Most Energy-Efficient Water Heaters for Your Home: Which One Is Right for You? 

Water heaters are energy-hungry because of the nature of their function, regardless of their fuel type. To keep your ongoing costs low and to reduce the blow to your power bill, purchasing a good-quality, efficient model is key. In your search for the best power-saving model on the market, it is prudent to stick to proven brands such as Crompton, V-Guard, etc.

Comfort and your comfort level, combined with the costs associated with it, is what an energy-saving water heater represents. 

The choice between a storage (tank) water heater and an instant (tankless) water heater depends primarily on how much hot water is used. Tankless heaters are certainly efficient and economical for families of two or three that do not demand multiple uses of water at a high-volume rate simultaneously, as doing so will consume more energy than a storage water heater. Accordingly, the small household of two can opt for tankless water heaters, as they obtain hot water instantaneously with little wasted energy; however, for the larger households (and where heavy or frequent demand is prevalent), it is advisable to consider a storage water heater, as the built-in tank may vary their levels, but it still offers families a way to reduce power costs and demand. Otherwise, when water temperatures drop, like in the winter or during the monsoon months - there is nothing worse than a cold body of water to dip into unless it is hot and comfortable, so selecting the right geyser for your requirements that may help lessen your electricity bill while providing warm water from a great energy-efficient brand makes sense.

Lower Your Bills: Select the Right Energy-Efficient Water Heater 

The water heater category selected is vital information for your power consumption. The well-known and reputable brands (i.e Crompton, V-Guard, Longway, Racold, and Havells) will provide you with tank and tankless water heaters which can accommodate various numbers of family members and usage behaviours.

It is safe to say, instant water heaters are to better serve a smaller household, whereas a storage water heater is to accommodate a medium to large family with capacity to meet the demand for continuous hot water.

3. V-Guard Brio 6-L LPG Gas Geyser

LPG gas geysers hold the advantage of having long-term operational expenses lower than water heaters which run on electric power. New LPG geysers available on the market are very efficient, transferring a significant amount of heat to the water while consuming gas, which is often less expensive than electricity.

The V-Guard Brio gas geyser comes with 9 safety features in the realm of gas geysers. There is overheat protection, a child safety lock, a 20-min cut-off timer, and a double solenoid valve. It is not an R&D unit either, and the safety mechanisms are functional and built into the unit, so the results should meet the expectation of operational safety, as described by my contact at V-Guard.

This unit has the additional safety of anti-frost protection and double ignitor pins built for safety.

The geyser does allow for control of the flame, and water flow can be adjusted to provide support to end-user functions during low water flow and pressure situations typical with homes where water is supplied at a poor rate.

Dimensions: 30W x 44H cm

Wattage: 12 KW

Ignition starts can be unsuccessful and inconsistent

3 Types of Energy-Efficient Water Heater

1. Storage Water Heaters: Larger portions are often available with storage water heaters, as the tank can often keep your water hot for a period of time, charging more electricity. They are also safe to use and offer reliable service in family homes. Brands available include V-Guard, Crompton, and Racold.

2. Instant Water Heaters: Instant water heaters work best with small family homes; they will save energy while keeping a high level of efficiency. Some popular and functional tanks we have used include the products of Havells, Crompton, and Orient Electric.

3. Gas Water Heaters: Gas models will often carry the least long-term cost in areas where gas is available and may be cheaper than power consumption for new electric tanks. Performance standards vary and offer good energy savings for residential purposes in comparison to the electric units.
