Water Heater Repair in Hanover, PA

Gas heaters

Columbia Gas, not UGI

About 76% of Hanover homes heat with natural gas and 17% with electricity. The gas company is Columbia Gas of Pennsylvania, which lists ZIP 17331 in its service territory. In June 2026 the borough posted a Columbia Gas project to replace about 1,140 feet of main and upgrade about 55 service lines on Boundary Avenue, West Middle Street, Ruth Avenue and Doss Alley, expected to finish by the end of 2026.

A gas heater that won't stay lit usually has a worn thermocouple or flame sensor, a dirty pilot or a failing gas valve. About one in five Hanover homes is a rowhome or twin, and the median home dates from 1956, so it's worth having the vent checked whenever the heater is serviced. A heater that backdrafts can push exhaust into the basement.

Renters

Registration now, inspections still debated

Since January 2025, every rental unit in the borough must be registered each year, at $35 per unit paid by the owner. Inspections are a separate question. The borough held a town hall on adding them on September 1, 2026, and The Evening Sun reported two days later that the latest draft hadn't been scheduled for a vote.

The borough's housing standards already require properly installed water-heating facilities in every dwelling. If you rent and lose hot water, tell your landlord first, in writing if you can. If you own rentals, a heater that's near the end is cheaper to replace on your schedule than in the middle of a tenant's week.

Water and winter

Reservoir water across four towns

The borough's Municipal Water Works serves nearly 18,000 customers in Hanover, Penn Township, Conewago Township and McSherrystown. All of its water is surface water from reservoirs and intakes in York and Adams Counties, treated at one plant. Its pipes were laid over almost 150 years. The borough has finished its lead service line inventory and expects to post it online by 2027, and it has been swapping every meter for automatic-read Neptune meters since 2023.

NOAA's station four miles southwest of town averages about 122 nights a year at or below freezing, 11 nights at 10°F or colder and about 28 inches of snow. Colder water coming in means the burner runs longer, and a weak part often gives out in the first cold weeks.
