We are beginning to go into winter now. Wellington and our lounge measures 14 degrees with our wall thermometer. We generally don't use any heating until it is dinner time or after dinner time and that's the lounge and then when we are in the bedrooms we use the heaters althou I have resisted in using them.
I know it is this NZ kiwi way. In the past NZ homes were not insulated and until now they are and the single heating requirement is a fireplace or a gas heater or a heat pump but do even new homes require bedrooms or hallways to be heated? So it is the same old right jumping from room to room and to a cold laundry / bathroom. Wearing puff jackets and thermals in the day time and hot drinks to keep warm, haha. Again like many NZ households we took up the initiative and installed a single heat pump in the lounge and added ceiling insulation but we didn't do wall insulation due to a lack of access.
