The Heatguard MultiFlex Thermostatic Mixing Valve

By raising the temperature, doesn’t that use more electricity? 

I cry foul! This is a scam! I am a trained Mechanical Engineer and I can tell you this setup does nothing! ALL it does is recirculate some of the heat your water heater generates from burning gas or electricity- this heat is being "recycled" BUT it is the Same HEAT, in other words you are not making the system more efficient or produce more water from the same amount of energy input. If so then why do they always tell you to turn up the controls to 150F (Hmm could it be to produce more hot water??) Also a "Mixing" valve by definition (and design) simply mixes two streams of flluid and has NO effect whatsoever on the appaarti that produced the two streams nor does itt have any effect on efficiency. I don't know if Heatguard is a legitimate company but their product is hogwash and they should be sanctioned for making false claims that (among other things) violate the Law of Thermodynamics- you can't get "free" heat just by screwing together a couple of pipes

System looks a little to close to the Electric service panel. Thanks for the info and looking to get a mixing valve for my heater soon. And the shark bite install is a plus, not sure if I will do that however

I doubt there are any energy savings but that is not the reason, from what I have read, for these valves. Bacteria do not tolerate the higher temp, 140+, so this is done for public health reasons.

I installed one of these on my water heater and though it wasn't as easy as the video shows it is definitely a DIY project. We have had good success with this and it really has increased the amount of hot water we have. Meaning more people can consecutively take a shower and still have hot water which is what we wanted it for. One thing to be aware of is that there are two filter screens that are installed with this and they do get build up on them over time. To the point of losing hot water pressure. The fix is to turn off the water, remove and clean the screens and reinstall.

Total garbage valve with braided hose connections. Valves leak everywhere in 1 year.. install a better valve, don't use anything sharkbute or flex connections

are you going to need water expansion tank for additional pressure after mixing valve install?

mine is leaking from the union fitting. Of course you skip right over the install of that

The moment he said shark bite fitting I disliked the video

There's no way this will work with a hot water circulating pump😓

That dam drum is to much
