Where should a compression tank be located for effective operation?

The correct response is that a compression tank should be located above the boiler to ensure effective operation. This positioning is essential because it allows for the proper flow of air to the compression tank, which is crucial for its function. When the tank is placed above the boiler, it utilizes gravity to help maintain the necessary pressure differential and ensures that any excess water can flow back into the system. This alignment helps in managing thermal expansion and provides adequate space for air separation, allowing the system to function more efficiently and effectively.

The other locations mentioned would not provide the same level of effectiveness. A tank located below the boiler might create issues with air pockets or insufficient water flow, while placing it on the side could lead to similar complications, as both positions would not facilitate the natural movement of air and water as efficiently as a position above the boiler. Meanwhile, positioning the tank in the basement could improve insulation, but it would not serve to enhance the operational dynamics necessary for effective function.
