TWO PIPE SYSTEM

FIRST POINT'S MISSION
At First Point Mechanical, we are committed to be well known in our industry for our high quality customer service, integrity and honesty.

WHAT IS A TWO PIPE SYSTEM and HOW IS ONE PROPERLY MAINTAINED?

Knowing what a two pipe system is and how to properly maintain it is critical as we transition from the heating season to the cooling season.  At First Point Mechanical, we have a great deal of first hand experience working with buildings that have two pipe systems.


Two pipe systems are systems that share the same piping, but can only supply heating or cooling at one time.  A two pipe system contains supply and return piping throughout the building and utilizes a series of valves that allows for only heating or only cooling water to be supplied, depending on the season.

These types of systems require planned shut downs and switch overs, usually around May 1-15 and again around September 1-15.

At the time these switch overs are performed, it may be necessary to drain the glycol from the heating systems and store for the cooling season.  The same may be true during the fall switch over.

During this time, it is also recommended to perform cooling operations start up on chillers as well as pumps serving these systems.

LOYOLA ACADEMY
Wilmette, IL

PROJECT DESCRIPTION
Reduce energy costs, enhance comfort controls and reduce equipment footprint

THE CHALLENGE
With only two existing thermostats for over 14 classrooms and offices, Loyola Academy was looking for a better way to control the temperature in each classroom and office.  Being located in the basement, the new system also had to be able to dehumidify to maximize its' occupants comfort. 

THE SOLUTION
With limited space above the ceilings, Loyola Academy and First Point's engineers worked together to find a system that would meet both the space limitations and provide additional comfort controls to the teaching staff. 

THE RESULT
First Point Mechanical designed and installed the Mitsubishi VRF system that provides each classroom and office simultaneous heating and cooling .  This project turned two thermostats into 14 individual controlled zones!  This project also freed up mechanical room space and allowed the building to utilize this additional space for storage and classroom use.
