I never got around to installing my mix valve haha. It will scald you. We have young kids and don’t have an issue. It comes in handy getting a head start on anything you are boiling water for tea, spaghetti, scalding chickens, ect.

When putting the tape on the threads, you have the tape coming off the roll, from the top of the roll. (Roll is being held vertically.) If you turn that roll over, so the tape is coming off the bottom of the roll, it is a lot easier to keep the tape tight as you apply it.

Oh man. As soon I saw that heat exchanger. I honestly thought you were making beer. I am a homebrewer and we have the same thing but we call it a Wort Plate Chiller. Instead of heating a liquid, we use it to chill down wort or unfermented beer. Also a counter flow chiller might work for you. 😁 just saying.

In my next house im definitely going to get a outdoor wood boiler. Miss the wood boiler content from the farm.

You ever notice the point in the blue part of the flame from a propane torch? That point is the hottest part of the flame.

Very interesting stuff! Learning all kinds of things. Thanks for sharing! 🤠

good video, I am enjoying following this project. I agree with what you say about copper vs pex

famous last words " I have plenty of time before heating season" lol. Frost here tonight, going down to 2C or 35.6F.

Nice job! Sorry about the leak. It's after the fact, but a quick & simple way of leak testing the heat exchangers before installation might be to pressure up one side (shell or tube) with an air compressor and attaching balloons to the other side fittings. Any leak would blow up the balloons. Of course you'd need to make up the fittings for this test. Temperature could also affect the leak, so you 'd want to go above the normal operating pressure for the pressure test.. Looking forward to the next vid. Many blessings.

My reminder for direction of tape, time to put on tape, time =clockwise

GREAT video,loved it Todd 👍🙏🇨🇦🇺🇸

thanks for the video and information.

Potable water.... So..We love your videos. Please don't hate us. Understand the difference between potable and non-potable. That heat exchanger is way too small. Glad it failed. You should not have potable and non-potable water going through an exchanger which can fail and contaminate your water. Plastic is plastic. If you distrust it, don't drink out of anything plastic. Pex is safe. Love your copper soldering skills. It is cheaper than push to connect. However, don't forget to pay yourself for your time. Keep up the good work! ♥

Awesome video, would like to see another video of hooking up the new one!

I already saw in the comments section, but thought I would repost. Using a brazed plate heat exchanger on a domestic water application is not a good idea unless you are using a double wall unit. The magic of a double wall unit is if there is a hole in the plate the water will drip between the plates in a cavity (without fluid) and onto the floor so you will know there is a hole in the plate, and the fluids will not mix. Over time the solids in the water will wear through the plates of the single wall unit, the fluids will mix and you won't know. There are a few manufactures who make double wall brazed plates. (Alfa Laval, bell and gossett, etc.) With that being said I would make sure the new one you get is a double wall brazed plate.

Great job very interesting maybe the heat exchange might seal it's self ??!!

Never leave solder in pipes or connections as this will introduce turbulence and the water going by will eventually cut thru the pipe. Also when cutting any pipe you must chamfer the inside to make a smooth transition from one connection to another for the same reason. Pex is the only way to fly as copper is not forever and if joints are improper will leak over time. I have seen copper become less than paper thin and leak from elements in the water causing corrosion. Copper had its heyday but not anymore.

Order a mixing valve. I went cheap and all you do in the shower is constantly tweak the water from too hot to cold. Remember mama ain’t happy ain’t no one going to be happy.

Thanks for the video. Sorry to see what happened. Do appreciate you try to save an extra piece.

Cool
