Tubing installation (from Vanguard HRH Application Guide):
Single zone, single loop, Comap radiant system (courtesy of RL in Wisconsin, 11/2002)... note the thru-the-wall supply/return piping and nice plumbing work:
Single zone, 4-loop, Comap radiant system (courtesy of GD in Minnesota, 1/2003)... 80 PSI in the tubing and ready to pour the concrete! Note the piping connected to the supply manifold for the pressure test (100 PSI). Great rough-in work!
Radiant slab, ready to pour (courtesy of Denis J. Gielas in Pennsylvania, 9/2003): "I used the rough in insulated slab method and found it to install very easy. Attached are some pictures of my Garage area that I ran four separate 240' loops."
Single zone, single loop radiant slab (courtesy of DD in Iowa, 10/2003). Take a close look at the loop layout... the warmer supply end makes a quadruple run along the entire perimeter at close tubing spacing to offset the greater heat loss at the exterior walls.
24 Port Manabloc Plumbing system (courtesy of JB in North Carolina, 12/2003). 3/8" Pex (used for the low-flow fixtures) is connected to the Manabloc using MXLSA24 port adapters.
Multiple zone pump radiant configuration using HRGP1 circulators and HRTV5 thermostatic mixing valves (courtesy of CL in Camano Island, Washington, 02/2004). System also includes a Munchkin 199M boiler, several Comap manifolds and a Taco pump controller. This is one of the best looking installs we've seen!
Professional Manabloc system install (courtesy of plumber RK in Perry, Florida, 10/2005). Note that either MBB2 mounting brackets or simple 2x4 blocks can be used to secure the Manabloc in a studwall. Very clean install!
This 4-Zone Comap HRFH system install is laid out very well (courtesy of CC, 2/2007). All 4 zones are plumbed with HRTV4 thermostatic mixing valves and HRGP1 zone pumps, controlled with a HRCVP434 zone pump controller and dual water heaters.
Retro-fit MXBD18-3 Manabloc installation courtesy of SB, Norfolk, VA 10/2008. This creative plumber kept all the existing fixture valves and adjoining copper stubs and just ran new 1/2" pex to all stubs using XLC33F sweat adapters. Existing copper piping had multiple grounding wires so a grounding bar was added to keep the entire plumbing system properly grounded.
We would like digital photo's of your radiant system or Manabloc system, just email them to us at cs@mvsupply.biz and we'll post them for everyone to see.
