Question

Quizplus · Accepted Answer

All the options listed are essential practices when installing forced hot water heating systems. A) Ensuring the minimum operating pressure is high enough to maintain water at the highest terminals ensures that the system can effectively circulate hot water throughout the entire system, even to areas that are higher up. B) Installing air vents at each terminal and at system high points is crucial for removing any air that gets trapped in the system, which can cause blockages and reduce heating efficiency. C) A compression tank is necessary to absorb pressure fluctuations that occur as water heats up and expands, helping to maintain a consistent system pressure and prevent damage.
