What type of heat loss is reduced by carpets?
Convection , Because it traps air , the thicker the carpet , the more heat you save
How has the microwave oven been improved since 1946?
Other than aesthetics, the biggest changes have been the sources used for the heat. They've gone from wood, to coal, to gas, to electricity, to microwaves, to convection. With each change in heat source, safety has been improved as well as insulation and efficiency.
What are examples of conduction convection and radiation?
Conduction is heat transfer by bringing two systems at different temperatures into physical contact. The molecules of the warmer system bang against the molecules of the cooler system more energetically than vice versa, consequently the energy of the warmer system gradually transfers to the cooler system until they come into thermal equilibrium (same temperature). You get conduction through a system if the edges of the system are at different temperatures. Convection occurs when flow of a fluid at a higher temperature into a fluid of lower temperature. This can either be "forced convection" - requiring a pump or fan, or "natural convection". Where the movement is due to buoyancy effects due to the difference in density between warmer and cooler fluids; as air or liquid heats up, it expands and becomes less dense, which causes it to rise. It is replaced by cooler air or liquid, which is then heated as well.This is why we heat liquids from underneath, and why your house will be warmer if your heater is on the bottom floor. Radiation is the flow of energy as waves through space (and, in some cases, matter). Some examples of radiation are visible light, radio waves, and radiant heat. That's how the heat of the sun gets to us.
Is radiant heating more environmentally friendly than central heating?
Yes Radiant heating is more environmentally friendly than central heating. You will find that out after you start saving money on radiant heating. Your Welcome.
What is more efficient heat pumps with or without gas back-up?
with gas back up . a heat pump alone ,will not be able to extract heat efficiently when it reaches it's economic balance point in its region of operation.
Convection currents move heat more slowly than what?
radiant heat
What is the difference between radiant heat and convection heat?
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
How efficient is radiant floor heating of a patio floor which is outside?
Efficiency has to do with the amount of work done and the energy it takes to do it. If you want to heat the great outdoors, or parts thereof, there is no more efficient way than radiant heating.
Radiant Heaters More Energy Efficient Than Forced Air Heat?
Radiant heaters supply heat directly to the ceiling, floor or walls of a home. They use radiant heat transfer, which is heat moving directly from the hot surface to the objects or people in the room. This is the same effect as when you can feel the heat of stove burner from across the room. This type of heating is more energy efficient than forced-air heat because no heat is lost in the duct work. Since there is no moving air, it is better for people with allergies.
Is radiant heat better than a traditional furnace?
In my opinion, radiant heat is better than a traditional furnace. You have more control over how much heat you want, and where you want the heat. Using radiant heat is also more cost effective.
What does radiant heating do that saves energy?
Radiant heat is an excellent way to save energy. The heating system lays beneath your floor and the heat radiates up. It is more energy efficient in that there is more area radiating heat than other heating otions and thus quicker heat returns. This causes your heating system to run less and save you money and energy.
What materials are more efficient in maintaning heat?
Insulators are more efficient at maintaining heat.
What kind of energy heats your home in the winter?
Heat energy, more specifically you can use radiant (usually electric), Convection (forced or natural [either gas or electric]) or conduction (electric usually)
Why are convection ovens more efficient at cooking food?
Convection ovens cook more efficiently by having a fan motor circulating the air in the oven. The end result is even heat distribution.
Is radiant floor heating recommended for the bathroom?
Radiant floor heating is an excellent choice for bathrooms. It creates more of a spa environment. They are cost efficient and have thermostat control.
Can radiant floor heat alone is enough heat too heat up a house by itsself?
it depends of your house. if it has more than one floor then it might not. it also depends on how many rooms has radiant floor
Is lighting a candles wick with a match a conduction and convection?
it could be either convection or radiation that can light a candle wick with a match.The match stick does not retain enough heat by itself to light a wick by conduction. The burning match though gives off enough heat to incandesce the air around the match into a flame. By contact of this convective hot gas (flame) with the wick the temperature of the candle wax can be raised to the ignition temperature. By holding the match close to the wick, without the flame contacting it, the radiant heat from the flame can vaporize and ignite the wax as well. The closer the flame to the wick the more radiant heat can be transferred.
