Radiant Floor Heat for Retrofit Applications


The RetroHeat floor heating system provides you with the means to enjoy radiant heat without having to tear out your existing floors. If you can access your floor joists from below, you can install RetroHeat and supplement your home's heating system as well as increase the value of your home.


The RetroHeat heating element is effective for virtually all types of floors and is easy to install. The thin, lightweight heating panel conveniently staples up between your floor joists and then common batt insulation is installed underneath the panels, directing the heat upwards to efficiently heat the floor. The under floor radiant heat system is UL approved and carries a generous 10-year warranty.

RetroHeat for All Types for Floor Surfaces

The RetroHeat system is one of the best values for installing radiant heat under any existing floor surface, including tile, hardwood, and carpet. So, if you have open access to the floor joists from below, you can add in-floor radiant heat to your bathroom, kitchen, bedroom, or living room floors.


RetroHeat efficiently heats your floors and is easy to install. When installing the system, the heating panels are cut to their proper length, then stapled in between the floor joists. Heating panels are available for joists with 12", 16", and 24" spacing. (Measurements are taken from the center of once joist to the other, not the distance in between the joists.) After stapling the heating panels between the floor joists, the electrical connections are made and common batt insulation is installed underneath the panels to direct the heat up through the floor.


The under floor heating system consists of heating panels, connection materials, and unique digital thermostat that includes a 16-amp GFCI breaker and floor sensor for accurate programming.
