Air heated floor / Discussions

...floor, would be a heated floor. here is out page all about different under floor radiant heating systems. Cooling is a different matter, some people put in air-to-air heat pumps cooling, and radiant cooling is something of a contentious topic but can work, as long as you don't 'over' cool the floor to the point where y...

...air heated radiant floors don’t overheat as much as liquid hydronic under floor heating due to the fact that air cools down much faster than water, so they tend not to overshoot the mark. Here you can compare various in floor heating - Which under floor heating system is best; liquid hydronic, electric wire or air tube...

...floor heating with air tubes such as this. But there are a lot of advantages, you can see here on our page comparing the advantages of air heated radiant floors to liquid. The air heated floors provided by Legalett circulate air in a closed loop system rather than liquid, but the coil that heats the air can be water or...

...air tubes As for distributing heat to the floor - hydronic under floor tubing as well as engineered air heated radiant floors are pumping or blowing super-heated air or liquid through floors, whereas the air at your ceiling is only slightly higher in temperature than the air at the floor. so by the time you divert it d...

...air or water and then forces it through tubing in a floor. So hydronic, air heated floors or electric mats heating systems are effectively the same in efficiency.  The differences are subtle, but in the case of the air heated floors, the heater is in the floor itself so all the heat is contained in the floor rather tha...

...air heated floors or hydronic (liquid) radiant floors, at least when they are heated with the same fuel. Meaning – a boiler heating water that is circulated through radiant tubing in a concrete floor will not be any more or less efficient that a boiler heating a water coil that blows air through a floor. The fuel sourc...

...air heated slab foundation to do an analysis of its effectiveness? I'm wondering what the numbers are on using the solar air heated collector to provide supplemental heat for the in floor heating system Legalett is known for. My question is does the extra cost of adding the solar air collector and additional cost for a...

...floor covering? As for Legalett slab on grade prefab kits, Neither air heated radiant floors or hydronic stands out as clearly cheaper to install or operate than the other, the advantages to an air heated floor is a more even distribution of heat, less risk of damaging the system during construction (no chance of water...

...heated with an air source heat pump, we don’t run the floor often, or at very high temperatures when we do. But we did choose materials that were safe for install on a heated slab on grade floor. After 5 years of use, the floor still looks great overall, but there are spots that are showing wear. In hindsight we may ha...

...air-heated floor system at least a bit to inject some heat for proper frost protection. In order for it not to compete with the heat pump, you could set the floor at a higher temperature just to activate it, just be sure to set a reminder somewhere to turn it off again so you don't overheat. This is something you could...

...floor radiant floor heating. As for the slab on grade with frost wall – an alternative to explore is a raft slab frost protected shallow foundation with air heated radiant floors, that is what we built in our recent LEED Platinum demonstration home. They can be heated with gas or electricity; we of course chose electri...

...air or hydronic), that has no impact on frost heave, nor is there any impact between the 2 and 4 inch pipes. You can read here to compare air heated radiant floors to hydronic, we’ve done both and much prefer air heated, you can see our time lapse air heated slab on grade install video here. Really all you have to do i...

...air heated radiant floors and have a few questions: What is the cfm on such a system  (per loop or run)? What temp is run through the system? Are there any other providers of such systems than Legallett in the USA? Thank you for your help,  Marty Legalett supplies air heated radiant floors with electric or water coils....

...air heated floors are just as effective and reliable as hydronic radiant floors for heating your house. This page explains the differences well – Air heated radiant floors vs hydronic, which is best?  We’re happy to help with all your questions, best to put them on individual threads to keep topics straight, so we will...

...heated floors necessary? Whether or not you need radiant heat in a slab on grade foundation floor that is super insulated depends on your climate, the amount of insulation, any floor coverings you put on, and finally how you personally define comfort. See this page that talks in detail about human comfort in homes and ...

...heated. If it isn't then I personally wouldn’t even consider it because it will be very uncomfortable, and if it is heated but the bills are sky high then  I wouldn’t either because that means it has very little or maybe even none.  On structural integrity - a house that old would probably have heaved and cracked if it...

I watched your videos with much interest but wasn't sure about the "trench" type perimeter "grade beam" in terms of supporting the house structure, and the fact that I have bedrock (Lake Huron / limestone) 18" below the surface. Wouldn't a poured perimeter wall down to bedrock be a better approach - before pouring the ...

...Air Panels to ensure a continuation of its closed loop system? In the last article about this latest demo house, it was stated that when the heated air generated from the Solar Air Panels is not needed during the summer months to warm the cement floor slab, the heated air is diverted to an air/water heat exchanger for...
