Title: Hooking up floor heat
Post by: shoebox on February 08, 2015, 07:18:30 AM
what I have is a one loop from own coming into the house to the force air system.  How would I tap into that loop to run my in floor heat system?  Be for I had 2 loops coming from own one for force air other for I floor heat, but have since put in a new line(just one).  Plus I believe it would b a closed system now, so would I née expansion tank?

you should get a water to water heat exchanger to separate the open system to the closed system. then get a secondary loop and come off that loop to the water to air exchanger and put a mixing valve in for your infloor heat loop.

What kind of floor heat is it? If you're using something like Ultra-fin you can run your water directly from your boiler without the need for heat exchangers or mixing valves.

If you had it running as an open system before there is no reason you can't again. Just put two tees in the line close together.

This is assuming you already have a pump and mixing valve for the floor heat. If not you will need a pump too.

Exactly how mine is set up.  Works great for me I've never had an air in the lines issue.

If you are going into concrete, m1sacs is right and the radiant should be anti freeze'd as well as mixed down in temp. Long story short, more info is needed.
