Water Heater Installation: Choosing the Best Option for Your Needs

When your water heater fails, it feels like the world stops. Cold showers. Dishes piling up. Work and home routines thrown off—all because of one essential appliance. At Aark Plumbing, we understand the urgency and stress a broken water heater brings, whether you’re running a busy household or managing a commercial property.

With decades of experience in emergency plumbing, we help families and businesses get back to normal—fast. Let’s walk through how to choose the right water heater, what to expect during installation, and how to ensure years of hot water comfort.

Types of Water Heaters

Think of water heaters like shoes: different occasions call for different styles. Here are the main types you’ll find in homes and businesses today:

• Tank Water Heaters: The classic. Stores 30–80 gallons of hot water, ready when you need it. Typically powered by natural gas or electricity.
• Tankless (On-Demand) Water Heaters: Heats water as you use it. No big tank, just steady hot water. Great for saving space and energy.
• Heat Pump Water Heaters: Uses electricity and ambient air to heat water. Like a reverse refrigerator—efficient but best in mild climates.
• Solar Water Heaters: Uses roof-mounted panels and sunshine to heat water. ROI depends on your region’s sunlight.
• Condensing Water Heaters: High-efficiency gas models that capture and reuse exhaust heat.

Each type has its pros and quirks. For example, tank models are reliable but can run out of hot water if overused. Tankless units rarely “run dry” but may require upgraded gas lines or electrical service. Heat pump and solar models offer energy savings but may cost more up front.

How to Choose the Right Size 🔍

Picking the right size is like picking Goldilocks’ porridge—not too big, not too small. Too small, and you run out of hot water. Too big, and you waste money heating unused water.

Sizing for Tank Water Heaters

• Residential:

  • 1–2 people: 30–40 gallons
  • 3–4 people: 40–50 gallons
  • 5+ people: 50–80 gallons
    These are guidelines—busy households or homes with oversized tubs may need more.

• Commercial:

  • Consider peak hour use. Restaurants, gyms, salons, and offices all have different demands. Refer to your building’s occupancy and fixture count.

Sizing for Tankless

• Measure in Gallons Per Minute (GPM):
  • Shower: 1.5–2.5 GPM
  • Dishwasher: ~1.5 GPM
  • Washing Machine: 2–3 GPM

Add up simultaneous uses. For example, shower + dishwasher + sink = 5–7 GPM minimum.

Tip: Use the U.S. Department of Energy’s sizing charts for reference.

The Installation Process

Water heater installation isn’t just swapping out an old box for a new one. It’s more like a relay race—one step depends on the last.

Step-by-Step Overview

1. Turn Off Utilities: Gas, electricity, and water must be safely shut off.
2. Drain the Old Tank: Avoid flooding your utility room or workspace.
3. Remove the Old Unit: Disconnect lines and venting.
4. Update Connections: Sometimes, pipes or gas lines need upgrades to meet current codes.
5. Install the New Heater: Position, level, and secure the unit.
6. Reconnect Utilities: Attach water, gas, and venting. Double-check for leaks.
7. Test and Adjust: Fill the tank, check temperature, and inspect for drips or strange noises.
8. Code Inspection: Many areas require a certified inspection for new or replaced heaters.

For tankless and heat pump models, expect extra time for electrical or venting work. Commercial installs may require after-hours scheduling to minimize business disruption.

Efficiency and Cost Considerations 💡

Water heaters are long-term investments. The sticker price isn’t the end of the story—think “miles per gallon,” not just “purchase price.”

Efficiency Ratings

• Energy Factor (EF) or Uniform Energy Factor (UEF): Higher numbers mean better efficiency.
• Insulation: Newer tanks have better insulation, reducing standby heat loss.
• On-demand vs. Storage: Tankless units save energy by heating only when needed.

Cost Factors

• Upfront Cost: Tankless and specialty models cost more but may save money over time.
• Operating Cost: Gas is usually cheaper than electric. Heat pump and solar models use less energy.
• Maintenance: Tank units need periodic flushing. Tankless units may require annual descaling.

Reference: ENERGY STAR and the U.S. Department of Energy offer helpful guides for comparing costs and performance.

Warranty and Code Compliance

Water heaters aren’t just appliances—they’re regulated for safety.

• Warranty: Most water heaters come with 6–12 year warranties. Register yours after installation for full coverage.
• Local Code: Cities and states often require permits and code inspections. For example, California has strict seismic strapping rules. New York requires backflow prevention devices in certain buildings.
• Certified Installers: Always use a licensed plumber. Certified installation protects your warranty and ensures you’re up to code.

Quick Safety Checklist 🛑

Before you start—or let anyone else start—run through these basics:

• Turn off power or gas supply to the heater.
• Let the water cool before draining.
• Check the area for combustible materials.
• Ensure proper ventilation for gas units.
• Have a fire extinguisher nearby.
• Know your main water shutoff location.

Safety isn’t a game. According to the National Fire Protection Association (NFPA), improper installation is a leading cause of home fires involving water heaters.

DIY vs. Call a Pro

Installing a water heater might seem like a weekend project. But there’s more to it than meets the eye.

• DIY Risks:

  • Gas leaks or carbon monoxide danger
  • Scalding risk from incorrect settings
  • Voided warranties
  • Failed code inspections

• When to DIY:

  • Simple electric tank replacement, with plumbing experience
  • No gas or venting changes needed

• When to Call A Pro:

  • Gas, tankless, or heat pump installs
  • Commercial or multi-unit buildings
  • Any time code compliance or warranty is a concern

What Pros Do On Arrival

A trained installer isn’t just there to lift heavy things. Here’s what to expect:

1. Assess Your Needs: Confirm the right size and type for your usage.
2. Check Old System: Look for hidden leaks, corrosion, or code violations.
3. Prep the Work Area: Protect floors, clear access, and set up safety gear.
4. Install and Test: Follow manufacturer instructions, city code, and best practices.
5. Inspect for Leaks: Use soap solution or detectors for gas lines. Water lines get a pressure test.
6. Explain Operation: Show you how to adjust the thermostat, flush the tank, and spot warning signs.

A professional touch means peace of mind—and a job done right the first time.

Prevention & Maintenance 🧰

Think of water heaters like cars—they need regular checkups.

• Flush the Tank: Removes sediment and extends life. Do this yearly.
• Check Anode Rod: Replace every 3–5 years to prevent tank rust.
• Inspect for Leaks: Look for drips around valves, pipes, and the base.
• Test Temperature Relief Valve: Ensure it opens and closes properly.
• Keep Area Clear: Don’t store flammables nearby.

The Plumbing-Heating-Cooling Contractors Association (PHCC) recommends annual professional inspections, especially for commercial systems.

Costs & Time Factors

Every install is unique, but here’s what typically affects cost:

• Type and Size: Tankless and larger units cost more.
• Fuel Source: Gas lines or electrical upgrades add to the bill.
• Labor: Complex installs (tight spaces, commercial settings) take longer.
• Permit/Inspection Fees: Required in most municipalities.

Typical Timeframe:

• Residential replacement: 2–4 hours
• New install or tankless: 4–8 hours
• Commercial: Varies; may require off-hours work

Remember: investing in quality installation saves money in repairs and headaches down the line.

When It’s an Emergency 🚨

A leaking tank, no hot water, or strange noises at 3 a.m.? That’s when emergency plumbing makes all the difference.

Signs of a Water Heater Emergency:

• Water pooling around the unit
• Hissing, popping, or banging sounds
• The smell of gas or burning
• No hot water, especially for medical or food service needs

If you suspect a gas leak, leave the area immediately and call emergency services. Otherwise, shut off the water and power supply, then contact a certified plumber.

Aark Plumbing is ready 24/7 for emergency plumbing and water heater issues, day or night.
