Chesapeake Plumbing Supply in Baltimore: Tankless Water Heater Installation and Repair

Chesapeake Plumbing Supply is a licensed plumbing contractor and retailer on Eastern Avenue that handles tankless water heater installation, repair, and maintenance across Baltimore. The business stocks equipment and performs work for residential properties in the city, with a focus on the efficiency gains and space savings tankless systems offer over conventional tank models.

What Chesapeake Plumbing Supply actually is

Chesapeake Plumbing Supply operates as both a supply house and a full-service installation and repair shop. Licensed plumbers on staff perform work in customer homes; the retail side sells fixtures, parts, and complete tankless units to homeowners and contractors. The operation is small enough to handle direct customer calls but large enough to stock major brands including Navien, Rinnai, and Takagi. Most jobs fall into either new installation for renovation projects or repair and descaling of existing systems.

Services and pricing

Installation of a new tankless water heater runs $2,500 to $4,500 depending on whether the existing gas line and venting infrastructure can be reused. If new vents or gas lines are required, add $800 to $1,200. Service calls for repair or annual descaling cost $150 to $250, with descaling alone (recommended once yearly on hard-water systems) typically falling at the lower end. Replacement of internal parts such as heat exchangers or flow sensors ranges from $400 to $1,000 plus labor. The shop charges $95 per hour for labor on service calls. Request a quote by phone; most estimates are given over the phone after a brief description of the existing system.

How tankless systems compare to tank water heaters in Baltimore

Tankless units deliver hot water on demand without storing it, meaning no standby heat loss and a much smaller physical footprint. A tank model occupies a 4-by-2-foot floor space; a tankless unit hangs on a wall and measures roughly 2 feet tall. Tank units cost $600 to $1,200 and typically last 10 to 12 years. A tankless unit costs $1,500 to $3,000 and lasts 15 to 20 years. Energy savings are real but modest in Baltimore's temperate climate: most households see a 15 to 20 percent reduction in water heating costs, not the 30 to 40 percent marketed nationally. Tankless units perform well in single-family homes but can struggle to supply simultaneous hot water to multiple showers and appliances without undersizing the unit. Tank models have no such limitation. Chesapeake's plumbers will advise whether a tankless unit suits your home's layout and usage; many Baltimore homeowners upgrading a single bathroom choose tankless, while larger families often stay with tanks.

Who it suits and who it does not

Tankless systems suit homeowners with limited basement or utility space, those planning to stay in a home long enough to recoup the installation premium (at least seven years), and households with moderate simultaneous hot-water demand. They work well in condos and row houses where floor space is tight. Families with multiple bathrooms, high-flow fixtures, or frequent simultaneous use should choose a tank model unless they are willing to pay for an oversized tankless unit (which increases cost). Homeowners in areas of Baltimore with very hard water should expect annual descaling; those unwilling to commit to maintenance may prefer tank models, which require less frequent service.

What the first visit involves

Call Chesapeake Plumbing Supply with your current water heater model and age, your gas type (natural or propane), and how many bathrooms your home has. A plumber will schedule a time to inspect the existing unit, check gas and venting lines, and measure space constraints. This walk-through typically lasts 30 to 45 minutes and costs nothing if you proceed with an estimate. The plumber will then provide a written quote for installation, including any modifications to gas or vent lines. Most Baltimore installations happen within two to four weeks of booking.

Hours, parking, and logistics

Chesapeake Plumbing Supply is open Monday through Friday, 8 a.m. to 5 p.m., and Saturday, 9 a.m. to 1 p.m. (verify current hours by phone). On-site parking is available. Service calls are scheduled by appointment only; emergency service outside regular hours is not offered. The shop accepts calls at their Eastern Avenue location to set appointments or ask technical questions about existing units.

Chesapeake Plumbing Supply provides transparent pricing and honest guidance about whether a tankless unit makes sense for your home, which separates it from retailers who push tankless systems as a blanket upgrade.
