Apropos of something else, I was moved to research my energy costs.
Night time electricity is currently 4.85p per Kwh.
Oil is a staggering 54p a liter.
Oil energy density is 37.5MJ /liter. Which with a 100% efficient boiler is still 5.184p per Kwh.
Does anyone make electrical central heating boilers?
I have UFH, which is tantamount to a big f*ck-off storage radiator anyway !
;-)
If my existing boiler was as low as 50% efficient (its non condensing oil boiler) I might expect electricity to be cheaper in the daytime a well.
Thank god for nookoleer powah!
