Radiant Heating - Why do You Feel Warm? The Best Most Efficient Heating System

What makes you feel warm on a sunny day in the summer? Radiant heating or radiant energy is usually recognized as the oldest form of heating. It provides the best comfort and is the basis for all types of heating systems. Radiant heating is "radiant energy" being emitted from any heat source. Radiant heating is the effect you feel when you can feel the warmth of the sun or a hot stove top element from across the room.

Radiant heat is widely known as the most comfortable and efficient heating method you can find. Some of the advantages of radiant heating are: it is usually more efficient than baseboard heating and almost always more efficient than forced-air heating because no energy is lost through ducts and other transfers. This technology can be used for both heating indoor and outdoor areas. These heating systems work by supplying heat directly to the floor, to panels in the wall or to the ceiling of a house. Because the radiant heating will make you feel warmer when you are in a room, you can have the thermostat at a lower temperature and still feel warm.

The feeling of warmth is the absence of heat being pulled from your body. If the walls, floors, and ceilings around you are warm then they are not pulling heat from your body. Then you feel warm. Your body is not giving up heat to them.

Because of this radiant heating systems can provide massive energy savings of more than 10-30% in most residences, and sometimes up to 60% in shops, hangars and warehouses. Radiant heating provides even warmth with no cold spots within a room. That provides a comfortable environment that cannot be matched by any other type of heating system.

New radiant systems are currently designed to run cooler than they did in the past. The water supplied to the systems will generally range from 90 to 140 degrees. Remember radiant heat can travel in any direction and is unaffected by gravity. Radiant heating systems will allow you to be more comfortable at a lower thermostat setting. Radiant heat will warm the closest and coldest mass, which then radiate heat throughout the space evenly. Radiant heating will give you the most consistent room temperatures from floor to ceiling when you compare it to any other heating system.

I need to talk with someone re using Radiant Pro software. Keeps coming up with wrong numbers


Can you name the company to which you'd like to speak? You posted your two questions under Watts Water Technologies. There are several software packages that include the words "Radiant" and "Pro" in the name.

Can you bring up the "About" box in the program?

I have a 7yo Kenmore Elite gas dryer w/no heat. I tested all the possible culprits with my ohmmeter. I found the ignitor was not glowing so I replaced it. Now it glows but I still have no heat


The glowing if the ignitor indicates that the circuitry is good but the flame/radiant sensor is bad and/or one or both of the gas valve solenoid coils are not working. The flame/radiant sensor bypasses one the solenoid coils then when power is applied to the ignition circuit, the first coil opens the first valve, the ignitor glows and the flame/radiant sensor gets heated. It's contacts then opens when heated enough to unbypass the second coil and allow the gas to flow and be ignited.

Make sure the flame/radiant sensor is properly in place and aligned with the ignitor to allow proper heat sensing. You may check the continuity between the sensor's contact terminals as the ignitor glows. At first, the terminals should read close (zero resistance) and then open (infinite resistance) after about 30 seconds or so. If this is not the case, the sensor is not working and must be replaced.

The solenoid coils, one with 2 prongs and the other has 3, sitting on top of the gas valves must be both replaced if the flame/radiant sensor turns out good. But before doing so, make sure to run a test with the dryer completely assembled because sometimes the gas do not ignite when the dryer's cabinet is open. This is to prevent unnecessary replacement of the coils.

Feel free to update us about the result and if you need further advice.
