Manhours – Therma-Floor is sold by authorized dealers and installed by factory-trained installers. But a dealer may sell you the product to handle small jobs, like a bathroom, for instance. This entire system can usually be installed by one person, with the exception of mixing and pouring Therma-Floor. Of course, it depends on room size. You may need an electrician to feed the power and do the final hook-up. The following manhour estimates are based on the WFK 120-volt electric system and experienced installers (having installed the product at least three times). They include the WFK (but not the thermal mass and finish floor covering):

• 12 square feet – 1.5 manhours

• 18 square feet – 2.0 manhours

• 32 square feet – 2.5 manhours

• 48 square feet – 3.0 manhours

• 62 square feet – 3.5 manhours

• 94 square feet – 4.0 manhours
