Hydronic and radiant-floor heating

Understand heat source, zones, circulators, temperatures, glycol and floor finishes before a system or flooring renovation.

Checked: 2026-08-21

VERT / GREEN

Document zones, thermostats, heat source and existing finish.

JAUNE / YELLOW

New flooring, heat pump/boiler or cold zone requires checking temperatures and finish thermal resistance.

ROUGE / RED

Leak, pressure loss, relief device, overheating or boiler modification: qualified technician.

Pre-work triage

Useful tools and measurements

  • Indicative infrared thermometer
  • Loop/zone map
  • Circulator and heat-source manuals
  • Flooring technical data

Having a tool does not make regulated work DIY.

What the professional checks

  • Measure supply/return temperatures and flows
  • Balance zones and check circulators/valves
  • Check compatibility of heat source, floor and controls
