LPG is horrendous there is a reason Calor will give you a boiler and a tank FOC
oil neednt be bad
Ive had both several times in rentals - always on modern boilers.
youll find most of the horror storys are still running v.old boilers/raeburns/agas im sure or are operating it like gas
Oil boiler should be a back up for your wood burner IMO. cold winter mornings and hot water.
we spend 600 quid a year on oil. and 150 quid a year on wood and we keep toasty. - 1950s 3bed semi on top of a hill in an exposed location north east scotland.
We do how ever have a programable timer thermostat (essential with oil) cavitywall insulation - 300mm loft insulation + insulated walls in the internal walls(not the roof) in the roof space where the bedrooms are. drylining on the gable end that gets hammered by the wind - fitted blinds and curtains , double glazing and underfloor insulation. - makes a huge difference - can heat the whole house with the woodburner.
dont think it will be like a new build house and that you cannot use oil heating on low all the time to keep a base line - youll heamorage oil.
qwerty - this is not the case. 3ft thick walls suck ALOT of heat out the room - ive lived in a modernly restored cottage - 2005 it was done to latest regs and still it took 2 or 3 days to get it comfortable place to be without the heating being on all the time - the stone just had to get warmed up.
Im all for solar thermal but solar PV im not so sold on - the life time maths doesnt add up for me yet. Solar thermal i intend to add later when i do the extension - stick in a thermal store and hook it all up. I speced my boiler with this in mind.
