When it comes to buying residential electric water heaters, they are preferred by many people. They have become quite common since they offer convenience and the ease of installation. For many homes, there is not an existing gas line for a gas water heater, but virtually every home has electric, so this type can be installed faster.
Residential electric water heaters are made by a variety of manufacturers including A.O. Smith, Reliance, G.E. and many others. They are the next most common type after gas water heaters. The electric water heater can be purchased either as a tank model or as a tankless model. The largest consumption of heated water is for bathing.
Residential Electric Water Heaters Review
The residential electric water heater comes in a variety of tank sizes. The tanks are where the water is stored until it is needed. Generally available in sizes from 20 gallons to 100 gallons, the size that is chosen will depend upon the family size and hot water usage. Households that use a lot of hot water will require a larger water heater.
Tank electric water heaters have a tank that is insulated so that it can maintain a desired temperature for the water. The system heats the water and then it sits in the tank until it is ready for use. Periodic re-heating of the water will have to be maintained, as there is some loss of heat through the walls of the tank. Larger tanks lose more heat than smaller ones.
The tankless electric water heaters do not have a tank, thus the name. They heat water as it is required. Although they are preferred by some, due to the limitless supply of hot water, they are more generally not as efficient as a tank water heater. They are also much more expensive at the onset. Units can cost as much as $1,000 or more. They are more compact than typical tank residential electric water heaters. In addition, they have a longer life than a tank water heater. The tankless model usually lasts for about 20 years.
Advantages of Residential Electric Water Heaters
There are certain advantages and disadvantages associated with a residential electric water heater. Here are a few:
The electric water heater will heat the water quite quickly. They are also quite efficient at heating to the desired temperature that is set on the tank.
The electric is usually always available for connecting an electric water heater. There are very few places in the world today that would not be suitable. Additionally, if there is not a gas line already in place, adding one can be somewhat expensive.
Electric residential water heaters do not generate as much heat into the air as a gas water heater. This is a big consideration in the area in which the water heater will be installed. Electric water heaters are friendlier to the environment. They do not emit CO2 into the air unlike the gas water heater. This helps to protect the environment.
They do not require a flue or special installation.
Disadvantages of Residential Electric Water Heaters
There are typically two times of the day when more hot water is used. The morning and evening are considered “peak load” times. Residential electric water heaters contribute to the “peak load” time for the use of electricity.
Using an over-sized electric water heater will cause more energy loss since they consistantly heat the water to keep it at the desired temperature. The use of electricity for heating water is more costly than using gas to heat water.
If you are considering tankless electric water heaters, you should know they usually require more electricity when running. This means if you have an older home that it may not be able to provide enough electricity to the unit.
Another thing to consider when installing a tankless water heater is the installation cost itself. The plumbing as well as the electrical wiring must be taken into consideration. If it is not able to support the water heater, upgrades to allow installation can be quite expensive. For those with limited means, this may be an expense that is not viable.
There are many different aspects to be considered when purchasing and installing residential electric water heaters. Some types are more suitable than others depending on the points above. Choosing one after being fully informed of the advantages and disadvantages should make the decision easier. Have a look at this WaterHeaterReviewer Blog.
