Radiant Floor Heating System 404x40 shop
Hello everyone, I am new to this forum but have been reading it for a while now. The information is excellent, and I appreciate the professionalism here (not being a forum/message board guy due to the usual things that go along with them).
A bit of background info first---
I read here not to long ago, unfortunately it was after I purchased my radiant floor heating products, something to the effect that; "the company that you buy your components from is only as good as their after-sale service in helping you make it work properly"... like I said something to that effect.
Gentlemen, (and Ladies), I am your next victim of the growing buyer beware world of DIY in-floor heating!
Being mechanically inclined and able to do a lot in the build of own home I decided to take on our slab-on-grade hydronic in-floor heating system in a 40 x 40 shop. After pretty careful research I decided to buy my components through an internet vendor, Pex Universe, with good pricing and what seemed to be a lot of PRE-SALE tech advice in what to buy etc. And honestly, they and many other online outlets and system suppliers make a system like mine seem like a pretty simple task for the mechaincally inclined layperson.
Then I found this forum.
I noticed a number of people here who seemed to be be much like me were having problems, and the task which I was about to undertake seemed much more techinical and complex than I first thought.
I approached the product vendor for a very basic request as follows "Can you supply a basic 6 branch installation diagram for the system/components we purchased from you to ensure proper and safe installation?" Their instant first answer was "We do not design systems". A bit of knee jerk, cover our behind answer to my pretty simple question I thouhgt, but the fellow did elaborate and agree to examine my purchase orders and say, "I will look at the list you have and try to give you some basic installation guidelines." Great, so I though anyway.
Several very proffessional and polite emails, phone calls and faxes later, simply asking for a rough guide as to an order of installation... even a photo would have helped... and 2 months later, not one reply! Today we finally told their customer service rep how disappointed we are... and here I am.
I have a pretty good idea of how to put it together just want to make sure I have everything I need and have a pro verify the order of components so I do not make mistakes similar to others I have read here.
I have the following:
A 6 branch EverHot stainless steel manifold
1/2 oxygen barrier pex going in the floor, 6 branches none more than 300'
Taco 007 circulator pump
I also have an AZEL SP-81: SINGLE ZONE PUMP CONTROL (SWITCHING RELAY) FOR HYDRONIC HEATING SYSTEMS
AZEL D-508F: NON-PROGRAMMABLE DIGITAL THERMOSTAT FOR RADIANT FLOOR HEATING
Honeywell AM101-UT-1 Mixing Valve
3/4" Threaded, Spirovent Jr Air Eliminator
RX-15 Radiant Extrol Expansion Tank (2.0 Gal Volume)
I know a lot of folks don't like this but it is what I have for heating the water --Takagi T-KJr2-IN-LP Tankless Water Heater and the Remote Temperature Controller for T-KJr (running on Propane)
