Are you talking about just using a standard tank type water heater vs an Instant hot water heater?

Do you have gas available at your location ?
Here is my setups with a 40 gal, there's a few guys running tankless water eaters on here aswell.

Sorry about that "but" it is buy. I'm looking to build a 40x60 pole barn with a 20x60 living area to one side.I'm going to put radiant heat in the floor of the 20 x 60.I was looking at the water heaters and didn't know whats the best to use.A water heater that cost $3000 or one that cost $500.Also they will have to be either propane or electric.

After much research, I chose to use a Takagi NG tankless heater in my 1200 sf pole barn in SW Pa. Works great.

We live in southern Oregon (lat. 42 degrees north) where winter temperature are 20's/40's (night/day). I put four solar hot water panels on the roof of my 40'x 48' shop and they will deal with most of spring and fall heating requirements, but for winter I need more. My storage tank is a residential 50 gallon electric hot water heater which I rewired so I could fire up both heating elements simultaneously. For the first three years I was using about $150/month ($0.09/KWh) of electricity to supplement the solar panels during winter. I bit the bullet and bought a Unico reverse cycle chiller (a heat pump that produces hot (or cold) water.) Now my heating cost peaks at $45 for the coldest month. The payback time is about 5 years. I keep my slab at 68-69 degrees. Anything more and it too hot! I insulated 24" vertically around the periphery of my slab, but not under it.

"We live in southern Oregon"
Every radiant floor design is location and application specific. What "works" in Oregon, is completely irrelevant here in Minneapolis for instance. Or, in a retrofit we are working on in Buenos Aries, with foot thick un-insulated walls and a climate without snow.
First the heat load, then the equipment. You will want a sealed combustion water heater since most steel buildings are very tight and can make a very unhealthy atmosphere for working or living.
An ERV is a must unless you like to keep windows open year round.

Electric or Gas? For $3000 consider a Reverse Cycle Chiller (heat pump that produces hot (or cold) water), It will cost you 1/3 - 1/4 the energy costs to operate over an electric hot water heater.

We need to see photos and a project write up please. I am often bothered by the fact that the mainstream application of residential heat pump technology has been for air heating. The technology is really maturing with efficient inverter motors and low cost. However, these same technologies just haven't been applied to heating water for domestic or heating applications.
I just ran a 50 amp circuit to the location for my boiler to heat the 1800 SF of shop. I hate to do it but the only reasonably common way to heat water is with resistance heat. 500$ hydroshark boiler, bleh.
John, I am living in a very similar location/climate as you [Boise Idaho]. I have some questions:
1. Why did you not insulate under the floor?
2. Why not a NG powered solution?
3. Do you have any pictures of your setup, I am very interested.
4. Is your building walls and roof insulated?
5. Do you use the reverse cycle chiller in conjunction with your solar heater when talking about the $45 bill in the coldest month?
6. Do you use A/C? If so what system and what costs to run it?
