It is important to select the right water heater for your home, one that performs reliably and safely for many years to come. Please keep the following aspects in mind when choosing a water heater:
a) Electrical Storage Water Heater –A storage water heater will deliver hot water at a specified, pre-set temperature upto 75°C. It has a tank that stores water and when switched on, the water is heated to the temperature set, and can be used at anytime later for bathing.
b) Electrical Instant Water Heater –An instant water heater heats the water as it flows through the device. It will give hot water in minutes with low waiting time. However, aninstant water heater will not deliver adequate hot water in areas with a cold climate. It only 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 capacity of the water heater to purchase.
|Application||Capacity (In lts)|
|Inlet water temp. >20 C||Inlet water temp. <20 C|
|Kitchen||1 L or 3 L Instant||6 L or 10 L|
|Bathroom||15 L or Above||25 L or Above|
|Shower panel||50 L or Above||70 L or Above|
|Bathtub/Jacuzzi||100 L||100 L or Above|
Hard water will cause scale deposits on the heating element of your water heater, and 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 helps deliver increased heating efficiency.
Water heaters with the conventional copper heating element require regular descaling or replacement because of the deposition of calcium on the element, over a period of time.The Ferroliblue forever heating element is coated with silicon enamel which completely isolates water from the metal. This prevents deposition of calcium, thereby improving the durability of the element.There is also a sacrificial aluminium anode for 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 and will need to be replaced only when completely corroded.
The inner tanks of electrical water heaters are made with different materials such as copperand stainless steel. A copper tank is not suitable for high rise buildings due to low sustainability of pressure. 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 870o 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 tensilestrength of the inner tank, the thicker its material the more its tensile strength.Ferroli’sblue 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 as it has outstanding pressure resistance performance that extends life of the tank and enhancesits safety.
Most water heaters will not have any temperature indication and therefore the customer has to physically touch the hot water to sense the water temperature, resulting in burning and discomfort at high temperatures.Ferroli water heaters are equipped with a digital analoge display which willprovide the temperature of the hot water inside the tank. The regulating knob allows the customer to set the desired water temperature, from the ambient temperature to a maximum of 75 degrees. The Ferroli water 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:
Energy consumption in water heaters is lower than other household appliances since water heaters work for a very short time compared to other appliances such as air conditioners, refrigerators and TVs. You can verify the energy saving label on the product by looking at its BEE star rating.Ferroli water heaters have high quality injected PUF insulation that is far superior to that of other water heaters and serve to conserve heat longer, giving high savings on energy. Most Ferroli water heaters are certified by Bureau of Energy Efficiency and have the energy efficient BEE 5 star rating. Some of our storage models have a rating that is 10% higher than the requirements specified for a 5 star rated product– the highest energy efficiency rating in the market.
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 years guarantee.
