What is the best replace the elements and thermostats or just get a new waterheater


Best is to replace anode rod, and leave elements and thermostats alone until they go out. IF you can get the anode out.
http://waterheatertimer.org/Replace-anode-rod.html
Anode rod prevents tank from rusting. Anode rods deplete over time in most situations, and then tank begins to rust. If the anode can be successfully removed, and updated, then tank rusting stops, and you're tank is good for another 10 years.
So answer to question is: Depends if tank is rusty, and if tank is sitting in drip pan to protect home from possible leak.
http://waterheatertimer.org/Leaking-water-heater.html
Tank-type electric heater is unique since it can last almost indefinitely, with maintenance. Therefore maintaining tank-type electric water heater can pay you $5-10 per month.
http://waterheatertimer.org/How-to-maintain-water-heater.html
Ordinary electric tank type can outlast all other water heaters, and be far simpler to fix yourself than any other type heater: including gas tank-type, electric hybrid tank-type, electric-and-gas tankless etc. More complicated heaters will eventually fail, and the lifespan is limited. Which is argument against buying expensive water heaters that are controlled by computer chip etc. Avoid tankless promotion. Tankless cost more..Period.

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.

Water not as hot as it was.


Tankless require yearly service to keep burner and combustion parts clean and check electrical connections, gas solenoid, gas pressure, venting, etc.
Read product manual for advisories and recommended maintenance.
Yes, aren't you glad you saved the manual.
Always check that local area has affordable and qualified service technician for your brand before buying tankless.
Before calling service technician, copy following link for general troubleshoot resources, including some manuals, and links to Bosch.
http://waterheatertimer.org/pdf/No-Error-Code.pdf
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

Try turning temperature down.
The fact there is no error code, and the gas is not firing correctly, means you have a small unit with no error codes and PC board has failed ... or it means you have a unit with error codes and possibly bad PC board.
If problem is the PC board, then Bosch will send you new board, and expect same level of repair success as though your computer's motherboard was replaced.

You can buy ordinary box-store tank-type heater and install yourself same day for about $325.
Then maintain and fix it yourself. I recommend AO Smith/American/State/Reliance/Kenmore/Whirlpool since these are easy to maintain with clear directions in manual, plus AO Smith posts service manuals for the whole line of products, and any local plumber can fix them with ez-to-locate generic parts.

Typical Bosch Aquastar manual:

All tankless and tank-type gas water heaters require regular cleaning and maintenance.
It is unknown if your unit needs maintenance or repair parts, but catching up on maintenance using information from manual is good place to start.
Gas appliances are increasingly complicated and experienced technician is good resource to have in local area before installing tankless.

I have a bosch aq125 ding? the hot water is not sufficient to the temperature for a health dept to pass the restaurant to stay open. how do i get a hotter temp? is there something that is clogged or not...


That is a residential unit and at maximum will raise water temp 90 deg at 2 gallons per min.. You need at least one commercial unit with a thermostat that will allow high enough water temp. to pass health dept. requirements, and a self heating dishwasher at a minimum.
