Imagine turning on your shower or sink and finding out that your hot water is not working properly. Could it get any worse? Probably not. The water heater is among the essential home appliances that are used on a daily basis. As it’s used on a daily basis, it’s highly unusual for the problem to form. Even in case of these problems, one can easily repair the water heater without any professional help but only if these problems are ignored for a long time. That said, here are some of the most common reasons why you have no hot water and their solutions as well. 

1. Tank Leakage

One of the most common causes of having no heated water at the time of need is the leaking tank. The water heater can only work if there is water available in the tank. That’s why the water tank and its connections should be the first thing to be inspected when facing a hot water problem. There are good chances that your tank’s compartment is leaking. In case you detect any leakeage in the water tank, fill the place those crack or replace it the tank. 

2. Leaking Gas

Gas leaking from your water heater can also be a dangerous cause of no hot water problem. Unfortunately, sometimes there are minor gas leakages in the house that remains unnoticed and later become the causes of huge trouble. That’s why it’s recommended to call the gas company’s professional and get your gas pipes and water heater inspected once in a while. 

3. Heater Malfunctioning 

It’s very common for electric appliances to malfunction. For example, electric heaters entirely rely on electricity and consist of a circuit breaker in it. If you have an electric heater installed at your home and facing no hot water issue, the first thing you should do is turn the electric heater off and rest the circuit breaker. If there was a breaker tripping problem, you’d regain the hot water supply in an hour. However, if you keep facing the tripping problem, it’s alarming, and you should consult an electrician to check your water heater. 

4. Damaged Pressure Relief Valve

The majority of the water heaters use a pressure relief valve. The purpose of this valve is to discharge the excessive pressure from the water tank. In the case of a damaged pressure relief valve, it can also cause hot water problems. If you’re facing this issue, order a new pressure relief valve and replace it. The valve installation process is very easy. 

5. Thermostat Malfunction 

The ideal temperature of the water heater to supply hot water while being energy efficient is between 120-140 degrees Fahrenheit. If you’re facing a hot water supply problem, you must check an upper thermostat. In case if you find the thermostat busted, make sure to replace it. Also, a lack of routine maintenance can cause issues like sediment buildup. In order to fix this, you need to flush the water heater. 

6. Small Tank Size

If your hot water consumption is more than the size of your hot water tank, then you’re very likely to face hot water supply and energy efficiency issues. That means the water heater is working just fine, and the problem lies in the tank size. For that, you need to upgrade to a larger hot water tank. When upgrading your hot water tank, you should keep in mind that an electric heater takes more time to heat the water as compared to a gas heater. 

7. Weather Conditions 

The temperature of water in your hot water tanks is also affected directly by external weather conditions, and so does the water heater’s energy efficiency. If you live in the Southwest region, you are more likely to face performance issues in your water heater during winters. To fix that, you need to adjust the thermostat temperature according to the weather condition of your area. 

8. Discolored Water 

The hot water coming out of the water tank should be clear. In case you see discolored water, it’s a sign of a water tank or the anode rod of your heater’s deterioration. The good news is, it’s completely fixable if you notice this issue in the early phases. Just contact a professional plumber to get the anode rode replaced properly. However, if this issue is left unattended, the rust can spread inside the hot water tank and begin to form small cracks. These cracks would result in water leakages on the floor and furniture of your home. So, it’s recommended to get this issue fixed as soon as possible in order to save money and time. 

9. Low Water Pressure 

Low water pressure can also be a possible cause that your hot working is not working. People usually blame low water pressure on water heater malfunctioning, but it’s not always true. For example, if you’re living in an older building that has smaller pipes installed, it can cause hot water restriction before it reaches the taps of your kitchen and bathrooms. The only way to fix this problem is by installing new ¾ inch water lines to your existing system. Also, another possible reason for low water pressure in the pipes can be magnesium and calcium formation in the pipes. The presence of calcium and magnesium in the pipes can lower their diameter, restricting hot water travel to your bathroom and kitchen.
