Question 3

In a hydronic heating system, what is the primary function of a circulating pump?

Accepted Answer

To continuously circulate heated water throughout the system

Answer

To directly heat the water using a heating element

Answer

To control the flow rate of water within the system

Question 4

What is the recommended practice for designing a hydronic heating system for a large building, ensuring efficient and comfortable heating?

Accepted Answer

Divide the building into multiple zones, each with its own thermostat for individual temperature control

Answer

Use a manual radiator control system, requiring manual adjustments

Answer

Employ a single zone with a centrally located thermostat for the entire building

Answer

Install a radiant floor heating system, distributing heat evenly

Question 5

What is the main purpose of a heat exchanger in a hydronic heating system?

Accepted Answer

To transfer heat from the heated water to the air in the building

Answer

To control the flow rate of water within the system

Answer

To prevent corrosion in the system's pipes and components

Answer

To circulate heated water throughout the system

Question 6

When selecting the diameter of pipes for a hydronic system, which factor plays a crucial role?

Accepted Answer

The desired water flow rate to ensure adequate heating

Answer

The thickness of insulation used on the pipes

Answer

The material used to construct the pipes

Answer

The total length of pipes used in the system

Question 7

What is the main function of an expansion tank in a hydronic heating system?

Accepted Answer

To accommodate changes in water volume caused by temperature fluctuations

Answer

To store hot water for later use in the system

Answer

To prevent pipes from freezing during cold weather

Question 8

What is the recommended practice for designing a hydronic heating system for a cold climate, preventing freezing issues?

Accepted Answer

Use a closed-loop system with antifreeze added to the water

Answer

Install a radiant floor heating system, providing even heat distribution

Answer

Use an open-loop system without antifreeze, relying on heat alone

Question 9

What is the main advantage of using a variable-speed circulating pump in a hydronic heating system?
