Rinnai RL75i-N tankless water heater is simply amazing. They are 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 36% off through thislink right here.

Another very cool feature of this RL75i-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 an qualified installer.

Rinnai RL75i-N Reviews:

By mersj

4.0 out of 5 stars Just switched to Rinnai tankless – so far so good., Dec. 9, 2011 –

 My gas hot water heater just died. Got quotes to replace with similar. Quotes ran from $1800 to $1250 installed. The tankless unit priced out at $2000 installed which included adding a larger gas line and tapping into electric. $300 fed tax credit, $100 from Rinnai and $150 from my natural gas company gets me to $1450. So for $200 I made the leap to tankless and should save at least that much in gas first year.

5.0 out of 5 stars Great but…, December 9, 2011 By -

Excellent way to heat water for a house up to three bathrooms, but it can take a solid sixty seconds of running water from a kitchen faucet to initially get hot. This may not sound like a long wait, but try sitting at your sink for sixty seconds and see how it feels. Plus if you are in an area with expensive water, it can get costly.

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).
• Startup training.
• After its running you can talk about a possible maintenance contract.          

About Jarrod: I spent 12 years working as an HVAC Commercial Sales Rep. My territory was Boston, MA to Bangor, Maine. After 5 years of cold calls, doors being slammed in my face and dealing with more problems than sales, I started an internet eCommerce, which led to a warehouse, which led to a Brick and Mortar
Store. Between the two businesses I sold a large selection of home improvement products including lights, faucets, sinks, water heaters, heating equipment, ventilation & air conditioner equipment, bathroom fans, dehumidifiers and compact and mid-size appliances amongst others. When my daughter was born
the 60 + hours in the office (not including the late night emails done on my
smart phone) were taking a toll on me mentally and physically. So I have down-sized the company and now I’m spending more time doing what I liked best: talking about the home improvement products that I know, understand
and have sold in the past.
