- The New Heatguard MultiFlex Thermostatic Mixing Valve by Cash Acme. This innovative valve increases the useable capacity of your water heater by mixing in cold water at the valve. Simply attach the valve to your water heater, and turn the temperature up to 150 F.
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.
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
mine is leaking from the union fitting. Of course you skip right over the install of that
are you going to need water expansion tank for additional pressure after mixing valve install?
Anthony Merc yes it’s code required
By raising the temperature, doesn’t that use more electricity?
+lazaro lopez yeah, I'm not sure what the justification is for the environmental claims, I certainly can't think of any.
NO . when the water is hotter you use less hot water and more cold water .
But a higher temperature in the water tank increases the rate of heat loss to the surroundings. This is basic physics: Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature. The tank will lose more heat to its surroundings the hotter it is maintained at.
You are correct, raising the temperature costs more - though I think in the end, it is cheaper to go this route, than to get a larger tank.
PS. you could add a thermal blanket to help reduce energy loss
@@SmalltimR thermal blanket does nothing, tanks are already insulated and primary losses are stack and jacket ( pipes and vents) this is a cheaper option to increase useable water if you lack space to increase the size of the tank. On demand heater us the more expensive and better option
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.
This uses quite a bit more energy. Maintaining the tank at 150°F uses approximately 60% more energy than keeping your water temp at 120°F assuming an ambient temp of 70°F in the room where the water heater is located because the power consumption to maintain temp is proportional to the delta-T. The national average in the USA is currently $561 per year in electric cost. With this system it would be much more. Rather than install this system to increase your capacity, you would be better off buying an 80-gallon tank.
There's no way this will work with a hot water circulating pump😓
Yes, it has a connection port for the circulating pump line
The moment he said shark bite fitting I disliked the video
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
If you know what you are doing with sharkbites they are fine. Like anything else preparation is most important,
We did an entire home 15 years ago shark bite, not one leak, at least yet!
@@suspicionofdeceit glad to hear it, it must have been pricey ( more pricey than buying a crimp tool for sure.
Long use sharkbite fails fairly spectacularly. Where i live is pretty hard water, the o rings get destroyed by calcium and magnesium and fail, when they do its sudden and a gusher of a leak. I hope yours continue to hold, but for reference last year i replaced sharkbite failures done by homeowners in 4 seperate instances, one was bad install ( they took the ferrule stiffener out and the pex walked out, the other 3 failed as i mentioned
