Heat is energy, or rather the transfer of that energy from one body to another. This transition occurs through conduction, convection, radiation and many other interactions. It is a process not a property. Radiators heat a room through convection. This diagram shows how this happens.
Insulation also plays a part in how effective our homes are at heating up. There are many material you can use to insulate a home with. These include artificial materials such as glass wool and urethane foam or natural materials such as sheep’s wool and straw. If we can hold the heat in better this will help combat the amount of energy we currently use to heat our homes as less energy will be needed.
This picture illustrates the way we lose heat from our homes. Remember that heat is a process not a property and therefore uninsulated homes are just heating the outside instead of the inside. Below is a thermal picture of the difference in heat loss between an insulated home and an uninsulated home.
The level of heat distribution in the insulated home is far more effective. Instead of having one part of the house which is warmer than the rest, warmth runs through out. This will have an effect on the temperature that we have the thermostat at, as we won’t put it on higher so that colder parts of the home get warmer.
