Tankless vs Tank Water Heater: Which One Is Better? 

Water heaters come in two main versions: tank and tankless. Choosing one may be confusing, considering that both have their upsides and advantages. If you want to narrow down to one, you need to know which one wins between tankless water heaters vs tank heaters. Take a look at how they compare against each other.

Upfront Cost

A tankless water heater is a more advanced system that is complex to install. Therefore, you can expect that its initial price is generally higher than that of a tank water heater. Considering its working principle and how it needs special skills to install, it only makes sense that you will pay extra for it. Luckily, it is worth the investment, even when it can be twice the price of a tank heater.

Cost in the Long Run

With a tankless water heater, you will spend more on the initial and installation costs. However, they are more cost-effective in the long run. They are energy-efficient and consume less energy, which means you will spend less on utility bills. Tank water heaters are more expensive in the long run since they have higher operating costs.


Another victory for tankless heaters in the tankless vs tank water heater debate is how they have an impressive lifespan. Operating for up to 20 years makes them more economical down the line. In contrast, tank heaters may be cheaper to purchase but serve you for only 10 years, which is not as cost-effective in the long run.


Tank heaters store enough water as needed and provide a steady supply for the house. Tankless heaters operate differently, providing hot water only when needed, saving a lot of energy in the process. In comparison, they are more energy-efficient, which means lower energy bills.

Hot Water Needs

One setback with tank water heaters is that they store the hot water in advance, so you must size it according to your needs. The more people there are in the house and the higher the demand for hot water, the bigger the system to go for. A tankless heater, on the other hand, is more convenient because it heats the water when it runs, so you never worry about hot water running out.
