5 Ways To Keep Your Home Warm This Winter

Position Your Furniture In The Warm
How warm you feel in a room depends on where you are, even though air temperature is the same throughout. You will feel warmer if you position yourself closer to the inside of the house because the cold external walls are further away. So try and place your furniture next to an internal wall.
If your desk is up against an external wall so you can look out of the window your legs will tend to get cold, though you can reduce this effect by leaning a cardboard sheet against the wall. If the head of your bed is next to a cold external wall you will be prone to getting a stiff neck, though you can counter this somewhat by using a solid headboard. The best solution, of course, is a four-poster bed, but most bedrooms just aren’t big enough.
So knowing something about how heat moves can help you brave the cold winter. My experience has also shown that investigating the thermal properties of your house with an infrared camera will keep your kids amused for hours.
The key to understanding how to keep warm is the fact you lose more heat by radiation to your surroundings than you do by convection to the air. This is why your house feels so cold when you get back from a winter break, even after you’ve turned on the central heating; though the air quickly warms up, the walls take far longer to do so and may continue to make you shiver for up to a day.
Kids are like cats. :)
I like that books and art keep us warm.
Cover Your Walls
Solid brick or stone walls are better insulators than glass, but they still get cold and let out lots of heat. In my house the external walls fell to 16-17°C, 3-4°C cooler than the air in the room, even though they were made of 50cm thick sandstone.

Fortunately you can significantly reduce energy losses by covering them with picture or mirrors. Even a simple poster adds an extra layer of insulting air, raising internal surface temperatures by around 1°C and cutting lost energy by a quarter. Framed pictures or mirrors are better, if more expensive. Not being a Russian oligarch or a medieval baron I don’t have any carpets or tapestries to hang on my walls, but these would be even more effective.
Best of all are bookshelves. My partner is an avid collector and her old books make superb insulators. The spines of the volumes in our book-lined study are raised almost to room temperature, making it snug and warm. Thermally at least, printed books are far superior to their electronic counterparts.
