Or you can do what I used to do to process color film in my bathroom. Either get a controlled temperature faucet OR (what I did) get a decent reasonably fast acting thermometer and fill the sink slowly enough that the overflow will handle it (or partially crack the stopper) while adjusting the hot and cold to get a given temperature. I used to use a glass with the thermometer in it to start under the faucet - as the sink fills it takes longer to compensate for differences. I think this was the secret to making this process reasonably easy. This worked quite well enough to get the photo processing chemicals to 77F (as I recall). It was a PITA to adjust the first time, but after that I marked the faucet control knobs and adjustment was pretty quick. If you are going for a long run and are worried about wasting water, you can get it started this way, use the water to transfer to whatever you are sticking the brew cup in and *then* put in the heater and adjust it to where it just comes on. I did that here with the fish tank - I caught a day where the ambient temperature was what I wanted the fish tank to be - stuck the heater in the tank and adjusted it to just come on and the tank has maintained the temperature (every time I ever checked) very closely. Just a thought!
