"tankless" water heater Do you need something at each source point (each shower, each sink, etc.?) Thanks much.
No, this is a whole-house tankless heater. It goes on the wall right next to where the old tank was. I use the freed-up space for potable water storage.
Do a search for AquaStar (made by Bosch). Ours is a medium-capacity unit. Two showers in two bathrooms at once would be pushing it a little, but it is plenty adequate for everything else.
