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.


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 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.


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.

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.


What is one benefit of using a radiant heater instead of a convection heater?

One benefit of using a radiant heater instead of a convection heater is that radiant heaters provide quick and targeted heating to specific areas or objects in a room. This can be more efficient in situations where you only need to heat a small space or want to feel warm immediately.


Convection currents move heat more slowly than what?

Convection currents move heat more slowly than conduction, as conduction is the direct transfer of heat through a material without the material itself moving. In contrast, convection involves the transfer of heat through the movement of a fluid, such as air or water, which is generally slower than conduction.


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.


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.


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.


What are the differences between an infrared heater and a convection heater, and which one is more efficient for heating a room?

An infrared heater uses electromagnetic radiation to heat objects directly, while a convection heater warms the air in a room. Infrared heaters are more efficient for heating a room because they heat objects and people directly, providing instant warmth. Convection heaters take longer to heat a room as they rely on circulating air.


Is convection faster then conduction?

In general, convection is faster than conduction because it involves the movement of a fluid (liquid or gas) that can transfer heat more quickly than the direct contact between materials in conduction. Convection relies on the transfer of heat through the movement of the fluid, which can be a more efficient process for heat transfer over long distances.


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 is the condition for transfer of heat in convection?

Convection is the transfer of heat through the movement of a fluid (liquid or gas). The condition for convection to occur is that the fluid must be in motion, either naturally (natural convection) due to density differences or externally induced (forced convection) by a fan or pump. Heat transfer in convection is more efficient than conduction as it involves both thermal energy transfer and physical movement of the fluid.


What are the differences between a convection heater and an infrared heater, and which one is more efficient for heating a room?

A convection heater warms the air in a room by circulating it, while an infrared heater emits heat that directly warms objects and people in its path. Infrared heaters are generally more efficient for heating a room because they heat objects directly, leading to quicker and more targeted heating.


What is radialt heat?

There is a typo in your question. Did you mean "radiant heat"? If so, radiant heat is a type of heating system that warms objects and people directly by emitting infrared radiation. It is often more efficient than traditional forced-air heating systems because it doesn't rely on heating and circulating air.
