I'm looking into installing the AO smith voltex heat pump heater. I just had a plumber here who knows how to install it and said he wanted $1500 to install it. My jaw dropped. :eek: Is there that much work involved with these things? ]]> Geothermal cholcombe http://ecorenovator.org/forum/geothermal/2191-heat-pump-water-heater-install.html http://ecorenovator.org/forum/geothermal/2188-gage-set-hose-backwards.html Sun, 29 Apr 2012 10:36:11 GMT I installed my first mini split it did not go as planned.

I did a nitrogen purge and then a pressure test at about 25 psi.. I then vacuumed the line set and indoor unit for several hours.

I then released the refrigerant into the lineset , opening both the high and low side valves,and all seemed to be well.

When I removed the gage set hose I discovered that it was on backwards and so the schrader valve was not depressed, meaning that the lineset had not been evacuated.

When I discovered this I did the pump down procedure for 30 minutes, closed the high and low side valves , and vacuumed the lines for 15 minutes and then re opened the high and low side valves.

Am I completely screwed? Did the nitrogen in the lines get into the outdoor unit to raise havoc?

The unit seems to be functioning ok. A very small amount of the r410a refrigerant escaped while I was messing around with it. ]]> Geothermal bill498326 http://ecorenovator.org/forum/geothermal/2188-gage-set-hose-backwards.html http://ecorenovator.org/forum/geothermal/2177-mini-split-install-questions.html Thu, 19 Apr 2012 04:47:41 GMT I just installed a Gree Heat Pump 18,000 BTU.

The outdoor unit was pre-charged for 25 feet of line set. The unit it rated for 208/230 volts which I have 246 volts. I happened to have a buck transformer, although not necessary, I wired in the buck transformer so since it's a minus 16 volt I have 230 volts. So I installed with 25 feet of total line set so I wouldn't have to adjust the charge. I pulled a vacuum to 20 microns and it settled after an hour at 196 microns. Yes, it took a day of running my vacuum pump to get it to that level. So I fired it up and it works really great. Here's my question - finally. I went out and grabbed the line set and they were HOT in heat pump mode. So I attached a Fluke thermal clamp to the 1/2" line (largest) and temperature ranged from 118 to 149 degrees F. On high, it finally settled down at 141 degrees. The current is supposed to max out at 12.49 amperes in heat mode. I measured 11.1 amperes maximum. The company that sold me the unit says I need to add freon due to the high temperature of the line set. I haven't taken pressure tests (only one fitting on the 1/2" line). I went inside to check inlet and outlet temperatures but the room was 86 degrees from my testing so I switched to cooling and the did some indoor measurements. Outside temp=51 degrees, inlet temperature inside=86, outlet temperature=61 for a 25 degree delta. Later inlet temperature=69 degrees, 40 degrees outlet for 29 degree delta. Does it sound like I need to do anything such as add some R410a? I didn't want to open the schrader valve to connect a pressure gauge if I don't have to. The Service Manual says it can only be charged by weight anyway so that's complicated. The seller says if it's low on freon, the compressor will burn up but I'm not seeing excessive current draws like I expected. Looking for any input and thanks so much. ]]> Geothermal buster http://ecorenovator.org/forum/geothermal/2177-mini-split-install-questions.html http://ecorenovator.org/forum/geothermal/2176-26-seer-dc-inverter-thru-wall-window-air-conditioner.html Wed, 18 Apr 2012 22:41:21 GMT I've been expecting to see these "Inverter Thru wall / window air conditioners" show up..
26 SEER DC Inverter Thru wall / window air conditioner ductless mini split ac | eBay

The specs look nice. Anyone here interested in a nice 21 Seer window AC?

No fancy installation tools needed!

Edit:
Found this old review..

Sounds like a regular window AC.. Not an inverter unit..
Is the reviewer wrong? Or is someone scamming? ]]> Geothermal Xringer http://ecorenovator.org/forum/geothermal/2176-26-seer-dc-inverter-thru-wall-window-air-conditioner.html
