Rheem RTE 13 4 GPM Tankless Electric Water Heater Review

April 14, 2012 | Comments: 0 | Views: 316

The Rheem RTE 13 4 GPM Tankless Electric Water Heater is the ideal hot water heater for low use requirements. Perfectly able to handle a single point of use at a time, this water heater will deliver 4 gallons of hot water per minute to your shower, kitchen sink, workshop, boat or wherever you need instant hot water.

The Rheem RTE 13 4 GPM Tankless Electric Water Heater is an indoor electric hot water heater. For optimum benefit, install the unit as close as possible to the point of use, i.e., under the sink or next to the shower stall because water cools the further it has to travel from the heat source.

At 4 gallons per minute this water heater delivers over the average requirements; enjoy a hot shower in comfort knowing that there is enough water to remove even the worst dirt and grime after a day's work. See the typical flow rates below:

Application Flow Rate in GPM at 60 PSI

Typical Shower 2.0 GPM

Typical Bath Tub Faucet 2.5 GPM

Bathroom Vanity Sink Faucet 1.0 GPM

Kitchen Sink Faucet 1.5 GPM

Washing Machine 2.0 GPM

Setting The Water Temperature

It is important to understand how the temperature settings on your water heater work. The actual thermostat is factory set at the lowest setting and the temperature ranges within that setting are controlled by the user via the control knob. Setting the thermostat at the lowest temperature setting is a safety feature and helps to ensure that children, the disabled, and the elderly do not unknowingly scald themselves when switching on the hot water.

Additional benefits to keeping a low thermostat temperature are the lower costs of energy to heat the water, and, less water is wasted as you don't need to add cold water to reduce scalding. Think Energy Efficiency!

Temperature Time To Produce a Serious Burn

120°F More than 5 minutes

125°F 11/2 to 2 minutes

130°F About 30 seconds

135°F About 10 seconds

140°F Less than 5 seconds

145°F Less than 3 seconds

150°F About 11/2 seconds

155°F About 1 second

Customer Feedback

If you are used to conducting research before you buy a product, you will know that frequently one customer can rave over a product and say it is the best thing since sliced bread, while another will rant about the same product and say it doesn't work. That's why it's always important to get a good grasp of what your own requirements are, and, if the product can meet those needs.

Many users are thrilled with their Rheem RTE 13 4 GPM Tankless Electric Water Heater and use it for deer lots, small washing machines, showers, and the kitchen sink. The water flow meets their expectations and the water temperature is continuously hot.

Some users report low water temperatures and faulty units; this is inevitable with any water tank, if the tank is located away from the point of use and if the delivering water lines don't have enough pressure there will be problems maintaining consistent temperature.

If the hot water tank is upstairs in one of the bathrooms you may need to run the tap for several minutes in the basement suite before you get the hottest water. A lot of water is wasted while you run the taps and that's why tankless hot water heaters save you money.

Installing the Rheem RTE 13 4 GPM Tankless Electric Water Heater under the sink in the basement suite ensures you have hot water when you turn on the tap; not cold water washed down the drain as you wait for hot water. Save money on your water bill and your electricity bill by only using the water, and the hot water, that you need.

Finally, make sure you know the average ground temperature in your area and get the Rheem Tankless Hot Water Heater to meet your conditions.
