Imagine your water heater unit is completely fine and properly delivering hot water but you walk into the shower expecting warmth and you are hit with cold water. So this is the most frustrating and confusing situation. Why is your water heater working but no hot water coming out?
We know how much you crave for hot, cozy water in winters but the biggest issue is that even if your system is working properly but not heating properly leads from small glitches to a complex component failure. In this guide MileHi HVAC explains every breakdown and how issues can be resolved quickly and efficiently.
Reasons Behind Why Your Water Heater Works But Doesn’t Heat
Before discussing the solutions it is important to understand what’s happening when you have a water heater working but no hot water. This situation means that your system is receiving power and working properly but there is some issue in the heating system. There are several reasons behind it like sediment builtup, thermostat issues and ignition failures.
Common Reasons For No Hot Water
Let’s discuss what are the causes behind this and how quickly and efficiently they can be fixed.
Pilot Light Is Out
If you have a gas water heater then the problem may be in the pilot light. If the pilot light is on and no hot water then it is clear that this is the culprit. Because even when pilot light is on due to dust in the burner and faulty thermocouple prevent firing up.
Try to light up the pilot light according to the instructions if it is not working even then it means it is time to call professionals for help like MileHi HVAC.
Thermostat Malfunction
The main purpose of the thermostat is to maintain water temperature. If your thermostat is faulty then it creates hot water problems for you. This is due to several reasons like sometimes setting turns low or with the age thermostat fails.
First check your water settings ideally around 120F. If the issue is not resolved even after that it means you have to replace the thermostat with the help of experts.
Electric Units Failure
Your electric water heater works on two elements. If there is an issue in one then the other also stops working like one unit may power on but still fail to provide heat.
In this case turn off the power and check units through the multimeter if there is an issue then it needs replacement. Contact MileHi HVAC so that our experts replace your system safely and in a reliable way.
Sediment Buildup
Due to hard water and with passage of time several chemicals and dust build up in the bottom of tanks which affects the working of system like issues in heating system efficiency. This buildup leads to hot water problems.
Flushing your water heater once a year not only cleans the sediment buildup but extends the lifespan of your system. If your gas water heater is not working properly after pro[er maintenance then it requires a professional checkup.
Gas Supply
If you own a gas water heater then the primary source of working heater is supply of gas. If your pilot light is on but no hot water it means there is some disturbance in gas supply. Due to dust and corrosion the gas flow to the burner is affected.
Never try to check the gas valve on your own because it is very risky. Contact some professionals which are skilled in this area for assistance.
