Costs of Tankless Water Heater Repair

If you are considering purchasing a tankless water heater, understanding what repairs can cost can help you compare costs. Here are some of the most common Tankless Water Heater Repair Denver costs.

Tankless Water Heater

Leaks in tankless water heaters typically require professional attention. Depending on the severity, these could be costly repairs or replacements.

While tankless water heaters are more energy efficient than traditional systems, they can still experience problems with their components. Some issues are relatively simple and inexpensive to repair, but others require more involved repairs or replacement parts. A broken heating element is one of the most common issues that homeowners encounter with their tankless water heaters. This part is responsible for heating the water directly, so it is important that it is working properly.

If you notice that your water is discolored or has a bad smell, this may be a sign that the heating element is broken. Alternatively, it could be caused by a problem with the system’s thermostat or by sediment buildup. The best way to resolve these issues is to call a professional for a complete flushing of the system.

The average cost to repair a broken heating element in a tankless water heater is $200. Before starting the repair, make sure that the unit is completely cool. You will need to shut off the power and water supply before you begin. After that, remove the access panel and insulation covering the heating element terminal block. Once you have removed this, expose the screw terminals where the circuit wires are connected to the heating element. Next, remove the old element by twisting it counterclockwise with a socket wrench.

When you install the new element, make sure that it matches your system’s voltage and wattage. This information can be found on the manufacturer’s data plate or on the element itself. You should also make sure that the new element has a gasket and is the right size for your system’s tank.

If you’re unsure that your tankless water heater is operating correctly, you can test it with a multimeter. It is important to note that you should not attempt to repair your own water heater if you don’t have the proper tools and knowledge. This can result in electrical hazards and additional damage to your water heater. It’s also a good idea to have a professional inspect your tankless water heater on a regular basis, so that it can be maintained and repaired properly.

Frozen Pipes

If you turn on your hot water faucet in a freezing winter month and only a dribble of water flows out, it may be caused by frozen pipes. Frozen pipes are a serious problem, as the ice inside them puts a lot of pressure on the pipe walls. A frozen pipe can burst, which can lead to massive water damage and flooding in your home. If you suspect a frozen pipe, try turning on your other faucets to relieve the pressure and give the affected pipe time to thaw.

If the problem persists, you should contact a professional to resolve it. You can prevent your tankless water heater from freezing by implementing proper insulation on the unit and its associated water supply lines. A professional can also help you identify and resolve other problems that could cause your tankless water heater to freeze, such as blown fuses or tripped circuit breakers.

There are several ways to unfreeze a tankless water heater, but you should always disconnect the power and water supply before attempting any method. You can use a heat lamp or an incandescent light bulb to provide localized heat to the frozen area and speed up the process. You can also wrap the affected pipe in a heated towel to thaw it. If you do this, it’s essential to replace the towel every 10 minutes so that the pipe doesn’t overheat.

Other signs that your tankless water heater is frozen include a lack of hot water, fluctuating water temperatures and strange noises coming from the unit. Frozen water heaters can also create water leaks, which can lead to major water damage in your home.

When choosing a technician to perform a tankless water heater repair, you should look for a professional with extensive experience working with this type of equipment. A professional should also have a valid license, certification and good reviews from previous clients. A professional will be able to identify and fix the most complex problems, and they’ll know how to handle them safely. Additionally, a qualified technician will be able to recommend preventive maintenance tasks that you can do to extend the life of your unit.


If you notice rust-colored water coming out of your hot water taps, it may not necessarily mean that your heater is about to die. Instead, it could be a sign that it’s time to replace the sacrificial anode rod in your water heater, which can often be done during the same service appointment. The anode rod is designed to rust before the metal tank lining, protecting the tank from corrosion and preserving the life of the device.

Another cause of rusty water can be sediment buildup in the tank itself or in the supply lines. If this is the case, a professional can often perform a quick and easy tank flush to remove any excess sediment and restore the quality of your water.

Corrosion can also be caused by the presence of bacterial growth in your home’s water, which can lead to discoloration. In this case, sanitizing the entire water system with a chlorine treatment and flushing the pipes should resolve the issue.

Visible rust spots on the tank itself are also a warning signal, indicating that it is nearing the end of its expected lifespan and that you should consider replacing it. Seeing these signs should prompt you to call for a service appointment as soon as possible, so that we can determine the best solution for your needs.

The dreaded cold water sandwich is sometimes caused by the fact that someone else in your home showered right before you did, leaving you with their leftover warm shower water. The best way to avoid this is to install a timer on your bathroom water fixture so that you are only getting your own clean, hot water when it’s necessary.

The dreaded smelly, metallic taste of your hot water is a sign that the mineral and iron levels in your home’s water are too high. This problem can usually be resolved by a professional who can help you with a whole-house water filtering system. If the issue is severe, however, you may need to have your water heater replaced altogether.

Rotten Egg Smell

If you notice a rotten egg smell, the first thing you should do is call your local plumber. They will be able to help you find the source of the smell and repair it. If the problem is with your drain pipes, for example, they can clean them and remove any clogs. Another possibility is that there’s a gas leak somewhere in your house. This is something that should always be checked by a professional as it can be dangerous. They will be able to test your gas lines for leaks with special equipment. They will also be able to inspect your water heater for any problems.

The odor of rotten eggs is often caused by hydrogen sulfide from your tankless water heater. Most electric water heaters have magnesium anode rods that are made of magnesium sulfate to prevent corrosion of the tank. When these rods corrode, they produce hydrogen sulfide which causes the rotten egg smell. A plumber can replace the rod and install an aluminum one to avoid this issue in the future.

There are also some cases where the rotten egg smell comes from a sewer gas problem. This can happen when the p-trap in a sink or tub hasn’t been used in awhile. When this happens, the trap dries up and lets sewer gas into your home. This is especially a concern if the toilet has been left open or if food has been thrown in the garbage disposal.

Another possible cause is a clogged sewage pipe that connects to your water heater. This is a serious problem that should be dealt with immediately. It is important to have your water heater checked regularly by a plumber to ensure that everything is working properly.

A faulty thermocouple can also make your water heater emit a rotten egg smell. The thermocouple is a sensor that measures temperature and sends this information to the control unit. If the thermocouple is faulty, it will not signal the water heater to turn on when needed and you may experience no hot water or low water pressure.
