The design of a tankless water heater is completely different from that of a tank heater, which means the upkeep is also unique. There is no actual combustion needed to heat the water and while problems are less frequent in tankless water heaters, an annual service check is strongly recommended.
Once a year, a tankless heater should be flushed out. The purpose of this is to remove the accumulation of limescale and minerals. It will also allow the tankless heater to operate with a higher level of efficiency. Flushing an electric heater is one of the most highly recommended forms of preventative maintenance.
Another that should be addressed is the air filter. There are certain manufacturers that recommend routine cleaning. Many homeowners get caught up in the busyness of their daily lives and the end result is a dirty air filter. However, annual service can remediate such problems.
It is important to note that warranties on tankless water heaters are not guarantees that the unit will be immune to breakdowns. Warranties are there for protection in case something goes wrong, but that does not negate the need for preventative maintenance.
There are several forms of preventative maintenance which can help to extend the lifespan of a tankless water heater. The life expectancy is about 20 years, but that is made possible through upkeep and maintenance. There are many preventative maintenance tasks homeowners do not know how to do.
For example, the inlet water strainer should be kept clean and there is also a need to give the sediment trap a good cleaning. Preventative maintenance on an annual basis will also focus on inspections of the water or gas shut-off, as well as the condensate drain. If there is a problem with any of these components, even a minor one, it could result in more expensive repairs down the line.
The presence of hard water is also something that could accelerate problems with a tankless water heater. If you live in an area where hard water is prominent, then it’s a good idea to service your tankless heater once a year.
