Nine Signs You Need to Replace Your Hot Water System

Solar water heaters are an excellent investment. However, they are delicate and require proper maintenance. You should always do your research thoroughly, check the different models, and choose the right one for your house.

Here are some signs that your current water system needs maintenance or replacing.

1. The Hot Water System Is Old

The manufacturing date and your solar water heater model are important information you need to be mindful of. Age is a crucial factor for hot water systems, and if your heater is past its life expectancy, you need to replace it. Conduct a plumbing inspection to check if your hot water system needs replacing.

2. The Hot Water System Makes Weird Noises

A problem is present if you can hear banging, hissing, or knocking noises from your solar water heating system when you use it. It usually indicates your hot water system has loose or moving parts that need checking. This is a clear warning and an indication for using an emergency plumbing service.

3. The Hot Water System Releases Rusty Water

If your tap or your shower release water that contains rust, it is a sign for you to replace your current hot water system. This occurs when there is a leak, but it usually means your hot water system has reached the end of its life. You need to replace your hot water system immediately if this occurs.

4. The Hot Water System Smells

If your tap or shower releases water with discolouration and a foul smell, this means bacteria rust have invaded the tank of your hot water system. This is not a good sign, and you should call a plumber immediately to conduct an emergency plumbing service. Have them check your tank to see the corrosion and replace them immediately if necessary.

5. The Hot Water System Has Reduced Efficiency

The efficiency of your solar water heater is a crucial indicator of its usefulness. If you notice a sudden increase in your electricity bill, but you have not bought and used new applications, there is something wrong with your unit’s efficiency. Have a plumber check whether it needs a replacement or not.

6. The Hot Water System Releases Water at Varying Temperatures

If your solar water heater releases water at varying temperatures, between too hot and too cold, there is something wrong with your hot water system. It could mean that your hot water system is struggling to produce water. Have a plumber check it to see if it needs any fixing or a replacement.

7. The Hot Water System’s Drain Valve Is Not Working

As time passes, the bottom of your solar water heater tank will collect sediment. As it builds up, it might break down the interior of the tank. This leads to the clogging of the drain valve, which prevents the water from coming out. When this happens, you need to replace it right away.

8. The Hot Water System Leaks

Leaks are common in hot water tanks, especially when they are not properly used. If your tank is leaking, you need to have it checked and replaced. You may not notice leaks at first, but you need to check for leaks if you see a sudden increase in your bills and hot water supply.

9. The Hot Water System Is Obstructing Your Flow

The water flow determines the efficiency of your hot water system through it. If you notice that the water flow has slowed down, it is time to replace the system. This could also result from gunk and sediment clogging the solar water heater. Draining your solar water heater regularly will decrease this threat.
