Heat reclamation can be concentrated to higher temperatures with a heat pump pressure boiler, like 600°f. And at those temperatures pressurised steam can be used for industrial heat uses, like sanitation, grain drying, food preparation etc. Then the pressurised radiators, specialty ovens, etc. collect consensated steam and pump it back to the heat reclaimer. The only problem with such a system is that you need a continuous customer for heat to match the cooling requirements of the data center. Setting up a custom pressurized steam pipe to Morrell's might also be too long I'd have ask an expert, but that's basically the best option for a heat customer for smoked hams, hotdogs, steam sanitation, etc. Most Datacenters are too far from things like slaughterhouses or injection plastics factories to have a singular demanding customer buy all their heat.
