which shows the temperature of the hot water inside the tank. The regulating knob allows the user to set the desired water temperature, from the ambient temperature to a maximum of 75 degrees Centigrade. The heater is provided with LEDs to indicate the heating and cut off modes.
The following components ensure a high level of safety during the operation of the water heater:
Water heaters remain switched on for very short durations compared to other appliances such as air conditioners, refrigerators and TVs. Thus, their energy consumption is lower than that of other household appliances. You can check the energy saving label on the product for its BEE star rating. Ferroli water heaters have high quality, injected PUF insulation that is far superior to that of other heaters. This helps conserve heat longer, ensuring high savings on energy. Most Ferroli water heaters are certified by the Bureau of Energy Efficiency and have the highest rating i.e. the BEE 5 star rating.
Ferroli has a network of authorised service centres to provide general service or in the unlikely event of a breakdown. Customers can contact us on ourtoll free customer care number 1800-103-8533 or register a service call by visiting our website www.ferroli.co.in.
In addition, Ferroli has the set up several communication channels for the convenience of customers.
The warranty varies with the brand. Ferroli Water heaters have guarantee of 5-7 years on the inner tank. The heating element has a guarantee of 2-4 years. The overall product has a 2 year guarantee.
