Hi, i have a small bathroom, probably about 100 sq ft. that sits right above my oil burner. My house has baseboard heat. I am thinking hydronic is the way to go because of this. I can do plumbing and am pretty handy, but never did it before.
What is the easiest and most efficient way to do this? Will i need baseboard heat in my bathroom along with the hydronic flooring heat? What parts will i need? I am looking for some specific details, never did this.
Also, in my situation, is this better than electric??

Hi Mayhem, you will get more advice over in the "Boiler-Steam and Hot water systems". The pros over there may not watch this group. If a Mod doesn't move it, just re-post over there.

i just got a quote for $297 using the Easy Heat wire system with thermostat. I am pretty sure i can install this. The salesman said i do not need a GFCI cirucuit to run this, even under the shower.

What about keeping a small piece of baseboard heat from the boiler in the bathroom. Can i use both?

The heating forum is a better place to ask this. I've gotten a lot of good help there.

In a nutshell, I think the big issue for you is if you can access the area and run pipes. If yes, a retrofit shouldn't be all that bad. However, you will probably want to hang the bathroom off of an existing zone, so you will need to know where the supply and return are to splice in. BTW, you can splice in with 3/4" PEX which is easier to work with, just make sure you use the correct PEX for heating and not potable water pex.

GFI is a good idea in any near-water application. If you need to, you can get a GFI breaker for your panel.

Sounds like you're considering 2 different systems: Hydronic (PEX tubing from boiler) and Easy Heat (electric cable). Hydronic will be cheaper to run and more expensive to install. Both will work. Your choice... and you certainly DO need a GFCI with the Easy Heat. It's usually built into the thermostat. You probably also want and my be required by code to have a dedicated electrical circuit.
