The dimension of the heaters are 32" x 20" and come with protective wooden heat guards. These are the easiest heaters to install into any new or existing sauna cabin. Simply hang them on the wall in the same way you would a picute frame. Each heater comes with ready to connect wiring. The heaters can be connected to an existing sauna controller or wired directly to a power switch similar to a house light switch. IR heat is more like a light and as such most people choose to use an on/off configuration rather than a temperature controlled switch.
You can quickly turn a small space such as a closet into your own infrared sauna! The guide line for selecting the number of heaters is minimum 15 Watts per 1 cubic ft. For example a 3' x 4' x 6' space = 72 cubic feet (3x4x6). This area would require 1080 Watts, or 3.6 heaters (always round up) so 4 x 300 Watt heaters would be ideal for this size area. This guideline assumes a heat temperature requirement similar to a traditional Finish Sauna.
These IR panels are available in both 120VAC and 240VAC. However if the Mercury controller is to be used (which requires 240 volt service), the 240 version of the panels should be selected.
