While many consumers have heard about tankless water heaters, they don't know much about them, and do not understand the many benefits that make them superior to traditional storage tank water heaters. Here we want to take a closer look at some of those benefits and see why tankless could be the smartest decision you ever make! Here are the top 5 reasons you should consider making the switch. Lifespan: Tankless water heaters are designed to last 20+ years with proper maintenance which makes them the most cost effective solution on the basis of years of service to cost ratio. The average traditional water heater is only expected to last 7-10 years. Life is expensive, and things wear out much sooner than most of us would like and our water heater shouldn't be one of those things. You and I depend on hot water daily and take it for granted until the water heater finally bites the dust. Why should that be a semi regular occurrence? It doesn't have to be when your tankless is built to last at least twice as long as a traditional water heater! Efficiency: When it comes to natural resources, we all want to be responsible and use them wisely and if we can save money in the process then that's incentive enough! By comparison, a traditional water heater is only about 57% efficient as opposed to tankless water heaters that can have an efficiency rating as high as 97%! The U.S. DOE estimates that tankless water heaters save approximately $90 annually in natural gas. Over 20 years this equates to saving $1800! Saving up to 40% of the money you spend on energy bills can certainly add up to serious money in your pocket over a 20-year span! Endless hot water: Not only do tankless water heaters conserve resources and save us money on energy costs, they have an added benefit of giving us an endless supply of hot water so no more running out of hot water in the middle of a shower! We've all been there my friend, everybody in your house is trying to get ready in the morning for school or work and sooner or later, the traditional water heater runs cold and there you are trying to decide if you have time to wait for the water to get hot again or if that shower is going to have to wait. Ugggh, who needs these kind of problems? Say goodbye to your worries when you have an endless spring of piping hot water that never runs out! Warranty: Most traditional water heaters only have a 6yr tank/parts warranty and in some cases labor may be covered for 1 year. Once the warranty expires, its usually not long before trouble comes along and your faced with costly replacement.....again. Many reputable tankless water heater manufacturers offer great warranties. Rinnai and others offer a 15-year warranty on the heat exchanger, 5 years on parts and one year on labor. If you purchase a Rinnai tankless water heater and register the unit with the factory within 90 days of installation, the labor warranty is extended to 5 years. No other manufacturer makes this offer currently. Rebates/Credits: Many gas utilities offer rebates to customers who switch from a storage tank water heater to a tankless unit and the rebates can be substantial. For instance, in Arkansas, Summit Utilities offers $500-$700 rebates depending on the efficiency rating of the particular model. Additionally, they have a free program available for senior citizens and low income individuals that can add $200 to that rebate! Section 25C of the inflation reduction act of 2022 gives taxpayers a $600 tax credit for any single energy property item which includes tankless water heaters! You do need to act quickly as this credit expires at the end of 2025. These are some really solid benefits that support a decision to go tankless. I had a professional tankless specialist company install one in my home several years ago and have never regretted the decision. I do strongly recommend utilizing the services of a company that specializes in tankless water heaters as they tend to be very knowledgeable about these products and how to recommend the right model for your particular application and also have the training and know how to properly install them so that you get the optimum performance and value out of your tankless water heater.
