A tankless water heater can last a lifetime with proper care. But as with any other mechanical system, it will eventually need repair or replacement.
Water temperature fluctuations are a common problem with tankless systems that costs $50 to $500 to repair. The cause can be something as simple as a fuse or as complicated as a burst pipe. Contact Tankless Water Heater Repair Denver for professional help.
If your water heater has a frozen pipe, it can be an expensive and inconvenient problem to resolve. But knowing what to look for can help you spot the issue early and take preventative measures to avoid future freezing.
Frozen pipes occur when the temperature outside dips below freezing for an extended period of time. They are most likely to freeze in unheated spaces such as an attic, crawl space, or basement. But they can also occur in other areas of your home such as behind exterior walls or under sinks. Frozen pipes are dangerous because they can burst, releasing water and possibly damaging the surrounding structure of your home.
When water freezes, it expands, putting pressure on the pipes and creating cracks as it does so. These leaks can then lead to more serious problems such as mold, flooding, and structural damage. If you have any of these issues, it’s important to call a plumber as soon as possible to thaw your pipes.
One of the first signs that you have a frozen pipe is turning on your faucet and finding only a trickle coming out. This may be caused by a blockage, or it could indicate that ice has already formed in the pipe. If you notice these symptoms, shut off your water supply and contact a plumber as soon as possible.
Another way to detect a frozen pipe is by noticing a damp or wet area around the affected section of your home. This may be due to a broken pipe or an underground leak.
To thaw the frozen pipes, start by turning off the water and power to the affected area. You can also use a heat source such as a hair dryer or heat gun to melt the ice. It is crucial to never directly contact the heat source with the pipe; excess or uneven heating can cause it to rupture. If you don’t have a hairdryer or heat gun, towels can be used to create an indirect heat source. Make sure to keep children and pets away from these sources of heat.
Rust
If you notice rust in your hot water, the corroded area can be repaired by mixing body filler with hardener and applying it to the rusted areas. When the body filler is fully dry, it should be sanded down to remove high spots and rough surfaces before painting. A new coat of paint should also be applied to the affected areas to protect them from further damage.
If your tankless water heater is not producing hot water, it could be due to a tripped breaker box or closed water supply valve. It could also be caused by a defective burner assembly, which is responsible for heating your water. A skilled plumber will be able to determine whether you have a problem with your water supply or your heater and make the appropriate repairs.
Another issue that may require repair or replacement is a faulty gas supply line. If the leaking or damaged pipe is not repaired, your gas supply could be interrupted. The cost to fix a gas flex line or replace it entirely can range from $200 to $500 depending on the location, material, and size of the pipe.
A loud rumbling noise from your water heater is a sign of excessive sediment buildup or a mechanical failure within the system. The noises can include banging, popping, crackling, hissing, or booming sounds. If left unchecked, the problem can get worse and lead to a complete shutdown of the unit.

Loud Rumbling Noises
Tankless water heaters are great for their endless supply of hot water and energy efficiency, but they can still experience problems just like any other appliance. If you’re noticing loud rumbling noises coming from your unit, there may be an issue with the gas line, a heating element, or loose piping. The good news is that these issues are usually repairable, so you don’t have to get a new water heater right away.
A lot of time, these rumbling sounds are caused by air buildup in your pipes. Vents that are supposed to let air out of your heating system get blocked, and this creates pockets of air throughout the entire piping system. When a gush of water hits these areas, it causes the air to hit against the bottom of the pipe like a hammer and make those rumbling noises you hear.
If you’re noticing this issue, shut off the water supply to your home by turning off your water heater’s gas valve or tripping its breaker. Then, remove the access panel or cover on your tankless water heater to gain access to its gas and electrical components. Your technician will disconnect the gas line and turn off the power by shutting off the breaker or turning the switch. They’ll then take your old unit apart and install the new one. They’ll replace all the internal parts, make sure it’s leveled and anchored correctly, clean out your thermal expansion tank, check gas sediment traps, check for proper venting, and ensure the correct size of your gas line and flex hose is used.
Leaking is another common problem with tankless water heaters, but it’s also one of the easiest to fix. The leaks are often caused by worn-out seals or gaskets, and they can also be caused by excess pressure within the system. A tankless water heater replacement technician will test the unit’s temperature settings and the incoming gas pressure to determine what’s causing it to leak.
Typically, a pilot light repair on a tankless water heater costs between $75 and $150. The pilot light is a small flame that lights the water heater’s burner to heat it, and it can become damaged or clogged by debris or scale. A technician can clean the pilot light and relight it if necessary.
Ignition Failure
Whether your tankless water heater is gas or electrical, it relies on a series of complex processes to ignite and heat the water. If your system is experiencing ignition failure, there may be a number of issues ranging from a simple lack of fuel to more serious problems with the igniter or flame sensor. Regardless of the cause, professional diagnostics are essential for determining the best course of action.
An electrical problem with a tankless unit may be caused by a wire short or a power outage. If you’re dealing with a gas model, an issue with the ignition may stem from a problem with the valve, or could be caused by a blockage in the venting system (usually due to nesting animals or debris). In either case, professional inspection is required to determine the exact cause and make the necessary repairs.
If your unit is emitting a rotten egg smell, it may indicate that the water has become contaminated with hydrogen sulfide, a dangerous chemical. The odor can also be caused by excessive sediment buildup, which requires professional draining and flushing to address.
A recurring inconsistency in water temperature may be the result of mineral buildup. Regular decalcing and maintenance will help keep the temperature stable, and will ensure that your water heater is operating at peak efficiency.
The cost of fixing a noisy tankless water heater will vary depending on the problem, with one of the most common being a dud heat exchanger. A replacement will require dismantling the unit, taking out all the parts that have corroded or failed and rebuilding them with new ones. A full heat exchanger repair is typically a costly job.
It’s important to note that most of these issues are preventable by performing routine maintenance with a qualified tankless water heater repair company. A yearly checkup can catch many potential problems before they can develop, saving you money and inconvenience in the long run. If you’re considering upgrading to a new tankless water heater, contact a professional to weigh the pros and cons of repair versus replacement.
