Radiant heating manifold maintenance checklists

Radiant heating manifold maintenance checklists for the quarterly and annual rounds: 2 free lists, 10 items and 14 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

Radiant heating manifold quarterly maintenance checklistquarterly
Every quarter through the heating season, walked with the boiler and pumps. A manifold in a closet gets ignored until a floor runs cold. Run by: The hydronic or maintenance tech on the quarterly mechanical round.
Radiant heating manifold annual maintenance checklistannual
Once a year ahead of the heating season, paired with the boiler service so the whole loop is down at once. Run by: The hydronic service lead on the annual heating service before the season.

What most often fails on a radiant heating manifold

  • One loop reads dead flow on the meter because it airlocked and the vent was never opened.
  • System pressure has crept down below the fill setting and nobody topped it up.
  • A thermal actuator failed closed or lost its wire, so the zone it serves never gets heat.
  • Loops rebalanced by the flow meters without purging first, so an airlocked loop reads fine cold and starves once running.
  • Fill and system water never checked for treatment, and sludge quietly fouls the flow meters and actuator seats.

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.

Common questions

Which radiant heating manifold maintenance rounds do these checklists cover?
Radiant heating manifold quarterly maintenance checklist (quarterly): Every quarter through the heating season, walked with the boiler and pumps. A manifold in a closet gets ignored until a floor runs cold. Radiant heating manifold annual maintenance checklist (annual): Once a year ahead of the heating season, paired with the boiler service so the whole loop is down at once.
Who runs the radiant heating manifold maintenance round?
The hydronic or maintenance tech on the quarterly mechanical round. The hydronic service lead on the annual heating service before the season.

Which standards is radiant heating manifold 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 (10 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.
