Rinnai R75LSi Natural Gas Indoor Tankless Water Heater Review

 

The Rinnai R75LSi Natural Gas Indoor Tankless Water Heater is one of the most popular tankless heaters on the market today. It was designed to be able to present a whole home hot water solution for instant and limitless hot water for most American homes.

It’s not the cheapest model, and it doesn’t have the most features, but it was never designed to have either. It was designed to do a great job for most homes at a good price. Does it succeed? Let’s have a closer look.

Rinnai, the Warranty and Getting a Heater that lasts a Long time.

Rinnai are a company that specializes in gas hot-water appliances, and have been around for over 90 years. They are one of the brand leaders in the water heating world and over the decades have earned a reputation for quality. As a case in point Rinnai offer one of the best warranties out there – for residential use the labor is warrantied for 12 years and the parts for 5 years.

Most of us never want to think about water heaters once we have bought and installed them. We just want something that keeps on doing a great job without fuss, and does so for a very long time.

On the whole one of the advantages of Tankless water heaters over storage is the longevity you get with tankless, and choosing a top brand like Rinnai will get you more longevity. The added bonus being a longer lasting heater saves you more money too.

Installation

One of the key features of this model is a good compact and simplistic design, so the Rinnai R75LSi can fit virtually anywhere. The whole unit is only 14 inches x 10 inches x 26 inches, and is a fashionable brushed aluminum in finish – not that you’ll likely be spending much time looking at it. As well as the obviously needed natural gas line in, water supply in, electricity in, and hot water out, you’ll need to put it next to an outside wall so it can vent out.

That said its compact nature means you can easily mount in pretty much…

Ecosmart ECO 27 Electric Tankless Water Heater Review

The Ecosmart ECO 27 Electric Tankless Water Heater is at the time of writing the bestselling Tankless Water Heater on the market.

It is an electric water heater and it’s important to note before we go any further that gas tankless water heaters deliver much greater energy savings benefits than electric ones. If you have gas, we recommend going gas if you can afford the extra upfront cost. It’ll save you a lot more money in the long run.

Saying that, a lot of houses don’t have a gas supply and in that case you’ll be looking to go electric. And in that case it’s vital to get an electric water heater that (a) Doesn’t cost too much upfront and (b) Saves as much energy (and therefore money) as possible over the long term.

Judging by its sales the  Ecos,art ECO 27 does this better than any other. But does it really do the job? Lets take a closer look and see.

Who Would the Ecosmart ECO 27 Electric Tankless Water Heater Be Suitable For?

The Ecosmart ECO 27 is designed to work in climates where the incoming water temperature can drop as low as 45 degrees Fahrenheit. It is well suited for  dwellings or homes within the colder northern parts of the United States as well as in Canada, but also for homes within the southern parts of the United States where you might get large Roman-style or perhaps Jacuzzi tubs, and also where you generally have far more intensive water utilization requirements.

If you live in an area such as these mentioned above, or you need a device that can save you on energy costs when it comes to heating water in your house, cottage or lodge, and you generally have more demanding water usage requirements, the Ecosmart ECO 27 KW Electric Tankless Water Heater should be able to do the job for you. This device is actually capable of heating approximately three gallons of water per minute at a temperature of 37 degrees Fahrenheit.

Other types of applications for the Ecosmart ECO 27 include the following: remote barbecue areas, pool houses, pool showers, remote bathrooms, hot tubs, or even to function as a booster, doing away with long hot water pipe runs.

Energy Savings with the Patented Self Modulating Technology

As well as a low upfront cost, energy savings are the Ecosmart ECO…

Bosch 2700ES NG Aquastar Indoor Tankless Natural Gas Water Heater Review

Bosch have a reputation for quality goods. And that’s usually shown in a slightly more expensive price. So is the extra worth it in this case? Let’s open up the Bosch 2700ES NG Aquastar 7.2 GPM tankless water heater and see for ourselves exactly how competent this system really is.

Bosch claims that their 2700ES NG Aquastar Indoor tankless natural gas water heater can deliver 7.2 gallons per minute, and can also supply hot water to 2 or 3 major appliances at the same time. At size, it is about the standard for the industry at 30 ½ inches high x 17.875 inches wide and 11 ¾ inches deep. But one thing it does supply that is nicer than most tankless systems is a very low minimum 0.65 gallons per minute to initiate heating. This means that if all you need is a very small flow for a job smaller than taking a shower, you still get hot water.

And the fact that this is an indoor rated unit means it is perfect in cold weather climates where outdoor units freeze in extremely low temps. The Bosch 2700ES NG Aquastar also earns you a $300 Federal Tax Credit, so factor that into the low price and you are already making money. You can also expect to save 25% to even 50% in some cases if you are replacing an electric tank system. That means this unit is paying itself off in around 2 or 3 years.

And running 2 or 3 hot water-using appliances at once without getting that hated “cold shower” effect is a cinch. At 19,000 BTU the instant heat is as hot as you want it, and regulating it is possible at the control box, or with the optional Remote Thermostat (Bosch TSTAT2). I recommend the thermostat for ease of use. Just mount it in your main bathroom and you have hands on manipulation electric units don’t offer.

The unit has a flat white color, and is very unobtrusive in a pantry, or bathroom closet. There is a 12 year warranty on the heat exchanger, and a full 2…
