Why Go Tankless?

Tankless water heaters give you:

1. Endless hot water on demand (when properly sized)
2. Better efficiency (no standby heat loss like a tank)
3. Longer lifespan than traditional tank units
4. Compact, wall-mounted design for more usable space
5. Cleaner performance (no stored sediment sitting in a tank)

Whether you’re building, remodeling, or replacing an older tank unit, a tankless upgrade can be one of the smartest long-term plumbing investments you can make.

‍

Our Tankless Installation Includes (Gas/Propane)

Every install includes:

1. On-site sizing based on your home’s hot water demand (not guesswork)
2. Navien vs. Rinnai recommendations based on your goals and budget
3. Verification of gas or propane supply for proper performance
4. Proper venting and safety compliance
5. Full testing, cleanup, and walkthrough
6. Haul-away of the old tank if you’re replacing an existing unit

We install whole-home tankless systems and (when appropriate) solutions for specific areas of the home.

‍

Is Tankless Right for Your Home?

Tankless systems are a great fit if:

1. You have 3+ people in your home
2. You want strong, consistent hot water for showers and tubs
3. You run multiple hot-water uses at once (showers + laundry + dishes)
4. You want a space-saving wall-mounted unit
5. You’re replacing a water heater that’s 10+ years old

Not sure if tankless makes sense for your setup? We’ll assess your home and give you an honest recommendation — tankless upgrade or tank replacement.
