Not only will tankless water heaters give you back more space, but they also function in a completely different way than standard tank-style water heaters, which heat all of the accumulated water at the same time. The concern with that is—if the heated water doesn’t get used up—the water cools down and will need to be reheated, wasting time, energy, and money.
Tankless water heaters take advantage of gas burners or electric coils to heat water just when it’s being used, leading to major savings on energy bills. Think what it would be like to have an endless supply of hot water. Yes, with a tankless system you can use your dishwasher AND still get a comfy hot shower! They are economical in size, energy-efficient in design, and cost less to run.
