New water heater problems

My water heater is only a few years old and since I bought the house it's in, which is only a few years old as well I've had it shut off and when I check it the pilot is lit, but the burner is not and the water is cold so I turned the switch off and back on and it lights and I'm good for a few months or less. this has happened several times over a year. Now the burner won't light and the pilot won't either. It has an electric pilot start and I don't hear it click even showing it's trying to start. I reset the thermostat and unplugged the whole thing and nothing seems to get it to work. The fan on top runs so I know it has power. What's up with this? Is it the starter messing everything up?

I found out that the switch at the top of the tank by the exhaust fan was bad.

The switch is broken, or the voltage on the power from the wall is lower than the voltage on the tank and therefore it could only powering one thing

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.

Drawbacks And Benefits Of A Tankless Water Heater System
Consider both the positives and negatives before deciding to invest in a tankless water heater, and talk to a professional plumber for more information on how modern systems can benefit your home. Tankless water heater - modern, updated version of the traditional water heating systems - can save hundreds or even thousands of dollars. They take up a lot of space, they save energy (which translates to dollars saved) and they last longer than the old style heaters.

Energy saving - According to the US Department of Energy, gas-powered tankless water heaters can save a household around $ 108 per year. Electric tankless water heater saves about $ 44 per year.The reason for these savings are rooted in how the system functions. Rather than continue to keep the hot water and the energy loss in the process, a tankless system only heats water on demand. You only pay for what you actually will use.

Add to your house for Value - Any updates you make to your home will produce a bump in value, and add a tankless water heater is no different. A new tankless system is expected to last up to 20 years, while the traditional system only lasted a maximum of 13 years. These improvements will enhance the marketability of your home, if you plan to sell.

High upfront investment fee - A modern system that will definitely cost more than traditional heaters, which may be a drawback for some. While regular water heater will only cost a few hundred dollars, the electric tankless system can start at $ 500, and the gas system will cost at least $ 1,000, depending on capacity and manufacturers. On the other hand, because products are designed to last longer than their traditional counterparts, you can expect an extended warranty coverage in case any repairs needed because of malfunctions.

Output is limited - While the function of on-demand heating is very feature that saves you money, it can also cause you frustration if you have a lot of members of the household. When the water is heating, it is divided between all the hot water faucet open. You may find you can not take a hot shower while washing machine and dishwasher is running, and may have activities involving hot water when appropriate.

Save Space - If you are building a new home and trying to find a space in a utility closet plans to add to the traditional water heater, a tankless system could save you hours of frustration and architects. Tankless systems typically about 20 inches and 28 inches, and 10 inches thick. They are mounted on the walls in the house or placed on the exterior of the house, if properly insulated.This is a significant difference in size when compared with ordinary water heater, which measures about 60 inches and 24 inches. A tankless water heater can provide more space in the laundry room or finished basement to add storage or just expand the living room.

So it was manufactued in 1994. Most water heaters will last 5-10 years for gas and 10-15 for electric unless they receive yearly maintenance (flushing tank, cleaning) so it is already past its expected life span.

That being said, an electric water heater is more costly than a gas one. If I was in your place I would start saving to replace the unit with a tankless gas water heater, as soon as the house closed.

It might make more sense to sit the heater on some inexpensive concrete blocks (like stepping stones, purchased at a local hardware store) to raise is off the floor. The heat is causing the cool moist air under your house to condense under the vinyl mat. You could shim it off the floor with most anything that is non combustible and as little as an inch would probably give you enough clearance to stop the problem. Hope this helps!
