How does radiant heating system work?
There are many different ways to use radiant energy to heat your home including radiant flooring, radiant electric heating, radiant tiles... The site in the related links has tons of information on radiant heating. Technically, "radiant" heating is used to distinguish from "forced air" systems. In a radiant system the radiant elements emit heat and in an forced-air system the furnace heats air, which is then moved to where the heat is needed. A radiant system can be electrical, hyrdonic or steam-driven. For instance, a hydronic boiler heats water to about 180 degrees and uses circulators (forced hot water) to move the heated water to a finned-tube, floor-tubing, wall-tubing, or cast-iron radiator, heating the radiator, radiating heat into the room. The cooled water then flows back to the boiler to be heated again.
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.
Which method of heat transfer is the most important in a structure fire?
convection
What is a difference between heat energy and radiant energy?
Heat Energy is one FORM of Radiant Energy...it is not different.
Why vacuum flask keep cold liquids cool better than hot liquids warm?
It is due to heat transfer by radiation. You must first understand all objects emit some radiation, even room temperature items, but hotter items release greater radiation. With a hot liquid, the vacuum flask is releasing heat via radiation (radiant heat) outwards into the surroundings, the surroundings mostly absorb this radiant heat, therefore the radiant heat is constantly lost to the surroundings. However, with a cold liquid the radiant heat is transferred from the surroundings to the vacuum flask, where the vacuum flask is a relatively small "target" for the radiant heat to strike. Therefore the cold liquid only receives a small amount of radiant heat from the surroundings and thus changes temperature more slowly. Think of it this way: The surroundings is a very very large "target" for the heat released from the thermos to strike, while the thermos is a relatively tiny target for the heat from the surroundings to strike, thus it is easier for the thermos to lose heat than it is to absorb heat from the surroundings.
Is radiant flooring an option if you have an existing concrete floor?
Radiant flooring is an option if one has an existing concrete floor. The radiant flooring system is installed underneath the concrete floor to heat the concrete.
What type of flooring is best over radiant floor heat?
Ceramic. Ceramic.
How can one install radiant floor?
There are different methods of installing radiant flooring depending on whether you prefer under floor radiant heat or an above floor system. There are many videos on YouTube that can help with your installation either way.
Should you install a programmable thermostat for radiant water heating?
I think if you are using a radiant heating system like warm board that can respond quickly to changes in temperature then a programmable thermostat makes sense. However if you are using concrete slab radiant heat, which takes a long time to heat up and cool down a programmable thermostat will be less efficient than leaving it at one set temperature.
How does radiant heating actually work?
Radiant heating is also called "underfloor heating" or "ground heating." There are small electric coils (they're kind of the shape the wires in old fashioned lightbulbs) under your flooring (they lay down a concrete or hard surface, then the coils, then your flooring, which should be measured to a specific thickness). It works from the ground up to heat the walls and surrounding area, making you feel warmer.
Is it really worth me getting a radiant heater?
yes, radiant heaters are wonderful. they are radiant and they give off heat. if you want warmth you should definitely invest in a radiant heater. you will be so glad you did.
In what form does radiant heat transmit?
Radiant heat transmits in the form of waves.

DIY Electric Radiant Heat Flooring?
Choosing electric radiant heat flooring can be a convenient and cost-effective way to heat your home. Many flooring systems are now available that homeowners can install themselves. Here are a few pointers on these systems and their advantages. Most electric radiant heat flooring systems are designed to be laid onto the subfloor. This is done in one of two ways: laying a pattern of loose wire over the floor held in place with tiny clips, or laying a plastic or rubber mat or mesh with the wire embedded in it over the floor. Loose-wire installation is good for areas that have odd shapes or curved walls. Installing mats is much easier and similar to laying vinyl floor tiles. Loose-wire electric flooring is further held in place with lightweight concrete or self-leveling compound. Electric mat flooring is laid on a layer of thin set or stapled to the subfloor. In most cases, electric mats are covered with thin set or self-leveling compound to provide a smooth surface for your floor covering. Also, subfloors must be insulated to prevent the electric heat from moving downward rather than up into the room. Concrete subfloors will need an underlayment of cork or insulation board. Some mat systems come with a special layer of aluminum that reflects the heat upward. Although almost any floor covering can be used with electric radiant heat, ceramic tile or other “stone-like” materials are recommended. Ceramic tile stores heat longer and can heat a room more evenly. Wood laminate and engineered flooring can be used but the manufacturer’s specifications for maximum temperature must be followed strictly in order to prevent warping and preserve the warranty. Carpeting and hardwood flooring are also possible but the thicker these materials are the more they act as insulation trapping heat in the subfloor. Although radiant floor heating is not the perfect heating solution in areas where electricity rates are highest, it is generally no more expensive than leaving your lights on all day for six months out of the year. With its low-cost installation and nearly-zero maintenance, electric radiant heat flooring can provide you with warmth and comfort for the life of your home.
How to Retain Radiant Heat Using Simple Methods?
The natural source of heat that wood fires and the sun’s energy emits is called radiant heat. Radiant heat has a natural quality to heat any object that come in it’s path. Though this is a very economical way of heating our houses compared to using electric heaters, it is extremely difficult to retain radiant heat after it enters the house. Below are simple ways in which radiant heat can be easily maintained. Keeping the windows tightly shut and sealed will help retain radiant heat. During the winter, windows should be sealed with shrink wrapping kits that ward off the winter winds and cold temperatures. The shrink wrapping kits consist of plastic and adhesive tapes that can be stuck to a place using hair dryer’s heat. These kits are usually quite cheap and available at most home improvement stores. Another option is to buy and use reflective window treatments. Reflective surfaces can be on the inside or outside of the window surface to reflect radiant heat. Reflective surfaces will prevent heat exchanges. Apart from windows, another easy exit for radiant heat are rooftops. Heat rises and if there are attics, heat will be lost if they are not insulated. By insulating attic floors energy loss can be kept to a minimum. This will also help in lowering the utility bills. Carpets provide good protection from cold surfaces and also retain heat. Wooden floors are poor in retaining heat and laying carpets will prevent heat going out through the floorboards. Maximum retention of radiant heat can be achieved by using solar thermal radiant flooring. For this, collection stations have to be designed around the house which will focus the heat directly to the flooring space and thus heat the house. This method is expensive, but it is a onetime expense that can greatly reduce monthly utility bills and is nature friendly. There are other options like using aluminum foil sheeting on the inside of the roof to act as a barrier to heat exchange. Some weatherizing programs that are provided by local authorities are eligible for tax credits. In conclusion, maintaining radiant heat in your home not only keeps you warm but also saves you money.
