Things to Consider before Choose the Best Electric Tankless Water Heater?
Here, you are well aware of some best of the best electric water tankless heater. But still, the problem remains the same, which one is best for your home?
So to solve this problem, we have compiled a brief and concise buying guide about the electric tankless water heater. By following this guideline you can easily decide and choose the best one for your home.
Let’s get started!
There are two crucial factors that you need to consider before purchasing a tankless water heater’ that are:
- The flow rate
- The temperature rise
The Flow Rate:
Flow rate means the rate at which the hot water flows through the fixture or appliance.
So before buying a hot water heater, first determine your hot water needs. You can do this by listing down the total number of appliances or fixture you will be using simultaneously such as using the kitchen sink, doing laundry, or taking shower at the same time. Then add up each flow rate in order to determine the total flow rate.
Such as the average GPM usage for kitchen sink, washing machine, and bathroom is 2.5, 1.0, and 2.5GPM respectively.
The Temperature Rise:
Temperature rise is actually the difference between groundwater temperature and the desired hot water output temperature.
Let me add to your information that groundwater temperature varies throughout the world. Even a single country would have different ground temperatures in different cities. It can range from the mid s30s to the upper 70s measured in Fahrenheit.
Usually, the internal home water temperature ranges from 110 degrees to 120 degrees. If you want to determine the temperature rise, all you have to do is to subtract the incoming water temperature from the desired internal water temperature. For instance, 55 degrees is the incoming water temperature whereas your desired hot water temperature is 120 degrees, so the temperature rise would be 65 degrees.
Luckily all the tankless heaters manufacturers have charts that you can use to help you find the best one for yourself based on temperature rise.
A quick tip:
Electric on-demand water heaters are ideal for those families who looks for energy-efficient water heating solution. Tankless water heaters are quite expensive but you can take long-lasting benefits from them. Not only you, but even your generation would take advantage of it. So choosing the top electric tankless water heater is a quite sensitive decision as it’s a one-time decision. Do it wisely!
