I grew up in an apartment with a tankless heater. If the heaters now are similar to that one, you adjust the temperature using a control at the heater, rather than by mixing hot and cold water, as you do when you have a hot water tank. If you try to mix, the heater turns off because the flow of water through it is too low. This makes it rather impractical to put a tankless heater in the basement -- it has to be close to the point of use. In addition, the point in using a tankless heater is to minimize losses, and if the heater is as far away from the point of use as in the case of a hot water tank you have not gain anything.
