VERT / GREEN
Measure loads, water temperatures and existing emitters before choosing equipment.
Air-to-water heat pump and hydronic system
Verify whether radiators, radiant floors or fan coils can actually heat the home at heat-pump-efficient water temperatures.
JAUNE / YELLOW
A system designed for very hot water may lack capacity with a low-temperature heat pump.
ROUGE / RED
Do not size from nominal output alone: design load, water temperature, backup and controls must be checked together.
Project triage
What the professional checks
The HVAC/hydronic designer verifies room loads, performance curves, temperatures, flow, buffer volume, backup and controls.
