No he wasn't, but he seems like a fairly bright guy, and he may have already realized that he was wrong since reading my last post.
I see I'm going to have to take things reallllllllllll slooooooooow for you though.

In reality it wont be anywhere near 100%

Here's a link. And a quote from it:

Air conditioners and heat pumps are heat engines like the refrigerator. They make good use of the high quality and flexibility of electric energy in that they can use one unit of electric energy to transfer more than one unit of energy from a cold area to a hot area. For example, an electric resistance heater using one kilowatt-hour of electric energy can transfer only 1 kWh of energy to heat your house at 100% efficiency. But 1 kWh of energy used in an electric heat pump could "pump" 3 kWh of energy from the cooler outside environment into your house for heating. The ratio of the energy transferred to the electric energy used in the process is called its coefficient of performance (CP). A typical CP for a commercial heat pump is between 3 and 4 units transferred per unit of electric energy supplied.

There is no law of physics which applies specially to TEC's.
Heatpumps can move more energy than they consume.
A TEC is a heatpump.

A Drift-0.8 TEC is called a 172 Watt TEC because its Qmax spec is 172 Watts.
A TEC's Qmax spec indicates the maximum heat it CAN pump with a specific hotside temperature, (typically 300 °K) under ideal conditions. (typically 300 °K)
A Drift-0.8 can actually pump more than 172 Watts at hotside temperatures higher than 300 °K.

Uh huh.
