Interesting on legionella - a lot of the time there will be pipe work anyway well below a killing temperature and a short use of engine (takes about half an hour to reach full temperature) will also leave it lower. Has any legionella issues ever come from a boat’s system?It's not exactly so, because the lower power means the heater element will run cooler, so have a lower resistance than at 230V.
It might be wise to be getting the water hot enough to kill legionella?
