Traditional Hot Water Tank vs Tankless

The main difference between tankless water heaters and hot water tanks is that tankless models only use energy when you turn on the tap. You aren’t paying to store a huge tank of water while you’re away, at work or at night when you’re sleeping.

Tankless water heaters

Tankless water heaters do cost more to purchase and install than traditional hot water tanks, but you get these main advantages:

  1. Much lower energy costs. Because you only heat water when water is flowing, your energy costs will be much lower than with tanks – depending on your usage habits, you could see anywhere from 30 – 70% savings.
  2. You get as much hot water as you can use. Tankless water heaters are also called “on demand” because they don’t run out of hot water. This is great for larger families or people who have guests who stay frequently. This means no more cold showers! 
  3. Smaller footprint. Tankless models mount on your wall, so they save room in your basement utility area.
