All Pro Cooling, Heating, Plumbing & Electrical is proud to serve Ontario and surrounding Inland Empire communities with trusted home comfort services. One of the most common questions homeowners ask us is: “Should I upgrade to a tankless water heater, or stick with a traditional tank system?”
Both types of water heaters have advantages and drawbacks, and the right choice depends on your household size, water usage, and long-term goals. With rising energy costs and California’s focus on efficiency, now is the perfect time for Inland Empire homeowners to weigh the benefits of tankless vs. traditional water heaters.
How Traditional Water Heaters Work
Traditional water heaters use a large tank (usually 40–80 gallons) to store hot water.
- When you open a tap, the system draws from the pre-heated supply.
- Once hot water runs out, the tank refills and reheats.
Pros of Traditional Water Heaters:
- Lower upfront cost.
- Simple installation.
- Works well for households with steady, predictable hot water use.
Cons:
- Limited hot water supply (tank can run out).
- Higher utility bills due to “standby heat loss.”
- Larger footprint, taking up space in garages or utility rooms.
- Typically lasts 10–15 years.
How Tankless Water Heaters Work
Tankless systems (also called on-demand heaters) heat water instantly as it flows through the unit.
- No storage tank needed.
- Hot water never “runs out,” as long as the system is properly sized.
Pros of Tankless Water Heaters:
- Endless hot water supply.
- Smaller, space-saving design.
- 20+ year lifespan with proper maintenance.
- Lower monthly energy costs (no standby heating).
- Great for large families, luxury bathrooms, or frequent hot water use.
Cons:
- Higher upfront installation cost.
- May require panel or gas line upgrades.
- Can struggle if undersized for household demand.
Comparing Tank vs. Tankless
| Feature | Traditional Tank | Tankless (On-Demand) |
| Upfront Cost | Lower | Higher |
| Lifespan | 10–15 years | 20+ years |
| Hot Water Supply | Limited to tank size | Endless (properly sized) |
| Efficiency | Lower (standby loss) | Higher (on-demand heating) |
| Space Requirement | Large tank (garage/closet) | Compact, wall-mounted |
| Best For | Budget-conscious families | Efficiency seekers, luxury users |
Real-World Example: Riverside Home Upgrade
A Riverside family with four kids frequently ran out of hot water during busy mornings. After consulting with All Pro Cooling, Heating, Plumbing & Electrical, they decided to replace their 50-gallon tank heater with a tankless system.
Our team:
- Upgraded their gas line for proper system support.
- Installed a high-efficiency tankless water heater.
- Integrated it with a recirculation system to deliver hot water instantly at every tap.
The family now enjoys endless showers, lower energy bills, and a system built to last decades.
Local Relevance: Why This Decision Matters in the Inland Empire
- Hot Summers: Showers and laundry demand spike, straining tank systems.
- Older Homes in San Bernardino & Riverside: Many still rely on outdated tank heaters.
- Water Efficiency Rebates: Tankless systems often qualify for incentives.
- Space Savings: Tankless models free up garage or closet space in smaller Ontario homes.
Rebates & Incentives for Water Heaters
- SoCalGas Rebates: Up to $500 for high-efficiency tankless models.
- Local Water Agencies: Incentives for water-saving fixtures and appliances.
- Federal Tax Credits: Energy-efficient upgrades may qualify for credits.
These programs help offset the higher upfront cost of tankless systems.
Mistakes to Avoid
- Undersizing a Tankless Heater: Always size for peak demand.
- DIY Installation: Gas lines, venting, and electrical upgrades require licensed professionals.
- Ignoring Maintenance: Both tank and tankless systems require flushing to prevent sediment buildup.
- Focusing Only on Price: Consider long-term savings and performance, not just upfront cost.
How to Decide What’s Right for Your Home
- Household Size: Larger families benefit from endless hot water. Smaller households may do fine with a tank.
- Usage Patterns: If multiple showers, laundry, and dishwashing often overlap, tankless is worth it.
- Budget: Tanks are cheaper upfront; tankless saves more long-term.
- Future Plans: If you’re remodeling or upgrading plumbing, tankless may be the smarter choice.
