When my vinyl floor will need replacing I plan on using a Carbon Heating Film developed by the Koreans, when on shore power or using the generator. They use these under floors and behind walls to provide radiant heat. A post from several years ago installed the film along the walls in the over cab area of the TC to provide more warmth during winter camping.
Made by
RexVa, called XiCA heating film imported into US Canada and Europe, but not highly marketed.
A later generation version
PTC Heating Film, a positive temperature coefficient heating film with reduced power consumption and less likely to overheat.
Background and installation videos can be found on
YouTube A quick search on Google found a vendor on
EBay and a
vendor in PA.
Probably better to go with a retailer who you could call and ask questions so I'd contact RexVA and ask who the importer / distributor / retailers are in the US.
