Radiant Heat Installation Guide: The Four Radiant Heat Installation Methods
Radiant Heat Installation GuideThe four methods of radiant heat installation are In-Slab, Joist,OverPour, and Wood Panel tracks. The method you plan to use to installradiant heat is extremely important and affects all of your subsequentdecisions. It also depends on your skill level, the layout of your home,and the materials available to you before you begin the project.Selecting a method of radiant heat installation is not to be taken lightly.The Four Methods of Radiant Heat Installation:1. In-Slab Installation2. Joist Installation3. Wood Panel Installation4. OverPour Installation
In-Slab Installation• If the concrete slab foundation has not yet been poured, then In-Slab installation is the best choice for radiant heat installation. In-Slab Installation is often the best choice for new home construction because the concrete slab has not yet been set.• With in-slab installation, the loops of tubing are configured and then laid out. Concrete is then poured over the tubing. The entire concrete slab will heat up and radiate heat into the room through hot water circulating through the laid out piping; we suggest PEX piping for this application.• The In-Slab Installation method results in the slab becoming a large thermal mass that will stay warm for long periods of time. In-Slab Installation usings very little energy and is often preferred because it can be the most cost effective method. When installing in slab, it is important to pressure test. This test lets you know if there are any leaks in your piping before you pour the concrete!
Joist Installation• The preferred method when you have access to the Joist spaces beneath your floors is Joist Installation. Before you begin, look into aluminum Joist Trak panels and tubing. The tubing will need to be pushed into these aluminum Joist Trak panels. As the panels heat up, they hold their heat, thereby warming your room.• Suspended pipe installation can also be used in joist installation in places where you do not use aluminum panels. Hot water is required in suspended pipe insulation. This water will need to run through the tubing. This method does not retain heat nor heat a room as well as the Joist Installation method with aluminum panels.
OverPour Installation• If you already have a slab, In-Slab Installation is not an option. If you have access to the joists, you can choose Joist Installation. If you already have a slab, but do not have access to the Joists, you have two options left: OverPour Installation and Wood Panel Track Installation. OverPour Installation requires the ability to raise your current floors two to three inches. This allows for an overpour of lightweight concrete, either mud or gypcrete, onto your existing slab. PEX tubing will need to be laid on your existing slab. Then another two to three inches of lightweight concrete will need to be poured on top. This top layer is important so that there is a minimum of 3/4" of an inch above the highest point of your tubing. Warming of this new floor will be similar to in-slab installation.
Wood Panel Track Installation• Wood Panel Track Installation, the last of the four methods, is your choice if you already have set down floors, can not access the joists, and can not raise your floors by two inches to three inches. This method uses wood panel track radiant heating that raises the floors half an inch. You will need wood panels and PEX tubing. An aluminum heat transfer sheet is built into some panels, such as Quik Trak panels. They can be combined to rooms of various sizes and shapes. Your loops will require both straight and return tracks.
