Longer Warranty Period

It need not be not fully true, but the longer the warranty on the electric hot water heater, heavier the gauge metal that are used for its making. There is every chance that the material on the product would be of higher grade. So the warranty length should be your first consideration.

No Of gallons

The capacity of the tankless water heater should be your second consideration. If you use presently a 40 gallon tanker and found running out of hot water, better go for a 50 gallon water heater. Additionally, you have a longer warranty period, say 10year or will make you comfortable with the appliance for a quiet number of years.

First Hour Output

The next item is the first hour rating, which gives you the information of how much hot water the electric hot water heater is going to deliver for your use in the first hour. This rating is not something most people ignore to check, but remains a significant point of consideration.

Tanklesss

If your are going with an electric hot water heater, you might consider buying an electric tankless hot water heater which will bring down your heating cost further

Energy rating

Other important criteria before buying electric hot water heaters is the energy rating for the water heater. This will indicate how much you are going to save on energy using the heater. This apart, you will be eligible for rebates from utility companies, if your new electric hot water heater has a higher energy rating.
