As a consumer, one of the first things we want to know when purchasing an appliance is how long it would be able to last us. In this article, we will be taking a deeper dive into how long a tankless water heater should last you and what you can do to extend its lifespan.
A tankless water heater – also known as an instant water heater, is a common household appliance in most Malaysian homes. It heats up water on-demand, providing users with a never-ending supply of hot water at their desired temperature.
The honest answer is that, like with all appliances, it depends. However, with that being said, you can still expect most tankless water heaters to serve you for approximately 15 to 20 years. For the purpose of comparison, the lifespan of traditional storage water heaters is typically around 10 years.
This estimate is based on the industry average, the presence of certain features and a normal pattern of usage. When we understand the factors that affect the lifespan of the water heater units better, we would be better equipped with valuable knowledge that would help us select a tankless water heater that has a longer estimated lifespan. Additionally, with the points mentioned below, we would also be able to perform certain simple but effective tips to extend the water heating unit’s overall lifespan.
There are 2 key factors behind the tankless water heaters’ longer operational lifetime compared to traditional storage water heaters:
Storage water heaters function by storing a large amount of water in its tank and will operate to keep that water constantly heated 24/7. As you can imagine, this greatly increases the amount of wear and tear on the appliance as it needs to go through continuous heating cycles to ensure that the water in its tank stays at the desired temperature set. On the other hand, tankless water heaters only run whenever we switch it on to take a shower. Thus, overall running usage is much lower than that of a traditional storage water heater.
Storage water heaters and their tanks are exposed to water 24/7. In an area with hard water – where there is high mineral content – the hard water can cause build-up and result in corrosion of water pipes and home appliances. Since storage water heaters are constantly exposed to water, it may be more prone to corrosion, especially if it is in constant contact with “hard water”. Most of the common issues we typically associate with water heaters such as water discolouration, sediment in the water and leaking ceilings, in fact, stem from corroded or rusted storage tanks. However, since tankless water heaters do not require a tank to operate, this minimizes the risk of corrosion and all its related issues.
It can be tempting to skimp on installation costs and proceed with a DIY project, however, it is important to note that having a proper installation is a major determinant of the lifespan of a water heater. Improper installation can result in leaks and water pressure issues within just a few years. Having a water heating appliance improperly installed will not only create a hassle to repair it and result in unnecessary costs incurred but will also knock years off the expected lifespan of the water heating unit. Ensure that your investment lasts by having your water heater installed by a professional.
There are no two ways about it: preventative maintenance is always cheaper than repairs. While the tankless water heater is an extremely low-maintenance household appliance, it is still a device with various moving parts and electrical components. Additionally, it is also an appliance that is used regularly and maybe even multiple times daily. Thus, for optimal performance, it would be highly recommended to schedule professional maintenance, servicing and inspections for your water heater. Maintenance is needed because, over time, mineral deposits will build up within the heating chamber of your tankless water heater. You could also consider installing a water filter to minimise deposit build-up. With regular maintenance, you can address and find any issues with the water heater early and prevent it from snowballing.
Not all tankless water heaters are created equal. An established, trustworthy and reputable manufacturer is far more likely to produce more reliable, durable and high-quality water heaters that can withstand the test of time.
