Thermal energy storage tank maintenance checklists

Thermal energy storage tank maintenance checklists for the quarterly and annual rounds: 2 free lists, 8 items and 12 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IMC (mechanical code); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule

Thermal energy storage tank quarterly maintenance checklistquarterly
Every quarter through the cooling season, walked with the chiller plant. A tank that stops shifting load quietly costs demand charges long before anyone notices. Run by: The HVAC or maintenance tech on the quarterly mechanical round.
Thermal energy storage tank annual maintenance checklistannual
Once a year during a plant shoulder period, when the tank can be taken through a full cycle without risking comfort. Run by: The HVAC service lead on the annual plant service.

What most often fails on a thermal energy storage tank

  • Sweating and dripping at the insulation and vapor seal, so the tank loses capacity and rots its own jacket and the floor under it.
  • Charge and discharge temperatures drift together, so the tank is cycling water without actually storing usable cooling.
  • Level reading stuck or off, so the plant controls charge and discharge on a level that is no longer real.
  • Vapor seal patched over a wet spot without finding where the moisture is getting in, so the insulation keeps sweating from the inside.
  • Storage water never checked for treatment, so scale and biological growth foul the tank and the heat-exchange surfaces.

Verified against

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.

Can I run these checklists in RTI?
Yes. Start a free RTI workspace and load any of the 2 lists (8 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
