Stirring things up

That time of year and to be frank, not a day to go outside. 
The sharp eyed amongst you will spot the electric heater - why you say when you have underfloor heating.
Well our air source heat pump broke down in ealry November - just out of warranty of cojurse -  and the requisite part cannot be sourced until January. Ther local plumbers have kindly put in heaters to keep away the chill.
