The electricity consumption of a water heater or geyser depends on the amount of hot water used. Heat loss or standing loss of water heater to its surroundings in 24 hours is a criterion used by the Bureau of Energy Efficiency BEE.
To minimize the spending loss while using hot water, choose the right size of the water heater. The most efficient water heater will help you in reducing the losses. Mostly the best water heaters offer an extended warranty period and are energy efficient.
The names like Rheem water heaters, AO Smith heaters, and more are on every individual’s mouth.
First, consider your need and evaluate if you require a lot of hot water? IF YES, then go for a 50-gallon water heater, although some of the models have 80-gallon tanks. If not, you can go for the tank offering the storage take which can hold less gallon of water.
What Is The Cost Of Water Heaters?
Electric water heaters cost less to buy than gas heaters initially, although they cost more in the long run. Do not consider the upfront cost to add up the installation fee too while making the purchase.
Since water heaters are expensive, go for models that are energy efficient and energy star rated.
Energy-efficient heaters may cost more in the beginning but will be budget-friendly over the years. Choosing the water heater without anode rods could be a smart choice as it will last longer due to the absence of any particle inside the tank that corrodes. Do look at the warranty that companies offer before making the purchase.
