We replaced a Paloma which had a pilot light with the Bosch which has a water wheel piezo electric starter. The Bosch starts with less water flow and heats with less water flow. They don't refer to them as "on demand" water heaters for nothing. If you don't demand enough hot water, you don't get any. With the Paloma we had to have the hot water tap all the way open to get it to demand enough hot water that the water heater would turn on. The Bosch starts on a much less hot water demand. The Paloma was a much bigger unit than most of them, though. It may have been over sized for our residential use.
The Bosch also has a ductless heat vent. No need for through the roof vent piping, just put it on the wall somewhere with outside ventilation. Ours is on the leeward side of the house out of most of the weather and seems fine there.
