Tankless Water Heaters: Are They Right for Your Santa Fe Home?

Tankless Water Heaters: Are They Right for Your Santa Fe Home?

Tankless water heaters, also called on-demand or instantaneous water heaters, heat water only when you need it. Learn if this technology is right for your Santa Fe home.

How Tankless Water Heaters Work

Unlike traditional tank water heaters that store hot water:

• Cold water flows through the unit when tap is opened
• Gas burner or electric elements heat water instantly
• Hot water delivered on demand
• No storage tank needed

Benefits of Tankless Water Heaters

1. Endless Hot Water

• Never run out during showers
• Multiple simultaneous uses
• Great for large families
• Back-to-back showers no problem

2. Energy Efficiency

• 24-34% more efficient than tank heaters (for homes using <41 gallons/day)
• No standby heat loss
• Only heats water when needed
• Lower utility bills

3. Space Savings

• Compact wall-mounted units
• Free up floor space
• Install in closets or utility areas
• Multiple unit installation possible

4. Longer Lifespan

• 20+ years vs. 10-12 for tank heaters
• Replaceable parts extend life further
• Better long-term investment
• Fewer replacements over time

5. Clean, Fresh Water

• No tank rust or sediment
• Water doesn't sit in tank
• Healthier water quality
• Less maintenance needed

Drawbacks to Consider

1. Higher Upfront Cost

• Units cost $1,000-$3,000
• Installation: $500-$1,500
• May need gas line upgrade
• Electrical upgrades possible

2. Limited Flow Rate

• Measured in gallons per minute (GPM)
• Simultaneous use limitations
• May need multiple units for large homes
• Proper sizing critical

3. Installation Complexity

• Requires professional installation
• Gas line sizing important
• Venting requirements differ
• Altitude adjustments necessary

Tankless vs. Tank: Cost Comparison

Tank Water Heater

• Equipment: $400-$1,000
• Installation: $200-$500
• Annual energy cost: $300-$600
• Lifespan: 10-12 years
• Total 20-year cost: $10,000-$15,000

Tankless Water Heater

• Equipment: $1,000-$3,000
• Installation: $500-$1,500
• Annual energy cost: $200-$400
• Lifespan: 20+ years
• Total 20-year cost: $8,000-$12,000

Long-term savings: $2,000-$3,000

Santa Fe-Specific Considerations

High Altitude Impact

• Gas units need altitude adjustment
• Affects efficiency ratings
• Professional calibration required
• May reduce output slightly

Hard Water Challenges

• Mineral buildup concern
• Annual descaling recommended
• Water softener highly recommended
• Extends unit lifespan significantly

Cold Groundwater

• At 7,000 feet, groundwater is colder
• Affects output temperature
• Longer time to heat water
• May need larger unit than coastal areas

Adobe Homes

• Compact size ideal for limited space
• Easier retrofit than tank replacement
• Can install in accessible locations
• Multiple units for distant fixtures

Sizing a Tankless Water Heater

Determine Flow Rate Needed

Typical Flow Rates:

• Shower: 2.0-2.5 GPM
• Kitchen faucet: 1.5 GPM
• Dishwasher: 1.0-1.5 GPM
• Washing machine: 2.0 GPM
• Bathroom faucet: 0.5-1.0 GPM

Calculate Your Needs: Add GPM for simultaneous uses Example: 2 showers + kitchen faucet = 6 GPM minimum

Temperature Rise Required

Santa Fe groundwater: ~45-50°F Desired output: 120°F Temperature rise needed: 70-75°F

Unit Selection

• Small home (1-2 bath): 6-8 GPM unit
• Medium home (2-3 bath): 8-10 GPM unit
• Large home (3+ bath): 10+ GPM or multiple units

Gas vs. Electric Tankless

Gas Tankless (Recommended for Santa Fe)

Pros:

• Higher flow rates
• Works during power outages
• Lower operating costs
• Better for whole-house use

Cons:

• More complex installation
• Requires venting
• Gas line capacity needs
• Higher upfront cost

Electric Tankless

Pros:

• Lower equipment cost
• Simpler installation
• No venting required
• Good for point-of-use

Cons:

• Lower flow rates
• High electrical demands
• May need service upgrade
• Higher operating costs

Installation Requirements

Gas Units

• Adequate gas line size (3/4" or larger)
• Proper venting (direct vent or power vent)
• Combustion air supply
• Gas shutoff valve
• Altitude adjustment

Electric Units

• Sufficient electrical capacity (120-150 amps)
• Proper wire gauge
• Circuit breaker sizing
• GFCI protection where required

Both Types

• Adequate water pressure (40-80 PSI)
• Water shutoffs
• Drain valve for maintenance
• Professional installation required

Maintenance Requirements

Annual Service

• Flush system with vinegar
• Descale heat exchanger
• Check and clean filters
• Inspect venting (gas units)
• Test temperature and pressure
• Verify altitude settings

DIY Monthly Tasks

• Check for error codes
• Clean inlet filter screen
• Verify proper operation
• Monitor performance

Santa Fe Maintenance Needs

• More frequent descaling (hard water)
• Annual professional service recommended
• Water softener maintenance
• Winter freeze protection

Best Applications for Tankless

Ideal Scenarios

• New home construction
• Room additions
• Master suite remodels
