What to Look for Before Buying?

Tankless water heaters are trendy and somehow considered essential these days. Compared to traditional ones, they are more efficient when it comes to energy and costs.

It sounds pretty interesting, right? But not everything you see online is perfect for your home or commercial spaces. There are essential factors you need to consider before you finalize that purchase order for your first tankless water heater.

Size

Why should you bother knowing the size of the unit? It’s just easier to pick anything that look attractive with awesome stars from users, right?Apparently, you need to conduct a thorough research to know which one is suitable for you and your property. If you’re going to use it at home, check how many showers, tubs, sinks, washers, or applications you currently have.

It’s also very important to determine your household flow rate beforehand. Add up your appliances and showerheads to figure out the average supply your tankless water heater should produce. Look for a unit that could match your demand, and if unable to find one, then install multiple units if deemed necessary.

Energy Efficiency

One of the main reasons why consumers like you opt for tankless water heaters is to save energy and eventually costs. It’s just right to look into this factor closely when you are scouting for the best unit for your place.

Most brands emphasize this area, but one thing you need to check is the capacity of the water heater to keep up with the demand as the need for hot water increases. Look for something that only functions when you need it and avoid the ones that store up water as it is uses more electricity. Though any tankless unit can outshine traditional ones, it’s still best to end up with something economical.

Fuel Choice – Gas vs Electricity

This factor is crucial as this will determine not only the productivity of your unit but also your monthly cost. Gas, electricity, and propane are common choices for fuels. Accessibility influences the decision of users most of the time. Surely, you would prefer something readily available in your area.

For tankless water heaters, gas types are more expensive than the electric ones. Compared to the latter, gas-powered heaters carry more power; thus, this one is a preferred option of most residential owners. However, gas types usually need larger gas lines, which means it is way expensive than others.

Electric units, on the other hand, require detailed work but mind you, they are as efficient and durable as the gas types. Water heaters powered by electricity are easy to install and upgrade but with set limitations.

You have to look into the wires, upgrade instructions, and other safety protocols if you’re planning to use it for all applications at home.

Now, you can choose either of these two, but make sure to pick a unit with an intermittent ignition device. Through IID, you can easily switch on and off the pilot light and get the water heater to operate only if you need it to. This can help you manage energy wastes and manage your annual expenses.

Manufacturer’s Warranty

Why do you need to pay attention to this very minor detail? Indeed, buyers would sometime disregard this factor and focus more on other information. But as a wise purchaser, it is important to know the coverage of your warranty for future use. You’ll never know what could happen to your unit as time goes by.

Checking and comparing it with other brand’s warranty will save you from regrets in the long run. Keep in mind that when a manufacturer stands behind their brand and clearly indicates acceptable time frames and conditions, they firmly believe in the quality of their products.

By then, the assurance is 100%.

Maintenance

Securing tankless water heater units is surely a wise decision to make, considering the benefits you get instantly upon purchase. The durability of this type of product is tested to last up to decades. But of course, it depends on how well you maintain the unit you have.

In terms of maintenance, electric tankless water heater reviews indicate how easy it is to clean. You do not have to hire an expert and shed out some cash to dismantle parts on your behalf. Simply check limescale build-up and hard water deposits regularly for smooth operation.

Descale your unit from time to time for maximum performance. This doesn’t mean every day, of course, but you can schedule this every six months or once a year. Pick a unit that is easy to install and smooth to clean up for your convenience.
