Electric Water Heaters are available in both these Storage and Tankless Water heaters. Check out the list of top 9 Water Heater Electric and description of each one from below sections. We have shortlisted some top 9 best water heater electric type, from an ocean of hundreds and thousands of water heaters claiming to fulfil the same purpose.  

In a generic water heater, a 220 v electric circuit needed to heat the water. There are two electrical resistance elements present in the water heater; one in the middle and the other in the bottom. When the water temperature drops, the thermostat switch closes to allow current flow, and it opens when the water temperatures reach the maximum preset level. The maximum water temperature in the best electric water heater can be set to 130F to 140F, depending on the type of the heater. Or it can be set as low as 120F for energy-efficient performance.

When a hot water tap is open, cold water started running to the heater via a dip tube. The drops in the temperature trigger the lower thermostat, and it started flowing current to the bottom element to increase the water temperature. As the water at the top of the storage replaced by cold water, the top thermostat starts heating the upper element. This entire process carried on until and unless the water reaches the preset temperature. The basic mechanism of electric water heating is a cyclic process.

There are only three basic points you need to care about before buying a new water heater for your home. These three criteria also considered as the three generic pillars of a basic water heater model. These are-

  • Size of the water heater is the first and most important factor that one should keep in mind before buying a new one. Take your present lifestyle modifications as well as your potential changes for an account before buying a new water heater.
  • Nowadays, conserving energy has to be the primary concern of every citizen of the earth. All our effort should be towards a greener and sustainable living. Energy efficiency not only makes your home sustainable, but it also makes life affordable. How much energy your heater uses or how much efficient it must be is another important criterion for choosing a new water heater.
  • Type of fuel is the third and another important point to look out for. The type of fuel used in the heater will determine how much energy and cost it will take. The annual cost of water heater is actually based on the type of fuel used in it and the efficiency of the heater itself.

Tankless water heaters are suited for a single line only. The flow rate at the heads is 0.75 – 3 gallons per minute. If the water pressure is more than 75 PSi, then you will get warm water, and if the water pressure is less than or equal to 55Psi, you will get hot water at your sink pipe.

Most of the tankless water heaters can supply 0.75 -5 gallons per minute of water based on the model and brand. Since the capacity of the water heater is limited, you can use separate heaters for the sink, bathroom, garage and RVs. This will help you to save power, and you can get instant hot water at your sink. Since most of the water heaters have 98% thermal efficiency, you can grab one.

You can get Electric tankless water heaters from $150 – $2500. It is based on the capacity and quality of the material used. You can get nice tankless electric water heater under $150 for your sink. All the leading brands have tankless water heaters with a limited warranty of 1 year for all the components and 5 years of warranty for the heat exchanger. So it will not be a bad deal to have.

Almost all tankless water heaters require a separate hardwire connection. It is clearly mentioned in the box that you need a different hardwire connection, so you need to keep a separate sub-station for this device. Generally, the minimum power requirement is 30 A. 

Electric and electronic equipment require minimum maintenance, and there is no excuse for water heaters. But when compared to large gassed and tanked water heaters, this requires minimum maintenance. There are more chances for the deposition of limescale on the heat exchanger when it comes in contact with the water. Scale deposition may lead to circuit breaking in the device and may interrupt the water supply. So you need to check it once a month for uninterrupted water supply.

Electric heaters vary in size from 2 gallons to 200 gallons. Tanked water heaters are suitable for a large house and where there is a need for hot water. Tankless water heaters are limited in size and can serve small needs. Thus if you have a studio apartment or small home or RV or garage and need water to cater your needs, you can choose tankless water heaters.

Hot water is required at homes worldwide for many reasons. If you live in a cold climate, you cannot avoid the use of hot water at sinks, kitchen and bathroom. But enjoying hot water at all taps requires a price. The second-largest household expense in the US is for water heating. Water heating accounts to 14- 18 per cent of Home’s utility bill. Gas water heaters use natural gas to heat the water, and the electric water heater uses electricity to heat the water. Generally, gas water heaters are economical than hot water heater electric, but they cannot be used at all places. Let us compare and contrast gas and electric water heater.

elements Gas water heaters Electric water heaters
Heating rate Twice faster than electric water heater Heating rate is 1.5 gallon per minute for a mini tankless water heater
Operating cost Less More
Initial costs High Moderate
Installation process Complicated Easy
Recovery rate Shorter Longer
Long run cost Little Expensive
Space utilization More space Compact and lightweight


Department of Energy has found that the second-largest household expense is water heating and it accounts for 14- 18 % of a utility bill. So to reduce the cost, we use tankless water heaters as they produce instant water heater for all your needs. A tanked water heater will be more powerful than a tankless water heater as the stand by energy loss is minimum, and the thermal efficiency is 98%.

Electric water heaters use similar principles as that of the gas water heaters. When cold water comes in contact with the heating elements, the water is heated up. Hot water moves out of the tank through the outlet valve. Tankless water heaters are becoming popular at US home because it can deliver instant hot water on demand. Big energy savings associated with this electric tankless hot water heater. 

  1. There are two heating elements one at the upper and other at the lower part of the tank.
  2. Both elements are connected to the thermostat.
  3. Thermostats are set to a temperature range of 90 – 150 F depending on the brand. 
  4. If you use a high thermostat setting, more power consumption will be there.
  5. When the tank is turned on, water flows inside the tank through the cold inlet.
  6. Water comes in contact with the thermostats, and there is instant heating of the water.
  7. If the pressure of the water is more, then more water outlets can be expected. It is advised to use a pressure range of 55 Psi for a standard outlet.
  8. Since there is no air inside the tank, hot water immediately flows out of the hot water tap at the sink.
  9. When the hot water moves out, it leaves space for cold water from entering the tank. As a result, there is a continuous flow of water.
  10. If there is no thermostat, then scalding may occur in the tank. So you need an additional cold water pipe to adjust the temperature of the water.
