Do you live in a poorly insulated home?
Many of us do, costing us thousands on energy bills each winter.
IFL Science offer some understanding on how to keep warm in the cooler months.
Because we lose more heat by radiation to our surroundings than by convection to the air, your house feels cold when you get back home each evening, even after you’ve turned on the central heating.they suggest that even 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! This is why poorly insulated houses can be several degrees colder than a fully insulated one.
They offer four simple ways to overcome this and minimise your energy bills:
- Close Your Curtains At Night – During the day, your windows let in more radiant energy than gets out; sunlight can enter through the glass, but the window is opaque to the infrared radiation trying to escape. At night, however, single-glazed windows can get extremely cold. Even double-glazed windows aren’t great insulators and can fall to around 14°C. This results in energy losses of 50-100 watts per square metre, equivalent to running an old-fashioned light bulb. The best way to prevent this heat loss is to close your curtains and lower your blinds immediately after dusk.
- Cover Your Front Door – Doors can let in draughts, and being thin and sometimes glazed can be very poor insulators, falling to 10-15°C on cold nights. Covering your door and the surrounding wall with a thick lined door curtain can eliminate pretty much all the heat loss. The best way to prevent this heat loss is to close your curtains and lower your blinds immediately after dusk.
- Use Screens – If you can’t reduce all the heat loss from your outer walls you can still shield yourself from the cold by using fire screens. A screen will keep your back warm while radiation from the fire will heat up where you are sitting.
- 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.
