South Barrington estate homes with four to six bathrooms — and the simultaneous demand that goes with them — are exactly the homes where tankless systems justify the investment. A standard 75-gallon tank peaks out fast. A properly sized Navien, Rinnai, or Noritz tankless unit delivers unlimited hot water on demand, for 20+ years, with lower operating costs than the tank it replaces.
Three factors make South Barrington one of our strongest tankless markets.
A home with five bathrooms, three teenagers, and a dishwasher running at 7am puts serious strain on any storage tank. Even a 75-gallon unit heated to maximum temperature runs out within 30–40 minutes of sustained simultaneous draw. Tankless eliminates the ceiling entirely — the hot water supply is theoretically unlimited as long as the unit is sized correctly.
South Barrington's development era (1995–2015) means a large number of original builder-grade water heaters are now reaching or passing the 12-year mark. Rather than replacing one standard tank with another, many homeowners choose this moment to upgrade — converting to tankless eliminates the 10–12 year replacement cycle entirely.
Tankless carries a higher upfront cost than tank replacement. In a South Barrington home that will be owned for 15+ more years and uses significant hot water, the math works: lower energy bills, no tank replacement in 10 years, and a selling point when the home goes to market. High-efficiency systems may qualify for federal or utility incentives. Confirm eligibility with your tax professional or utility provider.
We install all three and recommend based on your home's specific configuration and demand — not on what we have most of.

Tankless installation in South Barrington runs $4,200–$7,500 fully installed — unit, gas line work, PVC venting, copper connections, haul-away, and disposal. Gas line upgrades (common in older South Barrington construction) and complex venting runs push cost toward the higher end. Call (847) 847-4978 for an upfront quote specific to your home.
Many South Barrington homes have half-inch gas lines from original construction — sufficient for a standard tank but undersized for a high-BTU tankless unit. Most 180,000–199,000 BTU tankless systems require three-quarter inch minimum gas supply. Premier assesses your gas line as part of the quote and includes any upgrade cost in the estimate upfront. No surprises after work begins.
For most South Barrington homes — particularly those with 4+ bathrooms and high simultaneous demand — tankless delivers a meaningful return over the unit's 20+ year lifespan. Lower standby energy loss, elimination of the 10–12 year tank replacement cycle, and unlimited hot water are the primary benefits. High-efficiency systems may qualify for federal or utility incentives. Confirm eligibility with your tax professional or utility provider. Call us and we will give you an honest assessment of whether tankless makes sense for your specific home.
A tankless-to-tankless swap takes 4–6 hours. A full conversion from a tank system — which involves gas line work, PVC venting installation, and complete copper replumbing — takes 6–8 hours. Most South Barrington conversions are completed in a single visit. We schedule these next-day rather than same-day to arrive with the correctly sized unit and all required materials.
Yes, with proper sizing. Homes with 5–6 bathrooms running simultaneous demand require a high-output unit — the Navien NPE-240A or Rinnai RU199iN both deliver 199,000 BTU and can handle very large simultaneous loads. For truly exceptional demand, a parallel dual-unit configuration doubles flow capacity. We size every installation based on your home's actual peak demand — not a default recommendation.
