Room-by-room heat loss, simplified method based on EN 12831
What the house needs at each outdoor temperature: heating below the average indoor temperature, cooling above it
| Room | Floor | Area | Target °C | Heat Loss (W) | Emitter Output | Balance | Status |
|---|
Verification of pipe sizing, friction pressure loss, circulator head, and actual delivered thermal output per emitter.
| Element / Emitter | Type | Target Output | Delivered Output | Capacity % | Design Flow (L/min) | Run / ΔP / Balancing | Hydraulic Status & Diagnosis |
|---|
Estimate heat loss from a gas or oil bill. No drawing needed.
