My Monkeys story concerns a Bosch instant-on hot water (natural gas) heater, which was made in Portugal, of all places.
The thing needs pampering … the electronics and solenoid need pre-warming with a light bulb for an hour or so before usage, now accomplished with a timer. Even then, it doesn’t work more than 80 percent of the time.
The interim solution has been to install a small five-gallon electric tank inline but AFTER the Bosch, which has a number of benefits, such as eliminating the filling of the hot water lines with cold water every turn-on (as it takes about 10 seconds of the tap running full in order
to activate the Bosch). Thus quick on-and-off usages of hot water (such as brushing ones teeth, rinsing hands, etc) don’t result in pulses of hot and cold water.
