No hot water in shower but sinks are ok
If you’re experiencing no hot water in your shower but have hot water in your sinks, it’s likely that the issue is localised to your shower system.
In this case, the potential causes can include a malfunctioning shower mixing valve, improperly set anti-scald device settings, or cross-connected pipes. Let’s explore each of these possibilities in more detail, so you can identify and resolve your cold shower conundrum.
Understanding how the shower mixing valve, anti-scald device settings, and cross-connected pipes regulate water temperature equips you with the knowledge needed to troubleshoot and rectify the issue.
This leads to a more comfortable shower experience with an ideal balance of hot and cold water.
Inspect the Shower Mixing Valve
The shower mixing valve is instrumental in achieving the ideal shower temperature by merging hot and cold water. If the valve is malfunctioning, it may be the cause of cold water in your shower.
Worn-out washers or O-rings in the shower valve can also result in cold water coming through the showerhead, even when the valve is turned to ‘hot’.
If a mixing valve issue arises, inspecting, repairing, or replacing the valve becomes necessary. This may involve replacing the rubber parts, such as O-rings, or the entire mixing valve.
While some minor repairs can be done by a handy homeowner, it’s generally recommended to entrust more complex repairs to a professional plumber.

Evaluate the Anti-Scald Device Settings
Anti-scald devices are designed to regulate water temperature and prevent excessively hot or cold water from causing discomfort or injury.
If the device settings are set too high, it can result in a lack of hot water in the shower. To adjust the settings, you can turn the device to the right and test the water. Continue adjusting until you achieve the desired temperature.
Correctly installing and setting your shower’s anti-scald device is necessary for maintaining both comfort and safety.
In households with elderly individuals and children, having a properly adjusted anti-scald device can help prevent accidental scalding and provide a more enjoyable shower experience.
Check for Cross Connected Pipes
Cross-connected pipes were frequently used in older properties to balance the flow of hot and cold water. This design was common prior to modern methods of plumbing being readily available.
If you have cross-connected pipes and notice that the hand shower heats up when the main shower head is switched off, the issue is likely related to the pipes. Signs of cross-connected pipes can include:
- Varying water temperature in different fixtures
- Fluctuating water pressure
- Peculiar noises in the plumbing system
- Discolored or foul-smelling water
Should you suspect that cross-connected pipes are causing your cold showers, seeking professional assistance is recommended.
A plumber can inspect your plumbing system, identify any cross-connected pipes, and make the necessary repairs to restore an adequate hot water supply to your shower.

No hot water in shower or taps
If you’re experiencing a lack of hot water in both the shower and taps, it’s likely that the issue extends beyond just the shower system. In this case, the potential causes can include:
- A disrupted gas supply
- A malfunctioning boiler
- Sediment build-up in the water tank
We will examine each of these possibilities of no hot water to taps at all and how to tackle them.
Understanding the wider scope of hot water issues affecting both the shower and taps can help you identify the root cause and take appropriate action to restore hot water to your entire home.
Check your gas supply to the house
Your house’s gas supply is instrumental in maintaining a steady hot water supply. If there’s a disruption in the gas supply, it can directly impact the availability of hot water in your shower and taps.
To ensure the gas supply is functioning effectively, you may need to inspect the gas line for any obstructions or issues, and request an independent test of your gas meter from your energy supplier to ensure its accuracy.
If you suspect a disruption in the gas supply, it’s best to contact a professional plumber for assistance. They can help identify and resolve the issue, ensuring a reliable and uninterrupted supply of hot water to your home.
Check your boiler is working
A fully operational boiler is necessary to supply hot water to your entire home. If your boiler is not working correctly, it can directly impact the hot water supply to your shower and taps.
To check if your boiler is working correctly, you can inspect its performance, pilot light, and relevant settings.
Some combi boilers are best for showers when there is just one running, but if you find that your boiler is not functioning correctly, it’s best to seek professional help to address the issue.
A plumber or technician can diagnose the problem, make necessary repairs, and ensure your boiler is operating efficiently to provide a consistent hot water supply to your home.

Investigate for Sediment Build-Up
Sediment build-up in your water tank can cause a range of issues, including:
- Reduced hot water supply
- Accumulated debris, corrosion, and solid material settling at the bottom of the tank
- Damage to the interior of the tank
- Reduced lifespan of the tank
Flushing the tank and removing any accumulated debris is required to tackle sediment build-up. This can help restore the tank’s performance and ensure a consistent hot water supply to your shower and taps.
If you’re unsure about how to flush the tank, it’s best to consult with a professional plumber for guidance and assistance.
Test Other Taps for Hot Water Supply
Testing other faucets in your home can help you determine if the hot water issue is isolated to the shower or affecting the entire house. Here’s what you can do:
- Turn on the hot water taps in other sinks, showers, or bathtubs.
- Observe if they are also experiencing a lack of hot water.
- If all the faucets have no hot water, then the issue is likely affecting the entire house.
Comparing the hot water supply in different faucets helps you identify the underlying issue and take the necessary action.
Whether the problem is confined to a single faucet or affecting the entire house, knowing the extent of the issue is essential for effective troubleshooting and resolution.
Consider the Age and Condition of Your Water Tank
The age and condition of your hot water heater can significantly impact the hot water supply in your home.
On average, a water heater tank should be replaced every 8 to 12 years.
As the tank ages, it may become less effective in heating water, leading to reduced performance and a lack of hot water.
If your water tank is approaching its lifespan’s end or showing damage signs, contemplating a replacement could be beneficial.
A new, modern water tank can ensure a consistent and reliable hot water supply to your shower and taps, providing you with the comfort and convenience you deserve.

Could It Be the Pipes to The Shower?
Pipe-related issues, such as frozen pipes or corrosion, can cause a lack of hot water in the shower. When faced with such issues, it’s important to identify the cause and take appropriate action to address the problem.
In the sections below, we’ll explore the impact of frozen pipes and corrosion on hot water supply and provide guidance on how to resolve these issues.
Understanding how the hot water feed pipe supplies hot water to your shower allows you to effectively troubleshoot and rectify any pipe-related issues, guaranteeing a consistent and enjoyable shower experience.
Look Out for Frozen Pipes
Frozen pipes can prevent hot water from reaching your shower, leading to a lack of hot water. When temperatures drop, the water inside pipes can freeze, expanding and placing pressure on the pipes, potentially causing them to crack or burst.
If you think frozen pipes are causing your cold shower, thawing the pipes to restore the cold and hot water supply is important.
This may involve applying heat, such as using a hairdryer or space heater, to gradually warm the affected pipes.
A frozen condensate pipe can also stop your boiler from working altogether, so if this is the case you need to defrost this too.
Always exercise caution when thawing pipes, and if you’re unsure about the process, it’s best to seek professional assistance.
Identify Corrosion or Obstructions
Corrosion or obstructions in pipes can reduce water pressure and affect hot water supply in your shower.
Clogging or obstruction of the pipes due to corrosion can cause a decrease in water pressure or a complete lack of hot water.
If you think pipe corrosion or obstructions are causing your shower’s hot water shortage, calling a professional plumber for assistance is important.
They can inspect your plumbing system, identify any issues, and make the necessary repairs to restore consistent hot water supply to your shower.

Lifestyle Factors and Timing
Lifestyle factors and timing can also impact hot water availability in the shower.
In busy households, appliance usage and peak demand times can influence the availability of hot water, leaving you with a less-than-satisfactory shower experience.
In the sections below, we’ll discuss strategies for managing hot water resources in a busy household and how to schedule showers to ensure hot water is available when needed.
Taking into account the impact of lifestyle factors and timing on your hot water supply allows you to adjust your routine and household habits to ensure a consistently enjoyable shower experience.
High Demand Times in a Busy Household
During peak times of demand in a busy household, the hot water supply can be affected depending on what type of boiler system you have, resulting in a lack of hot water for showers.
To avoid this issue, consider scheduling showers to avoid peak times, such as early mornings or late evenings when multiple family members may be using hot water simultaneously.
This is more related to system boilers with a tank, and all the water gets used up.
By adjusting your shower routine and being aware of your household’s hot water usage, you can maintain a consistent hot water supply for your showers.
This can lead to a more comfortable and enjoyable shower experience for everyone in the home.
Scheduling Showers Around Appliance Use
Scheduling showers around appliance use can also help ensure hot water is available when needed.
Appliances such as dishwashers and washing machines can consume a significant amount of hot water, potentially reducing the available supply for showers.
To optimise appliance use and ensure a consistent hot water supply for showers, consider the following:
- Use hot water appliances one at a time.
- Allow sufficient time between showers and appliance use to enable the water supply to reheat.
- Give priority to your shower’s hot water supply and avoid the concurrent operation of other hot water-consuming appliances.
By following these steps and ensuring the proper functioning of your dip tube in your electric water heater, you can ensure a continuous supply of shower water, providing all the hot water for your showers.
