Most heating systems have two or more heating zones. The Zone Distribution Manifold (ZDM) is the place where the flow of warm water from the heating unit branches off to the individual heating zones. The fluid from the individual heating zones will then come back together to form one pipe and then go back to the heating unit to be reheated.

These installation packages have the right components that are pre-assembled in the right manner they are pre-tested, pre-engineered and the will save you many hours of site work. Often, the shipping crate will serve double duty as an attractive mounting board. Click for Pricing.


The slab distribution manifold is the place where the main pipe from the heating unit branches off into two or more circuits. It is not practical or desireable to run just one long circuit because the warm waterwill lose its heat before the end of the run and the remaining tubing will be "loafing".

The manifold should be plumbed so that the fittings are close so that the manifold will not take up too much room. For this reason, it requires a little more skill and some special jigs so that when one fitting is made, it does not damage the one next to it.

The manifold requires a very sturdy box that will serve both as the shipping container and also as a concrete form. The entire box, including the manifold is intended to be cast into the slab so that the fittings remain accessible and yet the tubing does not come out of the plane of the slab where it could be damaged. After the concrete pour, the box is rebuilt to protect the work from abuse during the remained of the construction.

Every effort has been made to ensure that the installation manuals are as easy as possible to work with and they are pressure tested at the factory so there shouuld be no problems at the site. Click for Pricing.
