Whenever you find that you’re not getting the same response from your water heater as you should be; you need to look at it urgently. There are several potential causes of reduced flow hot water.
It is worth noting that any water heater will only provide approximately two thirds of its capacity as hot water. For example if you have a 50 gallon tank you should expect 33 gallons of hot water.
1. Change in Plumbing
Even something as simple as changing the shower head can change the flow of water; if it increases the number of liters of water going through the pipes as you shower it will reduce the time your hot water will last.
Another common issue that reduces hot water flow is when you have a leak in your pipes. This is not always easy to find; especially if the leaking pip is within the walls.
You can shut off all your water appliances and then check your water meter. Re-check it 30 minutes later; if it’s moved then you have a leak.

3. Water Heater Issue
If you have debris in your pipes or sediment in your tank it can prevent your hot water heater from working properly. As the sediment builds up it is likely that this will make your heater work harder; you won’t notice the difference.
However, as your water heater ages it will become less able to heat the water; giving you less hot water.
The same reduced flow could also be present if one of the heating elements inside your hot water stops working; the remaining elements will not be able to heat the water as effectively.
4. Power Outage
If you’re using a tank water heater then it is possible that the thermostat has been set to low; or that the power has been interrupted. This will reduce the ability of the water heater to give you the hot water you need.
If this is a regular occurrence you may need to get a plumber to check for an electrical issue.
Equally, gas powered water heaters can be missing a dip tube which will reduce their ability to produce hot water for you.
Many people overlook the fact that the season plays a part in the temperature of your water. In the winter the water entering your house will be much colder than in the summer. Your water heater will need to work harder in order to get the water to the right temperature.
