With winter making itself at home across the whole country, one expert says the most economical way to warm your home is to move the warmth away from your main heat source around the rest of your house.
Dr Nelson Lebo, Eco Design Advisor for the Palmerston North City Council, said the problem with New Zealand homes was that there was often one warm room with a great heater, but the rest of the house was cold.
Instead of buying more heaters, sometimes the more economical option would be to move the heat you're already generating.
Lebo said if you've got a wood burner, a great place to start was with an eco fan, an amazing Canadian invention where a fan generates power from the heat of the fire and spins faster the hotter the fire gets, pushing out the heat into your home.
The problem with older New Zealand homes, he said, was the higher roof stud where heat got trapped high up in the ceiling and wouldn't move down towards the bedrooms.
