Could someone give me info about tankless water heaters?
Tankless water heaters heat water only when you turn on your hot water faucet. That can save a lot of energy because there is no large tank of hot water cooling off all the time. The water heater must be big enough to handle the largest hot water flow or combinations of flow you expect to ever need. For instance of the heater will heat enough for a single shower flow and then someone turns on a second hot water faucet the water will cool down. Tankless heaters are more expensive and require a more energy when they are on than a tank type heater. In some cases the existing electrical or gas service may not be large enough and would need to be upgraded. I included links to a couple of sites that give lots of more information below.
