 We have an oil-fueled boiler forced hot water heating system. We have a single window air conditioner that the heat pumps would replace.  Here are the cost factors for our situation. We have an oil-fueled boiler forced hot water heating system.

-"Heatpump" is cost of heat pumps installed.  "Heatpump w/agreement" is when we also sign an agreement saying we will only use oil to heat the house in an emergency. +Assuming for the purpose of this analysis:
-| |Heatpump|Heatpump w/agreement|Oil Boiler only (current situation)| +
-|Equipment|23000|18000|0|cost of added equipment| +
-|Maintenance/yr|835|200| +
-|Electricity increment estimate/yr|1200|1200|0|assuming extra $100/month for heat pumps| +
-|Est cost oil, 700gal/yr, $4/gal|100 gal@$4/gal=400 |100 gal@$4/gal |700 gal@$4/gal=2800|//need oil to heat hot water//| +
-Also assuming for the purpose of this analysis:+
   * Energy costs stay the same over the analysis period (oil and electricity)   * Energy costs stay the same over the analysis period (oil and electricity)
   * Maintenance costs stay the same over the analysis period   * Maintenance costs stay the same over the analysis period
