We are on oil and are looking for our ideal solution - mains gas is in the street, £1500 to connect up (long drive..) We've got lots of spare PV output (on a sunny day) and an immersun unit -love it) We've got adequate area of land.
Maximum loft insulation, cavities filled on 1/4 of house, 3/4 of house solid walls, suspended wooden floors.
So our choices are:
Air Source Heat Pump
Condensing Gas Boiler
Ground Source Heat Pump with slinky coils (Not doing a borehole, way too expensive)
Thermodynamic Panels
Large Solar Thermal Array (we have the space) though poor angle of incidence
Log Burning Back Boiler
Biomass
We really don't want to redecorate the whole house as it's also got the small (not micro) bore piping to about half of the radiators.
So we really want a solution that can economically give us a high heat output for the exisitng radiators.
The high output Daikin and Panasonic ASHP's spring to mind, and possibly a large solar thermal array, however yesterday never got about -4°C here and today wont either.
At this instant 9:30am overcast, 13th December 2012 we are breaking even on generation / consumption of the PV
Now, seeing as we are struggling to come to a BEST solution, it gets difficult to recommend as the majority of our local domestic renewable energy marketplace will have similar challenges.
