What is a benefit of using a tankless water heater compared to a traditional boiler?

Using a tankless water heater instead of a traditional boiler provides the distinct benefit of eliminating the need for a storage tank. This design allows water to be heated on demand, meaning that it does not require a large reservoir to store hot water, which can occupy considerable space. As a direct consequence, tankless water heaters are more compact, making them an ideal choice in smaller homes or apartments where space is at a premium.

Additionally, the on-demand functionality allows for continuous hot water supply, as the system heats water as it flows through the unit. This contrasts with traditional boilers, which need time to refill and reheat a tank of water, potentially leading to shortages during peak usage times. Consequently, tankless systems can be more efficient and can provide substantial long-term savings on energy costs since they only operate when hot water is needed, minimizing wasted energy from keeping a tank of water heated at all times.
