Bosch HydroPower 16H, (or also the Bosch 10p) I purchased this Bosch instant hot water unit to replace a gas storage water heater in order to save space and also as it’s meant to be more energy efficient.
It has a problem where occasionally it can take minutes for the gas to light. In this video it shows my housemate trying to have a shower and waiting between 3 and 4 minutes for the gas to light. Bosch looked at it twice during warranty when I reported this problem but did not diagnose nor fix the problem.,
