Manual J is the heating load calculation done by your HVAC installer/designer so that you correctly size the system to the building/space you will be heating/cooling.

I installed R heating in my basement 24 years ago. Two zones, each 16' x 24', heated by a 40 gal electric HWT. It has been trouble free, but no doubt a bit more costly to operate. I have been reading the previous comments regarding humidity or dampness. One of the 2 zones is my wood working shop which is as dry as a popcorn fart. I do not have any worries about fires as I would with other types of heating. The room is completely insulated and sealed. There are no heating system fans or base board heaters. I have also read about trying to reheat the room if a door or window is open. Often I will open a window at one end of my shop and open another at the opposite end which has a two speed fan. I use this for fine dust removal. (I use a cyclonic dust collector for the heavy stuff) I can run this fan for quite awhile. Yes, the room will cool down, but as soon as I shut off the fan, within minutes I am warm again.
I will be building a garage in the spring and will definitely be heating by means of radiant floor heating. I just found a heating unit, an air to water heat pump, built in New Brunswick, Canada which I hope to use for both my basement and new garage.

A good plan. Be sure to have a proper heat loss done. You will not be so lucky operating a radiant floor system with any old electric water heater above ground.

My cousin built his home and shop with radiant floor heat. Shopnis 40x60. I wish I had used the radiant floor heat. Super efficient, comfortable as hell if you have to get on the floor. No worries about carbon monoxide . He just used manifold to create zones. I could kick myself for not installing it. I am getting rid of my propane heat, too expensive in 60x80 and almost succumbed too lack of oxygen / carbon monoxide poisoning a couple years ago.
