Those of you who read this thread know I sort of sit, apparently "dormant" for a while, letting things soak in, until I decide to move on something, or until a moment of inspiration hits.
I've been just sitting on the concept of a heat exchanger for, what, about two weeks, now. One of my lessons in life lately has been to slow down, streamline, and MAKE SURE I need to do something, buy something, before I take the leap - a sort of reverse-squirrel process. Right now, I especially want to make sure I need to buy something, or that I'm buying the best choice.
I've been stewing on the heat exchanger idea, and haven't moved on anything yet.
This morning, I start obsessing on the idea that if I'm going to do it, I really need to know it works, and I need to know how well it works. I just do. I mean, why do something if you don't have a means to measure the effects?
So I start pondering how the beejeezuz I could set up my system, cheaply, such that I could actually measure the efficiency of my heat exchanger.
And then, it comes to me...
Two valves, and a loop of plumbing is all it will take. Maybe 5 bucks and 5 minutes of plumbing extra in the project.
I'll make a diverter circuit in my supply line, with two valves, one to the heat exchanger branch, one to the diverter loop branch. By selecting which of the two is open for flow, the water will either go through the heat exchanger and on to the Water Factory, or it will bypass the heat exchanger, and go to the Water Factory. In a second, I can do one or the other, by adjusting the valves.
Then, it's a matter of running the Water Factory, and taking an end point stream and measuring the temperature under the two conditions.
So, this makes me happy.
