Things to consider before buying the Best electric tankless water heater
Energy conservation is the buzzword today. Not only does it keep your power bills down but it also is good for the environment.
It is no wonder many are opting for the best electric tankless water heater that they can afford over the space-hogging conventional water heaters.
The electric tankless water heater reviews tend to confuse. When you are looking to buy an on-demand hot electric water heater, these are the things to consider-
Incoming water temperature
If where you stay the incoming water temperature is cold, it will drastically affect the flow rate of your inline electric water heater. Cold water flows through the electric heating element and gets heated.
If the incoming water is too cold, it will take a longer time to heat with the same power and so the flow rate will be low. You need to go with units that are powerful enough to handle low water temperatures in cold areas.
Number of points of use
If you live in a large house with multiple points of use, you need to go for a whole house electric tankless water heater which is considerably more powerful than the ones that are used for smaller dwellings.
More power translates to higher flow rate and thus you can easily run 3-4 showers and hot water faucets (for washing machines, sinks, etc.) simultaneously without experiencing a drop in the flow rate or temperature.
Ease of use and smart technology
The best tankless electric water heater today has a host of advanced electronics that controls the flow rate and heat giving you a consistent supply of hot water while saving on energy consumption.
Many come fitted with LED touch panels that are very convenient to operate.
Cutting edge tech has made heating water-efficient, energy-saving and user-friendly as never before. So, it is important to consider if your instant electric water heater has incorporated the latest smart technology.
