Is a heat pump water heater a good choice?
We are designing for new construction of a family home (five people) in Omaha, NE. Our average daily water use in our current home is around 200 gallons. We estimate that this could increase somewhat as we will be adding a shower and the kids will be taking more showers. I’ve looked at heat pump water heaters like the Rheem HP-50 (http://www.rheem.com/product.aspx?id=BF7C55FB-67BA-41B5-8EEA-B7022B9DC671) or the GE Geospring (http://www.geappliances.com/heat-pump-hot-water-heater/). We also may use a WaterFurnace Synergy 3D ground source heat pump (http://www.waterfurnace.com/products.aspx?prd=Synergy3D) for our heating and cooling. I believe this unit has ability for DHW pre-heating.
Given the situation described above, does anyone have feedback on these heat pumps or suggestions for alternative solutions? Our goal is long-term water heating efficiency. We plan to use water conservation fixtures throughout the house, use Energy Star appliances, insulate our hot water pipes, and maintain the equipment in a conditioned basement mechanical room.
Thanks in advance for your feedback.
