Rheem RTEX 08 Review

Overview

Rheem RTEX 08 is an excellent unit for being sued as a point-of-use application and for obtaining hot water whenever required. It is a very compact, light-weight and efficient water heater that can potentially lower your regular energy bills to great extent. It is one of the leading electric water heating units and no other model offers such a wide array of useful features like it does. Here are some of its prominent features:
  • On-Unit control of temperature
  • LED equipped with standby mode and active element
  • 1/2inch water connection
  • Reliable heat exchanger created from brass/copper
  • Power modulating
Just like the case with all Rheem tankless heaters, RTE 9 also doesn’t require T&P valve. Its compact size makes it suitable for all sorts of locations such as condos, hospitals, homes, apartments and offices. It offers a 30degree F temperature rise and you can expect around 5GPM hot water.

The Pros & Cons of the Rheem RTEX 08

Pros

  • Compact size and light weight saves storage space
  • Excellent as point-of-use application
  • Easy to mount and simplistic water connections through 1/2inch compression fittings
  • circle
    Modulating heat exchanger makes the unit energy efficient
  • circle
    Saves energy through the standby mode

Cons

  • Not suitable for large families
  • Unit loses efficiency if used by many people
  • Installation although is simple but requires additional wiring and pole breakers, which increases installation cost

Installation and Specifications

The unit’s Use & Care Manual comprehensively informs about the installation procedure. It gets installed fairly easily and quickly. Just mount the heater and an electrical junction box to the area you need to fit it. Plumb the unit into water pipe using the PTC (push to connect) pipe fittings. Flip-off the main breaker and run the 8-gauge wire between the RTE9 and circuit breaker panel and tie it into the junction box using wire-nuts. Lastly, connect the wire to 240V/40amp breaker.

Common Problems

The unit is although being promoted as suitable for large families but in reality it can support no more than two persons at a time. You cannot perform multiple tasks simultaneously such as washing dishes and taking bath, which makes it not suitable for families that demand hot water very frequently. Conversely, response time is very quick and way faster than a gas tankless water heater since a gas unit takes at least 30sec to start warming water whereas RTE9 takes just 15sec. It is an ideal point-of-use application for small family and must be bought if you want to replace gas water heater with an energy efficient electric one.

Conclusion

Definitely go out and get a Rheem RTE 9 electric tankless heater if you live alone and have limited storage space at home. The heater will suffice for your use only and may also support one more person’s needs, but not at the same time. Installation is fairly simple but will cost a little for wiring and pole breakers. If you want to replace your old heater with a new one without too much demand on hot water supply then opt for this one.

Stiebel Eltron Tempra 29 Plus Review

Overview

Stiebel Eltron Tempra 29 Plus is one of the most technologically advanced and reliable Tankless Water Heaters currently available in the market. Stiebel has redesigned its Tempra series units and the new Tempra Plus range of water heaters have advanced Flow Control system, heavy-duty electronics, hinged cover and simplistic single flow sensor design.  In comparison to other gas tankless models the Tempra plus range is very affordable, energy efficient and long lasting. Installation is fairly simple and user friendly since venting is not required. This heater has a digital temperature display and easy-to-use dial selector through which you can set your desired output water temperature between 86 and 125F/30 and 52C. The best feature of Tempra 29 Plus is that it automatically senses and adjusts water flow rate as well as its temperature and calculates the amount of power required to heat the water. This is how it applies exactly as much power as is needed to maintain the demanded output temperature despite the changes in flow rate. We recommend that you get it installed by a professional.

  • Requires 50amp circuit breakers and 8gauge copper wiring
  • 99% energy efficiency and 15-20 percent savings
  • ETL listed for abiding with CSA and UL safety standards in the United States and Canada
  • Excused from Seismic Code
  • Contains thermal and overheat safety protection
  • Three year residential and commercial warranty under normal use
  • Advanced flow control feature allows automatic flow reduction in delivering water if demand exceeds capacity

The Pros & Cons of the Stiebel Eltron Tempra 29 Plus

Pros

  • This is comparatively a better choice than tank-type water heater models especially in hard water areas because you can set it on low temperature for minimizing scale formation
  • Space saving and stylish design immediately fits into any given area
  • Digital thermostat keeps water to the exact same temperature as you set
  • circle

  • circle
    User manual is very helpful and explanatory
  • circle
    Easy to install unit without requiring expensive mixing of valves or additional temperature regulators
  • circle
    No need to drain and clean your storage tank every year and replace anode rods because it heats water directly and thus, there is no storage tank

Cons

  • The unit needs dedicated water line
  • Some users complain that while the heater is in use a number of other appliances like bulbs or fluorescent fixtures start flickering
  • Installation is although easy but a bit expensive because you will need a new electrical box, 8gauge wire and 3x50amp breakers. Plus, a professional electrician only can install it

Installation and Specifications

You need to install Tempra 29 Plus unit vertically in a way that the water fittings point downwards. Installation is pretty straightforward. All you need to do is arrange three 208-240V lines, that is, six spaces in your breaker panel and 8gauge copper wiring. For plumbing you may choose between CPVC and Copper. If you use copper then we would recommend using sharkbite / gatorbite fittings. The heater has five mounting points so that you could easily mount it on the watt. You may easily mount it on the wall with drywall anchors.

Common Problems

Never use substandard wiring while installing this unit and always use those recommended by the maker.

Moreover, never install the heater yourself and ask for professional help.  Use detachable water connections like the braided steel flex connectors for ensuring periodic filter cleaning especially flushing away scale if there is hard water. If you aren’t certain about the electrical capacity within your household then consult an electrician before purchasing the product.

Conclusion

Tempra® Plus is a very reliable, affordable and easy-to-use tankless water heater. It is equipped with the Advanced Flow Control technology that ensures the water temperature remains constant no matter how much the demand exceeds. This means you will receive a satisfying supply of hot water as per your requirement without the fear of cold water splashes while bathing or dishwashing. For this price tag it is the best choice in the currently available water heaters.

It utilizes less energy but offers maximum flow rate therefore, it is highly feasible if you want to save money and electricity both. The product utilizes around 50% less power than regular storage type heaters.

The Pros & Cons of the Stiebel Eltron DHC 6-2

Pros

  • It heats water when you demand it and doesn’t store water
  • It utilizes approximately half the amount of energy that a conventional tanked heater would use because it doesn’t involve constant supply of gas or electricity for maintaining its water reserve temperature
  • It is much more safe and reliable option than tanked heaters because it is equipped with a built-in thermostat that can detect overheating incidence and will stop operating immediately

Cons

  • It cannot maintain high water temperature and this becomes very irritating when you need very hot water
  • The efficiency of this unit can be affected substantially if more than one water outlets are in use because the unit only offers limited amount of hot water

Installation and Specifications

DHC 62 is a point-of-use device and can be installed conveniently at a variety of areas like kitchens, bathrooms, restrooms, restaurants and even at schools, malls, gas stations and farm houses. Installation wise it is very simple and the unit comes with a thorough installation guide. However, we suggest that you hire licensed electricians and plumbers to ensure a job well done. You need to hardwire this product to a designated 30A circuit with 2 live wirings for getting the required 240V. The unit doesn’t come with any plug or electrical cord and you have to plan ahead before buying it and have a circuit available nearby where you need to install it. The unit requires 1/2inch NPT water connections.

This means this heater is perfect for being used at southern regions. Moreover, for a small flat and a family of 2 to 3 people this unit is ideal but for medium to large families, this is not a feasible choice of heater.

Conclusion

Overall, the Stiebel Eltron DHC 6-2 is an excellent water heater, one without many flaws, and the great features it does possess outweigh the minor flaws in its operation.

Installation and Specifications

You can install it yourself easily just like any tankless water heater. Since the unit is extremely compact therefore, you need not to worry about the space. It is ideal for small homes, condos, kitchens and offices. The user manual included in the package informs comprehensively about the process of installation. However, you may require additional wiring and piping especially if the wires that you currently have are plastic ones. Always use copper pipes for connecting water supply with this unit. You may require 80ft wiring for the unit’s two separate circuits. Remember to keep the two hot leads of every circuit away from each other and every double-pole circuit’s hot leads have to be paired up. For plumbing purposes use flexible water heater connectors of braided material and then connect them to CPVC. You will need at least 150amp electrical panel with two 40amp double pole-breakers linked to two sets of 8-gauge wire.

Common Problems

If you haven’t sized it properly then water supply will be limited and also in extremely cold regions the performance of the unit may get affected. Therefore before purchasing you need to select the right size by evaluating the size of family, expected hot water demand and electrical requirements. Technology-wise this heater is ideal choice but the installation cost may exceed your budget because the 2x40amp double pole breakers, 150amp electrical panel and a pair of 8awg wiring doesn’t come cheap.

Conclusion

In terms of its technology, it is a great choice for a water heater but installation can be quite costly as it requires a minimum 150 amp electrical panel with 2 x 40 amp double pole breakers connected to 2 set of 8 awg wire and that doesn’t come cheap as it also depends on how far you want your wiring to go. 3/4” NPT plumbing connections are also needed.

Common Problems

As is the case with all tankless water heaters, ECO11 also offers fluctuations in flow rate and temperatures. Therefore, if it is used in very cold weather where temperature is set at the highest then water turnover will be limited in terms of gallons per minute in comparison to the efficiency it offers in warmer weather conditions. However, if you have sized it appropriately then you can enjoy endless hot water supply without worrying about high energy consumption. You need to evaluate the right size of this heater before making the purchase considering your electrical requirements and frequency of hot water demand as well as family size.

Conclusion

This is a good buy for a single person living alone and even for a student with a one-bathroom apartment. It does not work efficiently for families who need more hot water flow in their homes. If used properly, it can save up to 60% on your energy bill. Also, considering its compact size, it can save you up to 12 cubic feet of space.
