Hot Tips for Staying Warm and Saving Energy

More ways to save on your power and reduce energy bills.

When winter comes, we dig out our heaters, have longer showers, and snuggle up with our hot water bottles, all in an attempt to upkeep our precious homeostasis. These household habits cause a steep increase in our energy bills and related environmental damage. Here are’s tips for saving energy over winter, and the rest of the year for that matter.

Heating and cooling

  • Sunlight — Utilise sunlight to heat your house - it’s a great natural alternative.
  • Curtains — You want lighter curtains to let sunlight in and free temperature exchange between indoors and out; heavy curtains maintain internal temperature and block incoming sunlight.
  • Doors — Opening the doors over summer is a great way to let in fresh air to cool the skin. In winter,however, open doors are an efficient way to lose heat and waste money. Make sure to upkeep entryways with solid doors with minimal gaps. If that means those silly door snakes, then so be it.
  • Windows — Even a window slightly ajar can drastically reduce warmth.
  • Selected ducted — Ensure you close the ducted heating vents that lead to unoccupied rooms.
  • Close doors of spare rooms — Similarly, close the doors to unoccupied rooms. Heating these is a waste of energy.
  • Layer up your clothes — This one almost goes without saying, but chuck on an extra jumper instead of chucking on an extra heater interval.
  • Layer up your bedding — Add an extra blanket or keep your socks on when you go to bed. It sure beats the cost (and associated emissions) of an electric blanket.
  • Close up the fireplace — The fireplace is a wind tunnel of sorts. And when it is not in use, it is allowing cold external air into your home.
  • Ceiling fans — When you can, use the evaporative cooling benefits of fans rather than air conditioners since fans are energetically rather cheap. Many ceiling fans also have options to rotate clockwise or anti-clockwise, drawing up or blowing down heat, change appropriately for the seasons.
  • Insulation — A well insulated floor, walls, and ceiling all contribute a lot to heating and cooling — why not consider some insulation plans.
  • Heaters — Move them away from windows where their heat is easily dispersed. Also, use a small fan or space heater if you're only heating one room, the room you're in.


  • Shower head — Ensure the various taps and shower heads in your house are as efficient as they could be.
  • Hot water system — Make sure your system is correctly sized to suit you and your family. There are many sizes of hot water systems and yours may be ill-fitted. Alternatively you can visit our page on solar hot water units.


  • General appliances — Turn them off at the power points. Even when they’re not ‘doing anything’, they’re using energy, especially toasters and kettles.
  • Kitchen appliances — Dishwasher: Use your ‘ecomode’, fill up completely (it can handle it); Microwave: Use for reheating foods only, thawing can be done with foresight; Fridge: Don’t put it next to your oven… And speaking of your oven, opening the door costs a drop in precious degrees (up to 15℃), use that tiny window, y’all.
  • Hot water system(a) — If you're going away from the house for some time, a few weeks, switch off your hot water system.
  • Hot water system(b) — Did you know you could adjust the temperature of your hot water system? Why not set the heat to between 60℃—65℃. This will avoid burns to small children and reduce your overall power consumption.
  • Water pipes — Rubber tubing can be applied around copper hot and cold water pipes to maintain their temperatures.
  • Washing machine — Use a front loader, use cold water, wash with a full load, chuck your jeans in the freezer to kill microbes, they scarcely need cleaning.


  • Turn down heating overnight — If you’re layered up in bed (clothes and blankets) and the house is already warm, you should be able to keep that momentum going through the night, so you can turn off the heaters.
  • Turn off the heat when you’re not home — Similarly, the heat will not dissipate in your absence. The house can be kept toasty till your return. Having heaters on while you are gone is a fire hazard to boot.
  • Turn off heat during the day — Let the Sun do the work. And since you’re a mammal, you’re likely to be more active during the day and generating your own internal heat.
  • Seal all exits — Seal shoddy seals. That includes window panes, fridge doors, gaps under doors, you name it — make a crack-based investigation around the home.
  • Snuggle — Water bottles, wheat bags, and hubbies (or just one, if you’re that way inclined). Yes, there are many ways to stay warm throughout the night.
