Key Benefits of Electric Water Heaters

Electric water heaters supply hot water whenever you need it. They are cost effective and efficient. Can you imagine the luxury of never running out of hot water? These heaters work as a tankless system. This means there is no need to unnecessarily heat a whole tank of water, since a tank is not required.

Have you had the unfortunate experience of running out of hot water when the house is full of guests? If you have, you know how inconvenient and frustrating it is. Imagine never having to worry about that happening ever again. A tankless heater provides a continuous supply of hot water. There is no tank, so it cannot run empty.

Water is heated directly, at the time it is needed. Electric tankless heaters have an element that heats the cold water when a tap is turned on. Water stays hot until the tap is turned off. The temperature of the water is pre-set according to your needs. Tankless systems use less energy, approximately 62% less than conventional water heaters, because they only work when needed.

The biggest consideration when installing a tankless electric water heater is what size should be installed. There are basically two types to choose from. You can choose a whole-house heater that is large and powerful enough to supply hot water to all household fixtures or you can choose to install point-of-use systems that supply hot water to specific fixtures only. Whole-house heaters and point-of-use heaters work the same but they differ in the quantity of water they can heat at any one time. Point-of-use heaters are cheaper and get installed at the exact point of demand.

You can determine the size of the electric heater you will need by determining how much water needs to be heated as well as the temperature rise required. Temperature rise refers to the difference in temperature between the set temperature of the unit and the temperature of the incoming water.

Each fixture in your home has a required flow rate. You can calculate how much water you will need by adding up all the flow rates of each fixture you anticipate will be open at one time. For example, if you anticipate that a shower head (with a flow rate of 2.5 gallons per minute) and a hot water faucet (with a flow rate of 0.75 gallons per minute) will be open at the same time then the total flow rate required will be 3.25 gallons per minute.

One water heater may not have sufficient capacity to provide hot water to all the fixtures in your home. This is especially true for people living in colder parts of the country where the groundwater temperature is significantly lower. In this case, two or more heaters may be required. This is why it is very important to calculate your heating requirements carefully up front.

Electric water heaters will save you money and provide you with hot water whenever you need it. An additional benefit is the space saving as there is no need to store a large tank.
