Got it, thanks! I had a feeling it was something like that. Is the booster an 'on demand' device or does it have to run for a while and heat up a holding tank? All our hot water comes through an 'on demand' heater that only turns on when we turn on the faucet, and only heats the water that we need to use at the time.
