HeatTrak Power Unit for Residential Snow-Melting Mats
Each set of Residential HeatTrak Mats (sold separately) requires one power unit to connect the system to an electrical outlet. The power unit connects your system to a 120V electrical outlet and allows power to flow to the mats.
You can connect up to 15 amps on a single power unit. Each Residential Walkway Mat is 2.5 amps and each Residential Stair Mat is 0.6 amps. So you can connect either 5 Walkway Mats, 15 Stair Mats, or any combination thereof. If your connected mats exceed 15 amps, you will have to split up the mats and add a second power unit to plug into a separate outlet. See Buying Guide for more information.
