At 1000℉ (811K) the maximum achievable COP against an ambiental (300K) source is about 1.6, limited by the second principle of thermodynamics.
And that's the absolute theoretical maximum, you would be happy to breakeven in practice. Unless you have access to waste turbine exhaust, geothermal water, solar collectors or something along those lines, I don't see any practical application where the marginal energy savings would recover the capital costs of the pump at 1000F.
But hey, they have software modeling and venture financiers, so I'm sure they are not overselling it and it's all excellent and double plus innovative.
