- Requirements
- Based on a "recharge the tanks" model
- 50K BTU Heating / day = XX BTU per hour (using 24 hours)
- 40K BTU Cooling (using off peak hours only = 12 hrs)
- Design / Selection
- Ideas
- use the natural effects of the basement and earth tubes to gain higher performance from the heat pump
- can we simplify the equipment (less is better)
- Design
- Air-to-Water Heat Pump
- Daikin Altherma Heat Pump
- Model:
- Daikin Altherma heat pump unit looks like the high end is coming to the US. Designed for our total problem...hot water, cooling, backup heat.
