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.

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which thermal energy storage tank maintenance rounds do these checklists cover?
- Thermal energy storage tank quarterly maintenance checklist (quarterly): 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. Thermal energy storage tank annual maintenance checklist (annual): Once a year during a plant shoulder period, when the tank can be taken through a full cycle without risking comfort.
- Who runs the thermal energy storage tank maintenance round?
- The HVAC or maintenance tech on the quarterly mechanical round. The HVAC service lead on the annual plant service.

- Which standards is thermal energy storage tank work verified against?
- IMC (mechanical code), published by the International Code Council. 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.
