Question about Heating & Cooling

1 Answer

I am having a problem with my Rinnai Tankless Water Heater R94LSi. It says "120" on the thermostat. When I turn on the water and run it for 30 seconds or so, the readout turns to "60" and it starts to beep. The water does not heat up at all and I can't hear the usual whirring sound it makes. This happened about a month ago and then fixed itself within 24 hours. The technician could not find any problems or error codes. Ideas?

    I have the owner's manual. Are you trying to point me to a specific page in there? What do you mean "connections on the the heater that could be loose." Can you please be more specific?

Hi med2e,

I see that you already had a tech come out and check the Heater for you and no problems were found, you also mentioned that in 24 hours the system just fixed itself.

Regarding your question about any Ideas I believe that you can try to check for any connections on the heater that could be lose which could be a possible reason why it is giving you a different reading then when in use it gives out a different thermostat.

you can check at this link for further details on what can cause the issue you are experiencing, see link below.

Rinnai tankless hot water heater


Try replacement valve or solinoid for it on Ebay, or MFG website, or their customer service web site. They may not help due to critical safety issues with DIY fixes.

Rinnai Trouble Shooting


Clean water filter.
Delime heat exchanger.

Don't install multi-sensor computer-chip water heater to water lines and gas line and vent pipe since tankless will develop unsolvable problems.
Contact Rinnai and hear them tell you to call service technician, only to discover there are no qualified service technicians in your area who might be able to solve problem. 1-800-621-9419
Ask why the Rainnai site has much promotional information and no service manuals. Nor does Rinnai offer forum where tankless owners can freely exchange their endless unsolvable problems for all to see.

Im looking for the best option to get a Rinnai unit that would supply water at 30c or just below. i was going to buy the REU 55RT but looking at the manual i dont know how low the temp can get


Most tankless are preset to 120 degrees F.
30 degrees C is 86 degrees F.

If you want adjustable product, then tankless is not best choice.
Tankless are high tech gadgets with multiple interrelated parts controlled by sensors feeding information to control board. Everything internal and external has to be working correctly for tankless to work at all.
Most tankless brands do not suggest self-install, or self-adjustment, or any adjustment for reason given above.
You would be better off buying typical tank-type gas or electric and then thermostat adjustment is simple.

Rinnai Tankless won't stay on


how far is the tankless from the gas meter? error code 12 means it doesn't have enough gas running to it. is the 3/4 flex true 3/4 or is it 1/2 with 3/4 threads. have you checked your BTU load on your house to make sure your 1'' pipe can handle everything else you have on the house? sounds like to me you dont have the right amount of gas to the unit.
