Air heated floor / Discussions

...floor, invites moisture problems as it can cause warm humid air to condense and put you at risk of mold and mildew forming. Here is a our page all about radiant floors as a starting place - Radiant floor heat - Air heated, electric of hydronic, which is best?  Even in the appropriate climate it is a fairly complicated ...

...air-heated floors across Canada and the U.S. since the mid-70s, and even longer in Sweden where the company originated, so there is nothing new there; it's the addition of the solar air panels that is new at this point. We expect to see about 60-70 % of the heat load but we won't know for sure until the winter of 2020 ...

...floor I would personally want to see the utility bills to know what a winters worth of heat would cost.  And a last piece of advice - don't be instantly leery of it simply because it is a slab. As long as it is in good shape, I would consider that an asset compared to a basement.    

...floor heat in upper floors, as are other products, but to answer your slab question, I wouldn’t be using it in basements. You simply need to embed tubing directly in the concrete, no need for additional products.  We have lots of pages on Radiant Floor Heating, have a look here and you will probably find all you need -...

...air heated floor, I don’t believe there are any other manufacturers, and that is a great start to an efficient and durable home, we just built our recent Demo House on a Legalett slab air heated floor last year. I would first point you to this page about insulation – What is the best insulation for a home? In there you...

...air pipe system I was wondering if you have to vibrate the concrete mix to ensure no air pockets? What is the thickness of the pipe- sch40 or more like sdr26? How far is top of pipe from top of concrete? Yes, with the Legalett raft slab air-heated floor you need to vibrate the concrete with a pencil vibrator. The compa...

...air radiant heat system, would be about 1000 square feet. There is only one manufacturer of slab on grade form kits with air heated floors that we know of, the company is Legalett, they distribute in Canada and the US. If you provide them with final building plans and structural details they will in turn provide you wi...

...heated air panels feeding air tubes in the slab floor. Solar air heating panels are a lot less hassle and risk than solar water heating panels, and a lot more affordable than photovoltaic solar panels. We expect this to be among the more affordable off-grid heating solutions as it will only take a small PV panel to run...

...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 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...

...heated floors, furnaces, hair dryers, kettles, baseboard heaters etc.) would cost the same on a ‘BTU per watt’ scale. Keep in mind that a boiler for a hydronic floor can be powered by either electricity or gas, so any difference in operational cost would be determined by your local gas and electricity rates.
