 ====Analysis & Comparison, heat pump vs oil boiler==== ====Analysis & Comparison, heat pump vs oil boiler====
 We got a quote from a company for the cost of a whole-house solution.  There are two rebates available to us, approx $5k since we're going whole-house, and $10k if we also sign an agreement that we will only use oil heat in an emergency. We got a quote from a company for the cost of a whole-house solution.  There are two rebates available to us, approx $5k since we're going whole-house, and $10k if we also sign an agreement that we will only use oil heat in an emergency.
