Top 5 Reasons to Replace Your Hot Water Heater with a Rinnai

Is it time to replace your old water heater? Or are you considering upgrading to a tankless water heater and unsure which brand to go with? Look no further, as we are here to assist you in making your decision!

Rinnai is the first major tankless brand manufactured in the U.S.A. and built on quality. According to Chauncey Crail and Lexie Pelchen in a Forbes article, Learn The Major Pros And Cons Of A Tankless Water Heater, “ Rinnai is the most popular tankless water heater manufacturer in North America.” There are many different series to choose from to meet your needs and your budget. Rinnai is a reliable name in natural gas and propane tankless water heaters. Here are the Top 5 Reasons to Replace Your Hot Water Heater with a Rinna.

Save Money

How are you going to save money buying a Rinnai water heater? They’re so expensive! Yes, the initial start-up investment can be a little pricey. However, they are significantly more energy efficient. Fresh water is heated on-demand–no waiting on the water like the traditional tank styles. The heated water will not be sitting in a tank, therefore, no wasted gas or electricity means the operating costs have decreased, when you use less energy, the less amount of money you will be spending especially if you live in an area where energy costs are high. Right now, with the rising costs of everything today, especially electric rates, propane or natural gas tankless water heaters are the way to go. While both of these prices are increasing too, you won’t be using as much on the tankless heater because it is only heating the water as you need it.

Continuous Hot Water

Have you ever gotten in the shower after forgetting that you had just done a couple of loads of laundry, using hot water, and now you aren’t able to enjoy the warmth of the hot water because it has run out?! With a Rinnai, you will have an endless hot, fresh water supply. If sized correctly to your home's needs, a tankless water heater will be able to provide unlimited hot water. Fresh water will always be delivered because the water is not sitting in a tank and getting rusty. P.S.- look for our next blog post on how to choose the correct sizing for your home and family needs!

Save Space

Rinnai tankless water heaters are compact versus traditional tanks. The standard size for a tankless water heater is 28 inches tall by 20 inches wide and 10 inches deep. Now this varies by the size that you get as there are many different models for you to choose from. Traditional tanks hold between 40 to 60 gallons of water and generally measure about 60 inches tall and 24 inches wide. So as you can see, they can save you floor space and be hidden anywhere. You won’t have an unsightly huge water tank taking up space in your utility closet, giving you room to store more food, cleaning items, or whatever else you would want to put in there. Rinnai’s can be installed in a garage, attic, basement, or utility space without sacrificing floor space. It’s a great option if you have limited space.


Who wants to spend money on big, ugly, water heaters every 8 to 12 years?! Even if there is a minor issue with the traditional tanks, you have to replace the whole thing because there is no way to get inside and fix it. Rinnai’s are designed to last and be repaired and generally last between 20 and 30 years! Almost every part can be replaced to ensure that the unit lasts longer. Keep in mind that Rinnai is built on quality and being able to replace almost every part for the fraction of the cost of a traditional tank, is a huge plus! When you purchase a Rinnai, it’s a great long-term purchase for your home that will leave you wondering why you didn’t make the switch earlier.


Yes, you read that right, they are green! How you may be asking! Well, since there isn’t a tank, you’re not wasting money on heating the water that you aren’t going to use! According to Crail and Pelchen in the Forbes article, Learn The Major Pros And Cons Of A Tankless Water Heater, “The US Department of Energy reports a tankless water heater is a 24% to 34% more energy efficient than storage-tank water heater as long as you use around 41 gallons of water per day. However, even if you double that amount, they are still 8% to 14% more efficient.” Forbes goes on to recommend that when you are looking at tankless water heaters, “look for an Energy Star rating- a government-certified rating that means the model is within the top 25% for efficiency among all models manufactured.” Not only will you be saving money, and have a great unit for 20-30 years, but you will also help to save energy!

Does the price intimidate you or you’re still uncertain about buying a Rinnai at full retail price? Remember that there are many different series to choose from to meet your budget and family needs.
