Tankless Water Heater Repair & Replacement
Tankless water heaters – sometimes called on-demand water heaters – are a modern, energy-efficient alternative to traditional tank models. Instead of storing and reheating gallons of water, they heat water instantly as it flows through the unit.
That means you’ll never “run out” of hot water, making them a favorite for busy households, large families, and anyone who values efficiency.
However, while they require less maintenance than traditional tanks, they still need expert care. Mineral buildup, faulty sensors, or ignition problems can interrupt performance – and that’s where Victory Plumbing’s tankless expertise comes in.
What Is a Tankless Water Heater and Why It Matters
A tankless water heater consists of:
- A heat exchanger (powered by gas burners or electric elements)
- Flow sensors to detect water movement
- Electronic controls to regulate temperature and operation
Why it matters:
- Endless hot water: Perfect for households with high hot water demand.
- Energy savings: No standby heat loss like tank systems.
- Space savings: Wall-mounted design frees up floor space.
- Longer lifespan: Can last 5 – 10 years longer than traditional models with proper care.
Common Causes of Tankless Water Heater Problems
Even the most advanced units can run into trouble if not properly installed or maintained. Common causes include:
- Hard water mineral buildup: Reduces efficiency and can damage internal components.
- Blocked venting or air supply: Prevents combustion in gas units.
- Ignition failure: Often caused by faulty sensors or gas supply issues.
- Cold water sandwich effect: A brief burst of cold water between hot cycles.
- Overloaded system: Trying to run too many fixtures at once for the unit’s capacity.
- Improper installation: Incorrect venting, gas line sizing, or electrical setup.
Signs You May Need Tankless Water Heater Repairs or Replacement
Watch for these warning signs:
- Fluctuating water temperature during showers or dishwashing
- Error codes displayed on the unit’s control panel
- Low hot water pressure
- Strange noises (clicking, rumbling, or humming)
- Discolored or foul-smelling water
- No hot water at all despite the unit being powered on
- Age over 15 years with frequent repairs
