Why I Started Down This Rabbit Hole (And Why You Probably Will Too)
Last January, I woke up at 3 AM to the kind of cold that makes you question every life decision. The heating oil truck had been delayed by a snowstorm, my oil tank was hovering around a quarter tank, and the thermostat was already doing that thing where it clicks on, runs for ten minutes, then clicks off again like it's already given up on life. My upstairs bedrooms were hovering around 54°F, my daughter had three blankets on her bed, and I was lying there calculating whether it was cheaper to run the fireplace insert or just drive to the gas station and fill up some propane tanks.
That morning, I decided I was done reacting to heating season. I wanted to understand, once and for all, what the actual best heating option is for a typical New England home. So I spent the next four months talking to HVAC contractors, reading utility rebate programs, obsessively checking fuel prices on the Energy Information Administration website, and getting three different bids on a heat pump installation. What I found surprised me - not because any single technology is a magic bullet, but because the "obvious" choice isn't obvious at all depending on your specific situation.
This article is what I wish someone had handed me that night. It's not a sales pitch. It's what I learned from actual lived experience, real numbers, and conversations with people who install and service these systems for a living.
The Three Contenders: How They Stack Up in Simple Terms
Heating Oil
Heating oil is, to put it mildly, the old reliable of New England. If your house was built before 1990 and you're somewhere in Vermont, New Hampshire, or rural Massachusetts, there's a decent chance you have an oil-fired boiler or furnace chugging away in your basement right now. The infrastructure is everywhere. Oil delivery trucks can get to just about any address, even on back roads that would make a natural gas crew laugh.
The systems themselves are mature and robust. A well-maintained oil boiler from a brand like Thermo-Dynamics, Viessmann, or Buderus can last 20–30 years. The flame burns clean enough that modern oil systems achieve AFUE (Annual Fuel Utilization Efficiency) ratings of 85–95%, which is genuinely impressive. The Riello F5 and Wayne Combustion burners that you'll find in most residential setups are workhorses.
Here's what most people don't tell you about oil: it's not actually the fuel that's expensive - it's the inefficiency of your existing equipment. If you're running a 30-year-old boiler at 70% efficiency, you're throwing away 30 cents of every dollar on heat that goes straight up the chimney. Upgrading to a modern Energy King or Thermal Solutions condensing boiler can bring that efficiency up past 95%, which fundamentally changes your cost-per-BTU math.
Current heating oil prices in New England as of mid-2025 run roughly $3.50–$4.20 per gallon depending on your location and contract type. A typical 2,000 square foot home in New Hampshire or Vermont burns about 800–1,200 gallons per year with a modern efficient system. That's a range of roughly $2,800–$5,000 annually at current prices, though it swings dramatically - we've seen years where prices spiked to over $5.50/gallon and families were looking at $6,000+ heating bills.
Propane
Propane is the middle child of heating fuels - it's cleaner burning than oil, doesn't require a tank on your property if you go with a bulk delivery contract, and delivers a higher BTU output per dollar in some comparisons. But it has one massive, recurring problem: the price volatility is brutal, and unlike heating oil, you don't have a utility to call when your supplier raises prices 40% in a single winter.
Propane prices in New England have swung from around $2.00/gallon at the pump (for wholesale/negotiated contracts) to over $4.50/gallon during supply crunches. A typical propane tank for home heating holds 250–500 gallons and needs to be refilled 4–6 times per winter for a medium-sized home. If you're on a "will-call" pricing model where you order when you need it, you're often paying the spot price at the worst possible moment.
The systems themselves are excellent. Propane furnaces and boilers tend to be slightly more efficient than their oil counterparts, and they require less maintenance because propane burns cleaner (no soot buildup, fewer burner servicing calls). The Rinnai RU180i and Noritz EZ98 are tankless propane water heater options that also pair beautifully with hydronic heating systems. For furnaces, Carrier and Trane both make highly regarded propane units with AFUE ratings up to 98%.
The tank situation is worth discussing honestly. If you own your own propane tank (which you can do - it's a one-time purchase of roughly $700–$1,500 depending on size), you have more pricing flexibility. If you rent the tank from your supplier (which most people do because it avoids the upfront cost), you are essentially locked into that supplier's pricing. I've heard horror stories from friends in Maine where the rental tank agreement essentially meant paying $1–$2/gallon more than market rate because they couldn't switch suppliers without buying out an expensive contract.
Heat Pumps: The Contender That Actually Works in Cold Climates
Here's where the conversation has changed dramatically in the last five years, and where I think a lot of people (including the first contractor I called) are operating on outdated information. The conventional wisdom used to be that heat pumps are great in Florida but useless in Vermont. That is no longer true, and the evidence is accumulating fast.
Modern cold-climate heat pumps (sometimes abbreviated as "mini-splits" when referring to ductless systems) can extract heat from outdoor air even at temperatures well below freezing. The technology relies on variable-speed compressors and refrigerants with extremely low boiling points, and the efficiency gains in the past decade have been nothing short of extraordinary.
Some specific units worth knowing about:
Mitsubishi Zubadan MXZ-SM series - these are the ones that made cold-climate heat pumps mainstream in New England. Rated to operate at full heating capacity down to -13°F, with some models claiming output at -25°F. The Zubadan line was specifically designed for northern climates and was the first to genuinely challenge the "you need a backup heat source" assumption.
Daikin Quaternity - excellent efficiency ratings (HSPF up to 13+), operates in heating mode down to -4°F without capacity loss, and has a unique "floor warming" mode that several HVAC techs I spoke with specifically recommended for older New England homes with radiant floors.
Midea U-Shaped - the Midea U Blanc 12K BTU model has become a darling of the efficiency community for its affordability (often under $800 per indoor unit), quiet operation, and surprisingly solid cold-weather performance. It's not as robust as the Mitsubishi for the absolute coldest days, but for most of a New England winter it performs beautifully.
Carrier (Fujitsu) Glässer Series - the Carrier 36HP115V1A and equivalent Fujitsu models offer good cold-weather performance with the advantage of being sold through the massive Carrier distributor network, making parts and service much easier to find in rural areas than the Mitsubishi specialist network.
The efficiency story is genuinely compelling. A heat pump converts electricity into heating using a ratio of roughly 2.5–4.0 BTUs of heat per 1 BTU of electricity consumed, depending on the outdoor temperature. This is called the Coefficient of Performance (COP), and it means your heating costs can be dramatically lower than electric resistance heat even when electricity prices are factored in. A typical ductless mini-split system can heat a home for $800–$1,500 per year in electricity, depending on home size, insulation quality, and utility rates.
The Real Comparison: What Actually Matters to a Homeowner
Upfront Costs and Installation
This is where heat pumps face their biggest hurdle, and where the other two technologies have a structural advantage. Here are approximate installed costs as of 2025 in the New England market:
Heating oil boiler replacement:
Mid-range efficient boiler (Energy King, or similar): $5,500–$8,000 installed
High-end condensing boiler (Viessmann, Buderus): $9,000–$15,000 installed
Tank replacement (if needed): $1,500–$3,500 additional
Oil tank removal and remediation (if switching): $2,000–$6,000
Propane system installation:
Propane furnace or boiler: $6,000–$12,000 installed
Propane tank (owned, 500 gallon): $1,200–$1,800
Tank installation and gas line work: $1,500–$3,000
Total comparable to oil: $8,700–$16,800
Ductless cold-climate heat pump (most common New England installation):
Single-zone systems: $3,500–$6,500 per indoor unit, installed
Multi-zone systems (2–5 heads): $9,000–$18,000 total, installed
This typically includes the outdoor compressor unit, indoor units, mounting hardware, refrigerant lines, and electrical work.
Here's the catch that nobody advertising heat pumps wants to fully explain: ductless systems require wall-mounted indoor units. Some people love the look. Some people deeply hate it. If you have a historic New England home with formal living spaces where aesthetics matter, or a spouse who has already told you "absolutely no boxes on my walls," this is a real friction point that should factor into your decision honestly.
Ducted heat pumps are an alternative - they use your existing ductwork if you have a forced-air system - but the installation cost is higher (often $15,000–$25,000 for a full ducted system) and the efficiency in cold climates is sometimes slightly lower than the ductless options. The Carrier WeatherMaker 38MZQ and Trane XR15 are solid ducted heat pump options, but they represent a larger investment and are most commonly installed in newer construction or complete HVAC replacements.
Insurance Discounts: The Hidden Factor
This is the section that surprised me most in my research, and it genuinely affects the total cost of ownership in ways that don't show up in any heating fuel comparison calculator.
Many home insurance companies in New England offer premium discounts for homes heated by heat pumps - typically in the range of 5–15% off your annual premium. The rationale is that electric heat pump systems carry lower risk of oil spills, gas leaks, and fire compared to fossil fuel systems. Before you dismiss this as a small number, run the math on your own situation. If your annual homeowner's insurance is $2,400 and you get a 10% discount, that's $240 per year - and over a 15-year system lifespan that adds up to $3,600 in savings, which meaningfully shifts the heat pump payback calculation.
Some carriers that I'm aware of offering these discounts include Vermont Mutual, Plymouth Rock (in Massachusetts), and Concord Group Insurance in New Hampshire, though discount availability varies by location, policy details, and underwriter. Call your insurance agent and specifically ask about heating system discounts - most agents I spoke to said customers rarely ask about this.
Heating oil systems, particularly above-ground tanks, can actually increase your insurance premiums or require additional coverage in some cases, especially if the tank is older. Oil spill remediation costs can be substantial, and insurance companies know this.
Maintenance and Longevity
Oil systems require the most maintenance attention: annual burner servicing ($150–$300 per visit), periodic chimney cleaning ($200–$400), tank inspections, and filter changes. Neglecting this maintenance not only reduces efficiency but can void warranties and create safety risks. That said, if you stay on top of maintenance, a quality oil boiler can genuinely outlast two heat pump systems.
Propane systems are lower maintenance - no soot, cleaner burn, fewer moving parts in the burner assembly. Annual inspection is still recommended, but most HVAC technicians describe propane systems as "set and forget" compared to oil. Expect to pay $100–$200 per year for a basic inspection.
Heat pumps require less maintenance than fossil fuel systems in many ways - no combustion means no carbon monoxide risk, no annual burner cleaning, and no fuel system issues. The filters in the indoor units should be cleaned or replaced every 1–3 months depending on usage and whether you have pets. The outdoor unit should be kept clear of snow and debris. The refrigerant system is sealed and typically doesn't need attention for 10–15 years. Most mini-split manufacturers offer warranties of 5–12 years on the compressor, which is the expensive component.
The maintenance cost advantage of heat pumps is real but not as dramatic as some advocates suggest when you factor in the cost of servicing the multiple indoor units in a multi-zone system.
The Scenarios That Should Drive Your Decision
Here's where I'll be direct: the right answer depends heavily on your specific situation, and anyone who tells you there's a universal winner is selling you something.
Go with heating oil if:
You live in a very rural area where propane delivery is unreliable and electricity is expensive (above $0.25/kWh)
You already have a working, relatively new oil boiler and don't want to deal with the disruption of a full system swap
Your home has hot water baseboard heating (hydronic) that works perfectly and you don't want to switch to a different distribution system
You have a wood boiler as a primary or supplementary heat source and oil as a backup - this combination can be genuinely cost-effective
Go with propane if:
You live off the natural gas grid and want a cleaner-burning alternative to oil
You have a propane appliance already (dryer, stove, fireplace) and can negotiate a bundled delivery contract
You have the ability to buy your propane on the wholesale market through a co-op or buying group, which can reduce costs by 20–40% compared to retail delivery
Go with heat pumps if:
You are replacing an electric baseboard or resistance heat system - the cost comparison is night-and-day
You are doing a significant HVAC upgrade anyway and can bundle the installation costs into a larger renovation
Your utility company offers strong rebates (National Grid, Eversource, and Green Mountain Power all have heat pump incentive programs that can cover 25–50% of equipment costs in some cases)
You are building new construction or have the budget for a full ducted heat pump system
You care about reducing your home's carbon footprint and want to move toward an all-electric home
One scenario I want to specifically address: the "heat pump + oil backup" hybrid approach. This is increasingly popular in New England, and I think for many homeowners it's actually the smartest strategy. You install a cold-climate heat pump to handle 90% of your heating needs for most of the season - which in southern New England is October through April in many years. Then you keep your existing oil boiler as a backup for the 2–4 weeks per year when temperatures genuinely plummet below 5°F. This approach gives you the efficiency and cost savings of heat pumps for most days while maintaining complete redundancy for the worst-case scenarios. The installed cost is higher than either system alone (you're paying for both), but the flexibility is real and the backup system is already paid for from your existing setup.
What I'd Do If I Were You
After four months of research, three contractor bids, and one genuinely terrifying heating bill last February, here's where I landed personally - and I'll tell you that my neighbor with a completely different house, budget, and family situation probably made a different call, and that would be fine too.
I had a 2004 oil boiler with an AFUE of 86%, a 330-gallon buried oil tank, and two-story colonial with mostly hot water baseboard heating. I got a bid for a new Viessmann condensing boiler at $11,200, and I got a bid for a four-zone Mitsubishi MXZ-SM system at $16,400 after utility rebates. The payback math was roughly 8 years on the heat pump premium, which felt long but not unreasonable.
What decided it for me was a conversation with my HVAC contractor, who said something I haven't been able to shake: "The question isn't whether heat pumps are better in theory. The question is whether you trust that the technology will keep getting better and cheaper, and whether you're willing to accept a slightly longer payback in exchange for having a home that you're proud to show people."
I went with the heat pump system. We're now in our first full winter with it, and the monthly electricity bills during shoulder seasons (October, November, April, May) have been genuinely shocking in the best way - I've had months where my total heating/cooling cost was under $80. January was still expensive (about $340 for heating), but that was with multiple days below 0°F and I chose not to run the oil backup for most of them because the heat pump was keeping up better than I expected.
The honest truth is that I still have oil in the tank and I haven't cancelled my delivery contract. I still have the insurance discount and I still have the backup plan. The house is warmer, the utility bills are lower, and I don't have to lie awake at night wondering when the oil truck is coming.
That's the real answer. The technology has crossed a threshold. The economics, with rebates and efficiency credits, are genuinely competitive. And the quality of life improvement - walking into a warm house after a ski trip instead of a cold one - is real and worth something that no spreadsheet can fully capture.
Do your own homework, get three bids, check your utility's rebate programs, and talk to your insurance company before you sign anything. But if you've been putting off this decision because it felt overwhelming, I'm writing this to tell you that the time is now, the options are better than they've ever been, and you don't have to get it perfect - you just have to get started.
Prices, rebates, and incentive amounts cited in this article reflect conditions in the New England market as of 2025 and will vary by location, utility provider, equipment model, and installation specifics. Always obtain multiple bids and confirm rebate eligibility before making purchasing decisions.
