Installation, Maintenance, and Longevity: Maximizing Your Geyser's Life

Installation

Location & Wall Mounting: Install the geyser using high-grade anchor bolts on a solid, load-bearing wall to which it is secured. It is advisable to keep the height of the geyser at around 1.8 meters (6 ft.) from the floor. Such installation would facilitate better functioning and easy maintenance.

Ventilation &Clearance: It is recommended that the geyser should be kept away from its surroundings at a distance of 1 to 2 ft. This will not only help the geyser for cooling purposes but also allow service of the geyser, etc.

Plumbing Connections: It is wise to use high-pressure pipes, multi-layered or stainless-steel braided. These pipes, with the help of good-quality washers, will ensure a better connection. Also, the inlet pipe should be equipped with a pressure release valve (PRV).

Maintenance

Anode Rod Replacement: The sacrificial magnesium anode rod should be examined regularly and replaced every one/two years to protect the tank from corrosion, even in areas where water is very hard.

Routine Descaling: The heating element and the inside of the tank should be cleared of mineral scale deposits (limescale) by flushing and cleaning once per year because these mineral scale deposits result in a reduction in heating efficiency.

Longevity

Install Water Softeners: Employ the use of a scale inhibitor or a hard water softener in your supply pipe if the TDS level of the water is higher, since these methods will effectively protect the heater's lining and the heating element.

Avoid Dry Heating: the geyser should be switched off in the absence of a water supply at all times. When starting up, make sure the tank is filled so the power doesn't burn out.

Power-down When Inactive: turn the unit OFF if you'll leave it for long periods of time or sleep, etc to avoid running the heater without the benefit of warm water and to reduce thermal stress on it through repeated ON/OFF.

FAQ

What is the ideal capacity for a water heater for a family of 3-4 members?

If you are a family of three to four people and want the possibility to have two successive showers while still being able to wash clothes using hot water, then a 15-litre to 25-litre electric kettle should meet that requirement. 

How important is the BEE star rating for a 25L water heater?

With frequent winter use of a water heater, it makes sense to get a BEE star-rated water heater. A four- or five-star rating will not only reduce your electricity bill A lot when you are running the heater on standby but will also help to cut annual energy bills by up to -0, 30%.

Can I install a 25L water heater myself, or do I need a professional?

To ensure a job is well done, you may want to rely on a certified expert. Putting in the 25L model heater would require high-pressure specialized plumbing, dedicated heavy-duty wiring, proper earthing, and installation only on load-bearing walls. Do-it-yourself installation can mean dangerous leaking water, electric shocks, and invalidating your warranty in the process.

 

Are instant water heaters a better alternative to 25L storage water heaters for Indian homes?

Among the common problems one usually runs into after having one for several years are scale buildup, corrosion, water leaks, and heating element failure. We recommend avoiding these kinds of issues by installing a water softener; replacing the anode rod every 1-2 years; draining the tank once a year; and routinely examining and testing the pressure release valve of the water heater.
