Building HVAC Science

Totex co-founder Berlin Raj joins Eric and “Overkill Bill” to unpack a single-box, hydronic monoblock system that combines space conditioning, domestic hot water, pool heating, thermal + lithium storage, EV charging integration, and backup power. Born from Berlin’s lifelong tinkering (and many shocks), the idea: stop wasting condenser heat—capture it for hot water while cooling.

The system keeps all refrigerant sealed in the outdoor unit and runs PEX supply/return to indoor air handlers (ducted or ductless), avoiding field flares and refrigerant line runs. Install looks familiar—set the pad, pipe PEX, fill a glycol loop, wire power...
