LAVA® Radiant Panels Support

Common Support Questions

How far from the radiant panel will the heat substantially radiate and where should it be aimed?

Radiant heat travels through air, and typically heats up objects closer to the panel first and then the rest of the room later. Infrared heating from the panel can be easily detected from about 3-4 feet. Ideally, the radiant panel should be aimed onto the area with more use, since that will be the surface that will warm up first.

How does one know which size panel is correct for a room?

If you have a room with "average" insulation levels, take the square footage and multiply it by 7 or 8 watts per square foot. That will provide a good estimate of the watts needed to heat that space.

Is there a concern with children touching the radiant panels if they get too hot?

Radiant panels using infrared heating can get very hot on the surface (up to 248° F). For safety, it is recommended that your radiant panel be mounted out of the reach of children.

Do you have a calculator for monthly radiant panel heating cost?

We do not have a Radiant Panels Running Cost Calculator. However, this can be determined easily by taking the panel’s wattage, dividing it by 1000, and then multiplying the result by the local kW/hr cost – then take this hourly cost and multiple by 730 hours to get a monthly estimate.

How quickly does the radiant panel heat up?

The startup heating time for this infrared heating system is approximately 5 to 10 minutes. However, your room will not feel warmer immediately because the cold objects in the room (furniture, walls, ceilings, floors, etc.) need to warm up first. Once these surfaces are heated via infrared heating, the warmth will spread throughout the room.

Can a LAVA radiant panel be recessed into the wall so the front surface is flush with the wall surface?

We recommend an open 1.4" (3.6cm) space around the edge of the LAVA radiant panel for air circulation and easier installation. UL requires that the On/Off switch must be operable and visible, and no flammable materials may be used around the LAVA radiant panel.

Where should I mount the Lava radiant panel?

Please abide by local electrical code guidelines. Lava radiant panels may not be installed in "wet locations" such as showers or saunas. The top, bottom, and sides must not be closer than 12 inches from any other object or surface in order to effectively radiate heat. The Lava radiant panels may not be placed behind doors. We do not recommend installing Lava radiant panels on ceilings.
