Before ordering equipment, agree the design evidence and responsibilities. This installation checklist is for installers, project contractors and purchasing teams; it does not set one capacity, electrical supply or subsidy requirement for all European homes.
Hydraulic design checks
First, request room-by-room heat loss and the local winter design temperature. Include ventilation and planned renovation. Second, check radiator, floor or fan-coil output at the proposed flow temperature, with a hydraulic plan showing design flow and the unit’s minimum flow requirements. A buffer tank is a design choice, not an automatic requirement for every installation.
Site-specific assessment
Third, have an electrician check the supply, simultaneous loads, protective devices and the purpose of backup heat. Fourth, document the outdoor position, manufacturer safety clearances, service access, sound assessment and condensate route. Resolve responsibilities for frost protection and power interruptions.
Commissioning and handover
Fifth, set commissioning and acceptance criteria: hydraulic balance, control settings, heat and hot-water operation, alarms, user training and a record of baseline readings. Confirm any project-specific permissions and funding eligibility from the current official programme before relying on it in a quote.
Supplier evidence and responsibilities
A distributor should ask which tasks are included in equipment supply and which remain with the local contractor. A complete specification reduces surprise extras and provides a traceable handover. Floor area, energy certificate grade and headline COP are not substitutes for system design.

Before requesting a project quotation
| Check | Information to prepare |
|---|---|
| Project scope | State the country, project type, operating conditions and required delivery date. Identify which decisions still need an installer or designer. |
| Topic-specific evidence | a site survey, hydraulic schematic and commissioning scope |
| Responsibility and acceptance | Record who supplies, installs, commissions and services the equipment. Ask which documents and checks are included, and confirm exclusions in writing. |
This checklist helps define a request; it is not a model performance claim, installation design or promise of availability.
