How Your Water Heater Makes Hot Water

Gas Water Heaters

Most gas water heaters use a burner at the bottom of the tank. A thermostat senses the water temperature and signals the gas valve to open. An igniter or pilot flame lights the gas, heating the water. Safety devices such as a thermocouple or flame sensor confirm the flame. Exhaust gases vent through a flue. If anything in this chain fails, you may have no hot water.

Electric Water Heaters

Electric models heat water with one or two electric elements controlled by upper and lower thermostats. Power must be present, and a high limit safety switch protects against overheating. A tripped breaker, a tripped high limit reset, or a failed element or thermostat can stop hot water production.

Tankless Water Heaters

Tankless units heat water on demand using gas burners or electric elements. They use flow sensors, temperature sensors, and complex controls. Hard water scale, undersized gas supply, blocked intake or exhaust, and winter conditions can trigger error codes and prevent heating. If you have a tankless system with no hot water Racine residents see most often in January, check for frozen vents or iced condensate drains.

Safety First

  • If you smell gas, hear hissing, or feel dizzy, leave the area and call your gas utility and a licensed plumber. Do not relight anything.
  • If you see water pooling near the heater or the temperature and pressure relief valve is discharging steadily, shut off the cold water supply to the heater and call for service.
  • Never remove covers or panels unless the manufacturer allows owner access. Turn off power at the breaker before touching an electric heater.
  • Keep kids and pets away from the heater while you troubleshoot.

7 Quick Checks You Can Do Before Calling a Plumber

1. Is It the Whole House or One Fixture?

Determine if the issue affects your entire home or only one tap. If other faucets deliver hot water, the problem may be a local mixing valve, shower cartridge, or a failed anti-scald device at that fixture. This is common after recent work or when debris clogs a cartridge.

  1. Try the kitchen sink, a bathroom sink, and a tub.
  2. If only one location is cold, check its handle settings and any under-sink shutoff valves.
  3. If the shower goes cold but other taps are hot, the shower mixing valve may need repair or replacement.

2. Did You Simply Run Out of Hot Water?

After back-to-back showers, laundry cycles, or a long dishwasher run, the tank may be depleted. Recovery time depends on tank size, input, and incoming water temperature. In winter, Racine’s cold groundwater slows recovery.

  1. Wait 30 to 60 minutes for a gas heater or 60 to 90 minutes for an electric heater to reheat.
  2. Limit hot water use during recovery to speed the process.
  3. If this happens often, your family may need a larger tank, a higher recovery model, or a hybrid or tankless upgrade. Northern Mechanical can size a system that matches your household.

3. Check Electrical Power and Breakers

Loss of power is a frequent cause of no hot water on electric tanks and some tankless units. A tripped breaker can occur after storms or when multiple appliances run at once.

  1. Locate your electrical panel and find the water heater breaker. It is usually double-pole for electric tanks.
  2. If tripped, switch it fully to OFF, then back to ON. If it trips again, stop and call a professional.
  3. For electric tanks, remove the upper access panel only if the manual allows, and press the red high limit reset button. Restore power and wait for heating. Use caution and turn power off first.
  4. Tankless units often have a power plug or service switch. Confirm it is on, then check for any displayed error code.

4. Confirm Gas Supply and Ignition

For gas water heaters, a closed gas valve, extinguished pilot, or failed igniter will stop heating. Construction, meter work, or a bumped valve can cause this.

  1. Make sure the gas shutoff valve on the heater’s gas line is parallel to the pipe. If it is perpendicular, it is closed.
  2. Look for a status light or code on the gas control. A steady blink often means normal operation. No light or rapid blinking may indicate a fault.
  3. If your model uses a standing pilot, follow the manufacturer’s relight instructions on the label. Do not attempt if you smell gas or feel unsafe.
  4. For electronic ignition, listen for a click or see a spark. If you have repeated ignition attempts without flame, call Northern Mechanical for service.

5. Inspect Thermostat Settings and Temperature

Thermostats set too low will feel like no hot water. An accidental bump during cleaning or moving items can change the setting. The Department of Energy recommends 120 degrees Fahrenheit for most homes.

  1. Check the dial on the gas control or the electronic display. Set it to 120 to 125 degrees.
  2. If you have an electric tank, verify both upper and lower thermostats are set to the same temperature. If you are not comfortable with this, call a pro.
  3. Be patient. Increasing the set point will not produce instant hot water. Allow time for the tank to heat.

6. Look for Closed Valves, Leaks, or Relief Valve Issues

A closed cold water inlet valve stops water from entering the tank. Without flow into the tank, your hot taps will quickly go cold. Leaks can also drop temperature and pressure, while a stuck mixing valve can cool hot water.

  1. Find the cold water shutoff above the heater on the right side pipe. It should be fully open.
  2. Inspect around the base of the tank for water. Also look at connections on top of the heater.
  3. Check the temperature and pressure relief valve discharge pipe. If it is dripping steadily, the system may be overheating, over-pressurized, or missing an expansion tank. Call a licensed plumber.
  4. If your home has a whole-home mixing valve, verify its setting and look for a failure sign such as lukewarm water at every faucet.

7. Review Error Codes and Cold-Weather Problems

Modern heaters display diagnostic codes. In Racine winters, venting and condensate lines can freeze or clog. Tankless units are especially sensitive to these issues.

  1. Read the display or the blinking code on the control. Check the label on the heater or the owner’s manual for code meaning.
  2. For high-efficiency gas and tankless units, inspect the outdoor intake and exhaust terminals. Clear snow, ice, and debris.
  3. Look for a frozen or kinked condensate drain line. If frozen, thaw gently and call for service to prevent refreezing.
  4. If you cannot clear the fault or the code returns, contact Northern Mechanical for professional diagnostics.

When to Call a Licensed Plumber in Racine

Some symptoms point to issues that require immediate professional help. Do not delay if you notice any of the following. A prompt fix can prevent water damage, carbon monoxide risks, or electrical hazards.

  • Gas smell, high carbon monoxide alarm, or persistent ignition failure
  • Breaker that trips again after reset on an electric heater
  • Visible leaks from the tank or fittings, or rusty water from hot taps
  • Age of tank over 10 years, or 15 years for tankless, with frequent problems
  • Error codes you cannot clear or that come back quickly
  • Relief valve discharge or rumbling, popping noises that suggest severe sediment

Preventive Tips to Avoid No Hot Water Next Time

For Traditional Tank Water Heaters

  • Flush the tank annually to reduce sediment that insulates the water from the burner or element. Sediment is common in Southeastern Wisconsin and can cause noise and slow recovery.
  • Inspect and replace the anode rod every two to five years to protect the tank from corrosion.
  • Test the temperature and pressure relief valve yearly for safe operation.
  • Set the thermostat to 120 degrees to balance comfort, safety, and energy use.
  • Add an insulation blanket and pipe insulation if the heater is in a cold space, following manufacturer guidance.
  • Install or service a thermal expansion tank if required by local code and your plumbing setup.

For Tankless Water Heaters

  • Descale the heat exchanger annually or as recommended, especially with hard water. A vinegar or approved cleaning solution flush helps maintain efficiency.
  • Clean inlet screens and water filters to maintain flow.
  • Ensure proper combustion air and clear venting. Keep outdoor terminations free of snow and ice.
  • Verify the gas line size and supply pressure meet manufacturer specifications to avoid ignition faults.
  • Consider a water softener or conditioner if scale builds up quickly.

For the Whole Home

  • Schedule annual maintenance with Northern Mechanical to catch small issues before they become failures.
  • Test your water quality. Hard or aggressive water can reduce heater life and efficiency.
  • Install a recirculation system if long waits for hot water waste time and energy.
  • Right-size your water heater when your family grows or usage patterns change. We can guide you to a properly sized tank, high-recovery model, hybrid heat pump heater, or tankless system.

Common Questions From Racine Homeowners

How long should it take for hot water to recover?

A typical 40 to 50 gallon gas tank takes about 30 to 60 minutes to recover after full use. Electric models often need 60 to 90 minutes. In winter, cold incoming water increases recovery time. If recovery is always slow, consider a higher BTU gas model, a second heater, or a hybrid or tankless upgrade. Northern Mechanical can evaluate your home and recommend the best option.

What temperature should I set my water heater to?

Most homes are well served at 120 degrees Fahrenheit. This reduces scald risk and saves energy while providing comfortable showers. If your dishwasher lacks an internal heater, you may set the tank to 130 degrees, but use anti-scald devices at fixtures and be cautious with children and older adults.

Is replacing my old water heater worth it?

Newer models are more efficient and reliable. Look for high Uniform Energy Factor ratings for tanks or condensing designs for gas units. Heat pump water heaters can save significant energy if installed correctly. In Southeastern Wisconsin, placement and ducting matter for heat pump units. Northern Mechanical can help you compare lifetime costs and choose a model that fits your utility rates, space, and usage.

Do I need a permit for a new water heater?

In Racine and most nearby municipalities, permits are required for replacements. Proper venting, expansion control, seismic strapping where required, and gas piping sizing are checked. Northern Mechanical handles permits, code compliance, and inspections so your installation is safe and legal.
