If there's room in the bathrooms (e.g., on the wall, under the sink), you can install the "instant hot water" heaters that are used in much of the rest of the world. They only turn "on" when you turn on the faucet (sometimes they're controlled by an electric switch, either on the unit or on a nearby wall). In other words, they are not heating and re-heating the water when there are temperature fluctuations where the heater is located, although there is no immediate use for hot water. The speed at which they deliver hot water -- and lots of it -- is amazing.

If I could afford it, I would definitely have one of these in each of my two bathrooms. Try doing some internet research. The prices and specifications can vary quite a bit, depending on how you decide to set it up. You might need a plumber and an electrician!

One thing you could do, especially if you have an unfinished basement would be to install a potable water recirculating pump. (impeller and housing have to be rated for potable water. ie: not cast iron.) There are manufacturers who sell small potable recirc pumps that operate either on a timer or on a thermostat. Then when you want hot water it's just a moment away and zero water is wasted.

You will need to install a return water line to the water heater, you will also want to insulate the hot water and hot water recirc lines to save energy.

There is another cheaper way, which I don't care for. You can tie the hot and cold water lines together at the furthest fixture with a special tee that has a small check ball in it. The hot water pushes the cold water so you have hot water instantly. The problem is your cold water will be hot, then warm for a while.

Good luck.
