It happen in all three mode.
Heat is conduct through wall to outside and the wind convey heat rapidly from the wall. The open surrounding is colder than the wall surface and the heat irradiate directly from wall to environment.
Conduct -> Conduction
Convey -> Convection
Irradiate -> Radiation
Conduction (through e.g. solid materials like metals that allow heat through - like a saucepan base) It is transformed into another object by touchConvection - in liquids and gases. Hot substances expand and so are less dense than cold substances. These less dense liquids and gases rise and cool ones fall forming a current. as an example, convector heaters in your home, the Gulf Stream that brings warm water from the Caribbean to Europe.Radiation - the method by which energy is transferred through a vacuum e.g. in the infra red heat energy from the sun as it travels across the vacuum of space.radiation, convection and conduction.
The most common way to provide heat in a home is by convection
Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
Heating by radiation is when heat energy is transferred through electromagnetic waves, such as from the sun to the Earth. Heating by convection, on the other hand, is the transfer of heat through the movement of a fluid like air or water. In convection, warmer fluid rises and cooler fluid sinks, creating a cycle of heat transfer.
Heat energy travels in three ways: convection, radiation, and conduction. The radiation from the sun heats the air around the house, making the walls warm. Than, the walls warm up the air inside the house. The sun rays go through the windows, which will trap heat. The heated air will rise, and stay there unless there is an escape route for it.
CONVECTION
conduction and convention is not a energy it is how energy moves and travels and warm air goes up then when it starts to cool it goes back down to cool that's why you should have insulation so heat doesn't escape. it vibrates the particles in the air this is called conduction :) hope this helps :)

Do you mean "transmitted" or "exchanged" instead of "conducted"? Conduction is one of three methods of heat exchange. The other two are convection and radiation. Conduction is heat exchanged when a material directly touches a cooler material. The atoms in the hotter material vibrate against the atoms in the cooler material, causing the cooler atoms to vibrate faster and become warmer. Convection is heat exchanged when a material moves from one place to another. In a home heating system, hot air from the furnace or radiator is blown around the house, and the house is thus heated by convection. Radiation is heat exchanged by electromagnetic radiation. The Earth is heated by light (electromagnetic waves) from the Sun.

Heat energy, more specifically you can use radiant (usually electric), Convection (forced or natural [either gas or electric]) or conduction (electric usually)

Loft insulation stops conduction and convection as the insulation which is inserted into the wall cavity prevents the particles of heat energy from traveling through the wall cavity, this stops conduction from taking place. Loft insulation also prevents convection as the cavity insulation stops the air particles from moving, therefore they cannot transfer heat and convection cannot take place.
A example of conduction is: picking up a hot bowl of soup, putting a marsh mellow over a fire, and putting ice in a HOT glass of water.Conduction: Touching a hot stove and being burned.Convection: Hot air heating/rising, cooling, and falling (same with water).Radiation: Heat from the sun warming your face.Find more examples at Yahoo Answers!
Heat loss from a home occurs through conduction (through walls, windows, and roof), convection (air drafts), and radiation (heat emitted from objects). Proper insulation, sealing of gaps and cracks, and using energy-efficient windows and doors can help reduce heat loss. Heating systems should also be well-maintained to operate efficiently and minimize heat loss.
