Which system is used to supply hot water to fixtures in a home?

The hot water distribution system is specifically designed to deliver hot water from a water heater to various fixtures throughout a home, such as sinks, showers, and appliances. This system ensures that users have immediate access to hot water when needed, which is essential for comfort and functionality in residential plumbing.

The hot water distribution system typically includes insulated pipes that minimize heat loss, valves to control flow, and connections to each fixture that requires hot water. It operates in conjunction with the water heater, which heats the water to the desired temperature before distributing it through the system.

In contrast, the cold water distribution system is responsible for bringing cold water to fixtures, while a boiler system primarily serves the heating of water for hydronic heating applications, not directly for fixture supply. The ventilation system is unrelated to water supply, as it is involved in providing fresh air and regulating indoor air quality.
