Emergency Water Heater Information
Some water heater problems require faster attention than an ordinary loss of hot water. Active tank leaks, rapidly spreading water, relief-valve discharge, exposed electrical components, gas odors, smoke, combustion problems, steam, and extremely hot water may present immediate risks.
What to Do During a Water Heater Emergency
- Keep people and pets away from the affected area.
- Avoid standing water near electrical equipment.
- Do not touch damaged wiring, controls, gas components, or extremely hot pipes.
- If you smell gas, avoid switches and ignition sources and leave the property.
- Contact emergency services or the utility provider when there is an immediate danger.
- Request emergency water heater service as soon as it is safe to do so.
Do not rely on a website form, email, or voicemail to report a life-threatening emergency. These communication methods may not be monitored continuously.
Water Heater Repair Resources
Different symptoms can have similar causes. Professional troubleshooting helps distinguish between a failed component, installation problem, plumbing issue, electrical failure, gas-control problem, sediment buildup, or deteriorating tank.

Leaking Water Heater Repair
Water may escape from a connection, valve, drain component, relief valve, nearby pipe, or the tank itself. Finding the source is essential because a leaking tank generally requires replacement, while some external leaks may be repairable.

No-Hot-Water Diagnosis
A complete loss of hot water may involve a heating element, thermostat, breaker, wiring connection, igniter, burner, gas control, sensor, fuel supply, or system error.
Water Heater Component Repair
Depending on the system, repair may involve thermostats, heating elements, gas controls, igniters, burners, valves, electrical connections, sensors, or other replaceable parts.

Water Heater Replacement Resources
Replacement may be appropriate when a tank is leaking, corrosion is extensive, repairs are becoming frequent, parts are unavailable, capacity is inadequate, or restoration costs are no longer practical.
A replacement decision should consider:
- Equipment age and overall condition
- Location and accessibility
- Available fuel and utility capacity
- Household or building hot-water demand
- Tank versus tankless operation
- Energy efficiency
- Installation and code requirements
- Equipment and installation costs
- Warranty coverage
- Expected maintenance needs

Water Heater Installation Resources
Proper installation affects safety, efficiency, performance, warranty coverage, and equipment life. Installation requirements vary by equipment type, fuel source, property configuration, manufacturer instructions, and applicable building codes.
Installation planning may include:
- Water heater sizing and capacity
- Water and energy connections
- Gas supply or electrical requirements
- Venting and combustion-air requirements
- Drain pans and discharge piping
- Thermal expansion control
- Temperature and pressure relief protection
- Equipment clearances and accessibility
- Permits and required inspections
- Removal and disposal of old equipment

Compare Water Heater Types
Understanding the available technologies can make it easier to select equipment that fits the property, expected demand, installation conditions, and operating budget.
Tank Water Heaters
Traditional tank water heaters store a supply of heated water for use when needed. Important considerations include storage capacity, recovery rate, first-hour rating, fuel source, installation space, and standby energy loss.
Tankless Water Heaters
Tankless water heaters heat water as it flows through the system. Proper sizing depends on the required flow rate and temperature rise. Utility capacity, venting, water quality, and maintenance requirements should also be evaluated.
Explore tankless water heaters
Gas Water Heaters
Gas water heaters require suitable fuel delivery, burner operation, combustion air, venting, safety controls, and carbon-monoxide precautions.
Electric Water Heaters
Electric models commonly use thermostats and heating elements to heat stored water. Circuit capacity, wiring, overcurrent protection, grounding, and electrical safety are important installation and repair considerations.
Learn about electric water heaters
Heat-Pump Water Heaters
Heat-pump water heaters transfer heat from the surrounding air into stored water. They may reduce energy use in suitable installations but require adequate space, airflow, drainage, and appropriate operating conditions.
Explore heat-pump water heaters
Commercial Water Heaters
Commercial properties may require greater capacity, faster recovery, redundant equipment, specialized controls, recirculation, and service planning that minimizes operational interruptions.

Water Heater Maintenance Resources
Routine maintenance can help identify corrosion, leaks, sediment, worn components, and performance problems before they cause a major interruption. Maintenance needs depend on the equipment, manufacturer instructions, water quality, usage, and installation.
Depending on the system, maintenance may include:
- Checking accessible connections for leaks
- Inspecting for corrosion or moisture
- Reviewing temperature and system operation
- Checking accessible safety components
- Flushing loose sediment when appropriate
- Descaling a tankless heat exchanger
- Inspecting or replacing an anode rod
- Cleaning applicable filters or screens
- Checking burner or heating-element performance
- Reviewing manufacturer error codes

Request Professional Water Heater Help
Online resources can help you recognize warning signs, but they cannot confirm the condition of a specific water heater. If your system is leaking, producing inconsistent temperatures, making unusual noises, or no longer providing dependable hot water, professional troubleshooting can identify the cause and the appropriate next step.
