Oil Savings Estimator

In about 60 seconds, estimate your monthly oil heating cost and compare it to a high‑efficiency upgrade (heat pump, hybrid, or high‑efficiency oil). We show a range and the assumptions used.

Optional PDF report

1) Location & home

ZIP code Optional. Used only as a label. We do not auto-look up your home. Climate band * If you're in our Eastern PA service area, choose Cold. Heated square footage * How many floors? Windows — roughly how much glass? Optional. Helps us size cooling properly rather than guessing.

2) Current oil system

Primary oil system type * If you have multiple systems, choose the one that does most of the heating. Approx. age/condition * Heat delivery (boiler) * Hot water coils behave like ducted distribution. Duct location (current) * Duct location can significantly change operating cost. Ductwork condition (current) Leaky ductwork can add losses and raise bills.

3) Hot water (major accuracy factor)

Does oil also make hot water? * Tankless coils can burn a surprising amount of oil year-round. After upgrade: hot water method If you select Not sure, we’ll assume a heat pump water heater for the estimate (often the lowest operating cost). Indirect applies only when you have an oil boiler. Household size (people) Helps estimate hot water use (and hot water cost).

4) Your oil usage / cost

I know my gallons (best) I know my annual spend Estimate from home size

Year built (best guess) A rough decade is fine. Insulation / air sealing (optional) Helps tighten the estimate when you don’t know gallons/spend. Gallons delivered (last 12 months) * Annual oil spend (approx) * We anchor your “current cost” to this number. Average oil price ($/gal) If blank, we use a default and widen the range.

If you heat partially with wood/pellets/etc., your gallons already reflect that—results will reflect your current oil usage.

5) Upgrade option

Compare against * Heat pump efficiency tier * For best accuracy, enter COP/HSPF in Advanced. % of heating served by heat pump

85%

Lower % means more oil backup used in colder weather. Reuse existing ductwork? Duct location (after upgrade) If you reuse existing ducts, this is assumed to match your current ducts. Ductwork condition (after upgrade) If you select “No (new ducts)” above, we assume improved/sealed unless you change this. New oil system type

6) Electricity rate (important for accuracy)

All-in electric rate (¢/kWh) Use your all-in rate (total bill ÷ total kWh), not just the supply rate. Example: $321 ÷ 1680 kWh = 19.1¢/kWh. Quick rate calculator (optional)

This fills the all-in rate field above. If you only know a supply rate like ~5¢, your total is usually higher after delivery & fees. Typical monthly electric bill (lights/appliances) (optional) Optional. Use a mild month (Apr/May/Oct) when heating & A/C are low. We’ll use this to show an estimated total electric bill after the upgrade. This does not change the savings math.

Advanced assumptions (optional)

These can improve accuracy if you know your equipment specs. We always show assumptions in results.

Override current oil seasonal efficiency (0.50–0.92) Override heat pump seasonal COP (1.8–4.5) OR enter heat pump HSPF / HSPF2 (heating) We convert: COP ≈ HSPF ÷ 3.412 Optional SEER / SEER2 (cooling) Cooling rating does not directly determine heating savings. Override HPWH COP (if using HPWH) Hot water temp rise (°F) Hot water use per person (gal/day)
