Is tankless a good upgrade for a Long Grove home on its second replacement?

For Long Grove homes with 3+ bathrooms and recurring hot water demand, the second or third replacement is often the right time to consider tankless. The 20+ year lifespan eliminates the replacement cycle, and unlimited on-demand hot water resolves peak-hour shortfalls. High-efficiency systems may qualify for federal or utility incentives. Confirm eligibility with your tax professional or utility provider.

Does my Long Grove home's gas line support tankless?

Older Long Grove ranch homes from the 1970s often have half-inch gas lines from original construction — adequate for a standard tank but undersized for most high-BTU tankless units. Premier assesses gas line size as part of every tankless quote. If an upgrade is needed, the cost is included in your estimate upfront.

Tankless Water Heater Installation in Long Grove, IL

Long Grove homeowners who take care of their properties tend to make the same observation when replacing their second water heater: why keep replacing the same tank every 10–12 years? A properly sized Navien, Rinnai, or Noritz tankless unit is a different kind of decision — one that eliminates the replacement cycle, delivers unlimited on-demand hot water, and carries a 20+ year lifespan — a long-term upgrade that makes sense for homeowners planning to stay.

Why Tankless Makes Sense for Long Grove Homes

🔁 End the Replacement Cycle

Long Grove homeowners who have already replaced their water heater once know the drill — the tank hits 12 years, it starts showing signs, and the process starts over. A tankless unit installed correctly lasts 20+ years. For a homeowner planning to stay in the home, that's potentially potentially the last water heater installation for long-term homeowners.

🚿 Unlimited Hot Water on Large Lots

Larger Long Grove homes with 3+ bathrooms often run into peak-hour limitations with standard tanks. A 50-gallon tank drains during back-to-back morning showers. Tankless heats water as it flows — there's no stored volume to deplete. As long as gas supply and cold water are available, the hot water doesn't stop.

⚙️ Gas Line Assessment Included

Older Long Grove ranch homes from the 1970s commonly have half-inch gas lines — enough for a standard tank but undersized for a high-BTU tankless unit. Premier assesses gas line size as part of every quote. If an upgrade to three-quarter inch is needed, the cost is in your estimate before any work begins. High-efficiency systems may qualify for federal or utility incentives. Confirm eligibility with your tax professional or utility provider.

Does my 1970s Long Grove ranch home need a gas line upgrade for tankless?

Is tankless worth the investment for a Long Grove home?

For most Long Grove homes planning to stay long-term, yes. The 20+ year lifespan eliminates the 10–12 year replacement cycle.
