Tankless Water Heating System Problems:
Tankless water heating systems (also recognized as on-demand water heating units) are more competent than standard heating units that continually utilize energy for keeping a big tank of water hot. Instead, they rapidly heat the water as required when you switch on the hot tap. However, upgrading to a tankless water heating device is much like replacing your old vehicle. New models are likely more power-efficient and have lots of new whistles and bells, but both new vehicles and new tankless water heating devices also utilize advanced sensors and other electronics.
It denotes they’ve more audible and visible signs of potential issues. However, they might also be more difficult to fix and troubleshoot than simpler, older water heating devices. A best -quality Tankless Water Heating unit ought to last twenty years, but it has to be well maintained. Corrosion, hard water (directing to mineral build-up), improper installation and excessive demand can all reason issues with your Tankless Water Heating Systems. We have discussed a few Tankless Water Problems down here.
Problem#1: Mineral Buildup
Whether you make use of a tankless or a traditional water heating unit, you have to keep your eye out for the mineral buildup inside the water heating device. The hard water is with great mineral content and the harder the water, the more the chance for harming mineral buildup. Magnesium and Calcium are the two minerals that most frequently reason scaly increase, and it can damage the function of the water heating unit if you do not address is. For avoiding this, flush the water heating device every six months. You can also make use of the water softener for slowing this buildup.
The tankless water heating devices are less subject to this problem than the tank-type ones. However, if it does happen, it can direct to serious issues. Condensation might drip onto on your gas burner and reason corrosion that obstructs your gas supply. Though unlikely, even a little restriction can reason the sensitive computer in your tankless water heating unit to shut down your system. A poorly fitted heat exchanger can also be damaged by this. If fitted correctly, it ought to not be a problem for the lifespan of your heater. However, in the unlikely case of a corroded heat exchanger, substitution can be extremely expensive.
Problem#3: Ignition Failure
There’re numerous causes the water heating device can fail to ignite. Frequently, this problem is reasoned by your gas supply, so check to make certain the propane tank is full before you carry out anything else. If the water valves or gas valve aren’t completely opened, it can also cause your ignition to fail. Check and open water and gas valves completely. If such steps don’t fix the ignition issue, then either the ignition pack has failed, or there is a bigger issue. You ought to call technical support for assisting you in troubleshooting the problem and order replacement components if essential.
Problem#4: A Cold Water Blast
Only because tankless water heating units provide a limitless supply of hot water does not denote they produce immediate hot water. The hot water still needs to travel through pipes between the tankless water heating device and your fixture. If the Navien water heating device is on one side of your home, and the shower is on some other, it might take some moments for clearing out your cooled water that sat in your pipes between.
Remember that if the family is moving through your shower routine, the hot water can stay close to your shower, with the cold water settling in between. If you jump straight in, that second cold water blast after some moments is not a sign of something wrong. It is only the system playing catch-up.
Problem#5: System Overload
Riding on the capacity of your tankless water heating device, too many concurrent hot water applications (like several showers running) can really overload the water heating system. The water heating device might struggle to provide hot water required or shut down altogether if it turns overloaded. If it occurs, you ought to decrease the hot water demand by limiting the concurrent applications, and you might desire to contemplate resetting the device.
However, if the tankless water heating system often becomes overloaded, you ought to contemplate either upgrading to the tankless water heating system with the better capacity or appending a second device. Although a 2nd device may seem like a large investment, it can really save you cash in the long run since you will utilize less water while waiting for the hot water to come and less gas for heating your water.
Problem#6: Combustion Shutdown
The Tankless water Heating Devices also have to be vented cautiously for avoiding other computer-generated failures. The heating units have extremely hot exhaust which must escape efficiently and quickly. If venting is restricted, the system might shut down your heating unit. Venting tubes that are convoluted or very long typically reason this kind of issue.
Problem#7: The Exhaust Or Air Supply Is Blocked
For most Tankless Water heating units, the display with show an error code for telling you that the exhaust or air supply is blocked. It denotes the water heating device is having problems with either the venting or combustion air. First, check all the venting pipes for making sure they’re connected correctly and free from stab holes. Refer to the device manual for making certain the clearance needs are being met, as fitting the water heating device too close to the other things can block the air supply and generate a fire hazard. Rodents, birds nest, and wasps nest can also block the venting, so be certain to carefully check all the vents that are lead or located outside the house.
Problem#8: Flame Failure
It is one of the Tankless Water Problems that is generally reasoned by either an electrical problem or the gas pressure issue. Just like the ignition failure, you ought to first exclude simple reasons like an unpaid gas bill or a low propane tank. Other possible reasons for this problem comprise a gas line that is very small, combustion problems, regulator failure, venting, and more. Call the technical support for assistance with the troubleshooting the problem further.
