Question about Noritz 7.1 Gpm Propane Lp Gas Tankless Hot Water Heater

1 Answer

Sluggish gas value in tankless propane water heater

I have a 5 year old inexpensive Chinese tankless propane water heater - brand name "Powtek". Problem: the gas value is sticking. If I rap on it, it starts. How do I service the gas valve and what lubricant is OK? I have a teflon lube called Tri Flow. I live in rural Panama, so normal solutions are hard to find.
Thanks -

    I was also told by a neighbor that these heaters are very sensitive to the condition of the two D cell batteries that provide the ignition spark. They can be producing a fine spark, but unless they are close to brand new, they don't have enough kick to activate the gas valve.
    I tested my batteries with a Radio Shack tester, and they were 1.36 volts. They had been providing a good spark. I put in new batteries and they read 1.59 volts. The heater worked perfectly with the new batteries. So, my neighbor was right.

Can you convert the tankless water heater model # RL94in from natural gas to propane?


Contact Rinna
Some water heaters allows changeover by installing new chipboard or changing dip switches... some do not.
Propane burns much hotter with higher pressure than natural gas

The heater does not shut off when the faucets are turned off. It is intermittent and after turning the faucet on and off a few times it will eventually shut off. What the solution to fix this problem?


First, add a comment and describe which heater you have: tankless, tank, gas, electric, which brand, approximate age of installation, and what you have done so far.

Next would be to turn off all taps, and put ear on pipe and listen for water leak.

If cold water is running and hot is off, and single-handled faucet has crossover problem, then a water heater will continue to receive incoming water causing waste of energy
http://waterheatertimer.org/Crossover.html

Next would be to review product manual for troubleshoot, and required maintenance.
Next would be to call installer, if installation is new.
Next would be to call manufacturer and ask for name of qualified service technician in area, and check if your product is still under warranty.

If you have tankless computer water heater, and unit is older than 5 years, then imagine how well your 5 year old laptop computer works, and then install tank-type heater to avoid continual maintenance and failures:

My Jacuzzi J-N180F tankless water heater will not even light.


Access your product manual.
I cannot find a product manual.
Some major company, like Rheem, makes this computer that heats water.

Call service technician to repair the unit.
Copy following link for overview of type of problems found with tankless computers.
For example tankless computers require continual maintenance on yearly and monthly basis to prolong expected life of product.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

If tankless computer is older than 5 years, then assume it is like your 5-year old laptop computer.

Save problems, and repair the unit yourself, same day, by installing tank-type water heater:

Moved into a house with an existing Rinnai system. We have controllers in the kitchen and bathrooms. My understanding was that you can change the temp by hitting the priority button then up or down as long...


You need a product manual for your tankless computer that heats water.
Look on side of unit for label.
Then google that brand and model and add .pdf to search parameter to find possible resources.
Or try Rinnai website for a dose of promotion about how great their product is.
If unit is a few years old (age of unit accessed with serial number), there might be no manuals posted online since manufacturers often drop manuals from website after a few years, assuming most their products no longer function correctly and thus avoid available knowledge for customer to talk specifics... instead telling customer to call service tech who of course does not have manual either because he is a tech and needs one, but got hired last week to his new esteemed position and gets paid by service call not by successful repair except bonuses for recommending replacement unit.

Read the manual. Especially required maintenance, such as deliming yearly and cleaning water filter.
Note resources for maintaining tankless appear on following link except for different brand tankless computer:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime

Also scroll down page to read explanation of high temperature limit for tankless before causing irreversible problem with your computer requiring skilled technician.
Also scroll up on page to read about no error code, since cooler than normal temperatures from tankless computer can be result of common plumbing problems like defective single-handle faucet cartridge. Or power surge, since tankless are not protected from ordinary surge event like power restored after outage.

If your tankless computer is older than 5 years, then assume it will not work better than your 5-year old cell phone or 5-year old laptop, or behave better than 5 year old child. So don't assume you are doing something wrong... just assume it doesn't work despite glossy advertising brochures from tankless manufacturers claiming 20 year lifespan for tankless computers.

Install tank type heater yourself, same day and avoid computer water heaters: Ordinary plumber can fix these units easy.

Bosch 125fx heater barely heats water


1) Recommend replacing tankless with ordinary tank-type gas water heater.
http://waterheatertimer.org/How-to-install-gas-water-heater.html
http://hometips.me/Mar/Which-is-best-gas-water-heater.pdf

2) Tankless cannot be exposed to more than 11 grains hardness in water or unit will fail within 2-5 years. Water softener is required.
http://hometips.me/Tls/Battelle_Water-softening-research.pdf

3) Descaling tankless water heater each year will not restore functionality, or restore efficiency of tankless, nor restore full efficiency to tank-type gas water heater.

4) Bradford White side-by-side testing research comparing their tankless with their tank-type shows that tankless will save $1-8 per month on energy bill vrs ordianry tank-type ....but conclude that tankless 'fall far short of payback' due to maintenance, repair, installation and replacement costs.
Study compared full cost, and not just monthly energy bill, since All costs are energy.

I have a Bosch GWH 425 HNO propane Tankless Water Heater which began intermittently exploding when demand for hot water occurs.


Call a qualified service tech immediately.
Gas explosion indicates dirty combustion parts, and gas is not fully igniting when tankless turns on the gas. So gas builds up and then explodes causing serious damage to tankless, and serious risk to homeowner.

My Rheem tankless water heater has been flashing a C8 and 76 code. I can turn off the heater using the power button on the unit, but my hot water will only last for a shower or so. Any suggestions? ...


Before calling service technician, open following link for troubleshoot resources including Rheem chat and contact, possible manual, error codes, etc.:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

C8 76 is generally bad PC board. Call 800-432-8373
Just like a motherboard on your computer, the tankless PC board is operational center of tankless water heater.
Various sensors gather information from water pipes, gas line, vent pipe, and air supply to determine when to activate burner.
Most people understand that when their computer motherboard needs replacement, that computer will probably not work reliably again.

Tankless is basically connecting a complex computer to your plumbing and electrical lines and to a gas burner with a vent pipe to outdoors, despite knowing that plumbing lines, vent pipes, gas burners, and household electrical systems have plenty of problems on their own.

Age factor: When tankless is new and everything operates perfectly, the tankless works correctly.
And each tankless manual recommends yearly and monthly maintenance, just to maintain operation, the cost of which can exceed the expected 1-8$ monthly savings. And who wants to clean the water filter each month and delime the exchanger every year?
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Don't buy a tankless water heater because the only folks promising unlimited hot water and effortless water heating experience while saving money with a tankless are the tankless promotors.

Solve most tankless problems yourself, same day, any brand for about $350.
