Furnace, woodstove, heater
It is the ratio of room sensible heat to the total heat.
Well is the question the total amount of heat, or total USEFUL heat? In general, a wood fire burns a bit hotter than gas- hence the wood fired pizza ovens. Hoever, gas fireplaces usually have a heat exchanger that draws in room air, warms it, and returns it to the room. It has less air going up the chimney than a wood fireplace (a major point of heat loss) The chimney of a wood fireplace may be more massive brick, which will hold heat after the fire burns out.
the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.
In order to maintain good air quality you need return air ducts for the furnace. The return air intakes also help balance the temperature differential in the room, return air also helps maintain a safe temperature for the heat-exchangers with out the return air helping reduce the temperature around the heat-exchangers thermal overloads would trip out and shut down the furnace and the danger of rupturing the heat exchanger which would allow combustion exhaust and carbon monoxide entering in to and mixing with the supply air making a deadly situation for the occupant's.
this is called a heat exchanger with an open campfire it may not be a physical object with an electric heater it may be miles away at a power plant
by going in a dark room and see if it have lot of heat to light up the room
A room can heat up without a radiator or heater through natural heat sources such as sunlight streaming in through windows, human body heat, heat generated by appliances, or insulation that traps and retains heat within the room. Closing curtains at night, using thermal curtains, and ensuring good insulation can all help increase the heat within a room.
heat flows
Heat naturally rises in a room due to convection, which is the transfer of heat through the movement of air or fluid. This means that heat tends to move upwards towards the ceiling in a room.
If a room is extremely well insulated and the wattage of the bulb is greater that the wattage heat loss then, yes a light bulb can heat up a room. The time that it takes to heat up a room would be considerable.
A heater heats up a room by converting electrical energy into heat energy. This heat energy warms the air in the room, which then circulates and raises the overall temperature. The heating element inside the heater, usually made of metal coils or ceramic plates, is responsible for generating the heat.
the heater may be turned on more people more heat if window opened it gets colder and less people in the room less heat
An electric fire heats up a room by converting the electric energy into heat energy. The electric current flows through a heating element, usually made of metal coils, which then radiate heat into the room. Some electric fires also use a fan to distribute the heat more effectively.
As the indicator liquid in a thermometer gains heat when a room warms up, it expands, rising up higher and indicating the new, higher temperature from the increasing heat in the room.
A fireplace heats a room by conduction as the heat from the fire warms the surrounding air and nearby objects. These objects then transfer the heat to other objects through direct contact, gradually warming up the entire room.
One lamp won't do much. I have 10 and my room is always really hot when they are all on
