- No hot water or insufficient hot water – The most obvious sign something is wrong.
- Water temperature fluctuations – Hot water that comes and goes indicates a failing heating element or thermostat.
- Strange noises – Popping, rumbling, or banging sounds suggest sediment buildup in the tank.
- Rusty or discolored water – Brown or rusty hot water may indicate tank corrosion.
- Leaking around the base – Any water pooling around your water heater requires immediate attention.
- Rotten egg smell – A sulfur smell in hot water indicates bacterial growth in the tank.
- Age – If your water heater is over 10 years old, it may be time to consider replacement.
- Higher energy bills – An inefficient water heater works harder and costs more to operate.

Types of Water Heaters
Traditional Tank Water Heaters The most common type, tank water heaters store 30-80 gallons of hot water ready for use. We service both gas and electric models from all major manufacturers.
Pros: Lower upfront cost, simple technology, easy to repair Cons: Higher energy costs, limited hot water supply, larger footprint
Tankless Water Heaters Also called on-demand water heaters, these units heat water only when needed, providing endless hot water and energy savings.
Pros: Unlimited hot water, energy efficient, compact size, longer lifespan Cons: Higher upfront cost, may require electrical or gas upgrades
Heat Pump Water Heaters These energy-efficient units use electricity to move heat from the air to the water, using less energy than traditional electric water heaters.
Solar Water Heaters Using solar panels to heat water, these systems can significantly reduce energy costs in sunny climates.
Choosing the Right Water Heater Size
Selecting the proper size water heater is crucial for meeting your household’s hot water needs without wasting energy. Factors to consider include:
- Number of people in your household
- Number of bathrooms
- Peak hot water usage times
- Simultaneous hot water needs (multiple showers, dishwasher, laundry)
As a general guide:
- 1-2 people: 30-40 gallon tank
- 2-3 people: 40-50 gallon tank
- 3-4 people: 50-60 gallon tank
- 5+ people: 60-80 gallon tank or tankless
A qualified plumber can assess your specific needs and recommend the right size for your home.
Water Heater Maintenance Tips
Regular maintenance can extend the life of your water heater and improve efficiency:
- Flush the tank annually – Draining sediment from the tank prevents buildup and improves efficiency.
- Test the pressure relief valve – This safety device should be tested yearly to ensure proper operation.
- Check the anode rod – This sacrificial rod protects the tank from corrosion and should be replaced every 3-5 years.
- Insulate the tank – Adding insulation can reduce heat loss and lower energy costs.
- Set the right temperature – 120°F is recommended for safety and efficiency.
- Check for leaks – Regularly inspect connections and the base of the tank for moisture.
Emergency Water Heater Service
A leaking water heater is an emergency. A standard 50-gallon tank can flood your home with significant water damage if it fails. If you notice water pooling around your water heater:
- Turn off the power (electricity or gas)
- Turn off the cold water supply to the unit
- Call a local plumber immediately
