We are seeking a single family home mechanical engineer familiar with electric heat pump options

We are interested in options to replace a natural gas furnace and natural gas hot water heater with electric heat pump furnace and electric heat pump hot water heater. The house is small (1,200 conditioned SF + 900 SF basement that is not actively conditioned but receives air leakage from the conditioned space above, that we would like to more consciously control to prevent pipe freezing but otherwise be efficient).
