PLANNING / SELECTION / HANDOVER
Before choosing the equipment
Ask how the selected combination performs when several zones need heating at once. Discuss minimum output, small-room needs and the consequences of placing all zones on shared equipment.
What belongs in the quote
Request the exact combination schedule and routing plan. Clarify condensate service access and how a fault or service shutdown could affect the connected rooms.
Think about the surrounding system
Ask for the proposed equipment combination, its capacity at your design outdoor temperature and a written backup-heat strategy. Compare electrical work, distribution changes, condensate handling and controls alongside the outdoor unit. A brand name alone does not describe the complete system.
Three questions for your contractor
- How was each indoor unit selected?
- What happens during simultaneous demand?
- How will shared-system downtime be managed?
Prepare a useful first conversation
Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.
This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
