Water Heater Installation in Arlington Heights, IL

We install, replace, and upgrade every type of residential water heater available in Arlington Heights:

Conventional Tank Water Heaters — The most common type in Arlington Heights homes. Available in 40, 50, and 75-gallon capacities in both gas (natural gas via Nicor Gas) and electric models. Modern high-efficiency tanks achieve 0.65–0.70 UEF ratings for gas and 0.92–0.95 for electric, significantly reducing energy costs compared to older units.

Tankless (On-Demand) Water Heaters — Gas-fired or electric units that heat water only when needed, eliminating standby heat loss. Whole-house gas tankless units deliver 8–11 GPM of hot water — enough for multiple simultaneous showers. Ideal for larger Arlington Heights families or homes where the water heater is in a tight space.

Heat Pump (Hybrid) Water Heaters — The most energy-efficient option available, using heat pump technology to achieve 3.0+ UEF ratings — 2–3x more efficient than conventional electric tanks. Requires adequate space (at least 700 cubic feet of air space) and works best in basements with ambient temperatures of 40–90°F. Federal tax credits of up to $2,000 are available through 2032.

Power Vent & Direct Vent Gas Water Heaters — For Arlington Heights homes where the existing chimney flue isn't available or adequate, power vent models use a fan-assisted PVC exhaust that can vent horizontally through a wall. Direct vent models draw combustion air from outside, improving safety and efficiency.

Point-of-Use Water Heaters — Small electric tankless or mini-tank units installed under a sink or near a specific fixture for instant hot water without waiting for the main water heater to deliver. Ideal for distant bathrooms or kitchen additions.

Knowing when to replace vs. repair saves you from both premature replacement costs and emergency failures:

Age — Tank water heaters typically last 8–12 years. Tankless units last 15–20 years. Check the serial number on the manufacturer's label — the first two digits often indicate the year of manufacture. If your tank is 10+ years old, replacement is usually more cost-effective than major repairs.

Rust-Colored Water — Rusty hot water (but clear cold water) typically indicates the tank's interior lining is deteriorating. Once the glass lining cracks, the steel tank corrodes and will eventually leak. This is not repairable — replacement is needed.

Leaking Tank — A leak from the bottom of the tank means the tank itself has corroded through. This is an immediate replacement situation — the leak will only get worse. A leak from fittings or the T&P relief valve may be repairable.

Insufficient Hot Water — If your water heater can't keep up with your household's demands, it may be undersized, have a failed dip tube, or have significant sediment buildup reducing capacity. We can diagnose whether repair or upsizing is the better option.

Rising Energy Bills — An older water heater loses efficiency over time due to sediment buildup, deteriorating insulation, and component wear. A new high-efficiency unit can reduce water heating costs by 20–50%.

Frequent Repairs — If you've had multiple repair calls in the past 2 years, replacement is typically the better investment.

Proper sizing ensures you always have enough hot water without overspending on an oversized unit:

Tank Water Heater Sizing (by household):

• 1–2 people: 30–40 gallon tank
• 3–4 people: 40–50 gallon tank
• 5+ people: 50–75 gallon tank or consider tankless

Tankless Water Heater Sizing: We calculate the required flow rate (GPM) based on the number of fixtures you want to run simultaneously and the temperature rise needed. In Arlington Heights, incoming water temperature drops to approximately 37°F in winter, requiring a higher temperature rise (about 83°F to reach 120°F output) compared to summer. This means your tankless unit needs to be sized for winter performance — many undersized units deliver inadequate hot water in January despite working fine in July.

First-Hour Delivery Rating — For tank water heaters, the first-hour delivery (FHD) rating tells you how many gallons of hot water the unit can deliver in the first hour of heavy use. This is more important than tank size alone. We calculate your peak-hour demand and match it to the right FHD rating.

We assess your household's hot water usage patterns and recommend the right size and type for your specific situation.

1. Assessment & Recommendation — We evaluate your current water heater, household hot water needs, available fuel sources (gas vs. electric), venting options, and space constraints. We recommend the best replacement option and provide a detailed written estimate.

2. Permit (When Required) — The Village of Arlington Heights requires a plumbing permit for water heater replacement when changing fuel type, venting configuration, or location. Like-for-like replacements in the same location may not require a permit depending on the scope. We handle all permitting.

3. Old Unit Removal — We drain and disconnect the old water heater, cap gas and water connections, and remove the unit for proper disposal.

4. Installation — We install the new water heater with all required connections: water supply (hot and cold), gas line or electrical, exhaust venting (for gas units), condensate drain (for high-efficiency gas or heat pump units), T&P relief valve with discharge piping, expansion tank (required by code in Arlington Heights for closed-loop systems), and seismic strapping.

5. Testing & Commissioning — We fill the tank, purge air, light the pilot or activate the unit, check for gas leaks (gas units), verify proper venting and draft, set the thermostat to 120°F, and test hot water delivery at fixtures.

6. Walkthrough — We show you how to operate the new unit, where the shutoffs are, and provide maintenance recommendations.

Conventional Tank Water Heater (40–50 gallon gas):

• Equipment: $600–$1,200
• Installation labor: $400–$800
• Total installed: $1,000–$2,000

High-Efficiency Tank Water Heater (power vent gas):

• Equipment: $1,200–$2,000
• Installation labor: $500–$1,000 (PVC venting adds complexity)
• Total installed: $1,700–$3,000

Tankless Water Heater (whole-house gas):

• Equipment: $1,500–$3,000
• Installation labor: $1,000–$2,000 (gas line upsizing, venting, condensate drain)
• Total installed: $2,500–$5,000

Heat Pump Water Heater:

• Equipment: $1,500–$2,500
• Installation labor: $500–$1,000
• Total installed: $2,000–$3,500
• Federal tax credit: up to $2,000 (reducing net cost significantly)

Factors that affect cost:

• Converting from electric to gas (or vice versa) — requires new gas line or electrical circuit
• Relocating the water heater to a different location
• Bringing old installations up to current code (expansion tank, new venting, updated gas connections)
• Emergency/same-day replacement vs. scheduled installation
