My .02. The hydro coils I have installed I have treated like I treat solar hot water installations. It will need a diversion to eliminate the human factor. I installed a heat dump, baseboard or a set of coils underground to divert to. I have used a variety of diversion options some battery direct and some more main stream. An aqua stat to a relay and a pump rated for the temperature it is about to encounter, works well with battery based. Same for a grid tied application. Steal 24 VAC from a transformer in place of the battery voltage. Apricus Solar has a HEAT DIVERSION air unit that is rated for [30] of the Apricus tubes, it will divert 30K BTU per day on an annualized basis. Basically a small radiator I have a commercial heat diversion valve that is available and opens and starts to divert at 190 DEG. F.

That sounds like an excellent idea. An aquastat controlled valve or pump that would circulate the hot water through a baseboard heater when the tank approached dangerous temperatures seems to be a perfect solution. Using a P/T valve as the only safety makes me uneasy. If it were vented to a good drain where no one could get scalded, and it almost never was triggered, it might be ok.
