The Hedge Propane Country Has Been Waiting For
Big pieces of Londonderry sit past the end of the natural gas lines, which means whole subdivisions — the 80s streets, the 90s cul-de-sacs, the 2000s colonials off Route 102 — heat by the gallon, at whatever the propane market decides this winter. A cold-climate heat pump moves most of that load onto electricity and turns the tank into a backup instead of a dependency.
Independent local installers put these systems into orchard-country homes every month: full conversions, dual-fuel setups that keep the existing propane furnace for the deepest cold, and ductless heads for the bonus rooms builder ductwork never quite reached. Licensed, insured, and honest about what your particular house needs.
Where Heat Pumps Earn Their Keep Here
- Tank-fed subdivisions beyond the gas corridors — where a mild winter's fill-ups sting and a cold one's hurt
- Dual-fuel conversions — the heat pump carries the season, the propane furnace you already own covers the single-digit mornings
- Homes replacing furnace and AC together — one outdoor unit takes over both jobs instead of buying two machines
- Bonus rooms and additions the original trunk line never served — a ductless head fixes the coldest room in the house
- Older homes near the orchards ready to retire an oil burner without running new ductwork
Will It Keep Up in a Londonderry January?
The honest answer: a properly sized cold-climate unit, yes — current equipment is rated to hold output well below 0°F. The failures you hear about are sizing failures, not technology failures: a unit picked off square footage instead of a real load calculation, bolted onto a 90s colonial with builder insulation. That's why independent local installers start with the load math, and why dual-fuel remains a popular Londonderry answer — the propane furnace stays in the basement as insurance you rarely burn.

Londonderry Heat Pump Questions
Can a heat pump really replace my propane furnace entirely?
For a lot of the housing stock here, yes — cold-climate equipment holds its output far below zero, and full conversions are now routine work. That said, many Londonderry homeowners choose dual-fuel instead, keeping the propane furnace to fire only on the handful of brutal mornings each winter. Which path makes sense depends on the furnace's age and your tank contract — a licensed installer will estimate both.
My whole street is on propane — why is everyone suddenly talking about heat pumps?
Because the subdivisions that were plumbed for propane in the 80s and 90s are watching their original and second-generation systems age out at the same time, right as heat pump technology matured for New Hampshire winters. When a replacement is due anyway, the fill-up bill becomes a fair target. It's less a trend than a street full of neighbors doing the same math within a few years of each other.
