Example setup
Example setup: changing the heating system
Question: under one weather and comfort basis, how do purchased fuel, heat-pump electricity and backup heat compare? This page defines an educational setup; it does not report a completed simulation.
Describe the baseline
- Existing fuel and boiler efficiency assumptions, with a dated fuel price.
- Building envelope and the heating setpoint schedule.
- Hot-water demand and any modeled distribution or storage assumptions.
Define the heat-pump alternative
- A supported heat-pump configuration and its performance data source.
- Emitter type and flow temperature, with backup-heater assumptions.
- The same weather, comfort and hot-water demand as the baseline.
Report separately
Show useful heat, purchased fuel, heat-pump electricity, backup-heater electricity and operating cost as separate quantities. Installation cost, maintenance and subsidies need their own sourced assumptions.
