What Makes a Water Heater Brand Great?

When determining a water heater brand for your next big purchase, these elements could weigh heavily on your decision.


With today’s technology, there is no reason why any brand should offer a major appliance or product that is not energy-efficient.

Consequently, they are one of the second-highest products that account for total household energy consumption.

So, finding one that uses less energy is vital. Not only will it save you money on your monthly bills, but it will also reduce your overall carbon footprint.  


No one wants to have their water heater quit or have performance issues. Choosing an exceptional water heater brand means finding a reliable and long-lasting model, so you don’t have to worry about its performance or operation.

Water heaters should provide hot water when you need it, without worrying about taking too long in the shower or running too many loads of laundry. 

Warranty Coverage 

Purchasing a water heater is not a regular occurrence. These products can last anywhere from 8, 12, or even 20 years, depending on the style and model.

A reputable manufacturer will offer customers exceptional warranty coverage if they face any problems or issues with regular operation during the unit’s lifetime.

When choosing a new water heater brand, there are some factors to keep in mind. Of course, water heating needs vary by household, so be sure to ask yourself these questions when looking at popular water heater brands:
