EcoSmart vs Rheem Water Heaters

Gas water heating is usually cheaper, but an electric tankless water heater is your choice if you don’t have proper gas supply lines or ventilation system, need a small, quick and durable unit in office suites and all other public buildings. In the United States, there are two leading electric water heater manufacturers: EcoSmart and Rheem and few less popular – Bosh, Stiebel (Germany), Camplux (China), and others.

EcoSmart ECO Electric Tankless Water Heaters

Lifetime Warranty, self-modulating technology – unit will adjust power to current water flow. Temperature control in digital 1-degree increments.
Stainless and copper components for high durability and efficiency, six models (8-36KW, 2-6 gallons per minute), 240 volts

Pros:

EcoSmart gives the most extensive warranty on the market: Residential Heaters ECO8–36, lifetime warranty on electronics, Exchangers, and elements.

EcoSmart also offers SmartBoost unit – a 7.2 kW electric heater ECOTB240 to be connected to a tank gas or electric water heater to increase hot water delivery. SmartBoost will increase the efficiency by 45%, so you’ll get more hot water (like with much larger tank) for the lower price and installation costs. The Ecosmart will adjust pressure settings and power usage to keep a consistent output for you.

Cons:

Warranty is eligible for tankless electric water heaters installed by licensed electrician/plumber within 30 days of purchase, warranty registration must be filled and post marked within 30 days of purchase. Be careful to register your unit properly.

Service wait times sometimes are long and warranty covers the parts only cost. Labor to repair might be expensive, and it is not a very complex device and you can often make simple repairs yourself if you are handy.

Conclusions:

Buying EcoSmart  Electric Water Heater is a good decision. The Ecosmarts is well-reviewed, reliable and efficient units. It is a great choice for most people – has a power range of 5.5 to 36KW that is suitable for appliances from hand washing to large family home in cold climate regions.

Rheem Tankless Electric Water Heater Characteristics

Energy efficient – 99.8%, digital temperature display. Industry leading low flow activation – unit start heating when the tap is turned on low.

Pros:

Rheem units are one of the most compact tankless water heaters, and it allows to install it right near the sink and minimize hot pipe losses. Besides, the Rheem units are cheap enough to allow energy savings pay off expenses in a reasonable time – in several years, one of the best turnover periods.

Cons:

Hard water ruins these units fast, so you should put a softener in line ahead of it or clean it annually. It is an important thing you have to factor in the cost of going tankless when your water is hard (see our maintenance manual).

Similar to Ecosmart, if the unit is not installed by professionals, it could get you into an issue upon returning the item.

Overall:

Rheem units have low flow activation, have nice displays, look great and are cheaper than Ecosmart. But warranty conditions are worse, reliability issues occur, and there are more assembly quality complaints. Nevertheless, Rheem is a great cost effective choice if you need a compact solution.

Tankless Water Heaters

The first experience I had with a tankless water heater was in Singapore, many, many years ago. There were three: One for each bedroom and one for the kitchen. Many things seemed strange to me since it was my first time out of the states, but these tankless water heaters were some of the strangest. They were not new by any means but they immediately supplied as much hot water as we needed whenever we needed it. They were not as small as the units made now, but they were a lot smaller than the hot water tanks we’d been used to.
Now, you can find tankless water heaters that are made powerful enough to heat an entire house instead of just one bathroom or the kitchen, so you only need one. The sizes run from small enough to install under the sink in an RV or large enough to heat water for a commercial operation. They’ve come a long way!

The only difference you’ll notice (besides having an endless supply of hot water) is that you will have to turn the water up to a certain flow before the heater will come on. If the heater is adjusted well and the filter is clean, you will hardly notice. With our three units, we had to turn the water up quite a bit before the heater would turn on. The technology for both gas and electric tankless heaters has progressed tremendously since those days in Singapore.

Tankless water heaters cost more to purchase than traditional tank heaters, but they will save money over time and are a good investment with utility prices going up and up everywhere. If you’re interested in buying one, be sure to look for the Energy Star label to save even more gas or electricity over the life of the heater, which, by the way, is much longer than a tank heater – twenty years, easily. That’s twice the life expectancy of a traditional tank heater. When you figure the length of use and the savings on gas or electricity, a tank heater can be quite a bit cheaper to operate and much more convenient. No more cold showers or waiting for the water to heat up again.

Another great advantage is the space saved. Tankless water heaters by definition take up less room than a tank and since they’re installed on the wall, they free up what little floor space they would take. That makes them an excellent choice for apartments, recreational vehicles and anywhere else space is needed.

Both electric and gas tankless water heaters are practically maintenance free other than cleaning a small filter occasionally. There is a downside to this though. You must be sure that the plumber chosen to install the tankless heater is familiar with them and knows how and where to put the filter as well as other minor differences.

A tankless water heater can replace all conventional heaters and work with solar and other alternative types to ensure that you always have enough hot water for anything you do.
