Should have gotten a bigger enclosure box. Too late now...



Complete and functional control console.

I know thermocouple leads should not be extended, but I did an A-B-A test and saw only 5-10 degrees difference in the readings. All of the sensor lines have shielded cable properly grounded. It is interesting, after cramming a load of dry pine the flue temps will skyrocket, the control cuts the blower off, but leaves the damper open and temps slowly drop 100 degrees where it kicks on again. After cycling about 3 times it is pretty much a constant temp burn at 400-500 degrees. The first runup hit 750, all 3 gauges read the same thing. Don't think anything was damaged, but that's pretty darn hot.

Very impressed with how my 7400E looks. Very nice to meet Ryan and the rest of the crew at Greentech...everyone was very helpful on answering all of our questions.

I will be sure to keep everyone updated on performance. I will be hating approximately 7,000 sqft and home/business with DHW as well.

Pictures coming over the next few months as I do the install and new wood shed :thumbup: :thumbup: :thumbup:

The lower loop and pump primarily serve as the circulator only for the highest gpm possible in low gear, but the crossover allows either pump to feed either loop in case of failure, it also allows for the heat exchanger loop to be stone cold in case of too much demand or clogged filters without sending cold water straight into the return inlet -  i.e. after the HX loop has been off - it will be diluted with the circulation loop water, of course, total return temp is a factor of velocity/gpm of the HX loop so the sensors are located after the too loops converge and are mixed well. Should the total return temp drop too low the HX loop pump automatically shuts off. With the crossover, a trickle of flow can still enter the HX loop if necessary.

There is a large pressure gauge on the upper HX loop that is paramount for quickly determining filter condition and balancing the system - such as obtaining the desired flow across the DHW exchanger vs air to air heat exchangers. All this is in the name of avoiding dangerously low inlet temps in the event of an obsurdly high demand.

It is really difficult for me to explain. Power consumption and boiler longevity were high priority on the design constraints. I literally beat my head on the wall while designing this thing trying to run every scenario of heat demand and boiler limitations of the 100 different ways it could be designed. Much of it was utilizing what was already on hand to the best it could be.

And to know you pro guys build systems vastly more complex is quite humbling.

Sorry for the delay. Sometimes it will take me some time to reply, as I don't follow the forums as much as I should. The website is a working progress and not all info is finished but will be soon. Keep checking back for all specifications and all other info.

Looks nice. I wonder where the emissions numbers came out on the new line, I hadn't seen them yet. Are they on the page somewhere? Seems like with the improvements they should be pretty good.

Hi Guys,
Here is the new Pristine web page. We are still working on it but its almost complete. Let me know if you have any questions.

You're right, the hot water can be addictive.
What is the lower pump and crossover to the upper loop doing? I'm sure I'm not seeing the whole picture. I'd enjoy seeing more details of how the system all works.
Congratulations on getting fired up. You've put in a lot of work. That's a lot of threading. :)
