The mixing valves typically dont work under 0.5gpm, you would either have to drip 750 gpd or run a return loop after the mixing valve
Good info, thanks for sharingDoes anyone else feel weary using water from a hot water tank? Mine is 4 years old with a fresh anode and it's roughly 200ppm higher in tds after letting the samples sit 24 hours, all of which I'm assuming are metals.
Instead of adding hot water, I'm planning on doing a heat exchanger from the hot water tank eventually to save some electric.
That could take some work to overcome. This is why I should stay of this site. Now I am thinking about building a mixing valve setup, that I have no need for, just to see if I can make it work.The mixing valves typically dont work under 0.5gpm
Might have thought of a solution. Recirculate the outflow back to the cold side to get the needed flow for the valve to work. This would also save the energy used to heat the water by slightly preheating the cold input and not having to reheat it on the hot side. Would still need the prevalve loop on the hot side but there would be very little loss there. Might need a small accumulator on the cold side to keep the pump running smoothly.The mixing valves typically dont work under 0.5gpm
