Here's a question for all you number crunchers out there:
Say you're designing the heating/hot water/cooking system for a small 1 bedroom house, not a new build. Which of the following is the most efficient/has smallest carbon emissions?
1. Heat (and hot water in winter) provided by wood burner with back boiler connected to hot water cylinder & radiators. Hot water in summer provided by solar thermal panels, backed up by an electric immersion heater powered by either PV panels or wind turbine backed up by connection to green electricity supplier. Cooking to be done on electric cooker.
2. Heat provided by wood burner in lounge & wood burning Rayburn in kitchen/diner. Hot water provided by back boiler on Rayburn. Cooking to be done on Rayburn. Either PV panels or wind turbine to provide for electricity needs (lighting, etc.)
3. Is there something else out there that I haven't thought of yet?
All answers greatly welcomed...
