Windham climate
by the numbers
Windham's unique heating challenges
About 139 nights a year below freezing, when aging heating systems give out
The oldest blocks in town run heating systems decades older than the newer builds toward Salem
First frost typically lands around October 19
Seasonal timing
Windham's median first frost lands around October 19, matching Derry just north. A propane system that faltered during last winter's longest cold stretch tends to do it again once sustained demand begins after that.

People also ask
Yes. Vaporization rate depends on tank size, fill level and outdoor temperature, so a tank with fuel in it can still fail to deliver enough gas on a very cold night. A technician sizes the tank against the total appliance load.
That pattern points at the supply side rather than any single appliance. Regulator or tank issues affect everything downstream together, which is a useful clue when describing the problem on the phone.
Not worse, just different. It has its own supply constraints and delivery logistics, and it's what most of the town has available given where the mains end.
About 5 in a typical year, inside roughly 139 nights below freezing. Those are the nights that expose a supply system running with no margin, and Salem next door sees a similar count.
