Water gets warm but not hot on our 125B tankless bosch

Yes, ours only really works in the summer (warmer weather) There are about 3 months in the year we have to shower upstairs where we have a tank style heater still. Crazy is we live in Texas. Can't see this heater working in colder climates. I would never buy one of these again.

Is this a new unit? If it is, you might consider warranty repair. If it's been in service for a while, I would look at the unit while hot water is running to see if you have plenty of flame coming from the burners. I've never had problems with the water being only warm on my unit, usually too hot.

As soon as the water gets warm it reduced the water flow. The sensor temp can not be adjusted its automated

Same issue with this and a former model for us. The solution is to turn it down. Yes the water isn't as hot, but...

The reason your temp isn't going up in the tank is because there is no water movement in the pump chamber. The only way to remedy this is to punch small holes in the plastic tubing which runs from the pump to the outlet. This will get the water flowing inside the small chamber where you are keeping the heater.

I am not able to answer that. We have had this unit for about 6-7 years and we always have hot water. I have a one bathroom house but am able to use at least the dishwasher and washing machine at the same time or take a shower with one of those going, also. I love this unit! It has worked much better and longer than the Bosch unit that we had before.

The only thing I've noticed different from my tank water to my tankless, is it takes a little long for the hot water to get hot. But once the water is hot,it stays hot. Ihave been extremely satisfied with the rheem. I can run just a hand sink or I can run 2 showers 2 sinks plus my dishwasher and still have plenty of non stop hot water.

it heats the water in the machine but does not reach steam temperature. I'm not sure how hot water gets but hot enough to work on stains.

Water doesn't get hot, at least not on mine. I've only used it a couple of times so far. Sorry can't be of more help. Carol

If it is not getting any hot water at all it is probably a problem in the burner or lighting mechanism, if you are getting warmer water then the tap water you might not have a large enough gas line to the heater.

Ours stays on a lot but it's not boiling the fish. LOL I really don't know what to tell you except to contact the factory. Good luck!

It is normal for the water unit to be hot as the water is heated. However, my unit malfunctioned that I had 2 or 3 units eventually after warranty replacements and none were satisfactory. Have replaced with April air unit which is much superior.

It can get pretty hot. As long as it is not making a lot of noise (bearing) and it is pumping water, it should be fine. I would just keep an eye on it for a while.

I have a couple of these in some 10 gallons. Make sure your heater and thermometer are not too close. When the heater coils turn on they make the surrounding water rather warm. You may have experienced a 80 reading when the pilot light was on and coils were hot.

Yep, the heat may be shut off (via a switch in the back) thereby just giving room-temp water. The cold water has a stat / adjustment nob. I've simply left it at the factory setting...cold but not too cold for me...

Let the water get tepid or lukewarm, before adding water. Do you use a heater? if so, set it the water to the temperature in the tank before adding.

Your system is under designed for the application. How far is the hot water going from the heaters, and being recirculated? My guess is you've exceeded the over length for your setup. Or possibly something's effecting your system. I.E. One units out or you have pipe that not insulated. Your tank heaters is on and heating at full power constantly, that's the only thing that will burn the elements so fast, under normal conditions the elements last 10years. Sometimes water quality can affect the length of time a element will last. But it's really rare to have to replace them that fast. Hard to say what will fix it without details. These little things are designed to go under a sink and heat just enough water to wash your hands etc... Not heat a whole house.
