The GPM is more than just adequate, ranging between 4.0 and 4.4, to cater to the versatile needs of a household. A lot depends on the temperature of the inlet water.

Buying Guide: Things You Must Consider While Buying an Electric Tankless Water Heater

Electric tankless water heaters are selling like hotcakes. They have emerged as safer, cheaper, and more effective alternatives to storage tank models. Cashing in on the hype, several companies have thrown themselves in the ring and launched their own versions of tankless electric water heaters.

As a result, a trend of commoditization has picked, and the market is seemingly flooded with water heating models of all sizes and specifications. This confounding variety has presented a conundrum for buyers; the conundrum of buying the right water heater for their needs.

Through this buying guide, we go over all the important aspects in detail that one must consider before buying an electric tankless water heater. We aim to cut through the confusion, help you identify the red herrings, and simplify the complex decision for you.

1. Mind the Temperature Range.

Tankless water heating units perform the best when they aren’t required to raise the temperature beyond 30F. Even the most powerful units with the most cutting-edge features and a reasonable flow rate are capable of raising the temperature up to 50F only.

Given so, we would advise you to buy a tank or choosing a gas-powered unit if you live in areas with cold temperatures. These units are capable of higher temperatures rise and can provide hot water on demand.

If you live in moderately cold regions or plan to use a heater during spring or summer months, an electric tankless is an ideal option.

2. Compare the Flow Rates.

Flow rate is an important deciding factor when buying a water heating unit. Notably, different faucets and appliances require different amounts of water.

If your requirements are limited to taking a bath or dishwashing, a GPM of 3.5– 4 will be good to go. If you are looking for a unit that can withstand multiple requirements in a day, nothing less than 6GPM will work.

Below is a chart that lists out the demand types and the suitable GPMs in a row. Take a look.

3. Size and Brand Matter.

Water heaters come in a variety of sizes. Before making a purchase, measure the space where you’re looking to install or mount a heater. For smaller spaces such as under a bathroom sink, you will be required to invest in compact units.

In the list above, we have mentioned a few compact sizes for you to choose from. On the contrary, if you have ample space, you can also opt-in for mini-tank heaters.

Brands are brands because they bring the best of quality to the table. By choosing a branded heater, you will bring in a guarantee of quality, trust, and a promise of high customer experience.

4. Take Note of the Materials Used.

Traditional water heating units are built using materials that result in a buildup of limescale over a period of time. Getting rid of this chalky substance requires annual maintenance. The advent of new technologies, such as infrared, has changed things for the good.

Modern water heating units are good at tackling limescale and don’t require regular maintenance. Depending on the intensity of the incoming water, you may want to adopt an infrared water heater; however, note that such a unit will be pricey and feature a low flow rate.

Water Heater Maintenance Guide.

How to Take Care of Your Electric Tankless Unit?

Maintenance is arguably the most overlooked aspect of using a water heating unit. Make no mistake that a well-maintained unit works efficiently and allows you to derive sustainable value from it.

Below, we have a curated a step-to-step guide on maintaining an inline water heater. The entire process is divided into actions in a pecking order to help you go through the chore with utmost safety. Take a look.

Step One:

Turn off the power supply to your heater before everything. Remember that there’s nothing as important as your safety.

Step Two:

Next, turn off the three valves attached to the unit: the cold water valve (most likely to be blue in color); the hot water valve (most likely to be red in color); and the main valve that supplies water in your house.

Step Three:

You will notice the port caps around the purge valves of both hot and cold valves. Remove them gradually using the T-shaped handles.

Step Four:

This step involves attaching the hosing lines, for which you may be required to check instructions in the user manual. You might as well need a sump pump to connect hoses and flush out the water from the valves.

Note that if your unit didn’t come with hosing lines, you could buy them from any hardware or plumbing store at easy rates.

Step Five:

Now, open the purge port valves by toggling them perpendicularly to cold and hot valves.

Step Six:

Choose a safe, non-toxic cleaner to flush down the dirt from the valves within the unit. As an option, you can choose undiluted white vinegar as your go-to cleaner to get the job done.

Flushing and draining procedures are illustrated clearly in the user manual, so you can take all the necessary help from there. Allow this process to take 45 minutes for a thorough clean-up.

Step Seven:

Remember those T-shaped handles. Use them again, but this time to close the purge port valves once the flushing gets over.

Step Eight:

Disconnect the hoses now from your unit’s valves.

Step Nine:

Put the caps on the purge valves and lock them firmly without damaging the ports or the washers.

Step Ten:

Usually, it’s the standard process of cleaning a water heater. Still, it might differ from heater to heater.

Step Eleven:

Towards the end, turn on the hot water tap and fixtures slowly to let the air pass through the pipe. This is a minute-long process until you see and hear the water running.
