About This Service
Tankless water heater installation in Leawood delivers continuous hot water on demand — no tank to run empty, no waiting for recovery. For larger Leawood homes with multiple bathrooms, or for homeowners who want the longest-lasting, most efficient option, tankless is the go-to choice.
Tankless units heat water as it flows through the unit rather than storing it in a tank. The result: hot water that never runs out, a compact wall-mounted unit that frees up floor space, and a lifespan of 20+ years (compared to 8-12 for tank units). Energy savings come from not keeping 40-75 gallons of water hot 24/7.
Installation in Leawood typically involves removing the existing water heater (if converting from tank), upsizing the gas line to handle the higher BTU demand of a tankless burner, and installing new direct-vent exhaust through an exterior wall or roof. The unit is then mounted, connected, and tested at full flow to confirm GPM capacity matches the home's needs.
GPM (gallons per minute) is how tankless capacity is measured. A typical Leawood home needs 7-10 GPM to run two showers and a kitchen faucet simultaneously. Larger homes in Mission Farms, Hallbrook, or Leawood Estates may need a higher-capacity unit or a dual-unit setup. Rinnai, Navien, Rheem, and other major brands are all available — each has different features, efficiency ratings, and warranty tiers.
One important consideration for Kansas City: tankless units require annual descaling due to KC's hard water. Mineral buildup in the heat exchanger reduces efficiency and can shorten lifespan if left unchecked. Annual maintenance keeps the unit running at peak performance for decades.

What to Know
Tankless water heaters last 20+ years compared to 8-12 for tank units, making them a strong long-term investment.
Gas tankless installation often requires upsizing the gas line from 1/2" to 3/4" to handle the higher BTU demand. This is assessed during the quoting process.
Venting requirements differ from tank units. Tankless heaters use direct vent (sealed combustion) which may require new PVC or stainless steel venting through an exterior wall or roof.
GPM (gallons per minute) is how tankless capacity is measured. A typical Leawood home needs 7-10 GPM to run two showers and a dishwasher simultaneously.
Leawood hard water requires annual descaling of tankless heat exchangers. Without it, mineral buildup reduces efficiency and shortens lifespan. Vinegar flush kits are available, or schedule annual maintenance.
Tankless units are compact and wall-mounted, freeing up floor space in the basement, utility room, or garage.
