Lack of hot water can be annoying and frustrating. It can also lead to a plumbing emergency, especially if there are infants or elderly individuals residing in the household.
It is important to know the signs a hot water system is not working properly so you can prevent further damage, keep the members of your household safe, and avoid costly problems.
Here, we’ll cover 11 signs that a hot water system is not working properly so you know what to look for and what to do if you have no hot water.
What Are Some Common Types of Hot Water Systems?
A hot water system is typically composed of a heating element to warm the water when it enters the tank and an insulated tank for storing the heated water.
Hot water systems come in various types, including:
- Electric Hot Water Systems — Electric hot water systems heat water using electric resistance elements. This is a convenient option for areas lacking a supply of natural gas.
- Heat Pump Hot Water Systems — Heat pump hot water systems are considered an energy-efficient form of water heating. They work by capturing heat from the ground or air to heat your water.
- Solar Hot Water Systems — Solar hot water systems capture light from the sun using solar panels. This sunlight is then converted into usable energy that can heat the water.
- Tankless Water Heaters — Continuous flow or tankless water heaters produce hot water on demand, negating the need for a tank to store the hot water.
11 Indicators A Hot Water System Is Not Working Properly
Read on to learn 11 indicators your hot water system is not working properly and what to watch for.
1. Discoloured Water
If you notice discoloured or rusty water, it could be an indication that the interior portion of the tank is deteriorating or corroding. This likely indicates the system is failing and will need to be replaced.
2. Insufficient or Decreased Hot Water Supply
If you notice a significant reduction in the amount of hot water available, it could indicate a failing water heater. This can be caused by a malfunctioning heating element, sediment buildup, or other internal issues.
A complete lack of hot water is a clear indicator that your hot water system needs immediate attention. It may require repair or replacement and needs to be evaluated by a licensed plumbing professional as soon as possible.
3. Unusually High Energy Bills
Did your energy bills suddenly spike without explanation? A sudden, unexplained jump in your energy bills may indicate a failing water heater.
If there are signs of leaks or water pooling around your water heater, call an emergency plumber right away. Leaks require prompt attention to prevent significant damage or major repairs.
5. Sediment Buildup
The bottom of a water heater tank can accumulate sediment and debris over time. This build-up can reduce heating efficiency, create inconsistencies with your hot water, and potentially damage the tank.
6. Odd Noises
If you hear rumbling sounds or popping, banging, or other odd noises coming from your water heater, it may be a sign your water heater is failing or needs repair.
7. Fluctuating Water Temperatures
If you notice unexpected fluctuations in your water temperature, the thermostat or heating element may be failing. Contact an emergency plumber immediately to have it assessed and repaired if needed.
8. Solar Hot Water Systems
Certain hot water problems pertain to particular hot water systems. For instance, solar hot water systems are susceptible to failure or lack of efficiency during periods of low sunlight. Issues with the heat exchanger or solar panels can also lead to solar hot water system problems.

9. Tankless Water Heaters
If your tankless water heater is struggling to keep up with the hot water demand, it can lead to a total lack of hot water or fluctuating water temperatures.
10. Electric Hot Water Systems
Electric hot water system problems, such as insufficient heat or no hot water, can be a result of thermostat issues, a faulty heating element, or other internal problems that need immediate assessment.
11. Heat Pump Hot Water Systems
Strange noises, insufficient hot water, or decreased heating capacity can all indicate a problem with your heat pump hot water system.
What To Do If There’s No Hot Water?
If you aren’t getting hot water out of your taps, check to see if you get cold water. If your cold water is running fine, it indicates a hot water system-related problem. Call a plumber to have your hot water system assessed.
While some hot water system repairs are minor, hot water system problems are best left to a professional. There may be a problem with low water pressure, valves that aren’t fully open, issues with your home’s thermostat, or a power cut. Or there could be a leak that cannot be seen without advanced leak detection equipment.
