My one story house currently has radiant heat in the ceiling. This system was initially installed abour 40+ years ago. The area heated is about 1500 square feet. We currently have a screened porch which is about 12x12 next to our kitchen. The floor of the porch is concrete, and is about 4-5 inches lower than the floor of the kitchen. We want to re-do our kitchen, including converting the porch into a insulated, walled kitchen table area. The house is currently not air conditioned. Would it be practical to consider extending the radiant heating system to heat the area that is currently a porch? Could a radiant heat system effectively be installed on top of a concrete slab where 4-5 inches of clearance exists, and still have the floor flush with the current kitchen floor? Could we also add an air conditioning system? ( there is an unfinished basement under the entire house, except the porch - there is also an accessable attic, but I'm guessing the radiant tubing in the ceiling would make it difficult to use the attic for an air conditioning unit? Would we be better off installing a new forced air system to heat/ Air condition the house? The current burner is 15+ years old - Weil Mclain. We also will be opening up some walls and putting hew beams in to support the more open floor plan. Will this opening up likely lead to problems with the already installed radiant tubing in our ceiling? Thanks in advance for your opinions. The radiant heat is comfortable, but I am also concerned about the ceiling age + stress on the integrity of the ceiling that removing walls could cause.

there are new alternatives to radiant. with product lines to back it up. air conditioning .... is now referd to as Space conditioning...this uses radiant to take the heat out of a space and save it for some other time or purpose...i am in alaska and have installed york air conditioners :) it gets hot here with 24 hours a day sunlight. space conditioning ....cheaper way cheaper operational costs and maint... it isnt something that works like magic. there are laws of physics it operates under like every thing we see day to day. interested? leave a message on my question on self locking sheet forms for radiant pex tubing ...on this site.
