Work on our green remodel begins next week. There are 101..maybe 1001!…things to consider. Fortunately our local utility provider PG&E runs a regular series of workshops and events. Today’s focused on water. I met some interesting folks including the CEO of Metlund, makers of “Advanced Conservation Technologies: D’MAND Hot Water Systems”:
At the push of a button, the D’MAND® System circulates the ambient temperature water in the hot water pipes (water that is normally lost down the drain) back to the water heater. This occurs up to 80% faster than just letting the water run down the drain—the usual scenario. Depending on the plumbing layout, the route and time can vary. The Metlund D’MAND System moves the water so rapidly, that hot water arrives at the fixtures before the heat is lost through the pipe. Continued…
D’MAND looks like it would play very well with our planned hot water system which will combine rooftop solar thermal system,
an on-demand electric water heater,
and a large well insulated storage tank.
Many other interesting efficiency-related systems on display. I’ll blog more over the next few days.
