The bigger more affluent houses also had "staff" to bring in the coal and keep the fires stoked.Because we have Victorian houses we should live like Victorians? Be freezing cold in the winter except when 2 foot away from the fire. They also tended to wear heavy house coats indoors, have wingback chairs to contain the radiant heat. The reality is that is not the way people live these days.
They also used massive amounts of polluting coal to heat their houses.
