Calculations
- Coefficient of Performance. Note that the Europeans have a more sophisticated Seasonal COP (SCOP) [1]
- US has SEER - Seasonal Energy Efficiency Ratio[2]
- Heatuing Seasonal Performance Factor - [3]
- Cost - note that the above states $7-11k system cost - large value that the owner-builder can create as the hardware involved is only 1/5 of the cost.
- Ground Source - tubing install cost is $13-24k according to above video. Extraction is 10-30W/meter of tubing. Water source heat pump is a bit better, and has extraction of 20-60W/meter of tubing.
Sourcing
- 2 Ton, 21 SEER, $1389, but only to -4F. [4]
- 2 Ton, 21 SEER, $1388, down to -13F [5]
- 2 Ton, 21 SEER, $1788 2 zone - but down to -4F [6]
- 2 Ton 3 zone 21 Seer $2k but down to -4F - [7]
- 2 ton 1 zone 21 SEER, 10.5 HSPF down to -22F R410 $1480[8]
- Mr. Cool DIY only goes from 5F [9].
