EcoSmart is a well-known brand of tankless electric water heaters, and the ECO 27 is well-equipped to meet your home's hot water demands. This bigger model has flow rates ranging from 2.7 to 6.5 GPM, depending on the temperature of the entering water. To put this in perspective, it's normally enough to run a shower and a sink at the same time, but residences in warmer climates can have numerous showers and sinks running at the same time.

You may set the temperature in 1-degree increments from 80 to 140 degrees Fahrenheit using a computerized control panel. This allows you to tailor the temperature of the water to your specific requirements. The small ECO 27, which measures 17 × 17 inches, hangs on the wall in your basement or utility closet, freeing up floor room for cleaning supplies or other storage needs. Tankless water heaters are popular for a variety of reasons, including energy efficiency and space savings.

+Compact size

The A.O Smith Signature Gas Water Heater is the cheapest big water heater in our selection, but that doesn't mean you'll be disappointed. Sure, it lacks some of the more advanced features found in other models, but for the price, this water heater is enough for heating enough water for a household. The features that it does have been thoroughly thought out.
The push-button ignition simplifies the starter process, and the LED status indicator keeps you informed if anything goes wrong. While the guarantee on this water heater is just six years, it is one of the shortest of all the models we tested, and the price is one of the lowest, making the shorter warranty seem reasonable. A.O Smith is a well-known brand that provides a solid and dependable water heater at a reasonable price.

Pros:
+Good value
+Great for families
+Ceramic tank

Cons:
-Shorter warranty
-Has anode rods that are prone to corrosion

Natural gas water heaters are a cost-effective solution to ensure that you have a constant supply of hot water for your home. The Rheem Performance Power Vent series, which comes in tank capacities ranging from 40 to 75 gallons, is a popular choice for a tank-style gas water heater.

The advantage of this gas water heater is its flexibility to vent to the exterior either horizontally or vertically—up to 100 feet—thanks to its fan-propelled exhaust system. This opens up more installation options and allows you to move your gas water heater more conveniently. Furthermore, rather than using ambient air for system functions, the water heater draws air in from the outside. The model's energy efficiency has been enhanced, and it now has a consistent energy factor of 0.69, making it Energy Star compliant.

The tank of this model is walled with glass, and an anode rod protects it from corrosion caused by hard minerals in your water supply. The tank and parts are covered by a 6-year limited guarantee, however, in-home labour is only covered for one year.

Pros:
+Vents horizontally or vertically up to 100 feet
+Draws air from the outside
+Easy to relocate
+Energy Star qualified

Cons:
- Uses quite a lot of space
-Only a one year warranty on in-home labor

Detail information:

• Brand: Rheem
• Item Dimensions: 21 x 21 x 65 inches
• Item Weight: 159.7 pounds
