Tips to Ensure Optimal Performance from Your New Tankless Water Heater

As the second-highest contributor to your energy bills, water heating costs should certainly be a concern. If you had the chance to cut back on your bills, wouldn’t you jump on that opportunity? After all, who wouldn’t want to save on water heating costs?

One proven way to make this a reality is to install one of our quality Rinnai tankless water heaters. However, before you take the plunge, follow these tips to ensure optimal performance from your new tankless water heater.

Size the Appliance Correctly

It’s important to know what size water heater to invest in for better energy efficiency, reliable performance and a more economic purchase price. To size a tankless water heater, you need to know the maximum temperature rise at a given flow rate.

To determine the flow rate you require, add up the gallons per minute of each hot water device you plan to use at the same time in your home. For instance, you may want to be able to take a shower (2.5 gallons per minute) while running the dishwasher (1 gallon per minute), meaning you need a tank with a minimum flow rate of at least 3.5 gallons per minute.

Because most hot water appliances call for 120-degree water and incoming water is usually about 50 degrees, you want a tankless water heater that can provide a temperature rise of at least 70 degrees.

If you’re still confused, we can help you with your calculations when you decide to purchase a tankless water heater.

Choose the Right Fuel Type

Your choices are natural gas, propane and electricity. Where available, natural gas is the best option. Propane is a great choice where natural gas rates are high. Electricity is almost never the most economical fuel.

Consider Minimum Flow Rate

The water heater you choose must have a low enough minimum flow rate to keep your water hot even when you lower the flow rate at the tap to a mere trickle. Minimum flow rates range from 0.5 to 2 gallons per minute and a lower number is better if you want optimal performance from your new investment.

Insist on Professional Installation

Tankless water heaters are complex units to install. Never attempt it yourself, and when you hire a professional, make sure they are highly trained and experienced with this sort of job.

Make Sure the Unit is Vented Correctly

Ventilation is a concern for natural gas and propane-fired tankless water heaters. Proper ventilation prevents backdrafting, a dangerous occurrence that could bring combustion fumes back into your home. Make sure your system has sealed combustion and direct ventilation to prevent backdrafting.

Consider a Point-of-Use Model

In small homes, one whole-house tankless water heater is sufficient. However, we recommend point-of-use units in bigger homes. For example, if you install a small tankless water heater near the master bathroom, your sink and shower water heats up almost instantaneously. This adds convenience and comfort while reducing water waste as you wait for the water to heat up.

Maintain the Unit Regularly

Just like regular water heaters, tankless versions require periodic maintenance. Schedule tune-ups as often as the manufacturer recommends in order to help you get the most from the potential 20-year lifespan of your tankless water heater.

Reduce Your Hot Water Use

Low-cost ways to reduce hot water consumption include fixing leaks, adding pipe insulation and installing low-flow plumbing fixtures. You should also consider replacing old hot water appliances like the dishwasher and washing machine with energy-efficient upgrades to boost the performance of your tankless water heater even more.

Combine Tankless Water Heating with Other Energy-Efficient Technologies

Solar powered water heating and drain water heat recovery are two energy-saving techniques that preheat the water traveling to the tankless water heater. This helps speed up the water heating process so the delay shrinks between calling for hot water and it actually arriving.

In the end, no matter how you operate your tankless water heater, you can count on endless hot water every day! We just want to make sure that you know how to get the most from your investment from day one.

Maintaining your Rinnai Tankless Water Heater in a Hard Water Area

Vinegar is used for…….?

Would you believe, cleaning a tankless water heater?

From Wikipedia, the free encyclopedia

Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria.[1] Vinegar is now mainly used as a cooking ingredient, but historically, as the most easily available mild acid, it had a great variety of industrial, medical, and domestic uses, some of which (such as a general household cleanser) are still promoted today.

Yesterday I was talking with an industry professional who had raised this concern about using a Rinnai tankless water heater in hard water areas. For him he had heard the concern stated so often that it was almost beyond discussion.

The reality is he was correct in his concern about hard water. When it is heated it leaves a mineral build up on the side of the internal components. The hotter the water, the more severe the problem. This is true for all water heating devices including conventional tank style water heaters.

Fortunately, with all Ultra and Luxury series units, Rinnai includes an isolation valve kit. This kit has valves that permit the unit to be isolated from the home’s water while a vinegar or citrus mixture is used with a small utility pump for a short period to clean the internal components back to the condition they were in the day they were installed.

Who would drive a car and not have the oil changed periodically?  Same situation.

Properly maintained a Rinnai tankless water heater should last twenty years. Compare this to the alternatives and I think you will agree that the perceived major weakness of tankless technology is in fact one of its greatest strengths.

Are Tankless Water Heaters Worth It?

Tankless water heaters worth it?

I just reread an article from Consumer Reports posted September 2008. Not only is it OLD but its conclusions are highly flawed!

The world of 2008 no longer exists. Water heaters and costs of those units have exceeded the inflation of tankless units by a HUGE number. In addition the federal regulations of efficiency standards is due another major increase next year. Whatever logic for not recommending tankless technologies has long ‘left the building.’

I am also tickled that Rinnai was not tested in their report. The quality that Rinnai had then and has today may have caused a different outcome.

Let’s discuss point by point. offers a quality line of Rinnai tankless water heater for all gas instantiations. Many of our customers purchase from us and then find a qualified installer. This seems to shave literally $$$ from the price difference with conventional tank water heaters.

With a 12 year warranty and a 20+ year life expectancy you can compare the price to that of installing 2-3 tank type heaters. Also, the energy savings is huge and getting HUGER!

Rinnai products maintain temperature to within 2 degrees. PERIOD.

We offer an affordable Flushing Kit that should be used twice a year to maintain a clean system free of mineral build up. Rather than this being a weakness I strongly argue it to be a strength. Who would not change the oil in a new car or rotate it’s tires? The process is simple and the cost is miniscule.

Quite simply I could not argue more strongly about the conclusions! I have a Rinnai in my house and I LOVE IT! Unlimited hot water . For me it was a clear no brainer.

Always Go for Quality When Buying a Tankless Water Heater

Looks like I may be a snob?

When I was a young man in the 60’s the expression “Made in Japan” was another form of saying “made of junk!”

Fast forward to today and that same expression means “made of quality.”

I am not sure when things changed but I feel pretty good buying expensive products like cars and televisions if I know the country of origin is Japan. My experience tells me that along with the perception Americans have in general.

Until very recently, the only gas tankless water heaters of note came from Japan. I now see the floodgates opening with products from China and Korea. That concerns me.

I have been approached by some factories in China to import and brand their products. I must admit that the prices made my knees shake. The difference in costs are pretty substantial.

I then began the process of checking out feedback and comments on similar products. Not so good.

More than once someone suggested that they were a quality control guinea pig. Not so bad for a consumer who wants to install tankless on the cheap but you have to feel sorry for the professional who talked their customer into it.

Since I have a history of going to tankless manufacturers sites I find the I am being bombarded with some of these manufacturers.

Maybe someday, but not today.

I know Rinnai and I know the services they render. As the old expression goes “If it’s not broken, don’t fix it.” Rinnai has years and years of history under their belt and when I sell their products and they are installed properly, I know I have a happy customer.

I shudder to think of what could happen. The stuff of nightmares.

And yes, Rinnai is Made in Japan!

Explaining Tankless Water Heaters, or Not.

Anyone who has read any of my blogs will understand I have a love affair going with tankless water heaters in general and Rinnai units in particular.


On the surface it is simple; unlimited hot water.

You simply will never run out of hot water. NEVER!

It’s like describing a favorite color. Sounds simple but can be more than a challenge.

I recently ran across a unique marketing campaign by the Rinnai division in Australia.

I like checking in with both Australia and New Zealand’s Rinnai sites as I find they experiment with products there prior to being sent to America. I actually wish I could get my hands on some of their products for myself. Pretty neat stuff.

You may be amused at the way the commercials deal with the unique selling points of Rinnai. Not to be missed is the issue of quality.

Increasingly I am seeing Chinese products flooding our markets. I am more than a little concerned about the quality of these units. Of course there is little opportunity to discover this fact without doing a lot of homework. The products are sold on price ONLY. Just check the feedback scores.

Also, they offer little or no hand holding after the sale.

Rinnai has been extremely concerned about their product’s image since day one. Installers must attend

classes to learn the nuts and bolts of the technology. I have found NO issues when properly installed.

When someone does it ‘on the cheap’ it often ends very badly.

…..tankless water heaters let you shovel your driveway and stand under a hot shower forever.

….tankless water heaters let you be the 4th person in the house to wake up and shower…forever.

…tankless water heaters let you experience the color green, as in money in your pocket!

It has almost been one year since we were given this accolade.

What it means is that Rinnai looked deep and hard about who they wanted to see promoting their brand on a national level over this very new arena called the Internet.  I feel these many months have proven their choice was a good one.

Over that period, and a very tough economy we have been able to enter the Million Dollar sales club with Rinnai.  Last year we exceeded $1.4 million. Thank you Rinnai!

I think it important to indeed say thank you to a partner that supplied us with an excellent product to sell.  The times that I have had issues with quality are extremely few.  In fact the likely problems generally fall back on poor installations.

We as a partner are very careful in how we sell these sophisticated products.  Previously we worked with our local rep to learn the product inside and out.  We hosted many training sessions for the local trade so that they too were aware of the uniqueness of the product.  The training never ends and we too are keeping up with the changes that are introduced.

Tankless water heaters are not something to be sold by a mass merchandiser.  This is not a product that should be picked up at a Sam’s Club or even a Lowes or a Home Depot.  This is a product that needs checks and balances that only exist with our industry.

How Rinnai products are marketed is special.  Since the day of Paul Harvey they explained to the home owner what this product was and what it did.  They have always worked closely with the trade to create a very positive image.  They know how burning bridges forever ruins the marketplace.

Thank you Rinnai for believing in and
