Tankless water heater installation cost factors

  • Gas vs. electric: Gas tankless units usually cost more upfront but they're cheaper to operate than electric tankless units.
  • Whole-home vs. point-of-use: Whole-home tankless units are more expensive than single point-of-use (POU) units. However, whole-home units provide hot water to all appliances in your home, whereas single POUs only provide hot water to a single appliance. You may need to pair a whole-home tankless unit with several POUs depending on the size of your home and how much hot water you use.
  • Flow rate: Flow rate measures how many gallons of hot water the unit can provide in a minute. The higher the flow rate, the "larger" the water heater size and the more expensive the unit.
  • The contractor you hire: More experienced contractors generally charge more for their services, but they typically also provide higher-quality installations that won't need frequent repairs down the road.

How It Works

How we provide Red Carpet service

  1. Schedule your water heater installation

    Call (208) 629-5192 or contact us online and choose a time that works for you. We'll work around your schedule.

  2. Receive an arrival call

    A project manager will call you 30-45 min before the plumber arrives at your home.

  3. Discuss hot water needs

    Once the plumber arrives, they'll talk with you about your family's hot water needs. The plumber will also recommend a fuel type (gas or electricity) and the type of tankless unit (whole-home or point-of-use) based on your budget and preferences.

  4. Get upfront pricing—in writing

    Before our plumber starts any work on the installation, they'll give you honest pricing so there are no surprises when you get the bill.

  5. Relax while we do the hard work

    We'll do all the hard work and make sure your tankless unit is running perfectly before we leave. And we'll clean up our workspace so you won't even know we were there

Client Reviews

What our Boise clients have to say


Here's our promise to you: We'll deliver precisely what we promise for your tankless water heater installation. And if we don't? We'll make things right.

Tank or tankless?

You might consider a tankless unit if...

  1. You don't have space for a tank unit. Tankless units take up less space than a tank unit, which means they can be installed in small spaces like a closet or even on an outside wall.
  2. You want a water heater with a long lifespan. Tankless units last longer than tank units (20+ years compared to 10–15 years).
  3. You want endless hot water. Because tankless units heat water on the spot, you have an endless supply of hot water available. You're not limited to the amount of hot water a storage tank unit can hold.
  4. You want to lower your utility bills. According to Energy.gov, “For homes that use 41 gallons or less of hot water daily, demand (or tankless) water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters.”
