Rinnai RL94i-N tankless water heater reviews- If you’re concerned that you may need more hot water than standard 5 person home than this tankless water heater is for you. You’ll have no problem running multiple sinks and showers at the same time. And each shower is just a warm as the one before it.

The Rinnai RL94i-N is specially designed to combine high efficiency hot water with a refreshingly quiet operation which allows it to be installed essentially in any room or closet.

It’s commercial grade heat exchanger that’s so reliable it comes with an amazing 12 year warranty. Rinnai is so confident in this water heater that all parts and labor are covered for the first 5 years. Any company that is willing to cover all expenses for 5 years has my vote for a high quality product.

This tankless water heater is currently on sale on Amazon for nearly 37% off through this link right HERE.

Another very cool feature of this RL94i-N is that it’s compact enough to fit in your existing water heaters closet. You simply mount it to the wall and vented up through the roof or out an outside wall.

An easy way to save hundreds of dollars is by purchasing your own tankless water heater online then finding a qualified contractor / plumber second. At the bottom of the review I explain how to hire a qualified installer.

This tankless water heater is for :

A standard 5 person family with 2 bathrooms. Here is an example on how to add up your GPM’s in sizing a tankless water heater.

Example for the RL94i-N if you have 55°F tap water:

• Shower One = 2.0 GPM
• Shower Two = 2.0 GPM
• Dishwasher = 1.0 GPM
•             Total = 5.0 GPM

I found that the actual GPM’s with 55°F tap water is around 5.1 GPM’s.

killer machine,  November 15, 2011

By Yegor Podolyak (san Diego) -

I also have this product installed, although I’m a licensed plumber and did installation myself but it shouldn’t be any different if your unit was installed by a pro. I absolutely love the unit, I have to say that I’m very picky and hard to please kind of guy and I don’t have any of the problems this unit giving to the other guy, performance is unbelievable to this day I wonder how this little guy seems to keep up with upto 5 running units at the same time. Noise wise it’s probably as quite as working ….

Wonderful unit, no issues, November 24, 2011

By JimboPalmer “I tried to ramain childlike, all… (Greenwood MS USA)

When I needed to re-purpose a laundry room as a half bath, I needed to get rid of my tank water heater. Following the vent upstairs I mounted the unit in an upstairs bed room. 8 inches recessed into the wall, leaving 3 inches in the room. Now I have unlimited hot water, which it is very easy to change the temperature of. I freed up almost all the room the old water heater used and no one sleeping in the room has been woken up during use. The 4 inch vent …..

You bought a tankless water heater online now what do you do?

1. Call a plumber first

Tell them you have a new Rinnai RL75iN in your position and you would like a quote on installing this tankless water heater.

Note: if you don’t have a 120 volt electrical outlet near the tankless water heater you may need to call an electrician to install an outlet. No matter what type of water heater you pick you will need a 120 volt outlet nearby to plug into.

2. Pull a permit

Someone will need to pull a permit and set up an appointment with the town / city gas inspector ask you plumber to do this. The inspector will come to your home and check to see if the gas line is holding pressure before they place a tag on gas connect. Many people do not like having to pull a permit and contact the inspector on a home improvement projects. I understand that BUT, without this inspector’s gas tag, the gas company will look at your gas pipe and go home 100% of the time.

3. Call your Natural Gas supplier

Contact your natural gas supplier. A plumber can run all the internal gas lines to the water heater, but the gas company makes the last connection. After the gas company is done, your plumber will start up the tankless water heater. Make sure the training is in the contract, some plumbers may try to cut that out of the install.

What could happen when you start this process? Everyone is going to want to sell you tankless water heater, the plumber and the gas company. Why are they pushing to do this? They want to double dip, the want to put a profit on the tankless water heater and the install. If they can package the deal you have no idea how much your water heater really cost. They can show you a reduced price for the heater and increase the profit on the install. This happens every time you go to your mechanic, parts and labor.

Take control and buy your own parts and get quotes for the labor. You can do this just be clear in what you want done.

Plumber = Tankless water heater Installation should cover,

• Disconnect and remove existing water heater,
• Connection water lines
• Connecting gas lines
• Basic wiring,
• Venting outside (wall or ceiling)
• Pull permit
• Ask them to contacting the gas inspector and letting you know when they are coming so you can tell the Gas company (I got caught on this detail last year and lost another day of work).
• Start-up training.
• After its running you can talk about a possible maintenance contract.
