We have an under-sink unit that has hot water ready 24/7. After hooking it up, I noticed it increased our monthly bill by about $15.

I bought a used Wemo plug for $10 and set it to only be on for 3 hours in the morning and 3 hours at night. Now we have hot water at any of the times when we actually would want it, and we aren't wasting money/energy to keep hot water on tap 24/7.

You probably only need to run the pump for 1 or 2 minutes every hour. The water in the pipes will stay warm for a while, no need to run it constantly.

Make sure to set the temperature really high if you don't run it continuously or you risk breeding Legionella.

Appreciate that; it's practically boiling.
