Will a tankless water heater work for me?

In most cases, yes! There are very few situations in which tankless water heaters will not work (you can ask a top tankless water heater technician about these), and most will work in areas where conventional storage tank water heaters would not. Most tankless water heaters are about the size of a briefcase and require about 120V, 60Hz and 3 amps of power – requirements almost any house meets.
