PEX Radiant Heating
I just purchased a foreclosed house, which had all of the heating on the first floor removed. I decided to install a pex radiant heating system on the first floor, where the pex will be installed in circuits between the joist in the basement, below the subfloor. I purchased all of the equipment including the oxygen barrier pex, a 4-port manifold, some aluminum transfer plates and all of the equipment for the installation.
I'm trying to do as much of the work myself and I just finished installing all of the circuits below the subfloor and it looks like this: http://corvallisdowntownliving.com/S...taple%20up.png
(This isn't my actual install, but it looks identical to this with 4 equal length circuits covering the entire first floor).
All of my lines are connected to the return and supply side of my manifold, like so: https://www.houseneeds.com/shop/Imag...lds_xlarge.jpg (again, not my actual install, but identical equipment)
Next I need to hook this up to my furnace. My furnace is set up for 2 zones, one for the upstairs and one for the downstairs.
I've been told I need a mixing valve to help regulate the temperature between the supply and return lines, but I'm not exactly sure where to install this.
Can someone tell me what I need between the manifold and the furnace? If you need more information please let me know and I can supply you with pictures later tonight.
Thanks in advance for the help. -Justin.
Mixing/tempering valve. the circ pulls through it.
Another question...which I feel stupid asking but anyways..how do I thermostatically control this system?
Get a Taco zone control panel. Both zones will have their own stat and their own circulator.
