Hot Water Plumbing Basics

Hot water plumbing refers to the plumbing system that distributes hot water to various parts of a structure. It differs from cold-water plumbing because it requires heating water prior to it being distributed throughout the structure. The primary elements of a hot water plumbing system are the water heater, pipes, valves, and fixtures. Water heaters are the primary component of a hot-water plumbing system. It heats the water and keeps it in storage until it is needed. The pipes transport the boiling hot water out of the water heater to the fixtures including showers and faucets. Valves control the flow of hot water while fixtures are used to distribute hot water to different parts within the structure.

Types of Hot Water Heaters

Tankless water heaters are more efficient in energy use and have a longer lifespan however, they are more expensive.
