Title: Heat technology ternary diagram

Content: The 2050 Calculator's heat sector translates users' choices into a one of a number of permutations of heat technology combinations.  These are shown in the table below:

	AA	DD	DA	BA	DB	BB	DC	CC	CA	CB	CD	AD	AC	AB	BC Gas boiler (old)															 Gas boiler (new)	90%		20%												 Resisitive heating	10%	10%		10%			7%								 Oil-fired boiler															 Solid-fuel boiler						10%					10%	10%	10%	5%	15% Stirling engine μCHP									10%			19%	19%	24%	 Fuel-cell μCHP				90%					20%						 Air-source heat pump		60%	60%		50%		60%	58%		18%	25%				14% Ground-source heat pump		30%	20%	0%	30%	20%	30%	30%	30%	30%	25%				20% Geothermal								1%				1%	1%	1%	 Community scale gas CHP									33%		13%	30%	24%		15% Community scale solid-fuel CHP					20%	70%				45%	20%	33%	35%	63%	25% District heating from power stations							3%	11%	7%	7%	7%	7%	11%	7%	11%

To help users contextualise the choice between technology mixes, it is possible to view a comparison of the available combinations across three dimensions, useing a ternary diagram.  Two examples are shown below; the first using electric / individual / communal as the axis, and the second using solid / liquid / gas fuels.  The Excel file used to produce these is available here: [insert link]
