Why Choose a Tankless Water Heater?
Tankless water heaters work differently than traditional tank systems. Instead of storing heated water in a large tank, they heat water on-demand as it flows through the unit. This means several important benefits for your home:
Energy Efficiency: Tankless systems use 24-34% less energy than traditional tank heaters, according to the U.S. Department of Energy. That translates directly to lower utility bills month after month.
Space Savings: These compact units mount on your wall and take up a fraction of the space a traditional tank requires. If you’re short on space in your basement or utility room, a tankless system is ideal.
Endless Hot Water: You’ll never run out of hot water again. Whether you’re filling a bath, doing laundry, or showering while someone else washes dishes, tankless systems keep up with demand.
Longevity: With proper maintenance, tankless water heaters last 15-20 years—about 5 years longer than traditional tanks.
Lower Maintenance: These systems require less frequent maintenance and have fewer parts that can fail compared to tank models.

Our Tankless Water Heater Installation Process
We don’t just show up and install your system. Our process is thorough, professional, and designed to ensure your new tankless water heater performs perfectly from day one.
Step 1: Professional Assessment
We evaluate your current plumbing setup, water pressure, and hot water demands. This helps us recommend the right size and type of tankless system for your specific needs. An undersized unit will struggle to keep up; an oversized one wastes money.
Step 2: System Selection
We help you choose between gas and electric tankless heaters based on your home’s infrastructure and your budget. Gas units typically have higher flow rates, while electric models are often easier to install.
Step 3: Professional Installation
Our licensed plumbers handle all aspects of installation, including venting (for gas models), water line connections, and electrical work. We ensure everything meets local codes and manufacturer specifications.
Step 4: System Testing
Before we leave, we thoroughly test your new system to confirm proper operation, water temperature consistency, and safety features.
Step 5: Maintenance Guidance
We provide clear instructions on maintaining your system and schedule regular check-ups to keep it running efficiently.

Tankless Water Heater Repair Services
Even the best tankless systems occasionally need attention. We provide comprehensive water heater repair services to keep your system running smoothly. Common issues include mineral buildup, fluctuating water temperature, and reduced flow rate.
When you call Pike Plumbing for repair service, we diagnose the problem quickly and explain your options clearly. We stock parts for most major brands and can often complete repairs the same day.

Common Issues We Fix
Mineral Buildup: In areas with hard water, minerals accumulate inside your tankless unit, reducing efficiency. We perform descaling to remove buildup and restore performance.
Temperature Fluctuations: If your water temperature bounces between hot and cold, it might be a flow sensor issue or improper installation. We identify and fix the root cause.
Low Water Pressure: Sometimes the problem isn’t the heater itself—it’s your water lines or a faulty pressure valve. We investigate thoroughly.
Ignition Issues: Gas tankless heaters rely on precise ignition systems. We repair or replace ignition components as needed.
Venting Problems: Improper venting reduces efficiency and can create safety concerns. We inspect and correct venting issues.
Many of these issues can be prevented with proper maintenance. That’s why we recommend annual maintenance, such as descaling service and inspection.
We offer thermal expansion tank repair services as well.

- Check Water Filters: Replace inlet filters regularly to prevent debris from damaging internal components.

Call Us TodayFrequently Asked Questions
How much does tankless water heater installation cost?
Installation costs vary based on your home’s current setup, the type of unit you choose (gas or electric), and any necessary upgrades to venting or water lines. Gas tankless heaters typically cost more to install, while electric models can be a cheaper option.
We provide free estimates so you know the exact cost before we begin work. The energy savings usually pay back the investment within 5-7 years.
How long does tankless water heater installation take?
Most installations take 4-8 hours, depending on your home’s plumbing configuration and whether we need to upgrade water lines or venting. We’ll give you a specific timeframe during your consultation. We work efficiently to minimize disruption to your home while ensuring every connection meets code requirements.
What size tankless water heater do I need?
The right size depends on your household’s peak hot water demand—how many showers, appliances, and fixtures run simultaneously. We calculate this during our assessment and recommend a unit with the appropriate flow rate (measured in gallons per minute). Undersizing causes cold water to mix in, while oversizing wastes money. Our experts get this right so you have consistent hot water without overpaying.
