What Tankless Water Heater Installation Involves
A tankless unit must be integrated with the home’s water supply, gas or electrical service, and venting system. We install temperature and pressure relief valves and add expansion tanks where needed, then verify all connections against current plumbing and building codes.
A complete installation addresses several components:
- Water Connections: Supply and hot water lines must be properly connected to the new unit.
- Fuel or Electrical Service: The available gas line or electrical capacity must support the selected model.
- Venting: Gas-fired units require compatible, dedicated venting rather than the vent used by an older tank water heater.
- Safety Devices: Relief valves and other required components must be correctly placed and connected.
A tank-to-tankless conversion is usually more involved than replacing an existing tankless model. Depending on the home and equipment, the project may require gas line upsizing, new venting, a dedicated high-amperage circuit, or an electrical panel upgrade.
Gas vs. Electric Tankless Water Heaters
The right fuel type depends on peak demand and the utilities already in your home. Gas-fired tankless units generally support higher flow rates, while a whole-house electric model can place substantial demand on the electrical system.
Capacity is measured in gallons per minute (GPM), meaning the volume of hot water a unit can deliver each minute under specified conditions. Proper sizing accounts for fixtures that may run at the same time, such as two showers, a dishwasher, and a washing machine. An undersized unit can produce temperature drops or reduced flow when demand spikes.
Wall-Mounted Equipment With a Longer Service Life
Tankless water heaters mount directly on a wall, freeing the floor space a conventional storage tank would occupy. That compact footprint is particularly useful in small utility rooms, closets, and tight mechanical spaces.
A tankless system typically lasts around 20 years or longer, while standard tank models commonly last 10 to 15 years. Actual service life depends on water quality, household use, installation quality, and maintenance.

Annual Tankless Water Heater Maintenance
Most tankless water heaters should receive professional maintenance at least once a year, though the right schedule depends on household use, local water conditions, and manufacturer requirements.
Annual service typically includes descaling, which removes mineral deposits from the heat exchanger and internal water passages. Left unaddressed, that buildup is a leading cause of reduced performance and overheating. Every new system we install is fully warrantied, and our maintenance plans help preserve performance while reducing the risk of avoidable repairs.
