SOURCE: Tankless Paloma NG hot water heater shuts down

have you checked the error codes on the heater?
you can do this by powering off the controler and pressing the up and down keys for a few seconds. this should take you into the diagnostics mode scroll using the up and down keys till you find the one that has the letter E on it and that will give you the last 8 error codes write them down and get back to me

SOURCE: ECO failure. Replaced the gas control thermostat & vapor sensor

It sounds like your gas/air mixture needs to be adjusted. The flame should have just the slightest amount of white, at the very tip. The rest should be evenly blue. There is an air vent adjustment in the line to the burner, right after the gas input.

SOURCE: Error code 13 (air flow) tankless H20 Rheem

Have 2 of these Rheem units in my house. Both had this same error code within 30 days of each other. And my neighbor has 2 units as well - and guess what - 2 months after mine stopped working because of the code - so did theirs. It is not something that can be fixed. It is a manufacturer's defect - and it looks like Rheem has yet another class action on their hands (like the one for the RTG - 74 PVN). They need to do a recall to repace these units.

My water heater shuts down in cold weather. How do I fix this problem


Add tempering tank.
Tempering tank made from old tank-type water heater, or small tank heater will passively heat incoming water.
http://waterheatertimer.org/Tempering-tank.html

This works because tankless can only raise temperature so many degrees. If water is very cold, tankless cannot keep up, so the sensors shut down the unit.
Passively preheating water... or using a small tank connected to power can preheat water enough so tankless works.
Also delime tankless each year will help remove natural scale that builds up inside tankless heat exchanger.

Look at front of water heater with cover open. Black rectangular piece of foam under pressure relief valve area, has "therm" and "eco" marked in white letters. Each has 2 male spade connectors sticking out. That is your Thermostat and eco ( emergency cut off) . The ECO basically is a safeguard in case thermostat malfunctions. It is set to shut water heater down, a few degrees hotter than thermostat, just in case. Peel the foam back to expose the Thermostat & ECO, and remove circular retainer to remove either.

After hot water demand, burner stays lit, blew up Pex supply line


Thermocouple has 2 ends. One end attaches to gas control valve, other end sits inside the pilot flame.
Flame heats thermocouple, causing tiny electrical current that is detected inside the gas control valve and keeps the gas valve open so water heater can turn on when thermostat calls for heating.
If pilot goes out, then no electric current reaches gas control, and all gas to burner and pilot is shut off.

If pex line burst, that implies very high pressure, caused by closed system with check valve that stops expansion, or possible clog in the water line, or high local water pressure, or clogged factory-installed heat traps.
Put pressure gauge like BTG100 on the drain valve to check pressure, should not exceed 80psi, install pressure reducing valve on cold water line, install expansion tank on cold water line. Remove heat traps and install ordinary pex-lined di-electric nipples from hardware store.

If the water was super hot, then overheating could have caused the pipe explosion.
However the gas control thermostat is ECO protected, and if ECO (energy cut off) trips because of high heat detected inside the tank or combustion chamber, the gas control will trip off and no longer work, gas control needs to be replaced. Some newer electronic gas controls can be reset, but that type heater uses a thermopile instead of thermocouple.
Thermopile is basically a group of thermocouples, that product more electric current that is used to power electronics inside the gas control valve, which issues an error code on the gas control, and some day will send a text message each time out-of-range event occurs.

Time to call qualified service technician. And watch what that person does to learn about your water heater.
I assume you have Honeywell Icon gas valve. Honeywell makes different several model numbers.

Here is 'typical' Honeywell Icon gas valve service manual for Bradford White, that may or may not apply to your water heater. It shows testing for Icon and disassembly instructions, and error codes.
http://waterheatertimer.org/pdf/Bradford-white-service-manual-44943-D.pdf

Gas water heaters today require yearly service that includes cleaning burner parts and combustion chamber, checking vent and air intake, electrical connections, testing gas valve, checking gas pressure, bleeding air out of gas line, etc. These are things you can learn to do by reading service manual, and making sure you have a spare water heater around to connect real quick if experiment goes wrong.
If Icon gas valve is problem, that control is modular and can be replaced without draining tank.

What is the energy factor for the mod.82V80-2? I have two seperate 30amp circuits, one for the top element and one for the bottom element, if that changes anything.


http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619
http://globalimageserver.com/fetchDocument.aspx?id=052c9e32-ce37-48d7-8990-9e430f23fef3

82V80-2 Energy factor is .86 according to water heater industry self-regulated standards.

Rheem pdf says these water heaters are wired for non-simultaneous operation.
Except special order water heaters.
Non-simultaneous operation uses single 240V circuit as described below.
If your water heater is wired for simultaneous operation, and each element is on a separate circuit, that makes your water heater special order. I would guess the reason is for higher first-hour delivery, which implies rapid heating and would likely affect energy factor.
You might want to get serial number off model and call Rheem for specs on that special order.

Your water heater energy factor may be the same because 'energy efficiency is based on the amount of hot water produced per unit of fuel consumed over a typical day.' This means an aircraft carrier can be considered highly efficient despite overall cost. And naturally the guys making the aircraft carrier are also doing the rating.
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000

Non simultaneous operation means the upper thermostat controls heating functions.
240V goes to upper thermostat first.
When water inside tank is cold, thermostat reads temperature through tank wall.
Upper thermostat turns on upper element until top 2/3 of tank reaches thermostat set point.
Once set point is reached, upper thermostat turns off upper element and sends power to lower thermostat and lower element.
Lower thermostat reads temperature through tank wall, and turns on lower element until bottom 1/3 of tank reaches thermostat set point.
As water cools inside tank, lower thermostat is first to respond since hot water rises.
Lower thermostat turns on lower element until tank again reaches set point.
When hot water faucet is turned on, hot water exits top of tank.
At same time, cold water enters bottom of tank through the dip tube.
The heating cycle repeats.
At all times, the electricity flows through upper thermostat. And upper thermostat is powered by one 240V circuit.

With simultaneous operation, the upper and lower thermostats work in same manner.
Except thermostats are wired separately.
Lower thermostat does not wait for upper part of tank to be heated first.
Lower thermostat turns on whenever lower part of tank cools.
The advantage is more hot water available rapidly when demand is high. This is called first hour recovery.

One method for reducing electric consumption is to set lower thermostat so it only turns on during certain times of day. For example Whirlpool Energy Smart operates in this manner and shaves a few bucks off the bill each month. This says that simultaneous operation is not an energy saver, unless that circuit controlling lower thermostat is set on a timer.

There's a little device that is like a pressure switch that starts heating when is senses water flow. This is what happens when it starts to go bad. You will need to call out a professional and have it serviced and the part repaired or more probably, replaced.
