I've been reading here for a while but have not posted yet. Figured its time to participate. I purchased the 80 in the spring for a great price.... dealer old stock.. needed it moved blah blah...
I originally had my heart set on the smaller ridgewood, but this one came up at just over $1200 cheaper with HX,pump,Plate exchanger, mixing valve, insulated pipe and enough 1 inch pex,fitings and clamps to cover my installation.
Anyway.... I poured the slab and buried the lines in early summer and had a friend with a skidsteer get it off my trailer and set on my slab. After the flurry of work, life put the brakes on the project for several months. A few little cold snaps have inspired new activity.
Well yesterday I cut into the forced air system to install the HX.... that was harder than I thought it would be. I ended up with my manifold, feed and return lines inside the air return and the rest of the HX 2 inches above the ac coils. It has made for a fairly stealth install though. This week I will run the lines back to the plate exchanger and punch through the exterior wall to make my final connections.
I have some new hot water lines to run as I will be feeding 2 hot water heaters and will be running an exterior hot water line to melt ice and snow from the car this winter and to feed hot water to my pressure washer.
That's it for now.... I should be ready to fire it up in a couple weeks and I will try to update often over the winter as there seems to be very little information on this small unit and I'm sure someone will be interested.
