Ok guys im gonna be putting up some staple up radiant heat under the floor joists in my kitchen. Now talking to some people they said I could just run 1/2 inch pex one per cavity(18 inches on center joists) stapled right to the floor with no heat plates and use the water directly from the boiler. No heat exchanger just add a couple valves to my return line and tap off that at 150 degree waterand add a pump. My kitchen is not real big and the total footage of pex i would be using at one per cavity would be about 250 feet. can this be done or should it be a separate loop with heat exchanger and expansion tank.
