It is important to select the best 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 one: Durability Ability to withstand hard water Energy efficiency Pressure withstanding capacity Technology Safety features After-sales service.
It has a tank that stores water and when switched on, the water is heated to the temperature set, and can be used later for bathing. A low waiting time is one of its main advantages.
However, it will not deliver adequate hot water in areas with a cold climate. However, an instant 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 right capacity to buy.
Application Capacity In lts Inlet water temp. 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 Ferroli Blue 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.
The sacrificial aluminium anode provides additional protection of the element and the tank. 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 electric 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 low pressure withstanding capacity. Stainless steel is susceptible to corrosion in hard water conditions.
The Ferroli's electric 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 o C creates a perfect glass lining on the tank, ensuring a longer life. Always make sure that water and gas washers are in good condition, and when that is not the case- replace as needed. After parts replacement reopen all clocks and recharge the system to about 1 bar, and vent boiler and radiators.
Always test for gas soundness of all joints after completing any exchange of gas carrying components and carry out functional checks of controls. Always test water soundness of all joints, system pressure and the electrical supply.
In order to perform any parts replacement you will need to gain general access to the gas appliance- remove outer case. To do so, follow the steps below:. Or re-pressure expansion vessel to the charge value of 0, bar through the C valve.
Remove bottom connection from gas valve. Fit top and the bottom gas connections to the new gas valve. Find the water pressure switch and disconnect electrical connections. You should now note all the positions to the switch. Loosen all the screws should be two fixing the burner assembly to the D combustion chamber of the boiler.
The air pressure tubes should now be disconnected from the air pressure switch, its positions should be noted. Place a piece of cloth or some other absorbent material over rear of control panel to catch any drops of water that may be released when removing the flow meter.
Place a piece of an absorbent texitle over the rear of the control panel to catch any drops of water that may fall when the pump head is removed. Use 4mm allen wrench undo all B allen screws should be four in the head of the pump, Unscrew the pump head from the body.
Disconnect the e expansion vessel connecting pipe from the rear of the pump body by removing the clip from the left hand side. Disconnect the return pipe of the boiler and release the pump lower connection by taking away the clip. After each parts replacement you will need to put your boiler back into operation. In order to start your boiler after parts replacement following steps should be done:. After this all is set you will need to choose which operating mode you want to switch on: central heating and the domestic hot water production or just domestic hot water production- this mode is usually being switched on only during the summer.
The burner will ignite and your appliance will start to operate automatically, controlled by its control and safety devices. If you want to choose the domestic hot water only put the know into summer position. In the hot water mode only your appliance is will operate automatically when the domestic hot water will be drawn off. When after the start-up procedure correct completion, the burners still fail to ignite resulting in the boiler shut down and the warning lamps will light up, you should wait for about 20 seconds then move the knob to RESET position, hold it for a few seconds and then release it.
The reset electronic control unit will repeat the start-up cycle. In instances where you want to shut down your boiler for a longer period of time weeks and days you should close the boiler isolation gas cock, drain the water from domestic hot water and central heating circuits and turn off the electricity to the boiler. Alternatively, drain the domestic hot water system only and add special anti-freeze to the central heating system. Ferroli Combi, Modena, Optima, Falkon.
Troubleshooting Manual. Safety first! For greater energy savings and bigger comfort it is always advised to use a digital or manual room thermostat Attention! Differential air pressure switch The differential air pressure switch is very important safety device. Frost Protection The frost protection is a safety device which allows boiler to function properly in temperatures close to freezing point. Your boiler needs to be connected to the electricity for the two safety functions above to work to the boiler Boiler cleaning The outer white casing requires just a regular wipe with a soft duster or damp cloth will suffice.
Filling the system with water In the lower temperatures system pressure should be about 1 bar. The maximum output for central heating system adjustment The maximum output for central heating system adjustment should be performed electronically and by P adjustment screw useage starting from a cold central heating system.
You need to verify each time that the urner ignites correctly and that pressure values remain as adjusted or you will need to adjust pressure several times in short time interval The central heating flow temperature adjustment Central heating water temperature is adjusted by rotating the control knob.
The central heating flow adjustment The thermal head is the temperature difference between the delivery water and return water in the central heating circuit. The room temperature adjustment You can control the room temperature by moving the thermostat know to the proper value. Table 1. General fault finding table applicable for all Combi models Fault Action Solution No hot water Is the central heating?
Yes Reset the appliance, if fault stil exists replace the flow meter No central heating Is there hot water? Yes Replace external controls i. Yes Replace C. Yes Replace gas supply, pressure or gas valve No hot water and no central heating Open a hot tap to create a demand — is there a spark at the ignition electrode? Is fan running? Yes Replace air pressure switch or overheat stat if boiler locks out without sparking go to overheat stat No hot water and no central heating Is low water pressure light Flashing?
Yes Top up water to above 1 bar No hot water and no central heating Is fan running? No Replace low water pressure switch Table 2. No hot water. Is the central heating? Is there a tap symbol on display? Reset the appliance, if fault stil exists replace the flow meter.
