If you look at a simple termperature response curve of a various radiant elements, you'll note that different efficiencies (measured in terms of radiated and convected J/KWh) can be obtained in via different designs. They dissipate energy fast as well. Author: Messages . Any one run into that before, Just wanted to add an important warning to this post. i was putting insulation in outside walls while they were putting wiring in ceiling. Do I need to do anything with the wire if I do clip it, beside insulating the end? Never did much to try and repair the cuts knowing how difficult it would be to find them.

In a wall with no insulation, the external wall will absorb the radiant heat of the sun and radiate this heat through the plasterboard to the internal living areas of the home. Radiant ceilings accelerate fast, when needed, to meet a big change in heating load. Again, there's a large difference between heating the same air mass (electrical vs gas central furnaces) and localized zone heating that relies more on radiant heat transfer than convected heat transfer, which is more efficient and is noted to equate also with higher levels of thermal comfort. We pay 0.075$ kw/h.

This is his classic book on Amazon http://www.amazon.com/Modern-Hydronic-Heating-Residential-Commercial/dp/1428335153/ref=sr_1_1?ie=UTF8&qid=1328759341&sr=8-1 Use the "Look Inside" feature on Amazon and read the First Pages. An average room can take up to 2 panels for sufficient heating. Here's an excerpt from a paper I have (which references many other studies). But you cannot compare forced air gas heat with electric radiant based on the cost of electricity and gas alone. Hydronic systems also have pretty low distribution losses, and almost all of those losses accrue inside of conditioned space and are not fully "lost" during periods of real heat load, even if they're not heating the exact zone calling for heat. Ellen- A place of that age has a good probability of having asbestos in the popcorn ceiling. But for homeowners who want warmth more than anything else, the reason to choose a radiant system is that its design and technology always ensure maximum comfort.

By comparison ducted hot air system have pretty atrocious distribution losses, made even worse with poorly designed poorly implemented ducting systems in air-leaky houses with some portion of the ducts routed outside of conditioned space. The main hall, where the seating areas are, is heated via forced air. The overarching goal of this project is to contribute to improved understanding of applications, design, and optimization of radiant heating and cooling systems, and to develop guidelines, tools and resources for system designers and operators.
