In-floor heating / Discussions

...heating and cooling) is a very well-insulated and airtight envelope, so it doesn't require a lot of heating and cooling in the first place. It is also fairly open, and it has hydronic radiant floors for backup heating, so a ductless mini-split heat pump is sufficient. It also depends on what you call comfortable - if y...

...heating, or the air system that Legalett uses. I am also wondering how much rebar should be in a slab on grade floor and if it's okay to have the perimeter touching the ground without any insulation beneath it?  The most cost-effective system to deliver in-floor radiant heat would in your case depend on how big it is, ...

Hello, I’m designing a FPSF in Southern Vermont (AFI 2300).  I want to fully insulate the radiant slab by including 4″ XPS under the footings but this seems to conflict with the FPSF principle of relying on heat transferring through the footing to stabilize the ground temp.  My next thought was to use the FPSF design g...

I'm looking to buy a house build on a slab-on-grade . What should I be looking for in terms of insulation? Thanks, Terry Where is the house, and do you know how old it is? Those two things would offer a first indication of how well it is insulated, depending on what the Building Code requirements were in that location ...

...heating system that is built directly into the slab? Radiant heating is very comfortable, and there are really only minimal differences between the comfort that different systems will deliver. I would base my choice of systems mostly on cost and ease of installation, along with design considerations of the house. Warmb...
