These are shown in the table below. The vertical axis is the heating technology. The horizontal access is the choice made in the calculator. The first letter refers to the 'home heating electrification choice', the second letter refers to the 'home heating that isn't electric choice'. The value in each cell is the fraction of the total heat supplied by that technology. |  Choice: | | AA | | DD | | DA | | BA | | DB | | BB | | DC | | CC | | CA | | CB | | CD | | AD | | AC | | AB | | BC | | Gas boiler (old) | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gas boiler (new) | | 0.9 | | | | 0.2 | | | | | | | | | | | | | | | | | | | | | | | | | | Resisitive heating | | 0.1 | | 0.1 | | | | 0.1 | | | | | | 0.07 | | | | | | | | | | | | | | | | | | Oil-fired boiler | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Solid-fuel boiler | | | | | | | | | | | | 0.1 | | | | | | | | | | 0.1 | | 0.1 | | 0.1 | | 0.05 | | 0.15 | | Stirling engine μCHP | | | | | | | | | | | | | | | | | | 0.1 | | | | | | 0.19 | | 0.19 | | 0.24 | | | | Fuel-cell μCHP | | | | | | | | 0.9 | | | | | | | | | | 0.2 | | | | | | | | | | | | | | Air-source heat pump | | | | 0.6 | | 0.6 | | | | 0.5 | | | | 0.6 | | 0.58 | | | | 0.18 | | 0.25 | | | | | | | | 0.14 | | Ground-source heat pump | | | | 0.3 | | 0.2 | | 0 | | 0.3 | | 0.2 | | 0.3 | | 0.3 | | 0.3 | | 0.3 | | 0.25 | | | | | | | | 0.2 | | Geothermal | | | | | | | | | | | | | | | | 0.01 | | | | | | | | 0.01 | | 0.01 | | 0.01 | | | | Community scale gas CHP | | | | | | | | | | | | | | | | | | 0.33 | | | | 0.13 | | 0.3 | | 0.24 | | | | 0.15 | | Community scale solid-fuel CHP | | | | | | | | | | 0.2 | | 0.7 | | | | | | | | 0.45 | | 0.2 | | 0.33 | | 0.35 | | 0.63 | | 0.25 | | District heating from power stations | | | | | | | | | | | | | | 0.03 | | 0.11 | | 0.07 | | 0.07 | | 0.07 | | 0.07 | | 0.11 | | 0.07 | | 0.11 | To help users understand the different technology mixes, we have generated some 'tenary diagrams': # The first showing the trade-off between electric, individual & communal heating: Ternary diagram: electric, individual, communal # The second showing the trade-off between electric, solid & gaseous fuels for heating: Ternary diagram: solid, gas, electric The Excel file used to produce these is available here: Ternary diagram Excel file User: Tom Counsell Picture updated at: Signed off by: Signed off at:```
