Necessary part 2021?
I was going to just set my aquastat for 120 degrees but saw numerous cases explaining why it is better to over heat the water and mix it with cold using one of these. So, I did the extra plumbing and now, my aquastat is set around 140 and this mixes it with cold. Easy install and seems like a quality item. It is made in China but I haven't had problems with their manufacturing recently. The fittings were threaded nicely. I adjusted it easily and now have great domestic hot water.
