This water heater has been a huge disappointment to me. From the very first,
it has had problems with maintaining the temperature. I simply cannot get it to stay at the nice, warm temperature that I want. Every time I shower, the water changes from really hot, and when I turn it down, it goes to really cold again. There is NO in between with this heater. So it makes showering no fun, it’s impossible to take a long shower without interruption.
This is caused because my nice shower head filter supposedly lowers the water flow or pressure too much, and this causes the flow sensors to turn off the water heater gas flame! So I talked to Tech Support SEVERAL times, and even then, I was on hold for 1.5 hours once on their phone line. They sent me out a new set of temperature sensors, little buttons that I replaced easily via clip on to the water line. We also tried changing the temperature setting down lower, to maybe 106 F. so that it might be more efficient. Well, nothing worked. They suggested I should turn on another faucet when I shower, which keeps the water flow ‘high enough’ for the burner to stay turned on.
They also said I should remove my shower filter. It just works this way, it needs enough water flow to work right.
It is also a big expense to install, because I had to pay 2000.00 for installation, with a new dedicated gas line from my meter directly to the heater, and a fancy stainless steel vent, direct to the outside, for the air vent.
If you ever want a shower filter, or if you have any low pressure for any reason in your home, do not buy this piece of equipment. It is NOT tolerant of any fluctuations in water pressure. It also behaves differently when the incoming water temperature is higher or lower, because the gas flame has to sense the incoming water and adjust its output. It will overshoot in the summer, because the burner stays on too high when the water is ‘warmer’ than normal. This doesn’t seem to me to be reliable. I hate the finicky nature of this water heater, and I would never buy one ever again.
In my case, I need my shower filter to eliminate chlorine and minerals, or else my skin gets a rash. So I am out of luck with this thing, Bosch says that filters drop the water flow too much, either a shower filter or a whole house filter.
