No Hot Water

Installed this unit about one year ago. I live in a hard water area and every two to three months, the hot water shuts down. Plumber installed a whole house filter but is it common to have to replace this every three months as I am constantly getting no hot water. Could it be a defective flow sensor??

Hard water contains a lot of minerals and depending on how hard the water is also depends on how often you must replace the filters. A much better alternative is to have a water softener installed before your hot water heater and any other sorce of domestic water supplying your home. I have one and it works great. Just be advised that you will need to replace the salt crystals every couple of months depending on the time intervals you set the timer to. If you find that the water still remains soft after two months and your filters are not to badly clogged then you may try adding salt every three or four months and see if that solves your problem. You also have to remember that your also using the water for drinking cooking and bathing so softening your water supply is very important especially if you or anyone in your household ever had any kidney stones or kidney problems.

Good luck,

Marty

Buying a new electric hot water heater and seeing two different types of elements; copper and combination. Is one type better than another, and if so, which one?


hot water systems come in three types
copper--subject to electrolyses around the heater element area where they leak life expectancy in good water areas -- possible 20 years
steel ( vitreous enamel coated to prevent rust-- subject to cracking of the covering during manufacture and transport and rusting around the ports-- life expectancy if in perfect condition - around 10 years
stainless steel-- mainly the cost but if in hard water areas is the most cost effective - life expectancy well past 20 years in harsh water conditions
the heater element are mostly copper as in the stove element and will last a long time provided the heater tank has water covering the element although the element may be stainless
however regardless of the material used it is the porcelain inside the covering that allows the element to short out and burn the cover
most hot water systems use common heater elements so it may be wise to keep operational units for future use
Best is to talk with a good plumber supply shop ( not a hard ware shop) and get all the details before buying a new system
repairing is not really an option

Have you tried turning the temperature down. If so and still have problem shut breaker off, let cool completely and then drain the tank by connecting a water hose to it.

Plumber is right.
Problem is not amount of air in attic. Problem is how hot the air is.
Oxygen molecules separate apart in very hot air and pilot light goes out since there is not enough oxygen density to support combustion.

http://waterheatertimer.org/pdf/Attic-Ventilation-and-Pilot-Outage-in-Gas%20Water-Heaters.pdf

More ventilation is needed.
Plumber is not ventilating expert, and not responsible for attic ventilation that builder failed to install. Plumber should do a survey of location before installation to make sure gasoline vapors are not stored nearby, but summer attic ventilation is gray area until more general-public folks become aware of problem. Hotter summers temperatures will spread that information.

Hire local home center to install roof vents AND soffit vents.
Note: You also need soffit vents.
Remember a vent on the roof is like sucking air out of a coke bottle. The roof vent is no good unless air can also enter the attic from another vent located in the soffit.

Another solution is electric water heater for very hot locations.
Or install solar-assisted water heater.

You had service techs and Bosch techs and neither can find a solution.
I assume you want impartial opinion at fixya.
Multiple error codes and a lack of progress by professionals implies PC board failure. BUT there could be multiple problems. Error codes are considered 'start' point for troubleshooting. Beyond that, Bosch should give you contact information to a trained professional service tech >> not just a plumber, but a guy who can do the electronic diagnostic.
Open following link for Bosch troubleshooting resources.
Tankless are high tech gadgets that cannot be exposed to more than 11 grains hardness in the water, and require continual maintenance. The cost of repairs and maintenance will never pay back from the expected $1-8 monthly energy savings.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
You can solve most tankless problems same day for $350.
Then sell the tankless unit back to Lowes or sell it for parts on auction site.

Hi,
The unit is plugged up with mineral buildup from the water going through it... it will need to be cleaned internally....this is done by running an acid solution through it to clean out the mineral buildup...

Takes too long for hot water.


You need a recirculating line. You will have to hire a plumber to run a water line from the farthest fixture or to the fixture you are concerned about on the hot side and return it back to the water heater. this will cause hot water to constantly run throught the hot water line (via the recirculating line) and when you want to draw water from the fixture, you will already have hot water right at the line.
I know this works with standard tank water heaters, but it is a lil trickier with rinnai units(but very possible) if your plumber pleads the 5th and tries to sell you another unit call the Rinnai manufacturerand ask them how.

No hot water


You may need a circulating pump but I can't explain why it was fine before and not now. What I would do is turn the supply off to the water heater along with the power, remove the outlet supply. Open all hot side faucets in the home, using compressed air blow through the pipes if the air comes back at you, then there is a blockage before the hot manifold. If air moves, shut one faucet off at a time to try and determine where the culprit is. I don't know what else to tell you other than that. If air moves through the faucet every time, then you may want to put a circulating pump on. The only other expination is that when they repaired the pipe, some debris or eccess solder is blocking the hot supply. I have seen rocks in units as well. Because of the fix, you may want to take apart each faucet in the house and using a flashlight, look in the hot supply side to see if you can find any debris in those as well. Its not unusual after a repair, to have debris caught in them. Hopefull this helps.

Hot Water inconsistent


Something you can do, following your fathers logic,   is to attach a hose to the drain of the tank and run water from the bottom of the tank into a drain untill all the sediment is removed (Water runs clean). This is normally done once a year as preventive maintenance  on all tank type water heaters. The logic sounds good to me.

You need to be skilled to work on live electrical appliances. If you are I can continue. If not you need to call a electrician or a plumber.

Make sure both thermostats are set at the same temperature. Let me know what you find.
