I've been doing some research about possibly installing a heat reclaim system for my hot water heater. There are many systems out there. Usually coming in a box that houses what only looks to be a simple tube in tube condenser and a small rotary water pump. I've heard mixed reviews about the whole deal from, "It works great!!" to, "The tubes are always scaling up!". Any opinions???
Also, there are claims that it'll increase system efficiency. Kinda makes sense because of the de-superheating factor. Are there any underlying issues that I am missing?... I don't know... I guess it just seems to good to be true. Should I be concerned about any head pressure issues in lower ambient temperatures? I'm in the Orlando, FL area and I got a 3.5 ton heat pump. So in the heating season wouldn't I lose the heat that I would normally use to heat my house? I think I'd rather use the collected heat for my space heating rater than the heating of my hot water. Maybe using "O" from the thermostat to energize the heat reclaims water pump rather than the compressor contactor? Is it all even worth it?
