Have a look at this great article about Radiant Heat! https://homes.yahoo.com/news/radiant-heating-comes-of-age----after-millennia-000423339.html
  Everyone can have a nice warm floor with radiant heat!


Nice Warm Floor!

 

 

Forced Air vs. Radiant Heating

Radiant heat is 20% more efficient!

Pouring a slab or basement floor

Put insulation between the gravel and the wire mesh first.

Styrofoam sheets are fine but will break up and crack when you walk on it
and when they are pouring the concrete!

The Barrier™ under concrete thermal insulation (Available here!)
comes in rolls and is flexible and comes with an included vapor barrier!

 

 

Concrete ready to pour over Pex Pipe

After laying down the 6" wire mesh, use wire ties to attach the Pex Pipe,
so it does not float to the surface and ruin your finished floor!

Pex Pipe installed for basement slab

UNinsulated BARE PEX pipe for use insice a home in heated air space to make connections to the insulated Pex to SAVE MONEY! Can also be run between different heat exchangers with in a building or to get to and attic furnace.

This is also used for in-floor radiant heating plus slab radiant heating with 1/2" Bare Pex.. (Oxygen barrier recommended)

Smaller piping is much easier to install!

It can be purchased for as low as $39.00 a 100 foot roll (.39 per foot/ non-barrier)

Putting Pex Pipe under an existing wood floor


Pex installation withourt Spreaders! 

The double-run is a good idea but this is a very poor way to do this installation
because without spreaders, you will end up with striping; hot "stripes" or strips.

 

 

You need to use these spreaders:

Single Run Pex Pipe Heat Spreaders

But this is a poor way to do it - with only one run between joists


 


 


Pex Pipe Floor Heat Spreaders  Quad Run Pex Pipe Heat Spreaders

"Stapling" the Pex Pipe up to the floor using spreaders;
Formed aluminum sheets that wrap around the Pex Pipe,
that can be nailed to the subfloor.

 

Pex Pipe Heat Spreaders

 

A double-run is better than a single run.

A quad-run (top right) can usually be done between laminated beams
which are spaced more than 16" apart.

Pex Pipe BESIDE floor trusses

 

Here is Pex Pipe being attached to the trusses, instead of to the subfloor;
spreading heat across the truss.

 

Floor Radiant Heat Control Board

WE can have the control boards made for you; ready for an easy install.

 

This one used four zone valves (4 black boxes to right) actuated by thermostats in the four individual zones, though the blue control box (top right of photo) instead of multiple pumps, which means it is less expensive.

These zone valves can be manually activated,
in case of a board of thermostat failure on for testing.

A Taco 13 pump is on the left.

anti-scald valve or mixing valve


An anti-scald valve or mixing valve is on the bottom left and is ALWAYS NEEDED.
 
WE have the mixing valve for only $34.97
whereas many others are almost $100 or more!

NSF372 Lead Free, Sweat. 120 -160 degree @ $34.97

 

This model used a pressure tank (blue tank) to keep the system pressurized.
This is necessary for more than one floor or if a basement is used.

An air trap bleeder is top center.

Water fill supply is at top right.

This design uses an outside thermometer
to control water flow and temperature
because if the system knows how cold it is outside,
it can better contrail the temps and pump speed, etc.

 


Manifolds

 

Two zone manifold for radiant heating

Two-zone manifold

 

Four zone manifold for radiant floors

Four-zone manifold

 

Four zone hydronic manifold

Another Four-zone manifold (four loops out - supply and four back in)

This has flow meters, thermometers and valves to adjust water flow to each loop.
(I have the water flow higher to my master bath and lower in the master bedroom,
which most people want cooler, for sleeping.

This way two thermostats are not needed.

These manifolds were hidden; in a closet behind a door that matched the wood paneling, and the other two were behind vanities - one in a laundry room and the other in the master bath.

 

Six zone manifold for concrete slab

Six-zone manifold for a concrete slab in basement. Could be used for a wood floor as well.

Every radiant floor system needs at least one manifold because the water comes into the building in 1 inch Pex Pipes and is distributed to smaller (usually) 1/2" Pex at much lower volumes or speed (CFM).

 


 

We carry 4, 6, 8 and 10 loop manifolds from Rigeng!
Similar to above but metal instead of plastic!

Digital Thermostats


If your boiler does not have a digital thermostat, it is best to upgrade it to keep a tighter rein on water temperatures; to prevent boiling and Pex pipe failure due to excessive heat.

HIGHLY RECOMMENDED for BOILERS

Most inside boilers run at 180F and so you cannot have 10-20 degree swings in temperature that you would get with a mechanical or surface mount thermostat.
