I convert from a natural gas tank water heater to a electric tankless water heater and then back again =(

I’ve had mine for 3 years and have had no problems. I did buy a critical spair just to have one on site, however I plan on not having to replace it for quite some time.

Good to hear from a long time owner, thanks for sharing.

I also looked at the same model, and the specs indicate that it can only raise the temperature from 31° to 92° depending on the water flow/gallons per minute. Figuring approximately 4.4 gallons per minute (GPM) for 2 showers shows that the temperature rise from the incoming temperature will be 46°f. If the incoming water is around 50°f, the output would be 96°f, most likely a little lower, using 4.4 GPM. But using 2.5 GPM, the same incoming water could reach approximately 124°f. In my area, the average tap temperature from the ground is 53°f. The RMTEX-27 max temperature increase using the 6 GMP flow would only increase by approximately 31°f. IE 84°f output at the tap. Our house has 3 adults, so we stagger our showers by 10 minutes, and all of us can have water temperatures over 120°f. Tankless really comes down to GPM and groundwater temperature.

Great summary, thanks for sharing.

Yeah, my guy didn't do enough research and didn't understand the water temperature capabilities of the unit he bought.

I’ve heard if you lower your water flow it will heat up much better. May also need a booster unit if your showers are far away.

Agree, they do recommend flow restrictors at the outlet of the unit but I don't think that's practical to limit water flow that much for running two showers at once.

We focus on Electric tankless water heaters and are looking for testers to shoot videos. We look forward to collaborating with you and hearing back from you.

Hmm. I just put in the 27 kWh unit in Upstate SC and seems to work just fine thus far. It is just my wife and I though and incoming water is warmer than northern us. They have a chart for the regions and what size would be necessary.

@TheLawnEngineer 4 ай бұрын

I’m in Wisconsin, so we probably have a significant difference in incoming water temperature. The chart told me this unit was good for two simultaneous showers in my area.

I'm looking at doing a tankless electric in SC also. Do you find your tankless electric allows simultaneous showering for you guys in winter? Are you able to have at least one person able to take really long showers? Thanks for any insight.

I isolation valves? No T&P valve?

@TheLawnEngineer 2 ай бұрын

I’ve found PEX so easy to work with, I don’t mind just using the main water shutoff to service things. However, I would never discourage anyone from adding valves.

@drivebysnapshots 2 ай бұрын

@@TheLawnEngineer by code you need a T&P valve. How are you going to relieve pressure if the water heater fails to turn off and thermal expansion starts to occur? Also How are you going to flush your water heater without isolation valves?

Wow, what a bummer discovering that problem about a lukewarm water delivery. I was kinda expecting you say 'if you like cold showers then this is the unit for you.' The house I bought has a tankless water heater, but it's done with propane (which also heats the radiant heat stuff in the concrete slab). But as it's just me, I don't know if the previous owners had problems with simultaneous showers. So, do we get a video of you installing the new tank unit?

@TheLawnEngineer 7 ай бұрын

Yes it was a bummer. I was pretty fed up and didn’t film much of the tank heater install 🙃. I did video cutting apart the old unit to see what condition the tank was in…that’s pretty interesting.
