A central domestic hot water system typically does what?

A central domestic hot water system primarily heats water in an equipment room and then distributes it throughout the building to various fixtures, such as sinks and showers. This design allows for a consistent supply of hot water to multiple locations, enhancing efficiency and reducing the need for individual heating units at each faucet or fixture.

The benefit of this system is that it can maintain water at an appropriate temperature for use, while also minimizing energy waste. Centralized heating allows for better management of water temperature and quality, which is critical for preventing issues like Legionella growth.

This option stands in contrast to storing hot water in individual tanks, which may lead to inconsistencies in temperature and potential stagnation. Generating steam for heating purposes does not relate directly to providing hot water for domestic use, while supporting only one or two fixtures implies a limited and inefficient supply system not representative of a central domestic hot water system's capabilities.
