#OxygenNotIncluded early-ish inexpensive heat deletion: It began with a reservoir filled with ~24C water. Once the water leaving the reservoir exceeds 77C, it is emptied into another reservoir, to be used by electrolyzers for O2&H2 generation. The reservoir is set to 0/90, so that once it has emptied, it will be refilled with more ~24C water (the pipe & shutoff to the right of the refinery).

This playthrough I rushed building a self-powered oxygen machine. Most of the heat stored in the reservoir is from that ramp-up, plus some early automation. I haven't found geyser water yet, and I have no plastic yet. This solves 2 problems at once: SPOM water source, and refinery heat mitigation.
