Folcroft Homes by the Numbers

2,866housing units
1960median year built
73%of homes heated by gas
73%owner-occupied

In Folcroft about 73% of homes are heated with gas, which makes gas-fired tankless units, and the gas pressure and venting problems that come with them, the common repair. With a median build year of 1960, many homes in Folcroft were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. About 73% of homes are owner-occupied and about 86% are single-family, so most repair decisions here are the homeowner's own.

Folcroft covers about 1.2 square miles and holds roughly 6,748 residents, around 5,398 per square mile: suburban in density, with a mix of detached homes and townhomes. Among the 688 Pennsylvania places we cover, it ranks number 106 by population.

Local climate

Folcroft Weather and Water Temperature

26 ftabove sea level
56°Fyearly average air
100 nightsat or below freezing
~44°Fwinter tap water

Winter here is long: roughly 100 nights a year drop to freezing or below, and the lowest reading in the past three years was about 3°F. Condensate traps, supply stubs in unheated spaces and vent caps are the usual victims, so a tankless unit in Folcroft deserves a close look before the cold sets in.

In Folcroft the cold tap is probably around 44°F in winter and 67°F in summer, based on a January average of 33°F, a July average of 78°F and a yearly average of 56°F. Heating that water to 120°F takes a rise of about 76°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 4.7 gallons per minute, compared with roughly 6.7 in summer when the rise is only about 53°F.

For comparison, a shower draws roughly 2 gallons per minute, so two at once plus the dishwasher can pass the winter figure. If the water goes lukewarm only when several taps run, the unit is likely maxed out; if it goes lukewarm at one tap, the cause is more often scale, a flow sensor or the flame.

How much does tankless water heater repair in Folcroft, PA cost?

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.

Why does my tankless water heater go hot then cold?

A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor. Around Folcroft the winter supply is likely near 44°F, which limits a typical gas unit to roughly 4.7 gallons per minute at 120°F, so a swing that only happens with several taps open is usually that limit.

How long does a tankless water heater last?

A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10. In Folcroft the heat exchanger works through a rise of about 76°F on a typical winter day, which is why flushing on schedule matters there.

Can a tankless water heater be repaired?

Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
