What Does the Anode Rod in My Water Heater Do?

Water heaters are essential to modern life. However, most of us have very little idea of how they work, beyond the basics. We know that water flows into the cylinder from the mains, that it is heated, and that the temperature is maintained by good insulation around the cylinder, but that’s about it. Most of the other components are mysteries to us. For instance, what’s an anode rod and what does it do?   What Is an Anode Rod? You may hear it called an anode rod, or a sacrificial anode rod, but they are both the same thing. It’s a metal rod that’s extended into the cylinder of the water heater. It serves just one purpose – to attract corrosive elements and prevent them from causing damage to the cylinder walls. An electric current flows through the rod, charging it, and attracting particles with the opposite charge. As the particles collect, the rode corrodes, eventually succumbing to the damage and needing to be replaced.   What Is an Anode Rod Made From? Anode rods are made from metal, but different metals can be used. You will find they’re made of either magnesium, aluminium, or zinc. Each metal offers something a little bit different. Magnesium – Magnesium is the best-performing metal for anode rod construction, but it’s the least durable. It generates around 1.6 volts in the cylinder but may need to be replaced every year if your water is particularly hard or soft. Aluminium – Aluminium generates 1.1 volts and is the middle ground when it comes to anode construction. You’ll need to inspect it annually, but usually, they will only need to be replaced every five years or so. Zinc – This is the lowest performance material, generating just 1.05 volts. It has a lifespan pretty comparable with aluminium.   What Happens When an Anode Rod Fails? So, what happens when you anode rod eventually reaches the end of its lifespan? Does your water heater stop working? No, but the process of failure is accelerated. The anode rod prevents corrosive agents from attacking the walls of the cylinder. Without it, those corrosive elements go to work eating away at the inside of your cylinder, eventually causing serious problems, and, ultimately, failure.   Signs of Anode Rod Failure How do you know when your anode rod has failed? Ideally, you’ll have a water heater maintenance service inspect everything once per year. This is the only way to guarantee that you are able to replace the rod before it fails completely and extend the lifespan of your water heater. However, there are signs you can look for that may indicate your rod has already failed. It may or may not be too late to save the cylinder. Some of these signs include: Popping sounds during water heater operation Clogging faucet aerators Slimy gel on faucet aerators Water is warm but not as hot as it used to be Concerned that your anode rod might be about to fail, or have already failed?

Water Heater Troubleshooting: Understanding Common Problems with Unvented Cylinders

Today, unvented cylinders are the most frequently recommended option for residential hot water needs. They offer superior pressure in the shower and at the taps compared to vented cylinders. They do not take up as much room as vented cylinders, and they can be installed just about anywhere that there’s access to the mains, as well. However, they can suffer from a few common issues. For homeowners, it’s important to understand the most common problems you might face with an unvented cylinder.   No Hot Water   Perhaps the single most common problem you might experience with an unvented cylinder is no hot water. This can present as cold water when you open the hot tap, or no water flow at all from the hot tap. A couple of different issues can cause this problem, including no power to the water heater due to a tripped circuit breaker, or a problem with the residual current device installed on the unit. Regular maintenance will ensure that there are no reasons for your water heater to trip the breaker and that the RCD is in good working condition, as well.   Thermostat Issues   Your unvented cylinder will be equipped with a thermostat. This allows you to set the temperature on the water heater to your preferences (and to ensure safety for members of your household). It is also an important tool for helping to prevent overheating and overpressure situations. It is possible for the thermostat to malfunction in a number of ways, all of which can be prevented through annual inspections and regular maintenance by a G3-certified plumber.   Expansion Vessel or Air Bubble Problems   Unvented cylinders have either an expansion tank or an air bubble system. This allows the unit to accommodate the increased volume of heated water without any danger. However, both expansion tanks and air bubble systems can become depleted over time. This mean there is less expansion room for heated water and increased risk for your home. Annual maintenance is the best way to avoid this problem.   Pressure Relief Valve   Hot water creates a great deal of pressure within an unvented cylinder. If this builds up to dangerous levels, the tank could split. A pressure relief valve helps prevent this from happening by allowing excess pressure to be vented. If the valve fails, this cannot happen, though. Again, annual maintenance ensures that this valve is in working order.   Pressure Reducing Valve Failure   Because an unvented cylinder is connected directly to the mains, a pressure reducing valve is needed to ensure that incoming water pressure remains at a safe level. If the valve were to fail, the cylinder could become over pressured. Annual service ensures that your valve remains in good working condition.   As you can see, the single most important thing to do to prevent these common problems with unvented cylinders is to ensure that your water heater is properly serviced and maintained.
