Tankless water heaters are some of the best innovations that you can ever invest in. The newer models keep getting more efficient each year. They are great when you want to save money and if you set them up in the right way, you could reap the benefits of having a tankless water heater for a long time.
As with all home appliances that are in constant use, even the best tankless water heaters will develop some problems that are fairly common in all of them. If you learn what these problems are, you will find it easier to deal with them than when you have no idea what is happening.
Here are 5 of the most common of them and what you can do about them.
- Buildup of Minerals
Water contains minerals that will form sediments inside the tanks. The harder the water you have, the faster and more the mineral buildup. Calcium and magnesium are the ones that usually form the buildup. The buildup is usually scaly and can be slowed down using water softeners. In order to make sure that this does not become a problem, flush the hot water at least once or twice every year. Some of the newer models have sensors that can tell you when this is getting bad so that you can stop it in time.
- Overloading the System
Excessive continuous use, even for the best tankless water heater, should be avoided. If you have a lot of people in the house or you are doing a lot of things that need you to use hot water, the system will be hard pressed to supply what you need and sometimes shut down. You will need to keep the demand reasonable and reset the unit you have. If this keeps happening a lot, you should get a bigger unit to take care of the demand that you may be facing or add another unit to the first one. It is cheaper in the long run.
- A Cold Water Burst (The Sandwich)
Let us say that someone just showered and then you step in. You feel the warm water and then suddenly, it gets very cold. Then, it goes back to hot again. So, here is what happened; when the first person turned it off, there was warm water left in the pipes. Behind that is the cold water. So, you get the warm water left, the cold water and then the one that gets warmed when you turned on the machine. It is all about the distance the water travels. This is not about the heater malfunctioning. Keep the heater distance short to avoid this.
- Air Supply or Exhaust Blockage Error
When you get this message, it means that the water heater is developing problems with the combustion air or venting. Check the vent pipes connections for holes or any leaks. Check to see if there are any blockages that could be caused by birds nesting, wasps or even rodents. If you do not see anything, have the fan motor or any other part you can’t reach checked. There is always something that you will miss when you do an initial check. It is recommended that you hire a professional to do it because some of the finer details are a bit complex for an amateur.
- The ‘No Ignition’ Message
This message lets you know that the water heater is trying to come on but something is preventing it from doing so. The problem is usually related to venting or the gas supply. To find the best tankless water heater, you need to look at tankless water heater reviews to get the best advice. Some of these errors are from heaters that are not that great in terms of quality. You should see if the gas bill is paid or fill the tank if you get this message. If the problem is deeper, get a professional to check it out for you.
