How to Pick The Best Tankless Electric Water Heater

You need to consider a few things before investing in water heaters. Tankless heaters can be costly. So do a little research before buying. Here are some key points to look before purchasing a tankless water heater.

Select The Right Size:

Determine the flow rate you need in your home and then select the size. If you choose a very small unit, then it might not fulfill your needs. Manufacturers provide a size chart, and you can choose whatever is suitable for you.

Determine the flow rate:

You have to determine the flow rate that your household needs. The flow rate is measured on Gallon per minute (GPM). To find out your requirements, you have to know how many hot water fixtures will be used in the peak hour. Add up each accessories GPM and find the total one.

Temperature Rise:

If you live in a colder place, you need more water temperature. So some heater will need more time to deliver hot water.

Conclusion:

So these were some of the popular tankless electric water heater currently available on the market. My personal favorite is the Camplux Electric Water heater.
