Hydronic Heat | The Basics – Overpour
Author: SteveH | Category: hydronic heat, hydronic heat basics, hydronic heating systems, radiant heating systems
In a hydronic heat overpour or topping slab installation – radiant tubing is installed on top of an existing slab or sub floor with wire mesh, plastic clips or a track system. A thin cement slab is poured over the piping. The typical thickness is 1 1/2″ although other thicknesses are certainly possible.
This method is useful in retrofits over existing slabs, sub floors, and also post-tensioned slabs. If you are able to adjust for the door, cabinet andhydronic heatts, this is another great way to add hydronic heat to your existing home.

HI,
I HAVE A THREE STORY CONDO BUILT ON A CONCRETE SLAB. THE FIRST LEVEL IS: GARAGE, LAUNDRY/FURNACE ROOM. THE FAMILY ROOM IS APPROXIMATELY 15′ X 24′ AGAIN BUILT ON A SLAB. THERE IS A 4′X6′ LANDING BETWEEN THE FIRST AND SECOND FLOORS (6 STEPS UP TO SECOND FLOOR AND 6 STEPS DOWN TO THE FAMILY ROOM. THERE IS ENOUGH ROOM UNDER THE LANDING FOR A SMALL WATER HEATER FOR RADIANT HEAT. I NEED RADIANT HEAT BECAUSE THIS ROOM IS UNINHABITABLE IN THE WINTER. (HEAT VENTS IN THE CEILING PLUS AN OPEN STAIR WELL. I WOULD LIKE SOME SORT OF SYSTEM WHICH WOULD BE COVERED BY A PERGO STYLE FLOORING BUT THE STAIRS LEAD DOWN TO THE DOOR TO THE LAUNDRY ROOM: THE FAMILY ROOM BEING TO THE RIGHT. MY CONNCERN IS THE 3/4 OR 1″ STEP UP TO THE NECESSARY RADIANT HEAT FLOORING. THIS WILL BE A DIY UNDERTAKING SO ANY SUGGESTIONS YOU CAN OFFER WILL BE GREATLY APPRECIATED.
THANKING YOU IN ADVANCE
