Anyone here ever install a radiant heat flooring system?

If so:
What was the cost per SQ FT? I know it can vary wildly depending on product.
Can you recommend a product/manufacturer?
Was it a PITA to install?
Was it worth it? - Would you do it again, knowing what you know now?
Any tips on things to look out for?
Any issues arise since you've installed it?

I'm in Texas so I don't really have that great a need for it. Actually, more or less, just something the wife would "prefer" to have if it's deemed worth it.

We're remodeling the master bath, taking it down to studs and the slab, so IF I'm ever gonna do this, now would be the time.

I put electric floor heat in my master bath. The heating elements are in a matt imbedded in the mortar under the tiles. The system for my 4x10 foot area was about $400 total. The thermostat was over $200 of that. I would put it in again and I wish I would have put it in my guest bath too. I picked mine up at home depot.

Same here. It's easy and relatively cheap. I haven't personally lived with it since I've only installed for others aside from the one I hadn't hooked up yet before my divorce.

New Englandehr heahr. I helped my older brother run lines on his garage floor before the slab was poured. We also attempted to place them in between joists for first floor. Temprature was in 40's and tubing was not very flexible. Very comfortable walking on a heated floor.

Seeing as you've got slab poured, go with recommendations from Bushpilot and newmisty.

My parents home had the radiant ceiling heat, wright-bachman home built in 1969, they all failed pretty quickly, most of those homes burned down.

Today there would have been a major class action lawsuit

I have used it in several homes, mostly in the tiled bath floors. Used the thermos oft product on the last one. Super easy to put in prior to tiling, ran extra thermocouple should it fail and honestly truly loved the result. We had a large master bath that had a vaulted ceiling 14 at the peak, so keeping heat at the floor was difficult, we used the floor heat to maintain room temp and pretty much turned the other system off... 40+ years ago while living up north the people across the street had a in slab hydronic system with valves at one end of the slab. I remember walking over after a large snow in extremely cold weather, left my boots at the front door an hour later all the tracked in snow was gone and my boots dry.
Radiant is awesome heat, truly wish we had it in our current place even here in SC.... when you feet are warm you are warm!

Good thread! I will be getting rid of the "floating floor" laminate that runs all through the house here in the next year or so and I'm going to run the mesh heating elements under the new floor. I was going to do that when we built it but the costs were ridiculous 14 years ago.
New floor will be that cushy quiet vinyl stuff they roll out that looks like wood, or stone or whatevethefeck look you want.

I already have a power source on a big breaker in the water heater closet leftover from our fun with on demand hot water. Rough math figured right around $1100 in the heating equipment from Home Depot. Flooring is like a buck sixty nine a square foot. Not too bad really.

Only thing available way back was a product called Z Mesh. It was new, unproven and crazy expensive. Many more choices now.

Was up at Brotha's house for Christmas eve party. Taking off boots and stepping on the warm concrete floor was a joy.

Had I known of the product I would have looked into it when I tiled the foyer and laundry in my split level ranch. I do have a baseboard electric heating element there but it's hidden behind a piano. Laying on living room floor I can feel the cold air coming up the stair. Previous owner installed an accordion door in doorway. Could never bring myself to do that.

Wool socks from LL bean. bout 15 bucks a pr. When the power goes out your feet are still warm. :).
I seriously wish i had done this in the tile floors I already put down. I still have 2 bathrooms and a LR floor to do though. The bathrooms will get it for sure.

I'm curious to see links to any of the newer heat systems you may have handy. TIA
I priced out the Sun touch, it's popular and priced pretty good. There was a display of it at Home Depot in Cadillac so I was able to show/explain to my wife that it's not some big scary creature it just goes under any flooring. You just set the thermostat like any other heat source. She thought radiant heat meant guys cutting trenches in the cement to run pipes full of antifreeze.

The new one I did not see to price was the Quiet warmth. That looks really good too and ultra thin.

Yeah, that's the same stuff pictured in my post. Same brand and everything. I put in their (Sun Touch) thermostat for that floor as well. Nice little unit.

Before you spend any money on fancy equipment, go outside and look at your foundation. You should not be able to see the foundation. If you can see it, go get 2" Styrofoam insulation board from any lumber yard, enough to cover the exposed foundation and at least 6" in the ground, preferably down to the frost line.

My foundation was exposed 6" above ground and I put 12" strips of foam because "frost" is a philosophical concept here. My heat bill instantly dropped to a third of what it used to be. One third!

I also realized that foam insulation now comes with foil on one side, so I got 1/2" boards and glued them to the west side of the house to reflect the intense sunlight in afternoons. Wowie zowie! I no longer get hot water from both faucets. (That is considered to be a defining characteristic of living in Arizona!)

About forty years ago, The Mother Earth News magazine was running a lot of articles about clever ways to keep a house comfortable while also reducing utility bills. Some builders in California finally did some experiments which demonstrated that the very best way to reduce utility bills was to use more than the usual amount of insulation. My experience confirms that: heating costs in February had been over $200 and this year the bill was $70.

Foil on the outside of your house might offend the neighbors, but you can deal with that one way or another. I don't have neighbors.
