Hot water is a MUST for a happy home! Without it, you can't wash dishes, wash your hands properly, or take a shower or bath. We're all willing to pay a higher gas bill if it means we get plenty of hot water every day.

But what if there's a cheaper way?

Tankless water heaters are significantly cheaper than regular water heaters. The fact that they ONLY heat up water when you need them means you save a lot on your gas bill every year—between $44 and $108, depending on the type of water heater you have.

Sure, tankless water heaters aren't perfect—they're pricier than regular water heaters and can be inconsistent with hot water output—but they're the eco-friendly, energy-saving option to consider!
