She wouldn't have had to wait 15 minutes after your shower either. Only time you would run the electric and gas at the same time is when you wanted to take back to back showers. On electric there is no noise to disturb anyone.
I had the gas AND electric turned on at the same time, no doubt. I'm not trying to sell the system, it is for people who like not running out of hot water. You WILL run out and it takes longer than 15 minutes to get back to full strength. Maybe YOU don't see the cost benefits, but I do so I'm just informing those who would like to know, plain and simple. The noise I referred to is barely noticeable anyways, just a nice feature to be able to turn it down (in essence "off") without it really being off.
