What to Watch for This Winter in Plymouth
- A 48-inch frost depth means exposed hydronic loops in Plymouth can freeze within hours of a no-heat failure when January lows hit 14°F.
- With 55% of Plymouth homes on natural gas from Eversource Gas, igniter and flame-sensor faults are the top cold-snap failures — a boiler that fires for three seconds and locks out needs a sensor check, not a reset.
- Only 39% of Plymouth homes predate 1960, but the Hydronic Baseboard systems here still need an annual tune-up before the 6,847-heating-degree-day season.
- If your home drops below 55°F, call (833) 873-0668 — average dispatch to Plymouth is about 41 minutes via Route 7.
