I installed the Grundfos recirculating pump above the water heater and it solved the problem in the kitchen immediately. Hot water in about 3-4 seconds.
Reducing the delay in the Master Bath required the installation of a second mixing valve under one of the Master sinks. Most people don't know you can add multiple mixing valves once you've installed the recirculating pump.
The Grundfos motor takes about 2 bucks a month at current kWh pricing. I'm sure there's a cost associated with heating the water in the pipes under the house, but I really didn't see a huge difference in our electric bill.

I understand that the Grundfos works with a timer. How did you set your timer so it only cost you $2 a month? How many hours a day is yours working?
