I am copying this setup for my floor heat/domestic hot water system and I don’t understand why the cold water coming in is tee’ed and going to the mixing valve and to the hot water side. To me it seems like it would cool off the water before going to the heat exchanger.
To me it seems like it...
It’s been a while since I have posted an update. I’m still plugging away on this thing. The summers are very busy for me so progress was slow. Here are a few pictures.
The siding is done and boy did that take forever!!! I still need to do the little bit of stone work on the front to match...
I have been working in the shop here and there. I have some lights up. I think they are in their final spot. I have been moving them around playing with different layouts. Testing it during the day and at night.
I also got power to the sub panel. The inspector gave me the go ahead to power it...
The R value of closed cell spray foam is about 7 per inch. I have 2 inches and then the 1.5 inch foam board I put up between the purlins is an R-6 so I’m at about an R-20.
I got my spray foam done today. Very happy with the results. Went 2 inches thick.
Now I need to finish the wiring and figure out where I am going to place all my lights. Then I will drywall the ceilings and do some blow in.
I haven’t updated in a while, I went on a cruise and spent some time in florida for spring break. Things have been slow on the barn. I cleaned up the yard that looked pretty bad. I have spray foam coming on Friday. I have to get all the windows installed or at least framed out before he gets...
I worked the weekend on the roof. I had to stop early Saturday for a st. Paddy’s day event my wife and I had to attend. Last night I worked until the sun went down. I only have left about a half of a square and then the ridge vent on one dormer and the last third of the main peak.
I don’t mind. I found two inch foam at a farm tile store. It is 2” with an R-10 value. It was right around $18 a sheet. I was going to go to the big box store and get the Dow pink board but this is the stuff the concrete guys told me to get.
The pex I just picked up at Menards. I used 2400...
I am still plugging away. Roof is done finally and in the process of getting concrete done. Concrete crew should be be done prepping Monday. I have a few days to run all the pex for the floor heat. Pouring Thursday or Friday.
Back on the roof, we had a break in the weather after about a foot of snow.
I have pretty much laid every shingle by myself. My dad has been a huge help. He made a lift to get the shingles up to the roof and occasionally gets up and helps. The forecast is looking good to get this done...
