Tankless Water Heater Installation Costs in Greater Boston
Most tankless water heater installations we complete fall in this range:
Average: $8,000
What Affects the Price?
- Flow rate and household demand: homes that run several showers and appliances at once need a higher-capacity unit.
- Venting and gas line: gas tankless units need proper venting and often a larger gas line.
- Efficiency: higher-efficiency models cost more up front but can lower your operating costs.
- Your current setup: switching from a tank to tankless can mean new venting, gas and water connections.
You’ll see your options and pricing before any work begins.
Benefits of a Tankless Water Heater
- Endless hot water: water is heated as you use it, so you don’t run out.
- Saves space: a wall-mounted unit takes up far less room than a tank.
- Efficiency: there’s no tank of water kept hot around the clock.
