Summary
As the days grow shorter and temperatures drop, heating systems are finally turned on after a long period of disuse. This time of year signals the important task of evaluating a building’s energy system to ensure it is equipped to deliver heat efficiently and safely.
Building owners must establish a preventive maintenance program with their energy provider to maintain efficient energy delivery, avoid equipment failures, reduce energy costs, and ensure the long-term sustainability of a commercial property.
A heat exchanger is a system that transfers heat between a source and a working fluid. District energy systems transfer heat from the hot water in the district heating system to the cold water in an individual building’s heating system.
To ensure that heat exchangers function properly, Vicinity’s team takes water samples from the heat exchanger and tests the water for conductivity. This test helps ensure that tube bundles are not leaking and that city water is not entering the system through such leaks.
Vicinity’s team also drains cooling tower heaters during cold weather. When temperatures are expected to be below 20 degrees F for an extended period, the cooling tower basin heaters are drained below the building roof level, the basin heater is turned off, and space heaters are turned on as applicable. Our team also works to adjust glycol or other antifreeze concentrations throughout the cooling system, as required.
