Question about Bosch & Tankless LP Hot Water Heater

3 Answers

I unfortunately own a Omega 2000 Group tankless

I unfortunately own an Omega 2000 Group Tankless water heater. It did not come with an owner’s manual and after requesting it and never getting any response; I don't know what else to do. I have the OME 620 D model; it sporadically will give an E2 error which on their list says incomplete burn. I don't know how to fix that problem. Any ideas?

E2 is the overtemp code. Unfortunately, the Omega line does poorly with single-handle faucets. Don't bother George Sararu, he just bought a container of these water heaters and knows nothing about plumbing. There will be no repair parts you will need. Either toss it now and get a tankless from a local dealer, or wait until your Omega unit is totally useless, then go with a local guy. George conned a lot of people - including me. I own 2 side-by-side in the utility room and figure one more year until they are junk.
Since I'm on a well, they have to be seasonally adjusted to compensate for groundwater temps. Big pain, should have bought Rinnai.

The owner is not clear about the gas used so:
If this is a LPG then the pressure regulator is delivering too small amount (below 144.000 BTU) or gas connection is too small (that goes for NG also!) That condition creates a flame-out so you get E2 from ION sensor. Reducing the speed of the fan will resolve the problem if previous issues are too costly or impossible to fix. That is done from the control panel on test mode.

Rheem pronto tankless water heater just barely warm model # 74pvn-1. This is in a house we are just purchasing. Also it looks like it may be attatched to another tank water heater , Help please


Before calling service technician, open following link for Rheem troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Sometimes people attach tankless to tank-type heater to preheat incoming cold water.
Additional tanks are also used to store solar heat, and some installations have tank-type because tankless is unreliable. Service technician can sort out the function correctly.
http://waterheatertimer.org/Tempering-tank.html

Owner should read tankless manual thoroughly, especially troubleshoot and maintenance sections. Tankless require yearly maintenance.

Since tankless are expensive to repair and replace, you might be able to fire up the tank-type water heater and provide hot water without much cost.
You can also install tank-type gas water heater yourself. Lowes sells 40 gallon for $317.00, and then you offer 10% less.

I have a Rheem EcoSense tankless water heater that I want to set the temp to 140degF. How do I set it internally for this?


1) The best place to find this information in your manual.
Typical Rheem manual in my files shows temperature is adjusted by pressing UP and DOWN temperature buttons on remote.

2) Manual says: Temperatures of up to 140°F
(60°C) for Light duty models and up to 180°F
(82°C) for Heavy Duty models can be
achieved with the MAIN (UMC-117) remote
control and a dip switch adjustment. Only
qualified service personnel should perform
this adjustment. Only factory authorized
remote control(s) should be used.

3) Typical manual shows information on page 22-23. Search pdf for 'temp'
http://waterheatertimer.org/pdf/Rheem-RTG74IndoorOutdoor_owners.pdf

4) This information squares with what I heard before that trained service technician is needed to adjust water temperature.
I think Rheem does this since tankless will not achieve that rise in temperature if incoming water is cold.
BTUs put out by tankless burner has limit.
If incoming water is colder than certain temperature, then tankless cannot raise temperature quick enough as water passes through burner.

5) You might also need a tempering tank, to modify cold water in winter:
http://waterheatertimer.org/Tempering-tank.html

6) Suggest you also read the yearly maintenance required for tankless.
For example tankless are prone to lime build up and need to be de-limed each year with vinegar.
Lime build up will certainly affect water temperature.

7) Following 2 links might be helpful for tankless owner:

Tankless water heater water will not come out hot enough


1) Read your manual

2) De-lime unit on yearly basis:
Search google and Utube for 'de-lime tankless'
They make special fittings that permanently attach to water ports so you can delime each year.
Research shows that reqular de-liming will not restore tankless efficiency.
http://waterheatertimer.org/pdf/Delime-tankless-water-heater.pdf

3) Typical manual shows temp information on page 22-23. Search pdf for 'temp'
http://waterheatertimer.org/pdf/Rheem-RTG74IndoorOutdoor_owners.pdf


4) Read maintenance steps shown in manual
The word maintenance appears throughout the manual

5) Search fixya questions on tankless to glean information about your unit:
Older answers have more responses, and each seems varied as techniques succeed for one person but not another.
The quantity of unanswered questions and vague answers reveals why Rheem suggests qualified technician be added to your rolodex-wallet
