We did, or rather received such calculations from the providers. Today and here, depending when you retire and what your plans after that are, you might think twice about getting a geothermal one. The air-water would fit as the 1:1 replacement for the oil heating we have, with the promise of barely breaking even. NB: when you replace/upgrade an existing pump, some costs won't come again.
