Tankless Water Heater in Clifton, VA

Signs it is worth looking at tankless

• A propane or electric tank is aging, and you want to stop heating stored water all day
• Hot water runs out when guests stay
• The heater sits in an old cellar or crawlspace where a tank leak would do damage
• An existing propane tankless unit is losing flow or showing codes
• Well water leaves sediment or scale in fixtures

Clifton conditions

The Town of Clifton is a small historic village in southwestern Fairfax County, a National Historic District with wooded lots and some of the oldest housing in the area. There is no town water system: homes rely on private wells, and new houses must have room for a well and an onsite wastewater field. Public sewer is available only to existing buildings that meet Fairfax County guidelines, with County approval.

There is no gas utility either. Town residences keep their own propane tanks. A propane tankless unit is a common fit, but the tank, regulator and line must supply the burner at full fire, which a plumber will check. Electric tankless units are another option where the electrical service can carry them. If you smell propane, leave the house, then call 911 and your propane supplier from outside.

Well water varies by property. A recent well test shows hardness, iron and sediment, which decide whether the unit needs a sediment filter, a softener or both. A tankless unit also needs steady flow and pressure from the well pump to fire reliably.

What drives the cost

• Propane line and regulator sizing, or electrical upgrades for an electric unit
• Venting from an older house with thick walls or limited access
• Filtration or softening based on the well test
• Condensate drainage for a high-efficiency propane model
• Permits: Fairfax County Land Development Services issues them, and the Mayor or designee must sign building permit applications first; for interior-only work, the Town clerk can provide a letter to the County
