Hi Guys,
Has anyone out there done this?
Background:
Conservation of water and energy is a big deal right? Soooo Grundfos has an instant hot water system that is only $250 that is easy to install and requires no under the sink wiring or hot water return line. It comes with water temperature sensing value that installs under the sink so that when the pump kicks(timer based on hot water tank) the valve lets all the cold water in the hot water line flow back through the cold water line. When the valve senses that the water is hot, it closes back off again, and you have cold and hot water.
What I don't like is the fact that the pump is based on a timer (set to morning or evenings when you use the bathrooms the most). And it pumps hot water to all of the house(even to the sinks that are not in use). Again a waste of energy.
I propose using more than one pump (3 pumps in my case) and install them on the 'home run' hot water lines that corresponds to the bathrooms.
Plug those pumps into an zwave appliance module (or lamp module) as these pumps use only 33 watts of power, and link it to my Z-wave switch in the bathroom.
So, when the switch turns on, the pump is activated....and I will have instant hot water.
Any thoughts /suggestions on this?
Thanks
