Answer: 
Hello Cisco Kid,
That is really not a great way, to solve that problem. If you have a hot water run that's far from your heater a 10D424 is a pump that is designed to circulate the water from your heater. simply instal it near the longest distance and it will pump the hot water from your water heater.
I hope this helps, thnaks for using Grainger Ask & Answer!

Answers

Answer: 
At 240 volts this item draws 40 amps. You may need to verify that the other items in the house will be able to operate with that amp draw. This item is typically used for a single sink and will not be able to heat enough water for a complete shower. If you need one for an entire house/cabin use, please contact us at 1-800-GRAINGER for assistance.
