Benefits of Tankless Water Heaters
Endless Hot Water Supply
Never run out of hot water again! Tankless units heat water on demand as it flows through the system, providing continuous hot water for as long as you need it. Perfect for large families, back-to-back showers, or filling large soaking tubs.
Superior Energy Efficiency
Tankless water heaters are 24-34% more energy efficient than traditional tank models for households using 41 gallons or less of hot water daily, and 8-14% more efficient for households using around 86 gallons daily. No standby heat loss means lower utility bills and reduced environmental impact.
Space-Saving Compact Design
Wall-mounted tankless units are about the size of a suitcase, freeing up valuable floor space. Perfect for closets, utility rooms, or even outdoor installation (with proper weatherproofing). No bulky 40-80 gallon tank taking up room in your garage or basement.
Longer Lifespan
Tankless water heaters typically last 15-20+ years with proper maintenance, compared to 8-12 years for traditional tanks. Quality units with regular descaling can exceed 20 years, making them a smart long-term investment despite higher upfront costs.
Reduced Risk of Water Damage
With no storage tank, there's no risk of catastrophic tank failure flooding your home with 40-80 gallons of water. While tankless units can develop small leaks, they don't hold large volumes of water that can cause extensive damage.
Precise Temperature Control
Digital controls allow precise temperature settings, ensuring consistent water temperature without the fluctuations common in tank systems. Many models feature LCD displays and remote controls for easy adjustment.
Lower Long-Term Costs
While tankless units cost more upfront ($1,000-$3,000+ installed vs $800-$1,500 for tanks), energy savings of $100-$200+ annually, longer lifespan, and available rebates often result in lower total cost of ownership over the unit's lifetime.

Common Water Heater Diagnostic Tests
Our technicians use advanced diagnostic techniques to accurately identify water heater problems:
Temperature Testing
We measure water temperature at multiple points to verify your heater is producing water at the correct temperature (typically 120-140°F). Temperature inconsistencies can indicate thermostat problems, failing heating elements, or sediment buildup.
Pressure & Relief Valve Testing
We test the temperature and pressure relief (T&P) valve to ensure it's functioning correctly. This critical safety device prevents dangerous pressure buildup. A malfunctioning T&P valve requires immediate replacement.
Electrical System Testing
For electric water heaters, we test voltage, check heating element continuity with a multimeter, verify thermostat operation, inspect wiring for damage, and ensure proper grounding and electrical safety.
Gas System Inspection
For gas water heaters, we inspect the pilot light and thermocouple, test the gas valve, check for gas leaks, examine the burner assembly and flame pattern, and verify proper venting and combustion air supply.
Leak Detection
We thoroughly inspect all connections, valves, and the tank itself for signs of leaks. We check the drain valve, inlet/outlet connections, pressure relief valve, and tank seams. Even small leaks can indicate serious problems.
Anode Rod Inspection
We examine the sacrificial anode rod which protects your tank from corrosion. If the anode is heavily corroded or depleted, replacement is necessary to prevent tank failure. This simple maintenance can extend your water heater's life by years.
Sediment Analysis
Hard water causes mineral sediment to accumulate at the tank bottom. We assess sediment levels and recommend flushing if necessary. Excessive sediment reduces efficiency, causes noise, and shortens tank life.
Error Code Reading (Tankless)
Modern tankless water heaters display error codes when problems occur. Our technicians are trained to interpret these codes for all major brands and can quickly identify the specific issue requiring repair.
Emergency Water Heater Situations
Some water heater problems require immediate attention. Call us right away if you experience:
Active Water Leak or Flooding
If water is actively leaking from your water heater, turn off the water supply immediately. Shut off power (circuit breaker) for electric units or gas supply for gas units. Call us for emergency service. Leaking water can cause significant property damage and may indicate tank failure.
Gas Leak or Gas Smell
If you smell gas (rotten egg odor) near your water heater, evacuate your home immediately. Do not use electrical switches, phones, or anything that could create a spark. Once outside, call 911 and your gas company. Then contact us to schedule repair once the area has been declared safe.
Relief Valve Continuously Discharging
If the temperature and pressure relief valve is constantly releasing water or steam, this indicates dangerous pressure buildup. Turn off power/gas to the unit and call for emergency service. This is a serious safety hazard that requires immediate professional attention.
Scalding Hot Water
If your water temperature suddenly becomes dangerously hot (above 140°F), this indicates thermostat failure or control malfunction. Turn down the thermostat and call for service. Scalding water poses serious burn risk, especially for children and elderly.
Complete Loss of Hot Water in Winter
In cold weather, complete loss of hot water is an urgent situation. Frozen pipes can burst, and lack of hot water poses health and safety concerns. We prioritize these calls for same-day emergency service to restore your hot water quickly.
Preventive Water Heater Maintenance
Regular maintenance extends your water heater's lifespan and prevents costly emergency repairs. We recommend these maintenance tasks:
Annual Tank Flushing
Sediment accumulates in tank water heaters over time, especially in areas with hard water. We recommend annual flushing to remove sediment buildup. This simple maintenance improves efficiency, reduces noise, and extends tank life. For homes with very hard water, flushing twice per year may be beneficial.
Anode Rod Inspection & Replacement
The sacrificial anode rod protects your tank from corrosion. We recommend inspecting it every 2-3 years and replacing when heavily corroded. Replacing the anode rod is inexpensive (typically $150-$300) but can extend your water heater's life by 5-10 years, saving you thousands on premature replacement.
Temperature & Pressure Relief Valve Testing
The T&P valve is a critical safety device. Test it annually by lifting the lever and allowing water to discharge briefly. If water doesn't flow or the valve leaks after testing, replacement is needed. Never skip this important safety check.
Thermostat Calibration
Water heater thermostats can drift over time. We verify your water temperature matches thermostat settings (recommended 120°F for safety and efficiency). Proper temperature prevents scalding while providing adequate hot water and minimizing energy costs.
Tankless Descaling
Tankless water heaters require annual descaling to remove mineral buildup from the heat exchanger. We use professional descaling solutions to flush the system, maintaining efficiency and preventing damage. This maintenance is essential in hard water areas and typically takes 1-2 hours.
Connection & Valve Inspection
We inspect all water connections, gas lines (for gas heaters), electrical connections (for electric heaters), and shut-off valves for signs of wear, corrosion, or leaks. Early detection of small issues prevents major problems and water damage.
