The Bay Area Air Quality Management District is phasing out gas appliances, so it’s important to understand why you’re not getting enough hot water to avoid a full replacement. A reliable supply of hot water is important for tasks like cleaning, cooking, and bathing. The highly skilled plumbers at Service Champions have some common reasons why your home water heater might not produce enough hot water, and what you can do to fix it.
If you're having hot water issues in your Bay Area home, there are many reasons why water heater problems shouldn’t be ignored:
If you have hard water, excess minerals build up at the bottom of the tank near the burner. Too much sediment prevents heat from the burner from reaching the water supply, impacting energy efficiency and limiting your access to hot water. One of the best ways to eliminate this problem is by draining your tank once a year and scheduling professional water heater maintenance annually.
A water heater not heating the water could have an issue with the thermostat, which may stop telling it to turn on once it thinks the water is hot enough. Raising the thermostat temperature helps to make the water feel hotter, but only if the thermostat is still functioning. Another potential solution is to install a thermostatic mixing valve or anti-scald valve, which mixes cold and hot water as it comes out of your tank to regulate the temperature better and prevent scalding.
If your electric water heater is not heating the water, it could be due to a failing heating element. Electric water heaters use upper and lower heating elements to heat the water supply, but if one or both fail, you won’t get reliable hot water. If your hot water runs out fast, it could be one failing heating element. If you have no hot water at all, both elements may have failed and will need to be replaced.
A water heater that is not heating water properly could simply be too small to meet household demand. When the water heater is undersized, it can’t produce hot water fast enough to handle several activities at once, causing the hot water to run out quickly. If you’re moving into a new home and want to upgrade or you plan to replace an existing water heater yourself, consult the highly trained plumbers at Service Champions to make sure you get the correctly sized unit for your home.
A water heater that’s not producing enough hot water may be too old to keep up with the demands of today’s modern appliances and lifestyles. Most water heaters last between eight and 12 years with proper maintenance, so if yours is nearing the end of its lifespan, it probably can’t keep pace. Worn anode rods, aging heating elements, and older thermostats all cause your gas or electric heater to stop making enough hot water.
Water heater recovery time refers to how many gallons your water heater can heat in one hour. Most gas water heaters have a recovery time of approximately 30 to 40 minutes, and most electric models take around 60 to 90 minutes. Tankless models don’t have a recovery time since they provide an instant supply of hot water as it flows through your plumbing.
One way to ensure reliable hot water availability is to know your specific water heater’s recovery time and to plan laundry, dishes, or showers around other household hot water needs. During normal household use, your hot water should last around 10 to 20 minutes in the shower for smaller water heaters, and between 15 and 20 minutes or longer for larger water heaters.
If you want a never-ending supply of hot water, consider upgrading to a tankless water heater. Instead of storing hot water in a tank, tankless units heat the water directly as it moves through the unit. Not only do these modern water heaters save space, but they also save a significant amount of energy. In terms of lifespan, traditional tank water heaters last approximately 10 years, while tankless water heaters last around 15 to 20 years or even longer with proper routine maintenance.
Routine professional maintenance, including a comprehensive inspection, water heater troubleshooting, and water heater repair when needed, is one of the best ways to support hot water performance. You should have your water heater professionally maintained once per year for peace of mind. Follow these simple maintenance tips to help you get a reliable supply of hot water year-round:
Why does your hot water run out so fast? You may wonder whether you need a repair or a full replacement. Signs of a failing water heater include major leaks, visible corrosion, unusually loud noises, and a complete lack of hot water. You should replace your water heater if it’s approaching the 10-year mark, or if you’re paying for frequent repairs that cost 50% or more of the cost of a new water heater. If your hot water becomes inconsistent, contact Service Champions to schedule an inspection and repair.
