SOURCE: thinking of putting a tankless water heater in

As a precaution, you should check with the manufacturer for the required gas volume and pressure requirements needed to properly supply the unit, and that will help to determine the pipe size and configuration.

In mast cases you'll find that If you are installing the tankless unit at or very near the location of the existing W/H then there should be no reason to change the pipe diameter from the 1/2" feed that is already in use to the existing W/H.

My view is, the current configuration that supplies a 50 gal. W/H should deliver ample volume and pressure to the new tankless unit.

If the tankless unit is to be installed at a different location then the existing W/H then the general rule of thumb is,
3/4-inch black iron pipe can be run up to about 20 feet of length from the gas meter or regulator, and 1-inch black iron pipe can be run for distances up to 70 feet. If other gas appliances are also in the home (gas range, gas clothes dryer and furnace, for examples), larger diameter gas piping may be required to run all appliances at the same time. Keep in mind that in new construction this is easy to plan, but in a remodel, adding larger gas line piping can add to costs of time and materials. Additionally, elevations more than 4,000 feet above sea level may require adjustments for the unit to run properly.

Note: Check with your local plumbing code for your areas requirements.

Good luck

did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

SOURCE: My Paloma tankless water heater flashes C2 11 error code

I just had the same problem and I fixed it in about an hour or 2. First shut off the gas,water and power(unplug it) Take off the cover There are about 20 screws above the electrical circuit board. You have to remove all of those screws to remove plate that is covering the burner assembly. The burner assembly has these 3 pins that look like number 7's these are covered with build up and gas can't flow right. That's why you get the c211 error not enough gas. Take a wire brush and gently remove any build up, I also cleaned the thermocoupler which is next to the burners. It looks like a metal pin with a couple of wires coming out of it this was also very dirty. I took a can of air and basically freshened it up It works perfect now. Email me with any Q's at Mario@myredr.com Good Luck All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

SOURCE: Paloma tankless, gas, water heater, error code C7 76

If you look on the left hand side of the burner control module you'll see 4 capacitors - the capacitors have most likely failed...pretty sure anything code 76 is P/S failure. It may also be covered for manufactures defects. If the cap is blown..the top will be slightly raised as apposed to flat like the other nearby caps - they are called top blow capacitors...the damage should be evident.

SOURCE: i have a 250SX aquastar bosch tankless hot water

The 250 MUST have the condensate line connected. EC comes from gas supply problems and CO2 levels not being adjusted. LP units require 3/4" smooth gas pipe or 1" corrugated pipe minimum size. The LP regulator needs to be turned up to about 13 inches of water column and with all the gas appliances on, measure no less than 11 inches of water column. The CO2 levels must be measured by a qualified gas technician with a calibrated (with in 6 months) CO2 analyzer.

Installed a jacuzzi tankless water heater when I turned it on it beeps and has an 11 in the display what does this mean and how do I fix it


The error 11 indicates that the burner did not ignite the incoming gas properly. Make sure that the gas valve is open (at the water heater and the meter/tank, depending on the type of gas). If you have propane, check that the tank isn't empty. Make sure that the water heater is properly grounded.

The other causes for the error may require a professional to check them out. Check that the water heater is compatible with your incoming gas. (Propane burners do not work with natural gas and the reverse is true, as well.) Check that the gas pressure available is high enough for the unit. (Tankless water heaters often need larger diameter pipes to bring in the gas than their tanked predecessors.) Check that there is no air in your gas lines. Make sure that the condensation collar was correctly installed on the water heater and that the vent pipe isn't too long. There are some DIP switches that need to be set depending on the installation; make sure that all of these are in the correct positions. Next the burner, the igniter and the solenoid gas valve need to be checked. The wiring for the igniter and the valve need to be checked. The burner cover has to be removed to check if the burners are properly seated. The burner plate has to be removed so that the burner surface can be checked for debris or condensation. The igniter has to be checked to see if it is operational. Finally, the solenoid valve needs to be checked for a short or an open circuit.

I hope this helps.

(I've also had to check the end of the vent pipes for blockages - animal nests in the summer or ice in the winter.)

How long do tankless water heaters last?


if the tank is stainless steel it should last 30 years or more however most are not and if they last 10 years it still is not cost effective since they cost so much more than conventional

Disconnected condensation drain on hot water heater.


Tankless or hybrid water heater?

Tankless gas must have special fitting between water heater and vent that has a condensate line fitting. Hot toxic vent gasses traveling up vent pipe cause acidic water vapor to form inside vent pipe that drips back down vent and drips onto heat exchanger and other parts eventually burning hole through expensive metal alloy heat exchanger, rendering tankless computer water heater useless after electric circuitry gets wet and shorts out.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#vent

Hybrid or heat pump type computer water heaters must have condensate drain connected to catch pan located just above storage tank and below compressor. Condensation can form on condenser coils and drip into catch pan where there is primary and secondary drain

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:

No condensate coming out of the condensate drain just blows out air


Call Rheem and they will recommend calling installer since tankless computers are non intended as do-it-yourself.
If condensate drain is blowing out 'air' do not forget this air is deadly poison CO gas and will kill you, first giving you a headache that goes away when you are out of house. Remove affected people from home and put into fresh air and lay on side, never on back or they will suffocate. Call 911 immediately and most will recover.
Copy following link for resources and required maintenance for tankless computers that heat water: scroll down to venting and manuals and review each to check how vent lines are set up, and that condensate line is set correctly. However this information is NOT guaranteed to match each model made by Rheem as they advance their product marketing strategy to exclude as much safety information as possible for do-it-yourselfers.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Condensate lines can clog over time. Clean line with compressed air, and soak in clorox, and swing around overhead to remove anything inside line. This line contains bacteria so do it in neighbor's yard.
Not all conditions produce vent condensate. Condensate might not form in vent line if weather is dry and the vent has good draft. But later when conditions change, condensate might begin flowing.
Condensate is caused from burning hydrocarbon fossil fuels in any gas appliance. But problem is bigger with tankless since these appliance consume so much fuel per heating event since tankless are required to heat water rapidly as water passes by in a pipe. This is why tankless require larger incoming gas line, and larger vent line made from specific materials for the vent.
Among the long list of poisonous by-products being vented outdoors into the air our planet breathes is acidic water vapor. If conditions are such that the vapor condenses before reaching outdoor, then the acidic water gathers in the vent line and rolls back toward the tankless computer, and goes down into the condensate drain and then down into your pluming drain where it can corrode pipes and add acid by-product to other environments.
If the acidic water is allowed to fall back into tankless heat exchanger instead of down condensate drain, then eventually it will chew a hole through the special nickle alloy heat exchanger (imagine the hole it will chew through household drain lines), and the surprise will not be evident for a few years until leak develops and the tankless exchanger must be replaced at great expense, plus repairs to shorted motherboard and electrical sensors.
Just don't install tankless computer water heater is best solution for myriad of problems, maintenance, and expense of owning a device that must immediately monitor incoming and outgoing water temperatures and flow rates, incoming gas flow rate and pressure, outgoing vent flow and pressure, interact with a remote control device, while monitoring burn rates and combustion temperature using a computer motherboard that is not protected from line interference or power surge, etc
Just install tank-type heater:

How do you fix rinnai tankless water heater code 79


Do not spend 500 on plumber to determine that condensate drain was not installed properly on vent line, and that acidic water from combustion by-product has been dripping down into tankless and burning hole through the special-alloy heat exchanger instead of going down into floor drain and corroding your plumbing pipes.
Do not spend hours fulfilling the required monthly and yearly maintenance, or spend money on service call each year to get the burner cleaned and gas pressure checked on your tankless computer that heats water...
Instead, fix any tankless problem, any brand tankless, same day do-it-yourself for $385, by replacing 1 part: the whole thing:http://waterheatertimer.org/How-to-install-gas-water-heater.html
Do not install tankless.

Jacuzzi tankless water heater code 12 appears


For my Jacuzzi tankless water heater model #J-SN180F: It turned out to be an exhaust issue. If I take off the exhaust vent completely then the talks heater works with 3 baths at full hot water. I get the error code 12 again as soon as I put event an elbow of the vent. So my conclusion is I need some sort of straight vent.

Code 14 comes up on the remote what does that mean


Before calling Rheem or service technician, open following link for troubleshoot resources including error codes, Rheem chat, typical required maintenance manual, and possible product manual:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Error codes are start point for troubleshoot.
Error 14 is 'overheat wrap fault.'
This can include venting problem, failed heat exchanger, bad safety circuit, gas problem.
Rheem does not have a service manual posted for this specific problem.

Additional information: Tankless water heaters consume large amounts of gas during combustion. The combustion burns away hydrogen and the remaining poisonous byproduct is vented into the atmosphere at each home day and night.
Byproduct includes acidic water vapor that condenses along the vent pipe and drips back down vent.
Each tankless vent pipe has a drain line that directs acidic water into household drain.
If this drain line becomes clogged, or if vent was not installed correctly, then water drips down into heat exchanger and can erode or crack exchanger.
The typical maintenance manual above shows steps that can solve many tankless problems before they happen.
