A system-level view of heat loss, emitters, hot water, controls, space, noise and electricity.
Practical Points
- 1.
Obtain a room-by-room heat-loss design and check emitter output at proposed flow temperatures.
- 2.
Plan cylinder space, external-unit location, condensate, electrical capacity and controls.
- 3.
Confirm installer competence, commissioning information and maintenance arrangements.
Considerations & Trade-offs
The system may need larger emitters, plant space or electrical upgrades.
Noise, controls, tariffs and occupant habits affect operation and cost.
Concept Scenarios
CONCEPT CASE STUDY — NOT A D-CORE PROJECT
Passive retrofit concept
A staged retrofit thought experiment starting with diagnosis and envelope continuity, then ventilation and heating decisions.
Options Included:
- Survey and repair first
- Airtightness and ventilation package
- Fabric works sequenced with heat-pump readiness
