The cost to install a water heater in Bethesda ranges from $1,120 to $4,340, with most homeowners paying around $2,230. Your actual cost depends on several factors specific to your home and the Washington-Arlington market.

🔌
Tank Vs Tankless

Tankless units cost 2–3x more upfront but last longer and save on energy bills. Tank water heaters are cheaper to install but less efficient over time.

Gas Vs Electric

Gas water heaters require venting and a gas line, adding installation complexity. Electric units are simpler to install but may cost more to operate in areas with high electricity rates.

Venting Requirements

Power-vent and direct-vent units need PVC or stainless steel venting through a wall or roof, adding $300–$800 in materials and labor.

🔧
Old Unit Disposal

Draining and removing the old water heater adds $50–$150 to the job. Tank units are heavy (120+ lbs) and require careful handling.

🏗️
Expansion Tank

Many codes now require a thermal expansion tank when replacing a water heater, adding $50–$150 for the tank and installation.

The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
