I haven't used the heater yet, I do have a heated throw rug which works really well and have been using that instead on cold mornings and evenings. The first thing I do is get dressed in a few layers and put on some warm socks or slippers, then turn the kettle on to make a hot drink. Lately I have been wearing a double lined hoodie jumper and a beanie around the house to keep warm!
It doesn't get really cold in Sydney in the mornings, Au. Every day I'm staying home (which is most days,) I turn the bar heater on before I get up to make up my big bowl of cereal with rolled oats, diced dried fruit, fresh fruit, almond meal & lots of other things on it, refill hot water bottle, & turn off the heater, as I climb back into bed, with my breakfast! (I can only mention this from a Sydney residents point of view!)
