Engineer on the loose

Constantin

... I like the clear piping system, the excellent support work, and the webstone flanges. Judging by this WIP picture, the "after" picture will be stunning for first-time work. The thermostatic valves are a nice touch, though I doubt that they will ever be necessary. But so what, it's like insurance, you never hope to need it.

However, unless you have also taken a combustion-class or two, I would urge you find a local contractor to set up the boiler for clean, efficient combustion. The tools to do that right are expensive, and the training essential. Good luck, congratulations, and I hope to see more in the future!

Phase 1 of my own system

This is my first install, my own house. I'm not a tradesman, just an engineer. There is a Munchkin T80M off to the right (on the other end of those 1.25" lines). This is a primary/secondary w/ 3 radiant zones next to each other on the secondary so far. The primary is at the very bottom with the secondary feed pump near the bottom by itself. The munchkin has Vision 1, but, just in case the munchkin looses its' mind, the thermostatically controled valves are set to 140.

The wiring is just cobbled together to make it work for testing, not done yet.

The indirect will be added to the left end of the primary (future). The empty webstone flange on the right is for another indirect for the 165 gal bathtub (future).

Comments, feedback? Please be nice.

I think you did a fine job!!!! Did you get the Munchkin vision 1 pre-programmed???? I thought only allowed vision 1 contractors to access the parameters?

Very nice

Very nice

A can of Brasso will make that system shine!! looks real good ....David

Vision 1

I programmed it. After talking with HTP and asking the kinds of questions that convinced them that I'm not going to burn the house down, they sent me the book. I will go to training though when they do another session up here in the middle of nowhere.

The next step is to wire the system "properly". I do industrial robotics and believe you can't wire anything without DIN rail and cage clamp terminal blocks, and have both ends of every conductor labeled.

Do Munchkins

lose their minds? It looks very nice. Are the thermostatic 3-ways necessary?

very nice,

an engineer who can use tools? i'm doubly impressed..i just had to throw that in there ;-O

Losing its mind

I have no evidence that Munchkins glitch any more often than any other microprocessor controlled device, but I'm a mechanical engineer so I'm trained to believe any piece of software with more than 13 lines of code in it has a bug somewhere.

The thermostatic 3way valves are really just a belt and suspenders thing, the penalty for failure (overtemp in the whole radiant floor) is just too severe.

The other half of the reason the thermostatic valves are there is that there may be cases where I need to run the indirect for a really long time and want to be able to heat the house as well. This allows me to run 180 deg water from the muchkin for the indirect and allow a radiant heating zone to turn on for a little while (without outdoor reset functionallity of course).

Tools

As with many people who have spent too much time and money at school and not enough doing "real" work, I can only claim enough skill to make what I want without hurting myself. Don't ask how long this took me.

Startup

Actually, I didn't run the gas line or do the startup. Leaking water I can handle, but leaking gas is another level. I hired a real technician to run the gas line, fire it up for the first time, and see if anything needed adjustment. It didn't.

Yes, there are some of us out here who consider ourselves "energy professionals" but have not worked in one of "the trades." When I was in building maintenance the cost factor had me doing a lot of things myself that homeowners would not (and should not) do themselves. I always tried to completely understand the piece of equipment I was working on and the theory behind its operation; then do the most complete and professional job I could. That still applies to what I do at home for myself. And yes, I do spend a lot of time on projects (that would put me in the poor house if my living depended on it). But things work, and work well - and are SAFE.

I know the pros have lots of stories about homeowners and maintenace goofballs that have done incredibly stupid things. But there ARE some us who will take the time (and get the training) to do it RIGHT.
