MZ install with Curvo (hr)
hr
Member Posts: 6,106
a MZ I installed today. Originally it was a 4 zone slab job. They added some upper level zones which I plated with Thermo Fin and RTI plates. So now I have two temperatures with a 3 way thermostatic to mix down the slab temperature. 130 F should handle the plate installation.
A buffer will smooth out the MZ cycles when small loads call.
I use my Curvo a lot more than the T-Drill, these days. If I were to choose a big ticket power tool investment, the bender would be first :)
It is a 120 Volt corded tool. You may reconize the motor as that used on other REMS tools, threader, etc.
It bend regular off the shelf hard drawn copper tube. Type L works best, M seems to wrinkle a little on the inside radius. It will also bend 1/2" black steel sch. 40!
I asked the factory to build a 1-1/4" die for me to try. They did! 1-1/4" L is pushing the limit, a little WD40 helps reduce the friction.
contact muproleo@sbcglobal.net for a dealer near you.

Monitor MZ
HR,
I just started puting in MZ boilers. What do you think of them so far?
Pete Caruso and his crew have been very helpfull. I love the fit & finish of the MZ. Less money than the Vitoden$. That's how I ended up selling my first one. Love how quiet it runs too.
I talked to Pete about that condensation issue. He got the bucket of limestone and went down to his basement:-)
I'll be puting another one in next week. This time I'll be using the Monitor OA reset control. I'll be the first to use one of these I think they had them made by Tekmar.

bender
That little bender would have been great when BT copper was still made!0 -
I use the rigid rathchet benders for 1/2 and 3/4\"..is there
a big difference in what they can do? It looks like the old holesclaw benders...is that electric???? Md

Something to be said
for a simple condensing heat source! I like to looks "under the hood" of the MZ. Nice, simple, easy to troubleshoot controls, no microprocessors. Even has pump, expansion tank and air purger in there!
A good boiler to use on jobs an hour or more from home
I have had one running in my shop for two seasons now(thanks Pete) very quiet and reliable.
Be tough to find a harder working rep than Pete Caruso, the "grandfather of condensing awarness"

yes, you can get hand operated rachet benders that will do the same job. Can't imagine many hand jobs on 1 and 1-1/4" type L, however!
Contact a REMS rep for a demo, you'll buy

Is there a flow benefit to bending vs. using elbows, or is it strictly a time saver and/or esthetics issue?
-kk0 -
I believe
these long sweeps present little or no pressure drop.
I know when running pex loops for radiant, even with 6" radius bends, we don't figure pressure drop through all those sweeps. Good thing, huh!

Dr. Love
We installed this MZ as a replacement for this guys old Glow Core. Outdoor reset (tekmar 260) and a Viessmann indirect.
He lives with 2 women (that's why we call him Dr. Love) and they like to walk around the house naked. When we first set up the system, we programmed the tekmar for 68° indoor temperature, but soon found out that this is not warm enough for a human body without clothing.
And you guys wonder why I like living in California so much.
Nice work, hr.

Going with the flow...
Hot Rod, just think of what you could do for further minimizing the pressure drop if all those nasty Ts were replaced with large radius Ys aimed in the right direction...0 -
How do home owners and inspectors react
to your creative use of a water heater and the curved copper? The Wall is obviously very enamored.
Does using stuff like electric water heaters for a use that they weren't designed or sold for lessen the professionalism of the job or for that matter look like something the home owners brother-in-law cooked up?
I personnaly think it is fine, I am just curious about how others react.0 -
Thanks Hot Rod!
This is going to cost me, lol, is this bender made for copper? And why did you use the tee instead of the T-Drill?
How much for the bender?0 -
love that piping Hotrod
i was looking at one of those tee machines , and that bender is sweet, i see you love your toys to huh !!, great job,...David0 -
How comes...
we see pictures of a boiler when you're on such an interesting adventure Alan?
HR, you're right about the peace of mind with the MZ. Our "Lighthouse Radiant" (3.5 hours travel time - each way) is powered up with a propane fired MZ. Not one single hiccup since its birth. When we visited the factory, there was a modulating version being tested.
Can't say the same for the tubing however - the flooring contractor turned over a staple gun to a 19-year old kid and - well you know the rest of that story. Heartbreak city. He whacked the kitchen loop no less than a dozen times. 7 hours travel time (x2) + replacement time + materials = ouch! Got the bathroom loop too. Rained down through the plastered ceilings.

Mostly for copper
but I have bent stainless tubing and 1/2 sch. 40 gas pipe. It bends that thin walled stainless and coated steel tube used in PressFit piping systems, also.
The slip clutch will let you know when it's too much metal to swallow!
I still use tees when I have to screw something, like a T&P gauge into it. Even with the new Blockade solder the copper gets pretty soft around the tee drill joint.
Price is negotiable, check with Mupro for a dealer near you. I think Able Dist in Chicago just took on the line Mike at 773-988-7649. Far less than a T-Drill costs!
Does a nice job on PAP tube, also.

\"Peace of mind\"
"when there's lots of travel time"
Interesting comments regarding an appliance from a class where service live is unknown (but problems aren't) when this particular variety is one of the earliest.0 -
When I first looked at the picture I thought it was a storage tank... I guess the UL label should be a clue that it is in fact a water heater.
I know A.O. Smith also makes insulated storage tanks.
