    <p>My heat pipes are not hooked up.  2 problems.  We tried one
      section and heated with 2 electric 40gal hot water tanks. 
      Electric bill was over $600 !!!!  Then the pipes were early pex
      that has set in an open warehouse ( supplier"s ) and became
      brittle soon after the concrete was poured.  I think they will
      still be reliable if not moved a lot..  Too much investment in
      that heated floor to just abandon it.  I picked up a gas ired
      swimming pool heater to use for a boiler.<br>
