Possible flow sensor issue. Check to see if your water pressure fluctuates a lot or is fairly steady. These units are sensitive to the pressure. take care.

Takes a long time to heat water. Brand new Ge 50 gallon water heater. Once heated it right temp,just a long time to heat it and then won't maintain hot water. Is gas line to small? 3/8 copper line. Thanks


If you are using a 3/8" copper line for your gas, get it replaced ASAP. It will fail. 1/2" Black Iron is required with natural gas. 50 gallons is a lot of water to heat. Look on the heater label for the recovery rate.

Won't get hot enough or last as long as it used to

Bosch water heater won't heat as hot or as long as it used to.


Is it protected by a water softener?

Have you cleaned the inlet screen and flow valve?

Your problem is likely in one of those areas. If not them then you may have to backflush the heat exchanger (if you don't have a softener). The manual tells you how to do that.

Bosch 1600h NG not heating water hot enough


it sounds to me like the dip tube has failed. this is a plastic tube that is inside the water heater on the cold side. It is designed to put the incoming cold water at the bottem of the tank allowing heated water out at the top. when this tube deteriorates the cold water mixes at the top of the tank instead of the bottom. a new dip tube is about 5 bucks but must be inserted on the cold side by someone with plumbing experience.
