Tankless Water Heater in Woodbridge, VA

Reasons Woodbridge owners make the switch

• The original tank in a split-level or townhouse is nearing the end of its life
• Hot water runs out during busy mornings in a full household
• You want the floor space a tank occupies in a small utility closet
• A tankless unit already installed shows codes or loses flow
• You are finishing a basement and want the heater on the wall instead of the floor

Local conditions in Woodbridge

Most of Woodbridge gets water and sewer from Prince William Water, which buys Occoquan Reservoir water treated at Fairfax Water's Griffith plant. Parts of the wider Woodbridge postal area around Dale City are served by Virginia American Water's Prince William system instead, so check your bill. Prince William Water rates its water as moderately hard, 3.5 to 7.0 grains per gallon (60 to 120 mg/L). That is on the gentler side for the region, but scale still builds in a heat exchanger over time, so service valves and a periodic flush remain part of the plan.

Prince William County publishes a permit guide written for gas-fired tankless heaters in existing homes. It calls for a gas permit covering gas piping and venting, a plumbing permit when water piping is extended more than 10 feet or the pipe material changes, and an electrical permit if a new circuit is needed. The Building Development Division is at 5 County Complex Court (703-792-6930).

Both Columbia Gas of Virginia and Washington Gas operate in Prince William County, so the utility on your gas bill is the one that serves you. If you smell gas, leave the house, then call 911 and that utility's emergency number from outside.

What moves the price

• Upsizing gas pipe from the meter for a high-input burner
• The vent route, from a short sidewall run to a longer path through a finished basement
• Extending water lines more than 10 feet, which adds a plumbing permit
• A new electrical circuit for controls or an electric model
• Condensate drainage for a high-efficiency unit

What happens when you call

You are connected with an independent plumber who works in Woodbridge. Mention your current heater's size and fuel, where it sits and how many bathrooms you have. The plumber checks the gas supply and vent options before quoting and normally pulls the County permits.
